NIH may destroy human brain collection
By Steve Mitchell Medical Correspondent
Washington, DC, Mar. 24 (UPI) -- The National Institutes of Health may
discard part or all of a rare collection that includes hundreds of human brain
samples from patients that suffered from a disorder similar to mad cow disease
-- unless another researcher or institution takes them on, United Press
International has learned.
Several scientists said the collection, which is held by the NIH's
National Institute for Neurological Disorders and Stroke in Bethesda, Md. -- and
includes brains and other tissue samples from people afflicted with the
brain-wasting illness Creutzfeldt Jakob disease -- is irreplaceable and could
even provide insight into treatments for the fatal disorder.
Currently, there is no cure for CJD and patients typically die within a
year after symptoms begin.
However, NIH officials in control of the collection's fate told UPI the
remaining samples are of little scientific value and may be disposed of if
researchers outside the agency do not claim it. That position stands in sharp
contrast with CJD experts who thought the collection should be preserved.
"It's invaluable," said Dr. Paul Brown, former medical director of the
NIH's Laboratory for Central Nervous System Studies, whose expertise is in CJD
and mad cow disease (also known as bovine spongiform encephalopathy, or BSE).
The collection is badly in need of organization and no one is certain how
many brains or other tissue samples it contains, said Brown, who worked with the
collection since its inception in the 1960's until his retirement last year.
There could be brains, blood, spinal fluid and various other tissues from 1,000
people or more, he said. Some of the specimens would be of scientific use today,
he said.
"This collection has the unique value of stretching back to the beginning
of when these diseases were discovered," Brown told UPI, noting that the first
samples were obtained in 1963. "It would be as though you had in your hands the
possibility of finding out when AIDS started."
Bruce Johnson, a former technician at the CNSS lab who worked extensively
with the collection before he retired in 2003, told UPI he was told "in two
years they (NIH officials)are going to destroy it, if nobody wants it."
Eugene Major, acting director of the basic neuroscience program at the
NIH, said no specific timeframe had been established.
"We have not set a firm deadline date," Major told UPI. "We are working
very hard with investigators that we know in order to be able to make sure that
whatever we deem is valuable is potentially kept here." Some samples already
have been determined not to have any research value and have been "removed and
disposed of," he said.
Others samples have been given out to Dr. David Asher at the Food and Drug
Administration and Pierluigi Gambetti at the National Prion Disease Pathology
Surveillance Center in Cleveland, Ohio.
Major maintained the remaining collection was not particularly valuable
for research. "Whatever had been collected here that has not already been
distributed to responsible investigators who could use them really has very
little remaining value," he said.
Neither Asher nor Gambetti returned phone calls from UPI, but Brown said
he thought Asher had received only a dozen or two samples at most and Gambetti
had not received much at all.
Neil Cashman, a brain-disease researcher at the University of Toronto's
Center for Research in Neurodegenerative Diseases -- who has tried to obtain the
collection from the NIH -- said it was priceless.
"It would be like destroying an art museum," Cashman told UPI. "There's
all this information and insight that's locked up in these tissues and if it's
destroyed it will be lost forever."
The Memorial Institute for Neurodegenerative Diseases Inc., a non-profit
organization consisting of more than 40 university and institute researchers
from the United States, Canada, United Kingdom and France, also thinks the brain
collection is invaluable.
"It is the opinion of the Board of Directors ... of The MIND Inc., that
the ... brain bank should not be broken up nor destroyed," said Harry E. Peery,
MIND's executive director, in a letter to UPI. "We believe that this collection
is of inestimable research value and should be kept intact."
The institute, at the University of Saskatchewan in Saskatoon, applied for
possession of the collection in early 2004, but received a letter from the NINDS
indicating the fate of the collection had not yet been determined.
"We have heard nothing further since that time" and continue to be
interested in acquiring the complete collection, Peery said.
CJD belongs to a group of rare, brain-wasting disorders that are little
understood, incurable and fatal. This includes mad cow disease in cows, chronic
wasting disease in deer and elk. The most infamous of these illnesses in humans
is variant CJD, which people can contract from eating beef products infected
with the mad-cow pathogen.
Although vCJD has infected more than 154 people worldwide, only one case
has ever been detected in the United States -- in a Florida woman who is thought
to have contracted the disease while living in the United Kingdom. However, the
NIH brain samples have never been screened for vCJD -- something Johnson thinks
is critically important.
"No one has ever looked to see if any American (in the collection) in the
past had variant CJD," Johnson said. "You think it would be required that they
do that. You think it would be a Congressional mandate that they test these
brains: 'Let's see if we've got this disease in our country.'"
Johnson noted at least one brain in the collection he personally had
examined -- from a French woman collected in 1971 -- showed evidence of possible
vCJD infection, but the sample needed further study to be sure.
Other samples in the collection include the brains of patients who were
only 16 years old when they were diagnosed with CJD. This would be unusual for
sporadic CJD, because generally it strikes those over age 60. Variant CJD, on
the other hand, typically occurs in patients in their 20s or younger.
"I thought it was absolutely vital (to test these brains)," Johnson said.
"Maybe there's a dozen cases in there of variant CJD."
Major disagreed. "There's really no reason to do that," he said. "The
effort it would take to screen those samples ... would not give us any new
insights into variant CJD beyond what it is we already know."
Johnson said he was frustrated with the NIH administration's lack of
interest in preserving the collection or testing for vCJD. "They don't
understand," he said, "they honest-to-god don't understand what it's all about."
Patient advocates also objected to the possible destruction of the brains.
Terry Singeltary, whose mother died of a type of CJD called Heidenhain
variant in 1997, said he is outraged and families of other CJD victims probably
will be, too.
"A lot of these families went through a lot of heartache and a lot of
trouble to get these brain samples to the NIH," Singeltary told UPI. "Now
they're just going to discard them because they're not of scientific use? That's
just asinine. That stuff is valuable information."
Graham Steel, vice-chair of the Human BSE Foundation in the United
Kingdom, told UPI, "The potential loss of such important tissue samples would be
a massive blow for TSE (the group of diseases that includes CJD and BSE)
research in the United States. This should not be allowed to happen."
Singeltary noted there currently is no cure for these diseases. "If you
don't have any answers yet, why would you throw these specimens away?" he asked.
He added that more sensitive tests are just becoming available and could
help determine the origin of some of the CJD cases. "We've all been sitting
around waiting for more sensitive tests to get validated because we want
answers," he said.
"You know, it must be an embarrassment," Johnson said. "Some Senator is
going to eventually say 'What is NIH doing about mad cow disease?' And people
are going to scratch their heads and say 'not much'." He added, "What's going to
happen (is) one of these senators or their wife is going to develop spontaneous
CJD one day and ... there's going to be hell raised and they're going to ask,
'Why isn't NIH working on this?'"

I will first post the beginning of my letter to these officials asking for
help.
I will then post the letters from the Honorable Senator Cornyn and would
like to thank him for pursuing this for us, and getting this in writing. It
meant a lot to all of us.
Thanks to Steve Mitchell of UPI for his continued efforts to find the truth
about all human and animal TSEs, and his continued efforts in trying to keep the
USDA/APHIS/FDA/CDC/NIH Federal Officials honest and forth coming. However, it's
kinda like pulling teeth sometimes, all for the safety and security of US
citizens i am sure.
IN the reply from NIH back to Senator Cornyn on this issue, there were some
concerns of mine that i will bring up and comment on later below...TSS

The Honorable John CornynUnited States SenatorOccidental Tower5005 LBJ
Freeway, Suite 1150Dallas, Texas 75244-6199
Dear Senator Cornyn:
Your letter to the National Institutes of Health (NIH) forwarding
correspondence from Mr. Terry S. Singeltary, Sr., has been forwarded to me for
reply. Mr. Singeltary is concerned about the preservation of Creutzfeldt-Jakob
disease (CJD) brain samples that have been maintained by the National Institute
of Neurological Disorders and Stroke (NINDS) Intramural Research programfor many
years.
I am sorry to learn that Mr. Singeltary's mother died of CJD and can
certainly understand hisdesire that any tissues that could help investigators
unravel the puzzle of this deadly disease are preserved. I hope he will be
pleased to learn that all the brains and other tissues with potential to help
scientists learn about CJD are, and will continue to be, conserved. (The tissues
that are discarded are those that have either decayed to an extent that renders
them no longer appropriate for research or those for which we do not have
sufficient identification.)
The purpose of gathering these brains and tissues is to help scientists
learn about CJD.
To that end, some of the NINDS-held samples are distributed to
investigators who can demonstrate that they have a compelling research or public
health need for such materials. For example, samples have been transferred to
NIH grantee Dr. Pierluigi Gambetti, who heads the National Prion Diseases
Pathology Surveillance Center at Case Western Reserve University in Ohio and
works with the Centers for Disease Control and Prevention to monitor all cases
of CJD in the United States. Dr. Gambetti studies the tissues to learn about the
formation, physical and chemical properties, and pathogenic mechanisms of prion
proteins, which are believed to be involved in the cause of CJD. Samples have
also been transferred to Dr. David Asher, at the U.S. Food and Drug
Administration, for use in assessing a potential diagnostic test for CJD.
Page 2 - The Honorable John Cornyn
in closing, we know that donating organs and tissue from loved ones is a
very difficult and personal choice that must often be made at the most stressful
of times. We at the NINDS are grateful to those stalwart family members who make
this choice in the selfless hope that it will help others afflicted with CJD. We
also know the invaluable contribution such donations make to the advancement of
medical science, and we are dedicated to the preservation of all of the tissue
samples that can help in our efforts to overcome CJD.
I hope this information is helpful to you in responding to Mr.
Singeltary.
Sincerely,
Story C. Landis, Ph.D.
Director, National Institute ofNeurological Disorders and Stroke
==================================
Greetings,
THE concerns i wanted to mention are ;
A. The distribution of those tissue samples and how they are
distributed.
I think more people researching this agent (especially sporadic CJD) should
be able to obtain the tissue samples. THE political crap below must stop, or
what i like to call BSeee ;
=============================
Major previously said, however, that efforts to inform researchers of the
availability of the collection were already underway and included informing NIH
grantees. He added he had personally notified researchers at scientific
meetings, but no TSE researcher contacted by UPI was aware of this."I was never
informed," said Laura Manuelidis, an expert on these diseases and section chief
of surgery in the neuropathology department at Yale University. She said the
first she had heard of the situation was in UPI's March 24 report. Manuelidis
also said she contacted Major, expressing interest in the specimens, but so far
has not received a response. "I sent a letter to (Major) on (March 25) about our
interest in these specimens, but he has not replied," she told UPI in an
e-mail.Neil Cashman, a TSE expert at the University of Toronto, who said he was
not aware the samples might be destroyed, has lobbied colleagues at the
University of British Columbia -- where Cashman is scheduled to move to this
summer -- to help draft a letter requesting the collection.The Memorial
Institute for Neurodegenerative Diseases Inc., a non-profit organization
consisting of more than 40 university and institute researchers from the United
States, Canada, the United Kingdom and France, requested the collection in
January, 2004. So far, the institute has not been informed of a decision by the
NIH.Asked if Major had told him whether the collection would be preserved, MIND
Executive Director Harry Peery said, "We have heard nothing further from Eugene
Major or anyone else at the NIH regarding the brain collection."
MORE FUNDING TO DR.Frank Bastian! The only funding he gets is from NIH, and
they are on the verge of shutting him down. give him a bigger grant. believe me,
all the answers to this agent are not answered yet, and many many humans and
animals have been exposed, with more to follow. There is not enough money being
funded/granted to the research of human/animal TSE compared to other diseases
and this will come back at us by many more due to incubation period and everyone
just ignoring it over the years, and there just might be more to this nightmare
than a prion.
=======================
Dr. Pierluigi Gambetti, who heads the National Prion Diseases Pathology
Surveillance Center at Case Western Reserve University in Ohio and works with
the Centers for Disease Control and Prevention to monitor all cases of CJD in
the United States. Dr. Gambetti studies the tissues to learn about the
formation, physical and chemical properties, and pathogenic mechanisms of prion
proteins, which are believed to be involved in the cause of CJD.
=======================
HOW CAN YOU monitor all cases of CJD when it is not reportable in every
state of all age groups? WITH all the animal TSEs in the USA for over 2 decades
rendered and fed back to each other for human and animal consumption, with TSE
in cattle that we know of in the USA and some others rendered without TSE test,
how can all sporadic CJD in the USA be sporadic? I hate that word. its just an
excuse or lie.
FINALLY, a kind thank you to Dr. Landis et al at NINDS, and there
'confirmation letter' that our loved ones brain and tissues samples will be
preserved and used for CJD research.ALSO, a kind tribute to the late Dr. Joe
Gibbs whom we all miss and respected so much. HE would have been very upset if
those brain and tissue samples would have been destroyed.
with kindest regards, I am sincerely,
Terry S. Singeltary SR. P.O. Box 42 Bacliff, Texas USA 77518
Groups seek to save NIH brain collection
By STEVE MITCHELL, Medical Correspondent | April 1, 2005 at 4:48 PM
WASHINGTON, April 1 (UPI) -- Scientists, consumer groups and
patient-advocates have embarked upon efforts -- including petitioning members of
Congress and seeking storage space at a Canadian university -- to prevent the
National Institutes of Health from destroying an irreplaceable collection of
human brains from patients afflicted with a condition similar to mad cow
disease.
As United Press International reported last week, the NIH has begun
shopping for a new home for its collection of brains, spinal fluid and other
tissues from hundreds of patients around the world who died from Creutzfeldt
Jakob disease -- an incurable, fatal, brain-wasting illness. The collection
dates back to 1963 and the consensus among scientists in this field is it is
invaluable for research and could provide insights that might aid in developing
diagnostic tests, treatments or cures for CJD.
NIH officials, however, maintain the remaining samples in the collection
-- stored in some 30 freezers by the National Institute for Neurological
Disorders and Stroke in Bethesda, Md. -- are of little value and may be disposed
of if researchers or institutions do not come forward to claim them.
Families of patients who died of CJD have reacted with outrage, concerned
that the effort mounted to collect the brains in the first place has been all
for naught. Several have contacted their respective members of Congress and
urged them to step in.
"The brains and brain tissue were sent to NIH in good faith for future
research and destroying them is an outrage," Terry Singeltary, a patient
advocate in Bacliff, Texas, wrote in a letter to Sen. Kay Bailey Hutchinson,
R-Texas, and several other members of the state's congressional delegation.
Singeltary's mother died of a type of CJD called Heidenhain variant in 1997.
Hutchinson's office did not return a call from UPI.
Eugene Major, who serves as acting director of the NINDS and is responsible
for the fate of the brain collection, did not return a call from UPI.
"The patients these brains were taken from suffered greatly before they
died of CJD," Heather Larson of Phoenix, whose mother succumbed to CJD last year
at the age of 56, wrote in a letter to Arizona Republican Sens. John McCain and
Jon Kyl, and Republican Rep. John Shadegg. "Their brains hold answers that can
save human lives. Destroying the brains at Bethesda would greatly hinder the
research being done to fight this disease and would cost many their
lives."
The offices of McCain and Kyl did not return UPI's calls.
"The ravages of this disease, and the toll it takes not only on its victims
but on family and loved ones, cannot easily be described to someone who has not
witnessed it personally," Patty Cook of Kansas City, Kan., wrote in a letter to
Kansas Republican Sens. Sam Brownback and Pat Roberts, and Democratic Rep.
Dennis Moore.
"I urge you to do whatever you can to ensure these brains are not
destroyed," added Cook, whose mother died of CJD in 1982.
Brownback's office did not return a call from UPI.
CJD belongs to a group of diseases -- called transmissible spongiform
encephalopathies or TSEs -- that includes mad cow disease, chronic wasting
disease in deer and elk, scrapie in sheep and several types of CJD in humans.
There is no cure for CJD and it typically results in death within a year after
the onset of symptoms.
Consumer groups also are concerned and are considering taking steps to
ensure the brain collection will be preserved.
"This is outrageous," Michael Hansen, a biologist and senior research
associate with Consumers Union in Yonkers, N.Y., told UPI. "Those brains are a
critical resource for CJD science and they must be at a research facility."
Hansen added that his late friend, Joe Gibbs, the former chief of NINDS's
Laboratory of Central Nervous System Studies, told him the brain of famed
choreographer George Balanchine, who died of CJD in 1983, resides in the
collection.
"How can we claim to be a scientific country if we're going to be throwing
away an irreplaceable repository of the first evidence of these diseases?" asked
Felicia Nestor, who serves as a consultant to Public Citizen.
There may be hope yet for the collection, however.
Neil Cashman, an expert on TSEs at the University of Toronto's Center for
Research in Neurodegenerative Diseases, told UPI he has been attempting to drum
up support for acquiring the collection with his colleagues at the University of
British Columbia in Vancouver -- where he plans to move this summer.
"I'm trying to organize support for an official letter from UBC to NIH to
request the collection," Cashman said.
The letter will probably go out in about a month, he said.
"The goal would be to make it a resource for the world and make the tissues
available to scientists who had a reasonable request," he added.
Singeltary said he has heard from at least one other prominent scientist in
this field who said they planned to contact the NIH and urge it to reconsider
the fate of the collection.
One brain in the collection, that of a French woman who died in 1971, may
help provide clues about the origins of variant CJD -- a condition similar to
CJD that humans can contract from eating beef products contaminated with the
mad-cow pathogen. The first recognized case of vCJD occurred in 1995 in the
United Kingdom, but an NIH scientist said he tested the French woman's brain in
2000 and found signs consistent with vCJD -- not CJD.
French researchers currently are re-examining specimens from the case to
determine if the woman was indeed infected with vCJD. If she was, it would
suggest the disease began infecting people more than 20 years earlier than
previously thought.
Cashman said the case underscores the value of the NIH brain
collection.
"There is information locked up in these freezers that will be lost forever
if this collection is destroyed," he said.

US scientist accused of selling tissue samples Deal said to earn $285,000
for vials that cost millions By Diedtra Henderson, Globe Staff | June 14,
2006
WASHINGTON -- A senior government scientist pocketed hundreds of thousands
of dollars as a drug company consultant in exchange for human tissue samples
that cost the federal government millions to acquire, congressional
investigators said yesterday .
The House Energy and Commerce Committee report, the culmination of a
one-year inquiry, was released hours before a two-day hearing began to explore
the government's practices for procuring human tissue samples. According to
congressional investigators, the National Institutes of Health's Dr. Trey
Sunderland agreed to collaborate with Pfizer Inc. , the world's largest drug
company. Sunderland, chief of the geriatric psychiatry branch of the National
Institute for Mental Health , sent Pfizer 3,200 tubes of spinal fluid and 388
tubes of plasma collected for Alzheimer's research.
The government spent $6.4 million to obtain the 3,500 samples that showed
how Alzheimer's disease progressed in 538 subjects.
Pfizer paid Sunderland $285,000 in consulting fees related to the samples,
investigators said. In total, Pfizer paid him more than $600,000 from 1998 to
2004 for outside consulting and speaking fees. Sunderland is scheduled to
testify today at the hearing.
``Contrary to the House committee report, Dr. Sunderland did not receive
any payments from Pfizer for human tissue samples," said Robert F. Muse, the
scientist's Washington, D.C., attorney. ``He acted properly, ethically, and
legally in his relationship with Pfizer."
Pfizer spokeswoman Kate Robins said the company had a transfer agreement
endorsed by the NIH that permitted Sunderland to send cerebrospinal fluid from
research participants with Alzheimer's, the participant's relatives who were at
higher risk of developing the neurological disease, and elderly adults with
normal Alzheimer's risk.
Sunderland's consulting role tapped his Alzheimer's disease expertise to
look for signals in the samples that could help identify and diagnose the
disease.
``The payments over a six-year period were reasonable and customary for an
expert of Dr. Sunderland's stature, and reflect the fair-market value of his
consulting services," Robins said.
The report said the tissue transfers, reported by a government
whistleblower, raised serious questions about how the government ensures its
scientists do not abuse their positions and about the agency's ability to track
the valuable samples.
``NIH tells us it has no centralized inventory system that could tell the
NIH director how many vials of tissues are in freezers at a particular
institute," said Representative Joe Barton , Republican of Texas and House
Energy and Commerce Committee chairman . ``It would really be a shame if we find
out that the National Institutes of Health has more control over its paper clips
and trash cans than it has over its human tissue samples."
John T. Burklow , a NIH spokesman, said the agency shares ``the committee's
concerns in regard to the ethical management of human tissue samples."
Sunderland's arrangement with the drug maker -- made without NIH knowledge,
according to Burklow -- occurred after the agency relaxed its ethics policy
covering scientists' outside activities and ended before the agency enacted more
stringent rules.
The NIH, pressured by Barton's committee, on Aug. 25 curbed outside
consulting deals between its scientists and pharmaceutical and biotechnology
companies.

NIH Statement Regarding House Hearing on Human Tissue Samples Attribution:
John Burklow, NIH spokesman
NIH’s position on ethics is clear: any conflict of interest resulting in an
individual personally profiting from official government research activities
cannot be tolerated. We are committed to maintaining the public’s trust in NIH
and its scientists as an unbiased source of biomedical research guidance and
advice. The case under consideration concerns events that began in 1998 — after
the NIH ethics rules concerning outside activities were relaxed — and that ended
before the new rules were put in place. NIH has previously referred this case to
the relevant authorities for appropriate action.
It is important to note that the specific consulting arrangements in
question, had they been known to NIH, would not have been approved under the
present or previous ethics regulations. Outside consulting connected to an NIH
employee’s official government duties has always been prohibited at NIH.
NIH has undertaken a comprehensive review of its activities and conflict of
interest policies in the last few years. As a result of that process, on August
25, 2005, NIH implemented comprehensive ethics rules that make it clear what NIH
scientists can and cannot do in regard to outside activities. These new rules
removed any ambiguity about what is allowed or not allowed. Here are two
important points:
Under new NIH regulations, all NIH employees are now prohibited from
engaging in outside employment with pharmaceutical companies and biotechnology
companies in their private capacities — period. Collaboration and partnership
with industry can nonetheless be very valuable in scientific pursuits and NIH
rules allow such activities, as long as they are undertaken through an
officially approved Cooperative Research and Development Agreement (CRADA).
Although we cannot discuss this particular case because it remains under
investigation, we can speak to the relevant issues that it raises.
Collaborations among scientists that involve human tissue samples are
common and essential for science. There are, however, stringent rules in place
to protect the participants who donated their samples, and to ensure that there
is full informed consent.
We share the Committee’s concerns in regard to the ethical management of
human tissue samples and the development of rigorous and uniform policies to
protect the public’s trust and interests, while advancing science to address
important public health problems. The thousands of scientists who work at NIH
have always been and remain committed to these principles.
The Office of the Director, the central office at NIH, is responsible for
setting policy for NIH, which includes 27 Institutes and Centers. This involves
planning, managing, and coordinating the programs and activities of all NIH
components. The Office of the Director also includes program offices which are
responsible for stimulating specific areas of research throughout NIH.
Additional information is available at http://www.nih.gov/icd/od/.
The National Institutes of Health (NIH) — The Nation's Medical Research
Agency — includes 27 Institutes and Centers and is a component of the U.S.
Department of Health and Human Services. It is the primary federal agency for
conducting and supporting basic, clinical and translational medical research,
and it investigates the causes, treatments, and cures for both common and rare
diseases. For more information about NIH and its programs, visit www.nih.gov.

Dietary exposure to bovine spongiform encephalopathy (BSE) contaminated
bovine tissues is considered as the origin of variant Creutzfeldt Jakob (vCJD)
disease in human. To date, BSE agent is the only recognized zoonotic prion.
Despite the variety of Transmissible Spongiform Encephalopathy (TSE) agents that
have been circulating for centuries in farmed ruminants there is no apparent
epidemiological link between exposure to ruminant products and the occurrence of
other form of TSE in human like sporadic Creutzfeldt Jakob Disease (sCJD).
However, the zoonotic potential of the diversity of circulating TSE agents has
never been systematically assessed. The major issue in experimental assessment
of TSEs zoonotic potential lies in the modeling of the ‘species barrier‘, the
biological phenomenon that limits TSE agents’ propagation from a species to
another. In the last decade, mice genetically engineered to express normal forms
of the human prion protein has proved essential in studying human prions
pathogenesis and modeling the capacity of TSEs to cross the human species
barrier.
To assess the zoonotic potential of prions circulating in farmed ruminants,
we study their transmission ability in transgenic mice expressing human PrPC
(HuPrP-Tg). Two lines of mice expressing different forms of the human PrPC
(129Met or 129Val) are used to determine the role of the Met129Val dimorphism in
susceptibility/resistance to the different agents.
These transmission experiments confirm the ability of BSE prions to
propagate in 129M- HuPrP-Tg mice and demonstrate that Met129 homozygotes may be
susceptible to BSE in sheep or goat to a greater degree than the BSE agent in
cattle and that these agents can convey molecular properties and
neuropathological indistinguishable from vCJD. However homozygous 129V mice are
resistant to all tested BSE derived prions independently of the originating
species suggesting a higher transmission barrier for 129V-PrP variant.
Transmission data also revealed that several scrapie prions propagate in
HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the
efficiency of transmission at primary passage was low, subsequent passages
resulted in a highly virulent prion disease in both Met129 and Val129 mice.
Transmission of the different scrapie isolates in these mice leads to the
emergence of prion strain phenotypes that showed similar characteristics to
those displayed by MM1 or VV2 sCJD prion. These results demonstrate that scrapie
prions have a zoonotic potential and raise new questions about the possible link
between animal and human prions.

2015. Transmission of scrapie prions to primate after an extended silent
incubation period. Scientific Reports. 5:11573.
Interpretive Summary: The transmissible spongiform encephalopathies (also
called prion diseases) are fatal neurodegenerative diseases that affect animals
and humans. The agent of prion diseases is a misfolded form of the prion protein
that is resistant to breakdown by the host cells. Since all mammals express
prion protein on the surface of various cells such as neurons, all mammals are,
in theory, capable of replicating prion diseases. One example of a prion
disease, bovine spongiform encephalopathy (BSE; also called mad cow disease),
has been shown to infect cattle, sheep, exotic undulates, cats, non-human
primates, and humans when the new host is exposed to feeds or foods contaminated
with the disease agent. The purpose of this study was to test whether non-human
primates (cynomologous macaque) are susceptible to the agent of sheep scrapie.
After an incubation period of approximately 10 years a macaque developed
progressive clinical signs suggestive of neurologic disease. Upon postmortem
examination and microscopic examination of tissues, there was a widespread
distribution of lesions consistent with a transmissible spongiform
encephalopathy. This information will have a scientific impact since it is the
first study that demonstrates the transmission of scrapie to a non-human primate
with a close genetic relationship to humans. This information is especially
useful to regulatory officials and those involved with risk assessment of the
potential transmission of animal prion diseases to humans. Technical Abstract:
Classical bovine spongiform encephalopathy (c-BSE) is an animal prion disease
that also causes variant Creutzfeldt-Jakob disease in humans. Over the past
decades, c-BSE's zoonotic potential has been the driving force in establishing
extensive protective measures for animal and human health.
*** In complement to the recent demonstration that humanized mice are
susceptible to scrapie, we report here the first observation of direct
transmission of a natural classical scrapie isolate to a macaque after a 10-year
incubation period. Neuropathologic examination revealed all of the features of a
prion disease: spongiform change, neuronal loss, and accumulation of PrPres
throughout the CNS.
*** This observation strengthens the questioning of the harmlessness of
scrapie to humans, at a time when protective measures for human and animal
health are being dismantled and reduced as c-BSE is considered controlled and
being eradicated.
*** Our results underscore the importance of precautionary and protective
measures and the necessity for long-term experimental transmission studies to
assess the zoonotic potential of other animal prion strains.

Sheep consumption: a possible source of spongiform encephalopathy in
humans.
Davanipour Z, Alter M, Sobel E, Callahan M.
A fatal spongiform encephalopathy of sheep and goats (scrapie) shares many
characteristics with Creutzfeldt-Jakob disease (CJD), a similar dementing
illness of humans. To investigate the possibility that CJD is acquired by
ingestion of contaminated sheep products, we collected information on
production, slaughtering practices, and marketing of sheep in Pennsylvania. The
study revealed that sheep were usually marketed before central nervous system
signs of scrapie are expected to appear; breeds known to be susceptible to the
disease were the most common breeds raised in the area; sheep were imported from
other states including those with a high frequency of scrapie; use of veterinary
services on the sheep farms investigated and, hence, opportunities to detect the
disease were limited; sheep producers in the area knew little about scrapie
despite the fact that the disease has been reported in the area, and animal
organs including sheep organs were sometimes included in processed food.
Therefore, it was concluded that in Pennsylvania there are some 'weak links'
through which scrapie-infected animals could contaminate human food, and that
consumption of these foods could perhaps account for spongiform encephalopathy
in humans. The weak links observed are probably not unique to Pennsylvania.

Prion diseases (PD) are the unique neurodegenerative proteinopathies
reputed to be transmissible under field conditions since decades. The
transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that
an animal PD might be zoonotic under appropriate conditions. Contrarily, in the
absence of obvious (epidemiological or experimental) elements supporting a
transmission or genetic predispositions, PD, like the other proteinopathies, are
reputed to occur spontaneously (atpical animal prion strains, sporadic CJD
summing 80% of human prion cases). Non-human primate models provided the first
evidences supporting the transmissibiity of human prion strains and the zoonotic
potential of BSE. Among them, cynomolgus macaques brought major information for
BSE risk assessment for human health (Chen, 2014), according to their
phylogenetic proximity to humans and extended lifetime. We used this model to
assess the zoonotic potential of other animal PD from bovine, ovine and cervid
origins even after very long silent incubation periods.
*** We recently observed the direct transmission of a natural classical
scrapie isolate to macaque after a 10-year silent incubation period,
***with features similar to some reported for human cases of sporadic CJD,
albeit requiring fourfold long incubation than BSE. Scrapie, as recently evoked
in humanized mice (Cassard, 2014),

***thus questioning the origin of human sporadic cases. We will present an

Abstract
Although Bovine Spongiform Encephalopathy (BSE) is the cause of variant
Creutzfeldt Jakob disease (vCJD) in humans, the zoonotic potential of scrapie
prions remains unknown. Mice genetically engineered to overexpress the human
prion protein (tgHu) have emerged as highly relevant models for gauging the
capacity of prions to transmit to humans. These models can propagate human
prions without any apparent transmission barrier and have been used used to
confirm the zoonotic ability of BSE. Here we show that a panel of sheep scrapie
prions transmit to several tgHu mice models with an efficiency comparable to
that of cattle BSE.
***The serial transmission of different scrapie isolates in these mice led
to the propagation of prions that are phenotypically identical to those causing
sporadic CJD (sCJD) in humans.
***These results demonstrate that scrapie prions have a zoonotic potential
and raise new questions about the possible link between animal and human prions.

why do we not want to do TSE transmission studies on chimpanzees $

create alarm in some circles even if the result could not be interpreted for
man. I have a view that all these agents could be transmitted provided a large
enough dose by appropriate routes was given and the animals kept long enough.
Until the mechanisms of the species barrier are more clearly understood it might
be best to retain that hypothesis.

Oral transmission of kuru, Creutzfeldt-Jakob disease, and scrapie to
nonhuman primates.
Gibbs CJ Jr, Amyx HL, Bacote A, Masters CL, Gajdusek DC.
Kuru and Creutzfeldt-Jakob disease of humans and scrapie disease of sheep
and goats were transmitted to squirrel monkeys (Saimiri sciureus) that were
exposed to the infectious agents only by their nonforced consumption of known
infectious tissues. The asymptomatic incubation period in the one monkey exposed
to the virus of kuru was 36 months; that in the two monkeys exposed to the virus
of Creutzfeldt-Jakob disease was 23 and 27 months, respectively; and that in the
two monkeys exposed to the virus of scrapie was 25 and 32 months, respectively.
Careful physical examination of the buccal cavities of all of the monkeys failed
to reveal signs or oral lesions. One additional monkey similarly exposed to kuru
has remained asymptomatic during the 39 months that it has been under
observation.
snip...
The successful transmission of kuru, Creutzfeldt-Jakob disease, and scrapie
by natural feeding to squirrel monkeys that we have reported provides further
grounds for concern that scrapie-infected meat may occasionally give rise in
humans to Creutzfeldt-Jakob disease.
PMID: 6997404

Recently the question has again been brought up as to whether scrapie is
transmissible to man. This has followed reports that the disease has been
transmitted to primates. One particularly lurid speculation (Gajdusek 1977)
conjectures that the agents of scrapie, kuru, Creutzfeldt-Jakob disease and
transmissible encephalopathy of mink are varieties of a single "virus". The U.S.
Department of Agriculture concluded that it could "no longer justify or permit
scrapie-blood line and scrapie-exposed sheep and goats to be processed for human
or animal food at slaughter or rendering plants" (ARC 84/77)" The problem is
emphasised by the finding that some strains of scrapie produce lesions identical
to the once which characterise the human dementias"
Whether true or not. the hypothesis that these agents might be
transmissible to man raises two considerations. First, the safety of laboratory
personnel requires prompt attention. Second, action such as the "scorched meat"
policy of USDA makes the solution of the acrapie problem urgent if the sheep
industry is not to suffer grievously.

Chronic wasting disease (CWD) is a widespread and highly transmissible
prion disease in free-ranging and captive cervid species in North America. The
zoonotic potential of CWD prions is a serious public health concern, but the
susceptibility of human CNS and peripheral organs to CWD prions remains largely
unresolved. We reported earlier that peripheral and CNS infections were detected
in transgenic mice expressing human PrP129M or PrP129V. Here we will present an
update on this project, including evidence for strain dependence and influence
of cervid PrP polymorphisms on CWD zoonosis as well as the characteristics of
experimental human CWD prions.

Cervid to human prion transmission
Kong, Qingzhong
Case Western Reserve University, Cleveland, OH, United States
Abstract
Prion disease is transmissible and invariably fatal. Chronic wasting
disease (CWD) is the prion disease affecting deer, elk and moose, and it is a
widespread and expanding epidemic affecting 22 US States and 2 Canadian
provinces so far. CWD poses the most serious zoonotic prion transmission risks
in North America because of huge venison consumption (>6 million deer/elk
hunted and consumed annually in the USA alone), significant prion infectivity in
muscles and other tissues/fluids from CWD-affected cervids, and usually high
levels of individual exposure to CWD resulting from consumption of the affected
animal among often just family and friends. However, we still do not know
whether CWD prions can infect humans in the brain or peripheral tissues or
whether clinical/asymptomatic CWD zoonosis has already occurred, and we have no
essays to reliably detect CWD infection in humans. We hypothesize that:
(1) The classic CWD prion strain can infect humans at low levels in the
brain and peripheral lymphoid tissues;
(2) The cervid-to-human transmission barrier is dependent on the cervid
prion strain and influenced by the host (human) prion protein (PrP) primary
sequence;
(3) Reliable essays can be established to detect CWD infection in
humans;and
(4) CWD transmission to humans has already occurred. We will test these
hypotheses in 4 Aims using transgenic (Tg) mouse models and complementary in
vitro approaches.
Aim 1 will prove that the classical CWD strain may infect humans in brain
or peripheral lymphoid tissues at low levels by conducting systemic bioassays in
a set of "humanized" Tg mouse lines expressing common human PrP variants using a
number of CWD isolates at varying doses and routes. Experimental "human CWD"
samples will also be generated for Aim 3.
Aim 2 will test the hypothesis that the cervid-to-human prion transmission
barrier is dependent on prion strain and influenced by the host (human) PrP
sequence by examining and comparing the transmission efficiency and phenotypes
of several atypical/unusual CWD isolates/strains as well as a few prion strains
from other species that have adapted to cervid PrP sequence, utilizing the same
panel of humanized Tg mouse lines as in Aim 1.
Aim 3 will establish reliable essays for detection and surveillance of CWD
infection in humans by examining in details the clinical, pathological,
biochemical and in vitro seeding properties of existing and future experimental
"human CWD" samples generated from Aims 1-2 and compare them with those of
common sporadic human Creutzfeldt-Jakob disease (sCJD) prions.
Aim 4 will attempt to detect clinical CWD-affected human cases by examining
a significant number of brain samples from prion-affected human subjects in the
USA and Canada who have consumed venison from CWD-endemic areas utilizing the
criteria and essays established in Aim 3. The findings from this proposal will
greatly advance our understandings on the potential and characteristics of
cervid prion transmission in humans, establish reliable essays for CWD zoonosis
and potentially discover the first case(s) of CWD infection in humans.
Public Health Relevance There are significant and increasing human exposure
to cervid prions because chronic wasting disease (CWD, a widespread and highly
infectious prion disease among deer and elk in North America) continues
spreading and consumption of venison remains popular, but our understanding on
cervid-to-human prion transmission is still very limited, raising public health
concerns. This proposal aims to define the zoonotic risks of cervid prions and
set up and apply essays to detect CWD zoonosis using mouse models and in vitro
methods. The findings will greatly expand our knowledge on the potentials and
characteristics of cervid prion transmission in humans, establish reliable
essays for such infections and may discover the first case(s) of CWD infection
in humans.

Key Molecular Mechanisms of TSEs
Zabel, Mark D.
Colorado State University-Fort Collins, Fort Collins, CO, United States
Abstract Prion diseases, or transmissible spongiform encephalopathies (TSEs),
are fatal neurodegenerative diseases affecting humans, cervids, bovids, and
ovids. The absolute requirement of PrPC expression to generate prion diseases
and the lack of instructional nucleic acid define prions as unique infectious
agents. Prions exhibit species-specific tropism, inferring that unique prion
strains exist that preferentially infct certain host species and confront
transmission barriers to heterologous host species. However, transmission
barriers are not absolute. Scientific consensus agrees that the sheep TSE
scrapie probably breached the transmission barrier to cattle causing bovine
spongiform encephalopathy that subsequently breached the human transmission
barrier and likely caused several hundred deaths by a new-variant form of the
human TSE Creutzfeldt-Jakob disease in the UK and Europe. The impact to human
health, emotion and economies can still be felt in areas like farming, blood and
organ donations and the threat of a latent TSE epidemic. This precedent raises
the real possibility of other TSEs, like chronic wasting disease of cervids,
overcoming similar human transmission barriers. A groundbreaking discovery made
last year revealed that mice infected with heterologous prion strains facing
significant transmission barriers replicated prions far more readily in spleens
than brains6. Furthermore, these splenic prions exhibited weakened transmission
barriers and expanded host ranges compared to neurogenic prions. These data
question conventional wisdom of avoiding neural tissue to avoid prion
xenotransmission, when more promiscuous prions may lurk in extraneural tissues.
Data derived from work previously funded by NIH demonstrate that Complement
receptors CD21/35 bind prions and high density PrPC and differentially impact
prion disease depending on the prion isolate or strain used. Recent advances in
live animal and whole organ imaging have led us to generate preliminary data to
support novel, innovative approaches to assessing prion capture and transport.
We plan to test our unifying hypothesis for this proposal that CD21/35 control
the processes of peripheral prion capture, transport, strain selection and
xenotransmission in the following specific aims. 1. Assess the role of CD21/35
in splenic prion strain selection and host range expansion. 2. Determine whether
CD21/35 and C1q differentially bind distinct prion strains 3. Monitor the
effects of CD21/35 on prion trafficking in real time and space 4. Assess the
role of CD21/35 in incunabular prion trafficking
Public Health Relevance Transmissible spongiform encephalopathies, or prion
diseases, are devastating illnesses that greatly impact public health,
agriculture and wildlife in North America and around the world. The impact to
human health, emotion and economies can still be felt in areas like farming,
blood and organ donations and the threat of a latent TSE epidemic. This
precedent raises the real possibility of other TSEs, like chronic wasting
disease (CWD) of cervids, overcoming similar human transmission barriers. Early
this year Canada reported its first case of BSE in over a decade audits first
case of CWD in farmed elk in three years, underscoring the need for continued
vigilance and research. Identifying mechanisms of transmission and zoonoses
remains an extremely important and intense area of research that will benefit
human and other animal populations.

PMCA Detection of CWD Infection in Cervid and Non-Cervid Species
Hoover, Edward Arthur
Colorado State University-Fort Collins, Fort Collins, CO, United States
Abstract Chronic wasting disease (CWD) of deer and elk is an emerging highly
transmissible prion disease now recognized in 18 States, 2 Canadian provinces,
and Korea. We have shown that Infected deer harbor and shed high levels of
infectious prions in saliva, blood, urine, and feces, and in the tissues
generating those body fluids and excreta, thereby leading to facile transmission
by direct contact and environmental contamination. We have also shown that CWD
can infect some non-cervid species, thus the potential risk CWD represents to
domestic animal species and to humans remains unknown. Whether prions borne in
blood, saliva, nasal fluids, milk, or excreta are generated or modified in the
proximate peripheral tissue sites, may differ in subtle ways from those
generated in brain, or may be adapted for mucosal infection remain open
questions. The increasing parallels in the pathogenesis between prion diseases
and human neurodegenerative conditions, such as Alzheimer's and Parkinson's
diseases, add relevance to CWD as a transmissible protein misfolding disease.
The overall goal of this work is to elucidate the process of CWD prion
transmission from mucosal secretory and excretory tissue sites by addressing
these questions: (a) What are the kinetics and magnitude of CWD prion shedding
post-exposure? (b) Are excreted prions biochemically distinct, or not, from
those in the CNS? (c) Are peripheral epithelial or CNS tissues, or both, the
source of excreted prions? and (d) Are excreted prions adapted for horizontal
transmission via natural/trans-mucosal routes? The specific aims of this
proposal are: (1) To determine the onset and consistency of CWD prion shedding
in deer and cervidized mice; (2); To compare the biochemical and biophysical
properties of excretory vs. CNS prions; (3) To determine the capacity of
peripheral tissues to support replication of CWD prions; (4) To determine the
protease- sensitive infectious fraction of excreted vs. CNS prions; and (5) To
compare the mucosal infectivity of excretory vs. CNS prions. Understanding the
mechanisms that enable efficient prion dissemination and shedding will help
elucidate how horizontally transmissible prions evolve and succeed, and is the
basis of this proposal. Understanding how infectious misfolded proteins (prions)
are generated, trafficked, shed, and transmitted will aid in preventing,
treating, and managing the risks associated with these agents and the diseases
they cause.
Public Health Relevance Chronic wasting disease (CWD) of deer and elk is an
emergent highly transmissible prion disease now recognized throughout the USA as
well as in Canada and Korea. We have shown that infected deer harbor and shed
high levels of infectious prions in saliva, blood, urine, and feces thereby
leading to transmission by direct contact and environmental contamination. In
that our studies have also shown that CWD can infect some non-cervid species,
the potential risk CWD may represents to domestic animal species and humans
remains unknown. The increasing parallels in the development of major human
neurodegenerative conditions, such as Alzheimer's and Parkinson's diseases, and
prion diseases add relevance to CWD as a model of a transmissible protein
misfolding disease. Understanding how infectious misfolded proteins (prions) are
generated and transmitted will aid in interrupting, treating, and managing the
risks associated with these agents and the diseases they cause.

*** These results would seem to suggest that CWD does indeed have zoonotic
potential, at least as judged by the compatibility of CWD prions and their human
PrPC target. Furthermore, extrapolation from this simple in vitro assay suggests
that if zoonotic CWD occurred, it would most likely effect those of the PRNP

the most common subtype of sCJD (MM1).***

disease, namely sCJD of the MM1 subtype.
*** These results would seem to suggest that CWD does indeed have zoonotic
potential, at least as judged by the compatibility of CWD prions and their human
PrPC target. Furthermore, extrapolation from this simple in vitro assay suggests
that if zoonotic CWD occurred, it would most likely effect those of the PRNP
codon 129-MM genotype and that the PrPres type would be similar to that found in
the most common subtype of sCJD (MM1).***
*** The potential impact of prion diseases on human health was greatly
magnified by the recognition that interspecies transfer of BSE to humans by beef
ingestion resulted in vCJD. While changes in animal feed constituents and
slaughter practices appear to have curtailed vCJD, there is concern that CWD of
free-ranging deer and elk in the U.S. might also cross the species barrier.
Thus, consuming venison could be a source of human prion disease. Whether BSE
and CWD represent interspecies scrapie transfer or are newly arisen prion
diseases is unknown. Therefore, the possibility of transmission of prion disease
through other food animals cannot be ruled out. There is evidence that vCJD can
be transmitted through blood transfusion. There is likely a pool of unknown size
of asymptomatic individuals infected with vCJD, and there may be asymptomatic
individuals infected with the CWD equivalent. These circumstances represent a
potential threat to blood, blood products, and plasma supplies.
***********CJD REPORT 1994 increased risk for consumption of veal and
venison and lamb***********
CREUTZFELDT JAKOB DISEASE SURVEILLANCE IN THE UNITED KINGDOM THIRD ANNUAL
REPORT AUGUST 1994
Consumption of venison and veal was much less widespread among both cases
and controls. For both of these meats there was evidence of a trend with
increasing frequency of consumption being associated with increasing risk of
CJD. (not nvCJD, but sporadic CJD...tss)
These associations were largely unchanged when attention was restricted to
pairs with data obtained from relatives. ...
Table 9 presents the results of an analysis of these data.
There is STRONG evidence of an association between ‘’regular’’ veal eating
and risk of CJD (p = .0.01).
Individuals reported to eat veal on average at least once a year appear to
be at 13 TIMES THE RISK of individuals who have never eaten veal.
There is, however, a very wide confidence interval around this estimate.
There is no strong evidence that eating veal less than once per year is
associated with increased risk of CJD (p = 0.51).
The association between venison eating and risk of CJD shows similar
pattern, with regular venison eating associated with a 9 FOLD INCREASE IN RISK
OF CJD (p = 0.04).
There is some evidence that risk of CJD INCREASES WITH INCREASING FREQUENCY
OF LAMB EATING (p = 0.02).
The evidence for such an association between beef eating and CJD is weaker
(p = 0.14). When only controls for whom a relative was interviewed are included,
this evidence becomes a little STRONGER (p = 0.08).
snip...
It was found that when veal was included in the model with another
exposure, the association between veal and CJD remained statistically
significant (p = < 0.05 for all exposures), while the other exposures ceased
to be statistically significant (p = > 0.05).
snip...
In conclusion, an analysis of dietary histories revealed statistical
associations between various meats/animal products and INCREASED RISK OF CJD.
When some account was taken of possible confounding, the association between
VEAL EATING AND RISK OF CJD EMERGED AS THE STRONGEST OF THESE ASSOCIATIONS
STATISTICALLY. ...
snip...
In the study in the USA, a range of foodstuffs were associated with an
increased risk of CJD, including liver consumption which was associated with an
apparent SIX-FOLD INCREASE IN THE RISK OF CJD. By comparing the data from 3
studies in relation to this particular dietary factor, the risk of liver
consumption became non-significant with an odds ratio of 1.2 (PERSONAL
COMMUNICATION, PROFESSOR A. HOFMAN. ERASMUS UNIVERSITY, ROTTERDAM). (???...TSS)

Dear Mr Elmhirst,
CREUTZFELDT-JAKOB DISEASE (CJD) SURVEILLANCE UNIT REPORT
Thank you for your recent letter concerning the publication of the third
annual report from the CJD Surveillance Unit. I am sorry that you are
dissatisfied with the way in which this report was published.
The Surveillance Unit is a completely independant outside body and the
Department of Health is committed to publishing their reports as soon as they
become available. In the circumstances it is not the practice to circulate the
report for comment since the findings of the report would not be amended. In
future we can ensure that the British Deer Farmers Association receives a copy
of the report in advance of publication.
The Chief Medical Officer has undertaken to keep the public fully informed
of the results of any research in respect of CJD. This report was entirely the
work of the unit and was produced completely independantly of the the
Department.
The statistical results reqarding the consumption of venison was put into
perspective in the body of the report and was not mentioned at all in the press
release. Media attention regarding this report was low key but gave a realistic
presentation of the statistical findings of the Unit. This approach to
publication was successful in that consumption of venison was highlighted only
once by the media ie. in the News at one television proqramme.
I believe that a further statement about the report, or indeed statistical
links between CJD and consumption of venison, would increase, and quite possibly
give damaging credence, to the whole issue. From the low key media reports of
which I am aware it seems unlikely that venison consumption will suffer
adversely, if at all.

BSE prions propagate as either variant CJD-like or sporadic CJD-like prion
strains in transgenic mice expressing human prion protein
*** Surprisingly, however, BSE transmission to these transgenic mice, in
addition to producing a vCJD-like phenotype, can also result in a distinct
molecular phenotype that is indistinguishable from that of sporadic CJD with
PrPSc type 2.
These data suggest that more than one BSEderived prion strain might infect
humans;
***it is therefore possible that some patients with a phenotype consistent
with sporadic CJD may have a disease arising from BSE exposure.
snip...
These studies further strengthen the evidence that vCJD is caused by a
BSE-like prion strain.
Also, remarkably, the key neuropathological hallmark of vCJD, the presence
of abundant florid PrP plaques, can be recapitulated on BSE or vCJD transmission
to these mice.
***However, the most surprising aspect of the studies was the finding that
an alternate pattern of disease can be induced in 129MM Tg35 mice from primary
transmission of BSE, with a molecular phenotype indistinguishable from that of a
subtype of sporadic CJD. This finding has important potential implications as it
raises the possibility that some humans infected with BSE prions may develop a
clinical disease indistinguishable from classical CJD associated with type 2
PrPSc. This is, in our experience, the commonest molecular sub-type of sporadic
CJD. In this regard, it is of interest that the reported incidence of sporadic
CJD has risen in the UK since the 1970s (Cousens et al., 1997)...

Dear Terry,
I have been asked by Professor Collinge to respond to your request. I am a
Senior Scientist in the MRC Prion Unit and the lead author on the paper. I have
attached a pdf copy of the paper for your attention.
Thank you for your interest in the paper.
In respect of your first question, the simple answer is, ***yes. As you
will find in the paper, we have managed to associate the alternate phenotype to
type 2 PrPSc, the commonest sporadic CJD. It is too early to be able to claim
any further sub-classification in respect of Heidenhain variant CJD or Vicky
Rimmer's version. It will take further studies, which are on-going, to establish
if there are sub-types to our initial finding which we are now reporting. The
main point of the paper is that, as well as leading to the expected new variant
CJD phenotype, BSE transmission to the 129-methionine genotype can lead to an
alternate phenotype which is indistinguishable from type 2 PrPSc.
I hope reading the paper will enlighten you more on the subject. If I can
be of any further assistance please to not hesitate to ask. Best wishes.

Seven main threats for the future linked to prions
First threat
The TSE road map defining the evolution of European policy for protection
against prion diseases is based on a certain numbers of hypotheses some of which
may turn out to be erroneous. In particular, a form of BSE (called atypical
Bovine Spongiform Encephalopathy), recently identified by systematic testing in
aged cattle without clinical signs, may be the origin of classical BSE and thus
potentially constitute a reservoir, which may be impossible to eradicate if a
sporadic origin is confirmed.
***Also, a link is suspected between atypical BSE and some apparently
sporadic cases of Creutzfeldt-Jakob disease in humans. These atypical BSE cases
constitute an unforeseen first threat that could sharply modify the European
approach to prion diseases.
Second threat

EFSA and the European Centre for Disease Prevention and Control (ECDC)
recently delivered a scientific opinion on any possible epidemiological or
molecular association between TSEs in animals and humans (EFSA Panel on
Biological Hazards (BIOHAZ) and ECDC, 2011). This opinion confirmed Classical
BSE prions as the only TSE agents demonstrated to be zoonotic so far
*** but the possibility that a small proportion of human cases so far
classified as "sporadic" CJD are of zoonotic origin could not be excluded.
Moreover, transmission experiments to non-human primates suggest that some TSE
agents in addition to Classical BSE prions in cattle (namely L-type Atypical
BSE, Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic
wasting disease (CWD) agents) might have zoonotic potential.

having such an excess over the incidence of CJD for the population as a whole.
No cases of CJD have been reported amount veterinarians exposed to BSE. Four
people in the meat industry (butchers, abattoirs, rendering plants, etc) have
been reported to have vCJD.386 The present evidence has been accepted by some as
reassuring in that such occupations may not pose as serious a risk as might have
been expected.

Over a 5 year period, which is the time period on which the advice from
Professor Smith and Dr. Gore was based, and assuming a population of 120,000
dairy farm workers, and an annual incidence of 1 per million cases of CJD in the
general population, a DAIRY FARM WORKER IS 5 TIMES MORE LIKELY THAN an
individual in the general population to develop CJD. Using the actual current
annual incidence of CJD in the UK of 0.7 per million, this figure becomes 7.5
TIMES.
3. You will recall that the advice provided by Professor Smith in 1993 and
by Dr. Gore this month used the sub-population of dairy farm workers who had had
a case of BSE on their farms - 63,000, which is approximately half the number of
dairy farm workers - as a denominator. If the above sums are repeated using this
denominator population, taking an annual incidence in the general population of
1 per million the observed rate in this sub-population is 10 TIMES, and taking
an annual incidence of 0.7 per million, IT IS 15 TIMES (THE ''WORST CASE''

One reason for this was the _inaccuracy_ in coding of cases correctly
certified as CJD Coding is carried out by staff who are not medically qualified
and it is not surprising that coding errors occur in the processing of large
numbers of certificates. In 1982, 12,000 certificates per week were processed at
the office of population censuses and surveys by 15 coders and 6 checkers
(Alderson et al., 1983). The occurrence of both inter- and intra-observer coding
errors has been described (Curb et al., 1983) and the _inaccuracies_ of BOTH
certification and coding discovered in this study _support_ the introduction of

Cases of CJD may be identified from death certificates, but this alone is

diagnosis; in the Oxford study death certificates were obtained on a series of
known confirmed cases and CJD was mentioned in only 66% of certificates. In
another series of 175 certified cases, 42 patients were judged not to have
suffered from CJD after examination of case notes (7)...

2001 Deepthroat to Singeltary
The most frightening thing I have read all day is the report of Gambetti's
finding of a new strain of sporadic cjd in young people.........Dear God, what
in the name of all that is holy is that!!! If the US has different strains of
scrapie.....why???? than the UK...then would the same mechanisms that make
different strains of scrapie here make different strains of BSE...if the
patterns are different in sheep and mice for scrapie.....could not the BSE be
different in the cattle, in the mink, in the humans.......I really think the
slides or tissues and everything from these young people with the new strain of
sporadic cjd should be put up to be analyzed by many, many experts in
cjd........bse.....scrapie Scrape the damn slide and put it into
mice.....wait.....chop up the mouse brain and and spinal cord........put into
some more mice.....dammit amplify the thing and start the damned
research.....This is NOT rocket science...we need to use what we know and get
off our butts and move....the whining about how long everything takes.....well
it takes a whole lot longer if you whine for a year and then start the
research!!! Not sure where I read this but it was a recent press release or
something like that: I thought I would fall out of my chair when I read about
how there was no worry about infectivity from a histopath slide or tissues
because they are preserved in formic acid, or formalin or formaldehyde.....for
God's sake........ Ask any pathologist in the UK what the brain tissues in the
formalin looks like after a year.......it is a big fat sponge...the agent
continues to eat the brain ......you can't make slides anymore because the agent
has never stopped........and the old slides that are stained with Hemolysin and
Eosin......they get holier and holier and degenerate and continue...what you
looked at 6 months ago is not there........Gambetti better be photographing
every damned thing he is looking at.....
Okay, you need to know. You don't need to pass it on as nothing will come
of it and there is not a damned thing anyone can do about it. Don't even hint at
it as it will be denied and laughed at.......... USDA is gonna do as little as
possible until there is actually a human case in the USA of the nvcjd........if
you want to move this thing along and shake the earth....then we gotta get the
victims families to make sure whoever is doing the autopsy is credible,
trustworthy, and a saint with the courage of Joan of Arc........I am not
kidding!!!! so, unless we get a human death from EXACTLY the same form with
EXACTLY the same histopath lesions as seen in the UK nvcjd........forget any
action........it is ALL gonna be sporadic!!!
And, if there is a case.......there is gonna be every effort to link it to
international travel, international food, etc. etc. etc. etc. etc. They will go
so far as to find out if a sex partner had ever traveled to the UK/europe, etc.
etc. .... It is gonna be a long, lonely, dangerous twisted journey to the truth.
They have all the cards, all the money, and are willing to threaten and carry
out those threats....and this may be their biggest downfall...
Thanks as always for your help.
(Recently had a very startling revelation from a rather senior person in
government here..........knocked me out of my chair........you must keep
pushing. If I was a power person....I would be demanding that there be a least a
million bovine tested as soon as possible and agressively seeking this disease.
The big players are coming out of the woodwork as there is money to be made!!!
In short: "FIRE AT WILL"!!! for the very dumb....who's "will"! "Will be the
burden to bare if there is any coverup!"
again it was said years ago and it should be taken seriously....BSE will
NEVER be found in the US! As for the BSE conference call...I think you did a
great service to freedom of information and making some people feign
integrity...I find it scary to see that most of the "experts" are employed by
the federal government or are supported on the "teat" of federal funds. A scary
picture! I hope there is a confidential panel organized by the new government to
really investigate this thing.
You need to watch your back........but keep picking at them.......like a
buzzard to the bone...you just may get to the truth!!! (You probably have more
support than you know. Too many people are afraid to show you or let anyone else
know. I have heard a few things myself... you ask the questions that everyone
else is too afraid to ask.)

APHIS [Docket No. APHIS-2016-0029] Secretary's Advisory Committee on Animal
Health; Meeting May 2, 2016, and June 16, 2016 Singeltary Submission
Evidence That Transmissible Mink Encephalopathy Results from Feeding
Infected Cattle
Over the next 8-10 weeks, approximately 40% of all the adult mink on the
farm died from TME.

animals in the USA - APRIL-MAY 1989 - G A H Wells
3. Prof. A. Robertson gave a brief account of BSE. The US approach was to
accord it a very low profile indeed. Dr. A Thiermann showed the picture in the
''Independent'' with cattle being incinerated and thought this was a fanatical
incident to be avoided in the US at all costs. ...
”The occurrence of CWD must be viewed against the contest of the locations
in which it occurred. It was an incidental and unwelcome complication of the
respective wildlife research programmes. Despite it’s subsequent recognition as
a new disease of cervids, therefore justifying direct investigation, no specific
research funding was forthcoming. The USDA veiwed it as a wildlife problem and
consequently not their province!” ...page 26.
