OR-10: Variably protease-sensitive prionopathy is transmissible in bank voles




Romolo Nonno,1 Michele Di Bari,1 Laura Pirisinu,1 Claudia D’Agostino,1 Stefano Marcon,1 Geraldina Riccardi,1 Gabriele Vaccari,1 Piero Parchi,2 Wenquan Zou,3 Pierluigi Gambetti,3 Umberto Agrimi1 1Istituto Superiore di Sanità; Rome, Italy; 2Dipartimento di Scienze Neurologiche, Università di Bologna; Bologna, Italy; 3Case Western Reserve University; Cleveland, OH USA



Background. Variably protease-sensitive prionopathy (VPSPr) is a recently described “sporadic”neurodegenerative disease involving prion protein aggregation, which has clinical similarities with non-Alzheimer dementias, such as fronto-temporal dementia. Currently, 30 cases of VPSPr have been reported in Europe and USA, of which 19 cases were homozygous for valine at codon 129 of the prion protein (VV), 8 were MV and 3 were MM. A distinctive feature of VPSPr is the electrophoretic pattern of PrPSc after digestion with proteinase K (PK). After PK-treatment, PrP from VPSPr forms a ladder-like electrophoretic pattern similar to that described in GSS cases. The clinical and pathological features of VPSPr raised the question of the correct classification of VPSPr among prion diseases or other forms of neurodegenerative disorders. Here we report preliminary data on the transmissibility and pathological features of VPSPr cases in bank voles.



Materials and Methods. Seven VPSPr cases were inoculated in two genetic lines of bank voles, carrying either methionine or isoleucine at codon 109 of the prion protein (named BvM109 and BvI109, respectively). Among the VPSPr cases selected, 2 were VV at PrP codon 129, 3 were MV and 2 were MM. Clinical diagnosis in voles was confirmed by brain pathological assessment and western blot for PK-resistant PrPSc (PrPres) with mAbs SAF32, SAF84, 12B2 and 9A2.



Results. To date, 2 VPSPr cases (1 MV and 1 MM) gave positive transmission in BvM109. Overall, 3 voles were positive with survival time between 290 and 588 d post inoculation (d.p.i.). All positive voles accumulated PrPres in the form of the typical PrP27–30, which was indistinguishable to that previously observed in BvM109 inoculated with sCJDMM1 cases.



In BvI109, 3 VPSPr cases (2 VV and 1 MM) showed positive transmission until now. Overall, 5 voles were positive with survival time between 281 and 596 d.p.i.. In contrast to what observed in BvM109, all BvI109 showed a GSS-like PrPSc electrophoretic pattern, characterized by low molecular weight PrPres. These PrPres fragments were positive with mAb 9A2 and 12B2, while being negative with SAF32 and SAF84, suggesting that they are cleaved at both the C-terminus and the N-terminus. Second passages are in progress from these first successful transmissions.



Conclusions. Preliminary results from transmission studies in bank voles strongly support the notion that VPSPr is a transmissible prion disease. Interestingly, VPSPr undergoes divergent evolution in the two genetic lines of voles, with sCJD-like features in BvM109 and GSS-like properties in BvI109.



The discovery of previously unrecognized prion diseases in both humans and animals (i.e., Nor98 in small ruminants) demonstrates that the range of prion diseases might be wider than expected and raises crucial questions about the epidemiology and strain properties of these new forms. We are investigating this latter issue by molecular and biological comparison of VPSPr, GSS and Nor98.

I believe it was Gambetti et al that coined this term sporadic FFI, from some conspicuous sub-type of sporadic CJD possibly? seems they could not tie it to a true FFI by diagnostic standards to date, so it was then termed a sFFI, confusing matters even worse. ...

THIS seems to raise more questions than answers, confusing the TSEs even worse.

WHAT is sporadic CJD, and how many sub-types and atypical strains, phenotypes etc. will there be, arising from nothing. a spontaneous happening of sorts???

i think not. ...tss

BSE-The Untold Story - joe gibbs and singeltary 1999 – 2009



http://madcowusda.blogspot.com/2009/08/bse-untold-story-joe-gibbs-and.html





====================================


The familial mutations, Gajdusek proposed, lowered the barrier to such accidental conversion. "Thus," he wrote in 1996, "with these mutations, this ordinarily rare event becomes a ... dominant inherited trait." But Weissmann's qualification still remained to be refuted: the mutations might simply allow easier entry to a lurking virus. ...page 202 Deadly Feast


===================================



something to think about for sure.



but i interpret this as (1st not the gold standard, just my opinion;-), as because of certain gene mutations, one or a family, would be more susceptible to the many different strains of TSE, and the many different proven routes and sources, (which will cause different symptoms, different incubation periods from onset of clinical symptoms to death, different parts of the brain infected, etc.). in other words, it's NOT the gene mutation that CAUSES the disease, but the fact that it makes you more SUSCEPTIBLE, to the TSEs from the surrounding environment, and PLUS accumulation, i think this plays a critical role. maybe there is a one dose scenario, but i think there is more of the 'accumulators' that go clinical, than the 'one dose'. and what is the threshold to sub-clinical to clinical ?

anyway, just pondering out loud here.

also, for anyone interested, there are some studies with links to follow here ;

Emergency Bovine Spongiform Encephalopathy Response Plan Summary and BSE Red Book

Date: February 14, 2000 at 8:56 am PST

WHERE did we go wrong $$$


http://madcowtesting.blogspot.com/2009/07/us-emergency-bovine-spongiform.html





LET'S take a closer look at this new prionpathy or prionopathy, and then let's look at the g-h-BSEalabama mad cow. This new prionopathy in humans? the genetic makeup is IDENTICAL to the g-h-BSEalabama mad cow, the only _documented_ mad cow in the world to date like this, ......wait, it get's better. this new prionpathy is killing young and old humans, with LONG DURATION from onset of symptoms to death, and the symptoms are very similar to nvCJD victims, OH, and the plaques are very similar in some cases too, bbbut, it's not related to the g-h-BSEalabama cow, WAIT NOW, it gets even better, the new human prionpathy that they claim is a genetic TSE, has no relation to any gene mutation in that family. daaa, ya think it could be related to that mad cow with the same genetic make-up ??? there were literally tons and tons of banned mad cow protein in Alabama in commerce, and none of it transmitted to cows, and the cows to humans there from ??? r i g h t $$$ ALABAMA MAD COW g-h-BSEalabama In this study, we identified a novel mutation in the bovine prion protein gene (Prnp), called E211K, of a confirmed BSE positive cow from Alabama, United States of America. This mutation is identical to the E200K pathogenic mutation found in humans with a genetic form of CJD. This finding represents the first report of a confirmed case of BSE with a potential pathogenic mutation within the bovine Prnp gene. We hypothesize that the bovine Prnp E211K mutation most likely has caused BSE in "the approximately 10-year-old cow" carrying the E221K mutation.

BSE Case Associated with Prion Protein Gene Mutation (g-h-BSEalabama) and VPSPr PRIONPATHY (see mad cow feed in COMMERCE IN ALABAMA...TSS)



http://prionpathy.blogspot.com/2010/08/bse-case-associated-with-prion-protein.html




her healthy calf also carried the mutation (J. A. Richt and S. M. Hall PLoS Pathog. 4, e1000156; 2008).

This raises the possibility that the disease could occasionally be genetic in origin. Indeed, the report of the UK BSE Inquiry in 2000 suggested that the UK epidemic had most likely originated from such a mutation and argued against the scrapierelated assumption. Such rare potential pathogenic PRNP mutations could occur in countries at present considered to be free of BSE, such as Australia and New Zealand. So it is important to maintain strict surveillance for BSE in cattle, with rigorous enforcement of the ruminant feed ban (many countries still feed ruminant proteins to pigs). Removal of specified risk material, such as brain and spinal cord, from cattle at slaughter prevents infected material from entering the human food chain. Routine genetic screening of cattle for PRNP mutations, which is now available, could provide additional data on the risk to the public. Because the point mutation identified in the Alabama animals is identical to that responsible for the commonest type of familial (genetic) CJD in humans, it is possible that the resulting infective prion protein might cross the bovine-human species barrier more easily. Patients with vCJD continue to be identified. The fact that this is happening less often should not lead to relaxation of the controls necessary to prevent future outbreaks. Malcolm A.

DEEP THROAT TO TSS 2000-2001 (take these old snips of emails with how ever many grains of salt you wish. ...tss)

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.)

END...TSS
