Yes... any reports on Silverman's position are very welcome... any other news regarding XMRV too, of course.

Yeah - I really want to hear from the prostate cancer guys. And Ruscetti.

So far Mikovits has been looking pretty isolated. Is that going to change?

Isolated in what sense? Within the people not "believing" the contamination line i don't know if she's so isolated. Maybe at the moment it's not always the same what we hear through the media and what researchers really think.

Esther, I bet Dr Mikovits is having a great time and talking to loads of other useful doctors. She always looks popular at other conferences and had people wanting to talk to her. With Rushetti and Silverman there she's got allies.

p.s. I was glad to see that this guy was there. He is the one who "poked his head over the parapet" and commenting on how the genetic diversity of XMRV could be explained by one common vector

By 'isoloated' I meant that she's the only scientist who still seems to be publicly defending the XMRV/CFS link. We've not really heard proper replies from Singh/Silverman/etc about the recombination/contamination thing as it applies to their PC work either.

I wonder if that is a question of personal style, Esther? Times and manners are changing. Ideas of professional conduct are changing. People want to have more things out in the open and discussed that were hidden years ago. We no longer accept that doctors would lie about patients having cancer or expect them to die quietly without saying things.

It may be, that, Dr Mikovits had a real grounding in the politics of CFS and decided that it would be best for everything to be as transparent as possible and out in the open.

Dr's S/S may not be interested in CFS politics or even brave enough to enter the fray. I just don't know.

As a woman I'm really proud of Dr Mikovits. We hoped that when more women entered medicine that they would change it for us. I like her outspokenness and determined spirit. Maybe she just works best that way.

I think there could well be two narratives going on here, one for the public, and one for the researchers.

Thanks, Jemal. It's a shame there's nothing by Silverman in this list. But probably there is more than enough other interesting material, from what i've seen. But i leave it to "the smart people", like Dr. Bell does :cool:

Silverman will present tomorrow I think, his abstract hasn't been published yet. It will be 241 in the list I think, so there's more XMRV stuff coming!

Hi Silverman was last author of one of the papers on XMRV and mucosa. The evidence is growing that XMRV is sexually transmissible. Another of these abstracts lists a new drug for treating XMRV, which is not an antiviral. Finally, and this could be huge despite sounding minor, the range of cell types XMRV can infect might be larger than expected - it is not limited to the XPR1 cell surface receptor. I await more info from the actual presentations with interest. Bye, Alex

geez...more cell types infected? new drug?? woah.

i called wpi on thurs....dr. mikovits was in NYC and then headed to belgium....looks like lots going on behind the scenes!


its all over the net that dr. beiger's study is going to be positive..so why worry?

Read this and see if you still have doubts about XMRV:

Development of XMRV producing B Cell lines from lymphomas from patients with Chronic Fatigue Syndrome
Francis Ruscetti, Vincent C Lombardi, Michael Snyderman, Dan Bertolette, Kathryn S Jones, Judy A Mikovits.
http://www.retrovirology.com/content/pdf/1742-4690-8-s1-a230.pdf


And here's more evidence that XMRV is a human virus:

Restricted infection of xenotropic murine leukemia virus-related virus in human lymphoid tissue
Marta Curriu, Jorge Carrillo, Marta Massanella, Elisabet Garcia, Bonaventura Clotet, Julian Blanco, Cecilia Cabrera.
http://www.retrovirology.com/content/pdf/1742-4690-8-s1-a208.pdf

The lymphoma paper is quite dramatic, isnt it?
I remember this was the abstract for the NYAS talk JM gave.

I'm not sure how to interpret the lymphoid tissue one. Am I correct in thinking that there were no antibodies to XMRV env detected? Do you think the lack of immune activation would show XMRV to be more of a threat? Precisely because the body does not react to it as such?
I suppose this study is fairly limited in scope. Just tonsilar tissue over a fairly limited time (14 days?) may not be enough to gauge how the body as a whole would respond.

Singh's was supposed to be positive, too, and then she found an alternate explanation for her results. We can hope for a positive study, but as they saying goes, we might not want to "count our chickens before they hatch" or before they publish, as the case may be.
