I imagine most people here already know that Dr Peterson spoke at the CFSAC about people with other conditions who have also tested positive for XMRV. Among those were twin girls who have "childhood alzheimers" aka Neimann Pick type C disease. I did some research, wondering whether, if indeed they and we both have XMRV, their situation might shed some light on ours. They have a web site, here: http://addiandcassi.com/we-dare-to-dream-for-a-cure/ The basic takeaway I got there is that their symptoms are caused by excessive buildup of cholesterol within the cells, particularly in the liver, spleen, and brain. They are being treated experimentally with a simple sugar compound known to have the capacity to remove cholesterol. It went on to say that cholesterol dysfunction is an important part of HIV replication, and that this substance shows promise in HIV prevention and treatment as well. News segment about all this is here: http://www.youtube.com/watch?v=lnc_bQCNoOw Now I'm just going to throw something out there from my own experience. This all struck a particular chord with me, as the only treatment I've found that helps me is the "liver flush," per the Hulda Clark school. http://www.drclark.net/en/cleanses_clean-ups/liver_cleanses/liver_cleanse.php (Believe me, I know this is the height of quackery - all I can say is, it really, really helps me. I've gone from functioning at a 2 to a steady 5-6. I do it weekly; when I've missed it, I immediately start to relapse.). The rationale of the flush is that it flushes gallstones out of the liver and gallbladder; such stones are composed primarily of cholesterol. I've always been skeptical about this - why, I thought, would I have so many stones in my liver week after week? But - perhaps if I have some retrovirus-related cholesterol dysfunction? One other factoid - the only abnormal test result in my bloodwork, ever, was a strangely high cholesterol level. So, I have no idea what this all might mean, but thought it might be of some interest to others.
