I just got results.. positive PCR. Serum pending. Ive not followed the threads, info much because I really didnt think I had this but now that I know I do, it makes sense... esp with my family history. So.. since I am starting from ground up a bit here.. can someone give be a primer on this retro mlv mix.. first it was xmrv and now its a possibly mix or grab bag of mlvs? Is xmrv as a retro viral entitiy still on the table as well? Then to get really basic... what is the potential, probable, theorized role in cfs.. it downregulates the immune system once triggered? How? It directly causes the cytokine flares, specific ones identified on grfaph on another thread.. ?? Can we make a sticky of basic info for people like me coming in behind and needing to play catch up? Is there a basic article, info out there to refer to? Im getting infor futher down the trail and Im at the beginning. Also a bit of a learning curve and an inflammed brain at the moment. Thank you!
