hi all. here is another excellent blog to follow...written by a phD in cellular and molecular biology: http://cfidsresearch.blogspot.com/ i asked a question of one of the professors on the virology blog (whose link i posted earlier) and this is the response i received: "There has been a lot of talk in the scientific community this week about XMRV is Cleveland, and I spoke to a colleague that was in attendance. A considerable amount of talk centered around compounds to target XMRV - Isentress was one of the big ones, in addition to other integrase inhibitors. The only concern I have about AZT is the side effects - finding a doctor that will prescribe it, and monitor your bloodwork. You will also have to pay out-of-pocket, as provincial drug plans will not cover it. AZT has the advantage in terms of cost - about the cost of a large cup of coffee. Isentress will cost far more -$16 a day, but has very few side effects, and will bring viral load down faster. It might not be long before the natural health food stores start carrying chicoric acid - a natural integrase inhibitor from Echinacea, the only downside is that it cannot enter cells as readily as Isentress. There is a small risk that Isentress could cause autoimmunity in humans like it did with mice in the form of a lupus like illness, but this was only observed in mice with a certain genetic succeptibility."
