The researchers conducted clinical tests on 40 AIDS patients in the United States.
AK602 not only proved effective against viruses that had become resistant to other drugs, but it also caused almost no side effects, the team said.(IHT/Asahi: July 7,2005)
detta said:CCR5 is a chemokine receptor that is expressed primarily on cells of the immune system (B-cells, T-cells, macrophages). Basically, it is important for the immune response because it helps activate the cells when there is an infection. So what I think this is about is that they found something that blocks the receptor so that HIV doesn't recognize the cell since certain strains of HIV need to recognize this receptor to infect the cell. I'm not sure how novel this idea is since I think other drugs have been made with similar functions but I don't know the specifics. Also, apparently there are other receptors that HIV can recognize although I believe this is the dominant one.
