Scientists have discovered three very strong antibodies that kill various HIV strains. The strongest of these antibodies actually manages to neutralize 91% of known HIV strains. While this isn't exactly a cure to HIV or AIDS, it's certainly a step in the right direction. [WSJ]
I'm no immunologist, but isn't there a huge difference between an antibody killing a virus in a vacuum, and it doing the same work inside a human body? I was under the impression that the problem with curing HIV was that the virus attacks your immune system cells, the very ones that would get rid of other infections. Isolating an antibody that can destroy the virus is a huge step in the right direction, but even if you give a person the antibody's so that their body recognizes it and starts producing more, wouldn't they still be susceptible to the virus since it kills the very cells making the antibody? Besides that, the virus "hides" away INSIDE cells, making it hard to get rid of them.
Again, I'm no immunologist, forgive me if this is stupid.
