It's evolution, baby. I remember seeing a Richard Dawkins programme about two prostitutes in Kenya who had developed an immunity to HIV. Its what happens.

How did that happen?

[dncingmalkavian]

Nature does that sometimes.

Some people are just naturally resistant to HIV; there's a mutation that makes the virus have extreme difficulty invading their cells. There's actually a case of an accidental AIDS "cure" -- somebody got a bone marrow transplant from a donor who was resistant, and the transplanted immune system was resistant to HIV.

Was anything mentioned about the mechanism of that immunity, or are we still trying to figure that out? (Because that's some pretty important info right there)

My med school friend was telling me about the CCR 5 protein rceptor present and how people with two copies of Delta-32 mutation, which deletes a portion of the CCR5 gene, are resistant to macrophage strains of HIV-1 infection.
