A new hope?

No, not a Star Wars reference – and I'm a trekkie, anyway.

I was referring to this:

"Human hematopoietic stem/progenitor cells modified by zinc-finger nucleases targeted to CCR5 control HIV-1 in vivo"

In a nutshell, it's been known for a while that some people have what amounts to a natural protection against HIV infection due to a genetic variation that results in an impaired cell surface receptor that is essential for the virus to enter the cell (and thus infect it). This study apparently successfully replicated this process in mice, which could lead (a loooong time from now) to new ways to battle HIV infection (and AIDS, consequently).

Let's hope that this is the case and that if and when this becomes an actual therapy, that it is not so expensive as to be out of reach from those who mostly need it – especially in Africa.

Well, one can always hope.
