Yes, 1% of Caucasians with CCR5 Delta32 mutation are naturally immune to HIV.

Very recently, a paper was published in Nature showing the second case of HIV-1 infected patient cured after the CCR5Δ32/Δ32 haematopoietic stem-cell transplant. This work remarkably explains how it was possible to fulfill such extraordinary achievement and throughout the explanation it also gives a huge amount of knowledge about the existing HIV-1 infection resistant population.

I can't stress enough how important this paper is for everyone who wants to learn more about HIV-1 infection field.

Hope it helps.

Yes there are persons who are naturally immune to HIV. Those who are deficient for CCR5 are not infected with HIV even when exposed to the conditions of HIV transmission and that become a selective advantage to them.

Oooh Ok.

i'm hearing this for the first time.

Can't CCR5 mutations be injected or built into people.

Just asking on a layman bases.

Just to save lives.

CCR5 is a chemokine receptor on WBCs and determines the entry of HIV. While other mutations in the gene causing damages, this D32 mutation does not cause damage and immune to entry of HIV. On the other side, it may also prevent other pathogens entry and subsequently damage the entire immune system. At least, there is now increasing in the need for hematopoietic stem cell donors with a homozygous defect in the CCR5 receptor.

Ccr5 negative are NOT immune, they are just not subsceptible to infection.

This article is something relevant to the discussion: (not about individuals who are naturally immune to HIV, but who can stay healthy and control HIV infection)
