Scientists have pinpointed three genes that help some HIV-infected people rein in the virus and postpone the onset of AIDS in a finding that may help guide vaccine and drug development, they said Thursday.
They identified variations in the three genes that may help the immune systems of some people control the virus while others fail to control HIV proliferation.
The international team of researchers scanned the genomes of 486 HIV-infected people from Switzerland, Italy, Britain, Australia, Spain and Denmark.
