Genetic Variation Produces Weaker HIV Strain

According to new research from the Center for the AIDS Program of Research in South Africa, individuals with an immunity gene called HLA may be mutating a weaker strain of HIV, making it less potent when transmitted, reports Reuters (africa.reuters.com, 3/21).

The South African study followed 21 women who were recently infected with the weakened strain of the virus. The article notes that the women had much lower viral loads than those carrying strains that had not been mutated by HLA.

“It is pretty well established [that] if you have HLA genes you are better off,” study co-author Carolyn Williamson told Reuters.

Everyone has HLA genes. HLA stands for Human Leukocyte antigen. All humans have HLA genes. The article is poorly written and lacks peer review.

Well. Waht are the HIV/AIDS researchers waiting for???. Got take blood samples of those people with HLA genes and see if they can come up with a way to create a med or a vaccine that would weaken the actual HIV-1 and HIV-2 strains that we already have. Yeahh, I know. I'll keep on dreaming!!!
