Study finds genetic variants in HIV controllers

HIV controllers are people who are rare: they have high levels of HIV but do not develop AIDS giant dildo best ass , and they do not need medication. There are more than 300 of these genetic mutations, and they affect the way the human immune system recognizes HIV-infected cells through so-called HLA proteins, which present fragments of the virus on the surface of cells.

Approximately one in 300 people infected with HIV is an HIV controller. Researchers hope that by understanding how these controllers inhibit the virus's replication process chastity device , they may find new clues to developing a vaccine or other treatment.

Florencia Pereyra and a large research team conducted a genome-wide association analysis of patients participating in the International HIV Controllers Study. A genome-wide association study compares the genomes of different individuals to look for differences between one person and another that are associated with disease or other characteristics.

The researchers compared HIV controllers among Europeans, African-Americans and Hispanic descendants with HIV progressives. They found more than 300 variants with genome-wide significance. All of these variants are located in a region on chromosome 6 where the HLA gene is located. They then analyzed the efficacy of individual amino acids located within the HLA protein, and they found six independent meaningful residues, five of which were aligned along the grooves of the peptide that binds to the virus particle.

Although more research must be done to understand how these differences contribute to control over HIV, these findings suggest that the process begins by binding viral peptide antigens to HLA proteins male masturbation toys , which in turn affects the activation of T cells that recognize and destroy infected cells.
