The major genetic determinants of HIV-1 control affect HLA class I peptide presentation.
Science
December 2010
Article Synopsis
- Researchers conducted a genome-wide association study focusing on HIV-1 controllers and progressors to understand genetic factors influencing chronic viral infections.
- They discovered over 300 significant single-nucleotide polymorphisms (SNPs) specifically within the major histocompatibility complex (MHC), emphasizing its importance for infectious diseases.
- Key findings indicate that specific amino acids in HLA proteins, especially HLA-B and HLA-C, significantly influence the interaction between HLA and viral peptides, affecting the control of HIV infection.
Both HIV and its treatment, particularly protease inhibitors, can cause lipidemia similar to that seen with the metabolic syndrome. The most notable effects are elevated triglyceride levels and decreased high-density lipoprotein cholesterol levels, with or without elevated low-density lipoprotein cholesterol (LDL-C) levels. Current recommendations by the National Cholesterol Education Program for HIV-infected persons focus on LDL-C as the primary target of therapy: after lifestyle modifications, statins should be used to lower LDL-C levels.
