AbstractPurpose of review
Dominant host factors modifying the susceptibility to HIV-1 include diversity in the major histocompatibility complex class I, and alleles of chemokine and chemokine receptor genes. Additional host factors, particularly those determining cell permissiveness to viral replication, are expected to play a significant role in HIV-1 pathogenesis.Recent findings
A growing number of publications (n = 32) propose new variants (n = 27) modifying HIV-1 susceptibility in genes (n = 17) needed for the viral lifecycle, in antiviral innate defense, and in a number of soluble and membrane proteins.Summary
Although there are multiple publications describing putative associations of host genetic variants and susceptibility to HIV-1, most reports are yet to be confirmed by subsequent publications, or have led to conflicting data among laboratories.
