Abstract
Abstract The acute or chronic infection of HIV1 resulting to AIDS pandemics is one of the major causes of morbidity and mortality worldwide. The infection, prevalence and propagation of HIV1 depend both on adaptive mutation in virus and host genetic factors. Virus infection to human CD4+ immune cells together is assisted and restricted by various host factors. Presence of mutations in CCR2, CCR5 and CXCR4 ligands SDF1 are associated to protection against HIV1 infection and restriction to AIDS progression. Globally, individuals in various populations harbouring CCR2 (64I), CCR5 (Δ32) and SDF1-3’A mutations are less susceptible to HIV1 infection and decipher delayed onset of AIDS. This review emphasizes the distribution and functional importance of CCR2 (64I), CCR5 (Δ32) and SDF1 (3’A) mutations in protection against HIV1 infection. Lastly the review discuss how CCR2, CCR5 and SDF1 can be explored for development of antagonistic for protection against HIV1 infection.
