| hla class i alleles associated with susceptibility or resistance to human immunodeficiency virus type 1 infection among a population in chaco province, argentina. | host genetic factors, such as hla alleles, are important in human immunodeficiency virus (hiv) infection and its progression to aids. hla class i gene products are involved in peptide presentation, and each allele is responsible for presenting a different set of peptides to cytotoxic t lymphocytes. the increase or decrease in the frequency of certain alleles in hiv-1-positive versus control subjects would suggest that alleles play a role in susceptibility to or protection against this viral infe ... | 2000 | 11010837 |
