abstract：:Antigenic variation is a characteristic feature of lentiviral infection. The SIV/macaque model of AIDS provides an ideal system in which to investigate the molecular basis of antigenic variation. The purpose of this study was to genetically map the nucleotide changes in env that alter the neutralization phenotype of S...
