Screening and confirmatory testing of MHC class i alleles in pig-tailed macaques

Abstract

Pig-tailed macaques (Macaca nemestrina) are a commonly studied primate model of human AIDS. The Mane-A1*084:01 MHC class I allele (previously named Mane-A*10) is important for the control of SIV infection by CD8+ T cells in this model. Validated methods to detect this allele in large numbers of macaques are lacking. We studied this MHC allele using sequence-specific PCRs in 217 pig-tailed macaques and identified 75 (35%) positive animals. We then performed massively parallel pyrosequencing with a universal 568-bp MHC class I cDNA-PCR amplicon for 50 of these 75 macaques. All 50 animals expressed Mane-A1*084:01 or closely related variants of the Mane-A1*084 lineage. Mane-A1*084 transcripts ac..
