Abstract

Pig-tailed macaques (Macaca nemestrina) provide important animal models in biomedical research, but utility of this species for HIV and other disease pathogenesis research is limited by incomplete knowledge of major histocompatibility complex (MHC) class I genetics. Here, we describe comprehensive MHC class I genotyping of 24 pig-tailed macaques, using pyrosequencing to evaluate a 367-∈bp complementary DNA (cDNA)-PCR amplicon spanning the highly polymorphic peptide-binding region of MHC class I transcripts. We detected 29 previously described Mane transcripts, 90 novel class I sequences, and eight shared MHC class IB haplotypes. We used this genotyping data to inform full-length MHC class I cDNA allele discovery, characterizing 66 novel full-length transcripts. These new full-length sequences nearly triple the number of Mane-B cDNA sequences previously characterized. The comprehensive genotypes and full-length Mane transcripts described herein add value to pig-tailed macaques as model organisms in biomedical research; furthermore, the coordinated method for MHC genotyping and allele discovery is extensible to other less well-characterized nonhuman primate species.
