title: Comprehensive identification of MHC class II alleles in a cohort of Chinese rhesus macaques.
abstract: Rhesus macaque is a very important animal model for various human diseases, especially for AIDS and vaccine research. The susceptibility and/or resistance to some of these diseases are related to the major histocompatibility complex (MHC). To gain insight into the MHC background and to facilitate the experimental use of Chinese rhesus macaques, Mamu-DPB1, Mamu-DQB1, and Mamu-DRB alleles were investigated in 30 Chinese rhesus macaques through gene cloning and sequencing. A total of 66 alleles were identified in this study, including 14 Mamu-DPB1, 20 Mamu-DQB1, and 30 Mamu-DRB alleles as well as 2 high-frequency Mamu-DPB1 alleles. Interestingly, one of the high-frequency Mamu-DPB1 alleles had been undocumented in earlier studies. Eleven of the other alleles, including four Mamu-DPB1, three Mamu-DQB1, and four Mamu-DRB alleles were also novel. Importantly, like MHC-DRB, more than two Mamu-DPB1 sequences per animal were detected in 13 monkeys, which suggested that they might represent gene duplication. Our data also indicated quite a few differences in the distribution of MHC class II alleles between the Chinese rhesus macaques and the previously reported Indian rhesus macaques. To our knowledge, our results revealed comprehensively the combination of MHC II alleles. This information will not only promote the understanding of Chinese rhesus macaque MHC polymorphism but will also facilitate the use of Chinese rhesus macaques in studies of human disease.
