Abstract
Rhesus and cynomolgus macaques are currently used as ideal animal models of immune response. Major histocompatibility complex (MHC) molecules play important roles in the susceptibility and/or resistance to many diseases. In this study, MHC-DMA and -DMB were first characterized by sequencing and cloning in 28 unrelated cynomolgus macaques from Vietnam and 34 unrelated Chinese rhesus macaques. A total of 23 novel alleles, including six high frequency alleles, were identified in this study. Our results showed that the alleles with the highest phenotypic frequencies were Mafa-DMA(∗)02:04:03 (57.1%), Mafa-DMB(∗)03:01:02 (76.9%), Mamu-DMA(∗)02:01:04 (88.2%), and Mamu-DMB(∗)03:02:02 (85%), respectively, indicating that distribution and frequencies of alleles had a few differences between Chinese rhesus macaques and cynomolgus macaques from Vietnam. Interestingly, compared to the cynomolgus macaques, we found that the combination of Mamu-DMA(∗)02:01:04-DMB(∗)03:02:02 was detected in 27 (79.4%) of 34 monkeys, suggesting that the combination of the MHC-DMA and -DMB alleles was probably a characteristic feature of the Chinese rhesus macaques. Our results will greatly increase the value of the two species as models for biomedical research.
