The HLA-A locus represents a single copy gene that displays abundant allelic polymorphism in the human population, whereas, in contrast, a nonhuman primate species such as the rhesus macaque (Macaca mulatta) possesses multiple HLA-A-like (Mamu-A) genes, which parade varying degrees of polymorphism. The number and combination of transcribed Mamu-A genes(More)
The major histocompatibility complex class I gene repertoire was investigated in a large panel of rhesus macaques of Chinese origin. As observed in Indian animals, subjects of Chinese derivation display Mamu-B gene copy number variation, and the sum of expressed genes varies among haplotypes. In addition, these genes display differential transcription(More)
In the absence of treatment, most HIV-1-infected humans develop AIDS. However, a minority are long-term nonprogressors, and resistance is associated with the presence of particular HLA-B*27/B*57 molecules. In contrast, most HIV-1-infected chimpanzees do not contract AIDS. In comparison with humans, chimpanzees experienced an ancient selective sweep(More)
In the human population, five major HLA-DRB haplotypes have been identified, whereas the situation in rhesus macaques (Macaca mulatta) is radically different. At least 30 Mamu-DRB region configurations, displaying polymorphism with regard to number and combination of DRB loci present per haplotype, have been characterized. Until now, Mamu-DRB region genes(More)
The Mamu-A, Mamu-B, and Mamu-DRB genes of the rhesus macaque show several levels of complexity such as allelic heterogeneity (polymorphism), copy number variation, differential segregation of genes/alleles present on a haplotype (diversity) and transcription level differences. A combination of techniques was implemented to screen a large panel of pedigreed(More)
BACKGROUND In sharp contrast to humans and great apes, the expanded Mhc-B region of rhesus and cynomolgus macaques is characterized by the presence of differential numbers and unique combinations of polymorphic class I B genes per haplotype. The MIB microsatellite is closely linked to the single class I B gene in human and in some great apes studied. The(More)
In humans, the single polymorphic B locus of the major histocompatibility complex is linked to the microsatellite MIB. In rhesus macaques, however, haplotypes are characterized by the presence of unique combinations of multiple B genes, which may display different levels of polymorphism. The aim of the study was to shed light on the evolutionary history of(More)
Indian and Chinese rhesus macaques are often used in biomedical research. Genetic analyses of the major histocompatibility class I region have revealed that these macaques display a substantial level of polymorphism at Mamu-A and Mamu-B loci, which have been subject to duplication. Only a few Mamu class I allotypes are characterised for their(More)
