Abstract

Extensive polymorphism at the major histocompatibility complex (MHC) is thought to confer immune protection on populations. A New World primate, the cotton-top tamarin (Saguinus oedipus), has a high prevalence of ulcerative colitis and adenocarcinoma of the colon and dies after infection with several human viruses. Lymphocytes from all animals tested expressed one common MHC class I allelic product. Another MHC class I allelic product was expressed by 39 of 41 tested animals. Four other allelic products were also expressed on the lymphocytes of these animals at a frequency of >50%. MHC class II gene products, however, were polymorphic. Restriction fragment length polymorphism analysis confirmed that there were a limited number of cotton-top tamarin MHC class I alleles, whereas the MHC class II gene loci were polymorphic. This sharing of MHC class I alleles is unprecedented in a higher primate species and may play a role in the susceptibility of this endangered species to pathogens.
