title: Biochemical characterization of Syrian hamster cell surface alloantigens. III. Hamster alloantisera immunoprecipitate class II-like, but not class I-like, molecules.
abstract: Twelve hamster alloantisera, recently produced by mutual immunizations of domestic inbred strains and recently wild, partially inbred lines, identify two cell surface molecules, 29 and 39 kilodaltons, expressed by hamster lymphohematopoietic cells. Their expression on lymph node and spleen cells suggests that hamster T cells display cell surface class II homologues. None of the alloantisera identify putative hamster homologues of class I MHC molecules. The data are consistent with the hypothesis that hamsters possess a chromosomal region, tentatively designated Hm-1, that comprises genetic loci encoding alloantigens detectable by mixed lymphocyte reactivity and by serology, a region that resembles the I region of murine H-2.
