TCRBV20S1 allele frequencies vary among human populations


T lymphocytes recognize antigen presented by self major histocompatibility complex (MHC) antigens and their fine specificity is determined by the antigen receptor (TCR) present on the cell surface. In contrast to the high degree of polymorphism of MHC antigens, polymorphism detected in TCR gene segments appears to be limited. There are limited numbers of… (More)
