Encodes2
BACKGROUND: The major histocompatibility complex (MHC), which encodes molecules that recognize various pathogens and parasites and initiates the adaptive immune response in vertebrates, is renowned for its exceptional polymorphism and is a model of adaptive gene evolution. (bvsalud.org)
By stimulating peripheral blood lymphocytes with HLA-B8+ EBV-transformed B lymphoblastoid cells, the primary virus-specific CTL response was shown to include specificities for two HLA-B8-restricted antigenic determinants, FLRGRAYGL and QAKWRLQTL, which are encoded within the latent EBV nuclear antigen EBNA-3.
