Two T cell clones, one specific for I-Es/d plus myelin basic protein (BP) and another specific for I-Ak plus influenza virus have been demonstrated to cross-react with DBA/2 cells. Genetic and serological analyses have shown that each clone recognizes its respective priming antigen in association with self-major histocompatibility complex (MHC) determinants and each recognizes DBA/2 minor H antigens in association with allo I-Ad MHC antigens. Further analysis of these clones suggests (a) that the allo I-Ad MHC epitopes recognized by these clones are not shared with self-I-A epitopes, (b) that the virus or BP antigens do not cross-react with DBA/2 minor H antigens, (c) that these clones recognize different determinants on the DBA/2 minor H antigens, and (d) that there is a requirement for a specific association between the different MHC antigens and the non-MHC antigens to stimulate these clones. This specific associative recognition argues strongly for the "altered self" hypothesis.
