title: The role of H-2 in T cell recognition of Mls.
abstract: The role of H-2 was evaluated in T cell recognition of Mls-encoded antigens during primary mixed lymphocyte responses (MLR). Mlsc was used as a stimulating determinant in MLR and its recognition by T cells was assessed by linear regression analysis under culture conditions in which (A x B)F1 responder cell number was the factor limiting total response. Results of such experiments indicated the presence of distinct (A x B)F1 responder T cell subpopulations capable of differentially recognizing the foreign Mls antigen in association with one or the other parental H-2 haplotype. These findings demonstrate that T cells do not recognize Mlsc products in isolation, but rather are restricted to recognition of Mlsc in the context of "self" H-2 determinants.
