title: Responsiveness to HY antigen Ir gene complementation and target cell specificity.
abstract: The H-2 restricted nature of the cytotoxic T cell responses to the HY antigen in mice has been reviewed, together with mapping data for the H-2 K and/or D association of responses to male cells of the following haplotypes: H-2b, H-2d, H-2k, H-2s. Ir gene complementation is implicated in the HY response of a number of F1 mice derived from non-responder parental haplotypes, and in one recombinant strain. Thus, at least two and possibly more Ir genes are involved in the anti-HY response, in addition to the K and/or D gene products with which HY is obligatorily associated, certainly at the target cell level.
