Abstract

Genes of the major histocompatibility complex (MHC) in the mouse (H-2 complex) have been shown to be an important factor in determining the immune responsiveness of various strains of mice to isolated antigens (e. g., lysozyme). The role of MHC genes in controlling the responsiveness of mice to multiple alloantigens is less well-defined, and although non-MHC genes have been shown to be important in determining responsiveness in some systems (e. g., haptens), they have not been demonstrated as yet to influence the rejection of vascularized organ allografts. In this study, the responsiveness of mice to vascularized cardiac allografts transplanted across well-defined major (H-2) and minor (non-H-2) histocompatibility barriers was investigated using congenic mice in 32 different donor/recipient combinations. The results show that both H-2 and non-H-2 gene products can act as target alloantigens for rejection. At the responder level, they may interact to effect responsiveness of a recipient strain to multiple alloantigens. In no case in this study has any one gene or group of genes been found to confer universal high or low responder status.
