title: Peptide dependence of major histocompatibility complex class II specific alloreactive responses.
abstract: Splenic cells from transgenic mice, in which a single peptide is complexed to all major histocompatibility complex (MHC) class II molecules, are found to be incapable of triggering primary allogeneic mixed lymphocyte/leucocyte reactions (MLR) when co-cultured with lymphocytes from MHC class II congenic mouse strains. In addition, a single HLA-DR-blocking peptide can completely abrogate the capacity of splenocytes from chimeric HLA-DR/H2-E transgenic mice to stimulate primary MLR of T cells from wild-type mice. These results indicate that the primary alloreactive response is directed against a multitude of peptides presented by allogeneic MHC molecules.
