analysis of [ 35s ] methionine-labeled proteins by the method of two-dimensional polyacrylamide gel electrophoresis indicated that dr+ , but not dr- , cells biosynthesize dr molecules dr+ cells stimulated strongly in the autologous and allogeneic mixed lymphocyte reactions ( mlr ) and supported t cell proliferation to soluble antigens , whereas dr- cells stimulated in the allogeneic mlr but failed to stimulate in the autologous mlr or to support t cell proliferation to soluble antigens .
