Abstract: | When adherent mononuclear cells are removed from whole blood, the separated lymphocytes respond rapidly by proliferation to foreign cocultured lymphocytes. The reaction of responding cells against a pool of foreign stimulating cells can be detected in this rapid mixed lymphocyte culture (r-MLC) within 28 h and antigenic disparity between family members, differing for only one HLA haplotype, can be measured within 36 h. These early responses show genetic specificity corresponding to those observed in a standard MLC at 96 h. The involvement of similar cell populations in the regulation of early responses to allogeneic cells and increased responses to autologous cells in r-MLC, as well as accelerated responses in secondary MLC, is discussed. |
