Locally produced antisera and antisera received through the Seventh International Histocompatibility Workshop exchange were investigated for specific B-cell cytotoxic activity in a panel of 95 unrelated HLA-D-typed donors. A number of sera formed clusters defining eight B-cell specificities which were strongly associated (p<0.001) to the HLA-D determinants Dw1-8. In panel investigations, only four triplets occurred. In five HLA recombinant families, these B-cell specificities followed the HLA-B-D chromosomal region, and in one -B/D recombination, DRw1 traveled with -Dw1. In MLCs between panel donors sharing zero, one, or two HLA-D-related B-cell specificities, significantly weaker MLC stimulation was observed with increasing compatibility, the median relative responses being 100, 52, and 17 percent, respectively. It is concluded that B cell-specificities HLA-DRw1-7 and WIA8 are probably coded for by HLA-D; they are excellent markers for the HLA-D determinants, which can thus be typed for by serological means; and serological typing for HLA-D has great value in predicting the outcome of MLCs.
