Abstract We have used seven HLA-D homozygous typing cells (HTC) in a comparative study of the DRw8 antigen complex in three racial groups. Three distinct HLA-D specificities were recognized, each associated with HLA-DRw8. Four of the HTC defined a DRw8-associated HLA-D specificity designated 8.1, one defined a specificity designated 8.2, and two defined a specificity designated 8.3. Each of the three spec cities showed an association with a distinct racial group: Dw“8.1” in Caucasians, Dw“8.2” in Pacific Northwest Indians, and Dw“8.3” in Orientals. An informative primed lymphocyte (PLT) cell generated against a Dw“8.1” haplotype was able to distinguish 8.1 from 8.2 and 8.3. Using selected anti-DRw8 sera, a serologic distinction between 8.1 and 8.3 could also be made. It was thus possible, by using both cellular and serologic techniques in a comparative population study, to recognize at least three HLA-D-defined splits of the DRw8 haplotype.
