Human B‐blast specific target determinants in CML: a family study

Abstract
Human B blast specific target determinants, selectively identified on pokeweed mitogen stimulated purified B lymphoblasts by in vitro generated cytotoxic T lymphocytes, have previously been studied in the population and showed association to and inclusion of HLA-DR gene products. This report indicates that B blast specific target determinants apparently are products of genes which, in a codominant mendelain way, segregate with the HLA haplotypes in 4 selected Dutch families. Tests of families with HLA-B/D, DR and HLA-D, DR/GLO recombinations show that human B blast specific target determinants are coded from loci (locus) in the HLA-D region, between HLA-B and GLO.
