pubmed:abstractText
Cytotoxicity tests with alloantisera were used to study the expression of HLA-D region antigens in HLA-DR-null mutants of a human lymphoblastoid cell line. The initial cell line contained just one copy of the MHC as a haplotype that included DR1 and MB1/MT1. Gamma ray mutagenesis of the single haplotype cells followed by selection with complement and an anti-DR monoclonal antibody were then used to isolate DR-null mutants. Two categories of mutants were identified with a panel of alloantisera. Expressions of DR1 and MB1/MT1 were simultaneously lost in four mutants. Nine mutants still expressed MB1/MT1 but had lost the expression of DR1. The dissociated loss of expression of MB1/MT1 and DR1 antigens is evidence for separate genetic control of these alloantigens. The methods used exemplify a versatile approach for conveniently inducing separations of closely linked loci of the MHC.
