摘要: Lymphocytes alloactivated by Dw3 homozygous typing cells were cloned the method of limiting dilution and cultured for prolonged periods using T-cell growth factor irradiated pooled leukocytes (as feeder cells). Restimulation specificity two clones functioning as primed lymphocyte reagents was investigated in panel family studies. Cells from one (12-2) always specifically stimulated HLA-Dw3 antigens shared between original priming stimulating cells. In an informative KOH, however, this clone seemed to detect a split cluster. other (12-8) failed respond expressed or cells; rather, restimulation be associated with expression Dw4 antigens. Family segregation analysis did not support conclusion since products segregated three Dw3-bearing haplotypes none Dw4-bearing haplotypes. This suggested that 12-8 may responsive different those detected
