Detection by three cellular immunological techniques of the antigenic determinants of the Ly-Li system, expressed on human B lymphocytes.
A clear correlation was observed between the presence of an Ia-like antigenic B-cell system Ly-Li, detected serologically, and three cellular immunological techniques: [1] mixed lymphocyte reaction (MLR) inhibition by an anti-Li antiserum; [2] level of restimulation of anti-Ly-Li in-vitro-primed lymphocytes; and [3] detection of HLA-D alleles by homozygous typing cells. These results suggested that the allelic products detected serologically may be identical to those detected by the first two techniques, namely MLR inhibition and in-vitro-primed lymphocyte typing, and, possibly, HLA-D typing using homozygous typing cells, although the correlation was repeatedly found to be less clear for the last technique.
