Di-allelic alloantigenic systems on subsets of T cells

Abstract

Sera obtained from multiparous women and some of other origin contain antibodies which react with antigens on T cell subsets. These antibodies recognize two distinct diallelic systems, one of which is mainly present on T gamma cells while the other is present on T mu cells. The sera that reacted with the T gamma cells formed a pattern consistent with that of a diallelic system which we have called TCA system with alleles TCA 1 and TCA 2; the sera which reacted with the T mu cells formed a pattern consistent with another diallelic system, independent from TCA, which we have designated the TCB system, with alleles TCB 1 and TCB 2.
