THE LYMPHOCYTE ACTIVATING INFLUENCE OF THE HLA‐A REGION

Abstract

Six individuals with an established recombination between the HLA-A and the HLA-B loci of the major histocompatibility complex have been tested in unilateral mixed lymphocyte cultures with other members of their families. A weak, but statistically significant lymphocyte activating influence of the HLA-A chromosomal region has been observed.
