Abstract
EXPRESSION of the major transplantation antigens in humans is generally considered to be controlled by the genes of the HL-A region1-4. Skin, kidney and bone marrow transplants usually survive longer when donors and recipients are HL-A identical than when they are not5-7. However, the fact that grafts are still rejected with HL-A identity and negative mixed lymphocyte reactivity (MLR)8-11 strongly suggests the presence of minor transplantation antigens. The major problem to date has been the development of in vitro assay systems to detect these antigens.
