Immunological reactivity results from differences between the transplant host and donor for cell surface determinants known as histocompatibility antigens. Histocompatibility antigens that provoke the most severe transplant reactions are encoded by a series of genes that reside in a discrete chromosomal region termed the major histocompatibility complex (MHC) (Amos 1968). Genes of the human leu...

Forty-eight consecutive patients at high risk for corneal graft rejection were transplanted with corneas from donors selected on the basis of a negative lymphocyte crossmatch, ABO blood group compatibility, and maximized HLA-A, -B matching. Graft survival in this study group was compared to a retrospective control group of 72 consecutive high-risk transplants performed in patients receiving ran...

The degree of genetic divergence which has occurred between a number of inbred strains of mice and between two sublines of inbred rats was assessed by determining the fate of inter-subline skin grafts. Sublines which had been separated for 29 and 42 generations possessed no detectable incompatibility, while three combinations of sublines judged to have been maintained apart for from 123 to 129 ...

brought new methods of leukocyte and tissue typing. The MLC2 reaction (3) allows the reproduction in vitro of the reaction of transplantation immunity in vivo (1) by the selective measurement of antigenic incompatibilities for the important transplantation antigens. Specific tumor cell antigens are known to be weaker than transplantation antigens. We undertook a program to determine if MLC is c...

Unrelated haematopoietic stem cell transplantation (HSCT) has evolved from an experimental protocol to a potentially curative first-line treatment in variety of haematologic malignancies. The continuous refinement protocols and supportive care paired with ongoing achievements the technological field histocompatibility testing enabled this transformation. Without doubt, HLA matching is still for...
