PG - 2134-43 LID - 10.11406/rinketsu.56.2134 [doi] AB - Human immune responses are principally characterized by the human leukocyte antigen (HLA) system, a diverse set of cell surface molecules encoded by the major histocompatibility complex gene cluster on the short arm of chromosome 6. Among various members of the HLA family, the best characterized are the classic highly polymorphic class I and class II molecules that are responsible for antigen presentation to T cells and regulation of NK cell functions. In allogeneic hematopoietic cell transplantation, sophisticated approaches to donor-recipient allele-level matching at 3 class I (HLA-A/B/C) and 3 class II (HLA-DRB1/DQB1/DPB1) loci have been proven to lower the risk of immunologic complications such as graft failure and graft-versus-host disease, and possibly to confer effective graft-versus-malignancy effects. Future areas of research include clarifying the role of relatively non-polymorphic non-classical HLA molecules (HLA-E/F/G, HLA-DM/DO) and polymorphic/non-polymorphic class I-related molecules (MICA, MICB, HFE, MR1, CD1, FcRn) in the immune regulation that follows hematopoietic cell transplantation.
