The significance of HLA-DRB1 matching on clinical outcome after HLA-A, B, DR identical unrelated donor marrow transplantation.
Despite matching for serologically defined HLA-A, B, DR antigens, acute graft-versus-host disease (GVHD) is a major complication contributing to increased morbidity and mortality in patients who undergo marrow transplantation from unrelated donors. The extent to which unrecognized mismatching for alleles that encode DR1-DR18 contribute to the increased risk of acute GVHD and overall survival is...
متن کاملDonor-specific anti-HLA Abs and graft failure in matched unrelated donor hematopoietic stem cell transplantation.
Anti-HLA donor-specific Abs (DSAs) have been reported to be associated with graft failure in mismatched hematopoietic stem cell transplantation; however, their role in the development of graft failure in matched unrelated donor (MUD) transplantation remains unclear. We hypothesize that DSAs against a mismatched HLA-DPB1 locus is associated with graft failure in this setting. The presence of ant...
متن کاملMHC microsatellite diversity and linkage disequilibrium among common HLA-A, HLA-B, DRB1 haplotypes: implications for unrelated donor hematopoietic transplantation and disease association studies.
Twenty-two human major histocompatibility complex (MHC) region microsatellite (Msat) markers were studied for diversity and linkage disequilibrium (LD) with HLA loci in hematopoietic cell transplant recipients and their HLA-A, HLA-B, HLA-C, HLA-DRB1, and HLA-DQB1 allele-matched unrelated donors. These Msats showed highly significant LD over much of the MHC region. The Msat diversity of five com...
متن کاملAllele Frequencies of HLA-A, B and DRB1 among People of Fars Ethnicity Living in Tehran
Background: Human leukocyte antigens (HLA) are polymorphic cell surface proteins. Distribution of HLA alleles vary among different racial and ethnic populations in unrelated stem cell registries. Determination of HLA allele frequencies in different ethnic groups is useful for population genetic analyses. Materials and Methods: Based on data available from the Iranian Stem Cell Donor Registry...
متن کاملNK-cell education is shaped by donor HLA genotype after unrelated allogeneic hematopoietic stem cell transplantation.
The rules governing natural killer (NK)-cell education in the allogeneic environment created by unrelated hematopoietic stem-cell transplantation (HSCT) are still largely elusive, especially in an unrelated donor setting. NK-cell inhibitory receptors for self-human leukocyte antigen (HLA) play a central role in the acquisition or maintenance of NK-cell functional competence. Therefore, the resp...
