Rapid Multiplex Genotyping of 20 HLA-A*02:01 Restricted Minor Histocompatibility Antigens

Identification of 4 new HLA-DR-restricted minor histocompatibility antigens as hematopoietic targets in antitumor immunity.

Potent graft-versus-leukemia (GVL) effects can be mediated by donor-derived T cells recognizing minor histocompatibility antigens (mHags) in patients treated with donor lymphocyte infusion (DLI) for relapsed hematologic malignancies after HLA-matched allogeneic stem cell transplantation (alloSCT). Donor-derived T cells, however, may not only induce GVL, but also mediate detrimental graft-versus...

Minor histocompatibility antigens.

ISTOCOMPATIBILITY antigens are a group of cell H membrane alloantigens that can trigger T-lymphocyte proliferative and/or cytolytic activity in vitro and may initiate graft rejection or graft-versus-host disease (GVHD) in vivo. AB0 and related antigens, whose presence on vascular endothelial cells may provoke antibody-mediated graft rejection, are excluded from this group because they do not in...

Human minor histocompatibility antigens.

Disparities in minor histocompatibility antigens between HLA-matched organ and bone marrow donors and recipients create a potential risk for graft failure and graft-versus-host disease. These conditions necessitate lifelong pharmacological immunosuppression of organ and bone marrow transplant recipients. Recent technical advances have resulted in the identification of the chemical nature of the...

Polymorphism of human minor histocompatibility antigens: T cell recognition of human minor histocompatibility peptides presented by HLA- B35 subtype molecules

To investigate the polymorphism of human minor histocompatibility (mH) antigens, PBLs from 23 Japanese individuals and 25 German individuals with HLA-B35 were studied by using four human mH antigen-specific, HLA-B35-restricted CTL clones. The CTL clones killed PHA-stimulated PBLs from all 23 Japanese individuals. On the other hand, they killed the PHA-stimulated PBLs from 19 of 25 German indivi...
