ジャーナル: Immunity / 年: 2025 タイトル: Topography of the HLA-A protein enforces shared and convergent immunodominant B cell and antibody alloresponses in transplant recipients. 著者: John T Killian / R Glenn King / Aaron C K Lucander / James L Kizziah / Christopher F Fucile / Ruben Diaz-Avalos / Shihong Qiu / Aaron Silva-Sanchez / Betty J Mousseau / Kevin J Macon / Amanda ...著者: John T Killian / R Glenn King / Aaron C K Lucander / James L Kizziah / Christopher F Fucile / Ruben Diaz-Avalos / Shihong Qiu / Aaron Silva-Sanchez / Betty J Mousseau / Kevin J Macon / Amanda R Callahan / Guang Yang / M Emon Hossain / Jobaida Akther / Daryl B Good / Susan Kelso / Julie A Houp / Frida Rosenblum / Paige M Porrett / Song C Ong / Vineeta Kumar / Erica Ollmann Saphire / John F Kearney / Troy D Randall / Alexander F Rosenberg / Todd J Green / Frances E Lund / 要旨: Donor-specific antibody responses against human leukocyte antigen (HLA) proteins mismatched between transplant donors and recipients cause allograft loss, yet the structural HLA epitopes targeted by ...Donor-specific antibody responses against human leukocyte antigen (HLA) proteins mismatched between transplant donors and recipients cause allograft loss, yet the structural HLA epitopes targeted by alloreactive B cells and antibodies remain largely unresolved. We profiled the HLA-A01:01-specific B cell response in the transplanted kidney and blood of a recipient undergoing antibody-mediated rejection and identified immunodominant B cell and antibody responses that emerged early in the alloimmune response. These responses were focused on topographically exposed mismatched HLA residues located in the α helices along the peptide-binding groove of HLA-A01:01. We demonstrated that the anti-HLA-A01:01 B cell alloresponse converged and was maintained on this same immunodominant HLA subregion, which comprises only 20% of the HLA molecule, in a diverse group of HLA-A01:01-mismatched transplant recipients. Thus, the B cell and antibody alloresponses appear tightly focused on a topographically defined region on the HLA-A01:01 crown that is conserved across individuals expressing distinct constellations of self-HLA-A.
