Directionality of HLA-DP permissive mismatches improves risk prediction in HCT for acute leukemia and MDS

Blood. 2024 Oct 17;144(16):1747-1751. doi: 10.1182/blood.2024024351.

Abstract

HLA-DP permissive mismatches can be assigned a direction according to their immunopeptidome divergence across core and noncore subsets. Noncore permissive graft-versus-host mismatches show significantly reduced risks of relapse without increased nonrelapse mortality compared with allele-matched pairs.
