Killer immunoglobulin-like receptor (KIR) and KIR-ligand (KIRL) interactions play an important role in natural killer cell-mediated effects after hematopoietic stem cell transplantation (HCT). Previous work has shown that accounting for known KIR-KIRL interactions may identify donors with optimal NK cell-mediated alloreactivity in the adult transplant setting. Pediatric acute leukemia patients were retrospectively analyzed and KIR-KIRL combinations and maximal inhibitory KIR ligand (IM-KIR) sco...
