Killer cell immunoglobulin like receptor (KIR) 3DS1 is one of the most important activating receptors and some studies revealed that KIR3DS1 combined with HLA ligand was not related to acute myeloid leukemia (AML), but rare data was reported in Chinese population.
We investigated the influence of killer cell immunoglobulin-like receptor (KIR) genes, based on the genotypes of inhibitory or activating KIR, in stem cell recipients with acute myelogenous leukemia and their human leukocyte antigen-matched sibling donors on acute graft-versus host disease (GVHD) after hematopoietic stem cell transplantation.
