نقش ترکیب KIR-HLA در پیوند سلول‌های بنیادی خونساز
Background : Allogeneic hematopoietic stem cells transplantation (HSCT) is a valuable therapy for refractory acute leukemias, leukemias with a high risk for relapse, myelodysplastic syndromes, and chronic myeloid leukemia. HSCT outcome is dependent on several factors, including the stage of disease, degree of human leukocyte antigen (HLA) identity between donor and recipient, conditioning regim...

A potential factor influencing hematopoietic stem cells transplantation (HSCT) outcome is the presence of donor-derived alloreactive natural killer (NK) cells. This retrospective analysis studied the impact of NK alloreactivity based on the missing KIR ligand, for acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) patients undergoing non-T-cell depleted HLA-identical sibling HS...
متن کاملFemale donors contribute to a selective graft-versus-leukemia effect in male recipients of HLA-matched, related hematopoietic stem cell transplants.
Male recipients of transplants from female (F-->M) hematopoietic stem cell donors represent a special group in whom donor T cells that are specific for recipient minor histocompatibility antigens encoded by Y-chromosome genes may contribute to a graft-versus-leukemia (GVL) effect and to graft-versus-host disease (GVHD). We examined the contribution of donor/patient sex to the risk for relapse a...
متن کاملHLA-DPB1 matching status has significant implications for recipients of unrelated donor stem cell transplants.
Studies in unrelated donor (UD) hematopoietic stem cell transplantations (HSCT) show an effect of the matching status of HLA-DPB1 on complications. We analyzed 423 UD-HSCT pairs. Most protocols included T-cell depletion (TCD). All pairs had high-resolution tissue typing performed for 6 HLA loci. Two hundred eighty-two pairs were matched at 10 of 10 alleles (29% were DPB1 matched). In 141 HLA-mi...

متن کاملReduction of Relapse after Unrelated Donor Stem Cell Transplantation by KIR-Based Graft Selection
Besides donor T cells, natural killer (NK) cells are considered to have a major role in preventing relapse after allogeneic hematopoietic stem cell transplantation (HSCT). After T-cell-depleted haploidentical HSCT, a strong NK alloreactivity has been described. These effects have been attributed to killer-cell immunoglobulin-like receptors (KIR). Abundant reports suggest a major role of KIR not...
