The Advanced HLA Typing Strategies for Hematopoietic Stem Cell Transplantation
نویسندگان
چکیده
The occurrence of graft rejection and/or graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is largely depended on whether the re‐ cipient and the donor have matched HLA types. Under normal circumstances, the individu‐ al with completely matched HLA antigens can be the donor. However, due to the high level of HLA polymorphism, the major obstacle in the allogeneic hematopoietic stem cell trans‐ plantation is to find a donor with HLA antigens that are a perfect match. This can prove to be quite problematic.

Mesenchymal stem cells as a reference cell for HLA-typing
Introduction: Recognition of human leukocyte antigens (HLA) is of importance for hematopoietic stem cell transplantation. Any HLA-mismatches between the donor and recipient can cause graft rejection or other complications. In HLA-typing experiments, usage of HLA-known reference cells accompany with HLA-unknown samples is obligatory. Some international centers represent these cells with high e...
متن کاملCharting improvements in US registry HLA typing ambiguity using a typing resolution score.
Unrelated stem cell registries have been collecting HLA typing of volunteer bone marrow donors for over 25years. Donor selection for hematopoietic stem cell transplantation is based primarily on matching the alleles of donors and patients at five polymorphic HLA loci. As HLA typing technologies have continually advanced since the beginnings of stem cell transplantation, registries have accrued ...

Background: Allogenic hematopoietic stem cell transplantation (HSCT) is a strategy used for treatment of different malignant diseases. However, success of allo-HSCT can be hampered by graft-versus-host-disease (GVHD). Natural killer (NK) cells may play an important role in activating antigen presenting cells and subsequent activation of T cells. The main purpose of this study was the evaluation...

The introduction and evolution of hematopoietic stem cell transplantation (HSCT) could be traced back to 1950s, to the studies on interactions among irradiation, covering spleen and bone marrow from it and injection of bone marrow cells. Today, HSCT is considered a well-established, effective and promising means of therapy for various malignant and non-malignant medical conditions, both in chil...
متن کاملHigh-resolution HLA matching in hematopoietic stem cell transplantation: a retrospective collaborative analysis.
To validate current donor selection strategies based on previous international studies, we retrospectively analyzed 2646 transplantations performed for hematologic malignancies in 28 German transplant centers. Donors and recipients were high resolution typed for HLA-A, -B, -C, -DRB1, and -DQB1. The highest mortality in overall survival analysis was seen for HLA-A, -B, and DRB1 mismatches. HLA-D...
