Regulatory T cells and natural killer T cells for modulation of GVHD following allogeneic hematopoietic cell transplantation.
Alloreactivity of donor lymphocytes leads to graft-versus-host disease (GVHD) contributing to significant morbidity and mortality following allogeneic hematopoietic cell transplantation (HCT). Within the past decade, significant progress has been made in elucidating the mechanisms underlying the immunologic dysregulation characteristic of GVHD. The recent discoveries of different cell subpopula...
متن کاملAltered regulatory T cell homeostasis in patients with CD4+ lymphopenia following allogeneic hematopoietic stem cell transplantation.
CD4+CD25+Foxp3+ Tregs have an indispensable role in the maintenance of tolerance after allogeneic HSC transplantation (HSCT). Patients with chronic graft-versus-host disease (GVHD) have fewer circulating Tregs, but the mechanisms that lead to this deficiency of Tregs after HSCT are not known. Here, we analyzed reconstitution of Tregs and conventional CD4+ T cells (Tcons) in patients who underwe...
متن کاملT-Cell Metabolism in Hematopoietic Cell Transplantation
Metabolism, including catabolism and anabolism, is a basic cellular process necessary for cell survival. T lymphocytes have a distinct metabolism that can determine both fate and function. T-cell activation depends on glycolysis to obtain materials and energy for proliferation and effector function. Importantly, T cells utilize different metabolic processes under different conditions and diseas...
متن کاملPediatric Hematopoietic Stem Cell Transplantation
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 کاملAFM detection of biophysical characteristics of specific regulatory T Cells after allogeneic hematopoietic stem cell transplantation
Background: Based on the dynamics of antigen recognition from T cell receptor complex and T cell activation, different function of T cells may present different morphology feature, at least at molecular level. Regulatory T (Treg) cells play a critic role in regulation the onset of graft versus host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Little is kn...
