Tregs discovery
WebFOXP3 (forkhead box P3), also known as scurfin, is a protein involved in immune system responses. A member of the FOX protein family, FOXP3 appears to function as a master regulator of the regulatory pathway in the development and function of regulatory T cells. Regulatory T cells generally turn the immune response down. In cancer, an excess of … WebFeb 8, 2024 · T regulatory cells, or Tregs, are a distinct population of T cells that suppress immune responses. As such, Tregs prevent self-directed immunity, or autoimmunity, regulate immunity during infection, resolve tissue inflammation, and mediate tissue repair, among other functions. Their immunosuppressive capabilities, however, can sometimes …

WebBecause their major role is to ensure that the immune system is not over reactive, Tregs have been the focus of multiple research studies including those investigating transplantation tolerance, autoimmunity and cancer treatment. On their surface Tregs constitutively express CD25, a high affinity receptor for the cytokine interleukin-2 (IL-2). WebFoxP3 (forkhead box P3) is an intracellular transcription factor. It is a specific marker for Tregs. It was discovered in mice during research of lymphoproliferative diseases and was also observed in the spontaneous genetic mouse mutant “scurfy.” In humans, it was identified during efforts to understand the fatal autoimmune disease IPEX

WebJul 30, 2024 · Tregs belong to CD4+ T cells family, that include Th1, Th2, Th17,Th9 and Th22. The importance of Tregs came to light, when it was discovered it plays a role in tolerance of transplanted organs[4]. Molecular investigations aiming to discoverer T reg differentiation and function increased dramatically following Tregs discovery. WebInvestigating the migration characteristics of Treg cells by using the endothelial cell-based shear-stress flow assay that resembles the intravascular blood flow system found that both FoxP3-expressing Tregs and anergic T cells generated by blockage of costimulation factors, CD80 and CD86, exhibited a significantly decreased adhesion to endothelial cells as …
