WebFeb 8, 2024 · February 08, 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.
WebT follicular regulatory cells have been described in the literature mainly as suppressors of the GC reaction and the Ab response, repressing the proliferation of Tfh cells and GC B cells, and limiting the generation of Ab-secreting cells and overall Ab responses. WebT follicular helper cells (Tfh) are a specialized subset of CD4 + T cells that were first identified in the human tonsil. They play a critical role in protective immunity helping B cells produce antibody against foreign pathogens. …
