  2. Regulatory T cell - Wikipedia

    en.wikipedia.org/wiki/Regulatory_T_cell

    The regulatory T cells (Tregs / ˈ t iː r ɛ ɡ / or T reg cells), formerly known as suppressor T cells, are a subpopulation of T cells that modulate the immune system, maintain tolerance to self-antigens, and prevent autoimmune disease. T reg cells are immunosuppressive and generally suppress or downregulate induction and proliferation of ...

  3. Suppressor-inducer T cell - Wikipedia

    en.wikipedia.org/wiki/Suppressor-inducer_T_cell

    Suppressor-inducer T cells are a specific subset of CD4 + T helper cells that "induce" CD8 + cytotoxic T cells to become "suppressor" cells. [1] Suppressor T cells are also known as CD25 + – Foxp3 + regulatory T cells (nTregs), and reduce inflammation .

  4. T cell - Wikipedia

    en.wikipedia.org/wiki/T_cell

    T cells are grouped into a series of subsets based on their function. CD4 and CD8 T cells are selected in the thymus, but undergo further differentiation in the periphery to specialized cells which have different functions. T cell subsets were initially defined by function, but also have associated gene or protein expression patterns.

  5. Myeloid-derived suppressor cell - Wikipedia

    en.wikipedia.org/.../Myeloid-derived_suppressor_cell

    MDSC activity was originally described as suppressors of T cells, in particular of CD8+ T-cell responses. The spectrum of action of MDSC activity also encompasses NK cells, dendritic cells and macrophages. Suppressor activity of MDSC is determined by their ability to inhibit the effector function of lymphocytes. Inhibition can be caused by ...

  6. Type 1 regulatory T cell - Wikipedia

    en.wikipedia.org/wiki/Type_1_regulatory_T_cell

    Cell to cell contact: Type 1 regulatory T cells poses inhibitory receptor CTLA-4 through which they exert suppressor function. [12] Metabolic disruption: Tr1 cells can express ectoenzymes CD39 and CD73 and are suspected of generating adenosine which suppresses effector T cell proliferation and their cytokine production in vitro. [13] Cytolitic ...

  8. Infectious tolerance - Wikipedia

    en.wikipedia.org/wiki/Infectious_tolerance

    Gershon and Kondo discovered that T cells can not only amplify but also diminish immune responses. [5] The T cell population causing this down-regulation was called suppressor T cells and was intensively studied for the following years (nowadays they are called regulatory T cells and are again a very attractive for research). [6]

  9. Immune checkpoint - Wikipedia

    ICOS: This molecule, short for Inducible T-cell costimulator, and also called CD278, is expressed on activated T cells. Its ligand is ICOSL, expressed mainly on B cells and dendritic cells. The molecule seems to be important in T cell effector function. [26] The American biotechnology company Jounce Therapeutics is developing an ICOS agonist.
