Interleukin 21 (IL-21) is a protein that in humans is encoded by the IL21 gene. [5] [6] [7]Interleukin-21 is a cytokine that has potent regulatory effects on cells of the immune system, including natural killer (NK) cells and cytotoxic T cells that can destroy virally infected or cancerous cells.
3.3 T cell anergy and exhaustion. ... Download as PDF; ... Bcl6 and IL-21. Tfh cells express high levels of NFATc1 and especially NFATc2 and NFAT2/αA which suggest ...
Interleukin 10 (IL-10) is a protein that inhibits the synthesis of a number of cytokines, including IFN-gamma, IL-2, IL-3, TNF, and GM-CSF produced by activated macrophages and by helper T cells. In structure, IL-10 is a protein of about 160 amino acids that contains four conserved cysteines involved in disulphide bonds. [ 33 ]
The severity of GvHD is highly variable and is influenced by the amount of native cells present in the environment along with other regulatory T cells, T H 1, T H 2, or T H 17 phenotypes. [10] Both CD4 + and CD8 IL-17 producing T cells have been shown to cause aTH1, causing tissue inflammation and resulting in severe GVHD. [11]
Their key effector cytokine is IL-10. Their main effector cells are NK cells as well as CD8 T cells, IgG B cells, and IL-10 CD4 T cells. The key THαβ transcription factors are STAT1 and STAT3 as well as IRFs. IL-10 from CD4 T cells activate NK cells' ADCC to apoptose virus-infected cells and to induce host as well as viral DNA fragmentation ...
Interleukin 21 receptor is a type I cytokine receptor. IL21R is its human gene. [5]The protein encoded by this gene is a cytokine receptor for interleukin 21 (IL21). It belongs to the type I cytokine receptors, and has been shown to form a heterodimeric receptor complex with the common gamma chain (γc), a receptor subunit also shared by the receptors for interleukin 2 (IL2), interleukin 7 ...

T H 2 cells which produce IL-4, IL-5, and IL-13. A third category called T helper 17 cells (T H 17) were also discovered which are named after their secretion of Interleukin 17. CD8 + cytotoxic T-cells may also be categorized as: [5] T c 1 cells, T c 2 cells. Similarly to CD4 + T H cells, a third category called T C 17 were discovered that also ...
