Interleukin-2 (IL-2) is an interleukin, ... Put shortly the function of IL-2 is to stimulate the growth of helper, cytotoxic and regulatory T cells. IL-2 receptor
A related suggestion with regard to interleukin 2 is that activated regulatory T cells take up interleukin 2 so avidly that they deprive effector T cells of sufficient to avoid apoptosis. [ 18 ] A major mechanism of suppression by regulatory T cells is through the prevention of co-stimulation through CD28 on effector T cells by the action of ...
IL-2 binds to the IL-2 receptor, which has three forms, generated by different combinations of three different proteins, often referred to as "chains": α (alpha) (also called IL-2Rα, CD25, or Tac antigen), β (beta) (also called IL-2Rβ, or CD122), and γ (gamma) (also called IL-2Rγ, γ c, common gamma chain, or CD132); these subunits are also parts of receptors for other cytokines.
The interleukin-2 receptor alpha chain (also called Tac antigen, P55, and mainly CD25) is a protein involved in the assembly of the high-affinity interleukin-2 receptor, consisting of alpha (IL2RA), beta and the common gamma chain ().
Interleukin 9 (IL-9) [30] is a cytokine that supports IL-2 independent and IL-4 independent growth of helper T cells. Early studies had indicated that Interleukin 9 and 7 seem to be evolutionary related [ 31 ] and Pfam, InterPro and PROSITE entries exist for interleukin 7/interleukin 9 family.
Tyrosine-protein kinase ITK/TSK also known as interleukin-2-inducible T-cell kinase or simply ITK, is a protein that in humans is encoded by the ITK gene. [5] ITK is a member of the TEC family of kinases and is highly expressed in T cells .
Interleukin 4 acts on helper T cells to promote the production of T h 2 cytokines (including itself; it is auto-regulatory), while interleukin 10 (IL-10) inhibits a variety of cytokines including interleukin 2 and IFNγ in helper T cells and IL-12 in dendritic cells and macrophages. The combined action of these two cytokines suggests that once ...
The interleukin 2 receptor, which is involved in T cell-mediated immune responses, is present in 3 forms with respect to ability to bind interleukin 2. The low affinity form is a monomer of the alpha subunit (also called CD25) and is not involved in signal transduction. The intermediate affinity form consists of a gamma/beta subunit heterodimer ...
