Interleukin 3 (IL3) is a cytokine that regulates hematopoiesis by controlling the production, differentiation and function of granulocytes and macrophages. [ 15 ] [ 16 ] The protein, which exists in vivo as a monomer, is produced in activated T cells and mast cells, [ 15 ] [ 16 ] and is activated by the cleavage of an N-terminal signal sequence.
Because cytokines are characterised by considerable redundancy and pleiotropism, such distinctions, allowing for exceptions, are obsolete. The term interleukin was initially used by researchers for those cytokines whose presumed targets are principally white blood cells (leukocytes). It is now used largely for designation of newer cytokine ...
An inflammatory cytokine is a type of cytokine (a signaling molecule) that is secreted from immune cells and certain other cell types that promotes inflammation. Inflammatory cytokines are predominantly produced by T helper cells (T h) and macrophages and involved in the upregulation of inflammatory reactions. [1]
The IL-10 family is one of the important types of cytokines, that can stop the inflammation. In general. these cytokines have a helical structure of homodimers. [4] The difference that the members of IL-10 family have between each other is that they have various receptor-binding residues, which help with interaction with specific cytokine receptors. [5]
The Type 2 response promotes its own profile using two different cytokines. 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 ...
This cytokine may bind or may itself be a ligand of the IL-18 receptor (IL18R1 / IL-1Rrp). It binds to the interleukin 18 binding protein (IL18BP), forming a complex with the beta subunit of the IL-18 receptor (IL-1F4), thereby inhibiting its activity. 5 alternative transcripts encoding different IL-37 isoforms have been described. [45]
Interleukin 17 family (IL17 family) is a family of pro-inflammatory cystine knot cytokines. [2] They are produced by a group of T helper cell known as T helper 17 cell in response to their stimulation with IL-23. Originally, Th17 was identified in 1993 by Rouvier et al. who isolated IL17A transcript from a rodent T-cell hybridoma. [3]
Interleukin-2 (IL-2) is an interleukin, which is a type of cytokine signaling molecule forming part of the immune system. It is a 15.5–16 kDa protein [ 5 ] that regulates the activities of white blood cells (leukocytes, often lymphocytes ) that are responsible for immunity.
