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.
Cytokines have been shown to be involved in autocrine, paracrine and endocrine signaling as immunomodulating agents. Cytokines include chemokines, interferons, interleukins, lymphokines, and tumour necrosis factors, but generally not hormones or growth factors (despite some overlap in the terminology) [citation needed].
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.
The IL-10 family is a family of interleukins. In addition to IL-10, it includes IL-19, IL-20, IL-22, IL-24 and IL-26. [1] Some sources also include the interferons IL-28 and IL-29. [2] The IL-10 family are helical cytokines categorized based on their specific similarities and can be classified as class 2 cytokines. [3]
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 ]
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] [46] Common cytokines include interleukins that are responsible for communication between white blood cells; chemokines that promote chemotaxis; and interferons that have anti-viral effects, such as shutting down protein synthesis in the host cell. [47] Growth factors and cytotoxic factors may also be released. These cytokines and other ...
Interleukin 10 (IL-10), also known as human cytokine synthesis inhibitory factor (CSIF), is an anti-inflammatory cytokine. In humans, interleukin 10 is encoded by the IL10 gene. [ 5 ] IL-10 signals through a receptor complex consisting of two IL-10 receptor-1 and two IL-10 receptor-2 proteins. [ 6 ]
