Interleukin-10 (IL-10 or IL10), also known as human cytokine synthesis inhibitory factor (CSIF), is an anti-inflammatory cytokine. In humans IL-10 is encoded by the IL10 gene.[1]
This cytokine is produced primarily by monocytes and to a lesser extent by lymphocytes. This cytokine has pleiotropic effects in immunoregulation and inflammation. It down-regulates the expression of Th1 cytokines, MHC class II antigens, and costimulatory molecules on macrophages. It also enhances B cell survival, proliferation, and antibody production. This cytokine can block NF-κB activity, and is involved in the regulation of the JAK-STAT signaling pathway. Knockout studies in mice suggested the function of this cytokine as an essential immunoregulator in the intestinal tract.[2] and indeed patients with Crohn's disease react favorably towards treatment with bacteria producing recombinant interleukin 10, showing the importance of interleukin 10 for counteracting excessive immunity in the human body.[3]
A study in mice has shown that interleukin-10 is also produced by mast cells, counteracting the inflammatory effect that these cells have at the site of an allergic reaction.[4]
Function
It is capable of inhibiting synthesis of pro-inflammatory cytokines like IFN-γ, IL-2, IL-3, TNFα and GM-CSF made by cells such as macrophages and the Type 1 T helper cells.
IL-10 also displays potent abilities to suppress the antigen presentation capacity of antigen presenting cells.
However, it is also stimulatory towards certain T cells, mast cells and stimulates B cell maturation and antibody production.
Expression
It is mainly expressed in monocytes and Type 2 T helper cells (TH2), mast cells, CD4+CD25+Foxp3+ regulatory T cells, and also in a certain subset of activated T cells and B cells.
It is released by cytotoxic T-cells to inhibit the actions of NK cells during the immune response to viral infection.
Gene and protein structure
In humans, the IL-10 gene is located in chromosome 1 and consists of 5 exons.[1]
The IL-10 protein is a homodimer . Each subunit is 178 amino acids long.[5]
Interactions
Interleukin 10 has been shown to interact with Interleukin 10 receptor, alpha subunit.[6][7][8][9][10]
