IL-10 family

In addition to IL-10, it includes IL-19, IL-20, IL-22, IL-24 and IL-26.[1]

The IL10 family is a family of interleukins.

Some sources also include the interferons IL-28 and IL-29.[2]

IL-10 Family

Biological activity

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.[3] 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.[4]

IL-10

Interleukin 10 is produced by regulatory T lymphocytes, B cells, and monocytes. It is a homodimer that functions through the IL-10R1 and IL-10R2 receptor complexes, activating such kinases as Janus kinase and tyrosine kinase 2.[5] IL-10R2 receptor is presented in most cells, when IL-10R1 receptor is IL-10 is also an inhibitor of expressions of CD80 and CD86 by dendritic cells (DC) and antigen-presenting cells (APC),[5] and of T cells, decreasing their cytokine production, therefore, controlling their activation. IL-10 plays a big role in regulating allergies by inhibiting cytokines responsible for allergic inflammation.

IL-19

Interleukin 19 is produced mainly in monocytes, and can be found in big concentrations in patients with allergic disorders and psoriasis. IL-19 plays a big role in the CNS by regulating the inflammation process through a delayed production of it.[6]

IL-20

IL-20 - induces cheratin proliferation and Stat-3 signal transduction pathway;[6] is expressed in the CNS, myeloid cells, and keratinocytes. When IL-20 is inhibited in the CNS can stop such inflammations as acute ischemic brain injury.[6][5]

IL-22

IL-22 mediates inflammation and binds class II cytokine receptor heterodimers IL-22 RA1/CRF2-4;[7] is involved in immuno-regulatory responses

IL-24

IL-24 produced by activated monocytes and T-cells.[8]

IL-26

IL-26 is a newly discovered cytokine produced by memory T cells and monocytes. IL-26 assist with the process of human T cell transformation after their infections.[8]
