IL-10 binds to a type II cytokine receptor, with Jak1 and Tyk2, Janus family kinases, which induce STAT3 signaling molecule.

IL-10 effects

Macrophages, dendritic cells: inhibition of IL-12 production and expression of costimulators and class II MHC molecules

IL-10 has numerous functions:

- Inhibits eosinophil survival
- Inhibits IL-4 induced IgE synthesis
- Enhances IgG4 isotype switching
- Main inhibitory cytokine produced by T-reg cells in SCIT


In normal volunteers, IL-10 decreases CD4+ and CD8+ T cells, T-cell proliferation and endotoxin-driven TNF and IL-1beta production.
