IL17: A driver of autoimmune disease and inflammation

Sino Biological has developed bioactive recombinant IL17 cytokines from various species, such as human, mouse, cynomolgus, rabbit, marmoset, rhesus, and canine.


Interleukin-17 (IL17/IL17A) is a pro-inflammatory cytokine produced by T helper 17 (Th17) cells. Because of its crucial roles in immune regulation, IL17 is now a target for an array of therapeutic monoclonal antibodies and inhibitors to treat various inflammatory diseases and cancer.

IL17 belongs to a distinct cytokine family with five additional members: IL17B, IL17C, IL17D, IL17E/IL25, and IL17F. IL17 shares the most sequence homology with IL17F. IL17 and IL17F form homodimers and heterodimers (IL17A & IL17F) to signal through the receptor complex composed of the subunits of IL17RA and IL17RC. Both IL17 and IL17F are major contributors in recruiting neutrophils to sites of inflammation. The IL17 and IL17F signaling can induce the production of cytokines (IL-1β, TNFα, G-CSF, IL-6, etc.), chemokines (MCP-1/CCL2, CXCL1, CXCL2, CCL20, etc.), inflammatory effectors, and antimicrobial proteins. The IL17RA subunit is used by at least two other ligands, IL17C and IL17E. Other members of the IL17 Receptor family include IL17RB, IL17RC, IL17RD, and IL17RE. Sino Biological has developed a panel of high-quality recombinant IL17 family cytokines and receptor proteins as well as antibodies to support the study of this cytokine family.
