General Information
IL-1F5, F6, F8 and F9 are new members of the family of IL-1 (IL-1α/β, IL-18, IL-33). IL-1F6, IL-1F8 and IL-1F9 activate the NF-κB and MAPK pathways through the IL-Rrp2 and IL-1RAcP receptor complex leading to the production of IL-6 and IL-8. Agonistic activation of the IL-1F6, F8 and F9 is counterbalanced by the inhibitory activity of IL-1F5. These interleukins are mainly expressed in skin keratinocytes and internal epithelial tissues exposed to pathogenic bacteria suggesting a role in immune signalling and inflammation. IL-F5, F6 and F9 as well as the receptor IL-1Rrp2 are increased in psoriasis.
