Interleukin-1 family member 5 (IL-1F5); also known as interleukin 36 receptor antagonist (IL36RA); is a member of the interleukin 1 cytokine family. This cytokine was shown to specifically inhibit the activation of NF-kappaB induced by interleukin 1 family; member 6 (IL1F6). IL-1F5 is a highly and a specific antagonist of the IL-1 receptor-related protein 2-mediated response to interleukin 1 family member 9 (IL1F9). IL-1F5 could constitute part of an independent signaling system analogous to interleukin-1 alpha (IL-1A); beta (IL-1B) receptor agonist and interleukin-1 receptor type I (IL-1R1); which is present in epithelial barriers and takes part in local inflammatory response. It has been proved that IL-1F5 induces IL-4 mRNA and protein expression in glia in vitro and enhances hippocampal expression of IL-4 following intracerebroventricular injection. The inhibitory effect of IL-1F5 on LPS-induced IL-1β is attenuated in cells from IL-4-defective mice. Experiment results suggest that IL-1F5 mediates anti-inflammatory effects through its ability to induce IL-4 production and that this is a consequence of its interaction with the orphan receptor; single Ig IL-1R-related molecule (SIGIRR)/TIR8; as the effects were not observed in SIGIRR−/− mice. In contrast to its effects in brain tissue; IL-1F5 did not attenuate LPS-induced changes; or up-regulated IL-4 in macrophages or dendritic cells; suggesting that the effect is confined to the brain.
