IL-36Ra (aa 3-156) (mouse) (rec.) (untagged)
Method: Bone marrow cells were differentiated into bone marrow-derived dendritic cells (BMDCs) using GM-CSF (20ng/ml) for 10 days. BMDCs were cultured with or without IL-36Ra, IL-36α, IL-36β, IL-36γ, or LPS at indicated concentrations for 72 h. Cell supernatants were then harvested and IL-6 levels determined by ELISA.

IL-36Ra/IL-1F5 is a highly and a specific antagonist of the IL-1 receptor-related protein 2-mediated response to IL-36α (IL-1F6), IL-36β (IL-1F8) and IL-36γ (IL-1F9). These cytokines bind to IL-36R (IL-1Rrp2) and IL-1RAcP, activating similar intracellular signals as IL-1. IL-36Ra inhibits the production of proinflammatory cytokines, including IL-12, IL-1β, IL-6, TNF-α and IL-23 induced by IL-36 in BMDC and CD4 T cells. Skin and dendritic cells are target of the IL-36 interleukins leading to a Th1 response. Recently mutations that affect the levels and the activity of IL-36Ra have been found in patients with pustular psoriasis, leading to enhanced production of inflammatory cytokines (IL-8 in particular) by keratinocytes.
