Extra Details:: Interleukin-17A (IL-17A), also known as CTLA-8, is a 15-20kD glycosylated cytokine that plays an important role in anti-microbial and chronic inflammation. The six IL-17 cytokines (IL-17A-F) are encoded by separate genes but adopt a conserved cystine knot fold (1, 2). Mature mouse IL-17A shares 61% and 89% amino acid sequence identity with human and rat IL-17A, respectively (3, 4). IL-17A is secreted by Th17 cells, gamma/delta T cells, iNKT cells, NK cells, LTi cells, neutrophils, and intestinal Paneth cells (2). It forms disulfidelinked homodimers as well as disulfide-linked heterodimers with IL-17F (5, 6). IL-17A exerts its effects through the transmembrane IL-17 RA in complex with IL-17 RC or IL-17 RD (7, 8). Both IL-17 RA and IL-17 RC are required for responsiveness to heterodimeric IL-17A/F (7). IL-17A promotes protective mucosal and epidermal inflammation in response to microbial infection (9-12). It induces chemokine production, neutrophil influx, and the production of antibacterial peptides (9-11). IL-17A/F likewise induces neutrophil migration, but IL-17F does not (11). IL-17A additionally enhances the production of inflammatory mediators by rheumatoid synovial fibroblasts and contributes to TNF-alpha induced shock (Fossiez, 14). In contrast, it can protect against the progression of colitis by limiting chronic inflammation (12). IL-17A encourages the formation of autoreactive germinal centers and exacerbates the onset and progression of experimental models of autoimmunity (15, 16). IL-17A has been shown to exert either tumorigenic or anti-tumor effects (17, 18). Source: Recombinant protein corresponding to aa26-158 from mouse IL-17A, CHO-derived.
