IL-17A Protein, Rabbit

IL-17A is a homodimeric cytokine and plays a critical role in host defense mechanisms against many bacterial and fungal pathogens as well as allergic and autoimmune responses. IL-17A induces the production of antimicrobial peptides, cytokines, chemokines, and matrix metalloproteinases^[1][2]. IL-17A Protein, Rabbit is a recombinant rabbit IL-17A protein and is expressed in E. coli. It consists of 130 amino acids (G24-A153).

Interleukin-17A (IL-17A), also known as CTLA-8, belongs to the IL-17 cytokine family. IL-17A is expressed in memory Th17 cells and is a product of memory CD4⁺ T cells. IL-17A is also produced by a wide variety of immune cells, including CD8⁺ T cells, γδT cells, natural killer T (NKT) cells, monocytes, and neutrophils^[1][2][3].
The rhesus macaque IL-17A shares 76.47% amino acid sequence identity with human and 68.63% identity with mouse.
IL-17A plays a critical role in host defense mechanisms against many bacterial and fungal pathogens as well as allergic and autoimmune responses. IL-17A induces the production of antimicrobial peptides (defensins and S100 proteins), cytokines (IL-6, G-CSF, and GM-CSF), chemokines (CXCL1, CXCL5, IL-8, CCL2, and CCL7), and matrix metalloproteinases (MMP1, MMP3, and MMP13). IL-17A is detrimental in viral infection through promoting neutrophilic inflammation. IL-17A is a homodimeric cytokine and shares similar biological activities with IL-17F. IL-17A binds to IL-17RA with high affinity, and IL-17RA is required for the biological activity of IL-17A. In tumorigenesis, IL-17A recruits myeloid derived suppressor cells (MDSCs) to dampen anti-tumor immunity. IL-17A also enhances tumor growth in vivo through the induction of IL-6^[1][2].
IL-17A can be used for the research of autoimmune diseases, infection and cancer^[1][4].

Measured by its ability to induce IL-6 secretion by NIH-3T3 mouse embryonic fibroblast cells. The ED₅₀ this effect is 1.432 ng/mL, corresponding to a specific activity is 6.98×10⁵ U/mg.
