IL-17A Protein, Mouse (CHO)
Based on 2 publication(s) in Google Scholar
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. IL-17A Protein, Mouse (CHO) is a recombinant mouse IL-17A protein and is expressed in CHO cells. It consists of 133 amino acids (A26-A158).
- Species: Mouse
- Source: CHO
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Biological Activity
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, Mouse (CHO) is a recombinant mouse IL-17A protein and is expressed in CHO cells. It consists of 133 amino acids (A26-A158).
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 mouse IL-17A shares 63.23% amino acid sequence identity with human and 87.33% identity with rat.
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].
Recombinant mouse interleukin 17 (rmIL-17) (0.1 or 0.9 μg/rat/day; nasally; 6 days) shows increased infiltration of inflammatory cells into the sciatic nerve, more severe demyelination, augmented proliferation of regional lymph node cells, and increased serum levels of tumor necrosis factor-α in chronic experimental autoimmune neuritis (EAN) induced Lewis rats[5].
rmIL-17A (625 ng/mouse; i.t.; once) dramatically synergizes TNF-alpha induced neutrophil accumulation in C57BL/6 mice[6].
1.Full biological activity determined by its ability to induce IL-1a, IL-4 and IL-6 production by primary mouse splenocytes.
2. Measured by its ability to induce IL-6 secretion by NIH-3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 1-3 ng/mL.
