IL-17C 蛋白, Human (sf9, Fc)

IL-17C is an early response cytokine in the defense against bacterial pathogens and upregulates the expression of a variety of antimicrobial peptides. IL-17C stimulates the release of cytokines and is implicated in autoimmune disorders and bacterial infections^[1]. IL-17C Protein, Human (sf9, Fc) is a recombinant human IL-17C protein with hFc tag at the C-terminus and is expressed in Sf9 insect cells. It consists of 197 amino acids (M1-V197).

白细胞介素-17C (IL-17C) 属于 IL-17 细胞因子家族。IL-17C 主要由上皮细胞表达。
人和小鼠IL-17C序列一致性为76.68%。
IL-17C与其功能受体结合，该受体是由IL-17RA和IL-17RE形成的异二聚体。TLR2、TLR3和TLR5上调粘膜表面IL-17C的表达。IL-17C 的表达也受细胞因子（TNF-α、IL-1β 和 IL-17A）的调节。IL-17C 是防御细菌病原体的早期反应细胞因子，并上调多种抗菌肽的表达，包括人 β-防御素 2 (hBD2)、脂质运载蛋白 2 (LCN2) 和颗粒酶 B。IL-17C 还刺激细胞因子（IL-1β、TNF-α 和 IL-6）的释放。
IL-17C 与自身免疫性疾病和细菌感染有关^[1]。

IL-17C is abundantly expressed in inflamed skin^[2].
IL-17C (1 ng/mL; 16 h) potentiates TNF-α effects and mediates immune cell recruitment by induction of chemokines in keratinocytes^[2].
IL-17C (2 ng/mL; 24 h) and TNF-α (2 ng/mL) induce characteristic psoriasis-related transcriptome genes in both additive and synergistic manners. IL-17C (6 h) increases mRNA expression of TNF-α and IL-6^[3].
