IL-17C is a member of the IL-17 cytokine family produced by epithelial cells, and is induced in response to bacterial (Ramirez-Carrozzi et al., 2011; Song et al., 2011; Pfeifer et al., 2013; Roth et al., 2014; Wolf et al., 2016; Steck et al., 2019; Jeon et al., 2020), viral (Ioannidis et al., 2012; Peng et al., 2017), or fungal infections (Conti et al., 2015; Huang et al., 2016). This evidence concerns the gene IL17C and fungal infectious disease.
