Interleukin-17 (IL-17) is a cytokine (Aggarwal and Gurney, 2002) that is often involved in a proinflammatory response in the cytokine storm of viral infections in humans (Yuan et al., 2010; Jain et al., 2013; Reed et al., 2015) and experimental mice model (Zhang et al., 2009). Here, IL17A is linked to viral infectious disease.
