The IL-23/IL-17 axis is essential in the resolution of infection by Candida albicans [232,233], Staphylococcus aureus [234], and Bordetella pertussis [235], and IL-23-induced IL-22 production is involved in the clearance of lymphocytic choriomeningitis virus (LCMV) infection [236]. The gene discussed is IL37; the disease is infection.
