Virus-specific IL-17-producing CD4+ T cells have also been detected in mice following herpes simplex virus (HSV) [114], Theiler's murine encephalomyelitis virus (TEMV) [115], and vaccinia virus (VV) [116] infection, among others [20], albeit at a lower magnitude than the prototypical antiviral TH1 response. The gene discussed is IL17A; the disease is infection.
