When addressing role of IL-17A in Staphylococcal infections, similar observations (induction upon infection) have been previously reported in S. aureus FRI (Rochford et al., 2016) and there is evidence that TH17 responses are important for S. aureus clearance in other infection models (Montgomery et al., 2014; Vidlak and Kielian, 2012; Maher et al., 2013; Yu et al., 2018), or in reducing S. aureus nasal carriage (Archer et al., 2016). The gene discussed is IL17A; the disease is infection.
