Although the IL-17 cytokine family is associated with cells of the adaptive arm of the immune system, in bacterial infections such as those caused by P. aeruginosa, innate immune cells are the first responders in secretion of IL-17, IL-21, IL-22, and IL-23 (Nieuwenhuis et al., 2002; Aujla et al., 2008; Coquet et al., 2008; Sutton et al., 2012). This evidence concerns the gene IL23A and bacterial infectious disease.
