Therefore, cells from the adaptative immunity are fundamental to restrain infection in the tissues by producing inflammatory cytokines such as IFN-γ, TNF-α, and IL-17 (Abrahamsohn and Coffman, 1996; Cardillo et al., 1996; Basso et al., 2004; Bastos et al., 2007; Miyazaki et al., 2010; Roffe et al., 2012). The gene discussed is IFNG; the disease is infection.
