Quatrini et al. studied infection with murine cytomegalovirus (MCMV) in mice lacking GR expression in NK and ILC-1 cells (GRNcr1-iCre mice) and found that IFN-γ production two days after infection was increased in the spleen, but not in the liver (endogenous GCs are released within 36 h in this infection model) [12]. Here, IFNG is linked to infection.
