In contrast to the identical number of ILC1s and NKs in the liver before infection (Figure 2C), we observed that 48 h after infection, the number of ILC1s was decreased (Figure 2D) and ILC1s also showed impaired secretion of IFNγ (Figures 2E,F), a cytokine that mainly functions during infection by intracellular bacteria. Here, IFNG is linked to infection.
