Intriguingly however, we saw no change in the Ki-67 expression of LTi-like ILC3 at day 6 of C. rodentium infection in the colon (Figs. 2H and 2I; Supplementary Figs. S3C and S3D), despite exhibiting a robust increase in IL-22 production in response to infection as expected (Figs. 2J and 2K; Supplementary Figs. S3E and S3F). Here, IL22 is linked to infection.
