Figure 5. Selective loss of ILC3s or ILC3 effector molecules reveals their limited role in recovery following acute C. difficile infection.
(A) Weight loss and (B) survival of RorcHET or Rorc KO mice following CDI. Combination of 3 independent experiments (n=10-11). (C-G) C57BL/6 and Il22−/− mice were infected with C. difficile spores and assessed for (C) weight loss and (D) survival. Weight loss curve is representative of 4 independent experiments. Survival curve is a combination of 4 experiments (n=21-22). (E) C. difficile burden and (F) toxin levels in the cecal content at day 3 post-infection. (G) Fold induction of Reg3g, Ifng, and Nos2 in the colon of day 3 infected C57BL/6 and Il22−/− mice relative to uninfected C57BL/6 mice and normalized to Hprt (n=7-8). (H) Weight loss and (I) survival of Rag1−/− or Rag1−/− mice treated with anti-IL-17a neutralizing antibody (n=8). (J) Survival of Rag1−/− or Rag.Il17 dKO− mice (n=7-9). *p<0.05, **p<0.01. Data shown are mean ± SEM. See also Figure S5.
