Antibiotic treatment attenuates the colitis in CD4-Cre+/TgMettl14FL/FL conditional knockout mice. The CD4-Cre+/TgMettl14FL/FL conditional knockout mice were treated with ciprofloxacin + metronidazole for 3 weeks and compared with untreated mice. (A) Colonic weight-to-length ratio, (B) hematoxylin and eosin stain of colon, and (C) relative expression of Th1 cytokine IFNγ/TNFα and Th17 cytokine IL-17a/IL-17c. Log2 scale was used on the y-axis. (D) Colonic weight-to-length ratio of mice in specific pathogen–free (SPF) facility compared with germ-free facility. (E) Relative expression of Th1 cytokine IFNγ/TNFα and Th17 cytokine IL-17a/IL-17c of mice in germ-free facility. WT indicates wild-type littermate control. KO indicates CD4-Cre+/TgMettl14FL/FL conditional knockout. Data are represented as mean ± SD; n = 7–9 mice per group. Combined data from 2 independent experiments shown.
