Delayed T-cell recruitment during Citrobacter rodentium infection after nociceptor ablation. Colonic tissue sections were assessed for recruitment of T cells (CD3⁺ DAPI⁺) in vehicle ± C rodentium and resiniferatoxin (RTX) ± C rodentium-treated mice and quantified. Scale bar, 50 µm. Data are presented as mean ± standard error of the mean: *, P < .05 and ***, P < .001 compared with uninfected mice; #, P < .05 and ###, P < .001 compared with vehicle C rodentium-infected mice; one-way analysis of variance with Tukey posttest, with 8–12 animals per group. DAPI, 4’,6-diamidino-2-phenylindole; LB, Luria-Bertani; p.i., postinfection.
