FMT could increase the killing efficacy of CD8⁺ T cells in intestinal tissues by regulating cytokines and chemokines. Differences in IFN-γ⁺CD8⁺ T cells (A) in intestinal tissues determined by flow cytometry. PCR assay detected differential mRNA expression of granzyme B (B), TNF-α (C), IFN-γ (D), CXCL9 (E) and CXCL10 (F) in mouse intestinal tissues. Data are represented as means ± SDs, n = 5. One-way ANOVA was used for comparisons between multiple groups. ns, not significant, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
