The immunomodulatory effects of Sb (105 and 107 CFU/ml) on colons of DSS-induced colitis mice. (a) Immunofluorescence staining analysis of F4/80-positive macrophages (red) in colon mucosa. (Magnification: ×200; Scale bar: 20 μm). DAPI was used for nuclear counterstaining (blue). (b) Statistics of F4/80. . (c) Immunofluorescence analysis of Ly6G positive neutrophils (red) in colon mucosa. (Magnification: ×200; Scale bar: 20 μm). DAPI was used for nuclear counterstaining (blue). (d) Statistics of Ly6G. . (e–g) The CD4+ and CD8+ T cell percentages were detected by flow cytometry. . Values are presented as . and compared with control group. , and compared with the other groups. Sb: S. boulardii.
