Impact of intrarectal chromofungin treatment on dendritic cells-related markers in different immune compartments in colonic inflammatory conditions

Figure 2 Chromofungin (chromogranin-A 47-66) treatment decreases colonic cluster of differentiation markers and interleukin-12 level in dextran sulphate sodium-induced experimental colitis. Colitis was induced with 5% dextran sulphate sodium in drinking water to C57BL/6 male mice, and the control group of mice received regular drinking water. Chromofungin (2.5 mg/kg per day, i.r.) was given as a preventive treatment or phosphate buffer saline (1%) starting from one day before the induction of colitis till the fifth day when the mice were sacrificed. A-F: CD86 (A), CD80 (B), CD40 (C), CD11c (D), interleukin (IL)-12p40 mRNA expression (E), IL-12p40 protein level (F). mRNA expression was quantified by quantitative real-time reverse-transcription polymerase chain reaction and protein level by ELISA. One-way ANOVA followed by multiple comparison tests was used to analyze the data, and adjusted P equal to or smaller than 0.05 is believed to be significant. Each value represents the mean ± SE, n = 6 mice/group. PBS: Phosphate buffer saline; CHR: Chromofungin; DSS: Dextran sulphate sodium.
