Article Title: Anti-Inflammatory Effect of IL-37-Producing T-Cell Population in DSS-Induced Chronic Inflammatory Bowel Disease in Mice
Figure Lengend Snippet: IL-37 + T-cells play a protective role in DSS-induced chronic colitis in mice. ( A ) Relative weight curves of WT mice, DSS-induced WT mice, DSS-induced WT mice treated with PBS, and DSS-induced WT mice injected with IL-37 + T-cells in chronic colitis. The statistical significance between the relative weights of DSS-induced mice injected with IL-37 + T-cells versus DSS-induced mice treated with PBS at the end of the experiment is shown. ( B ) The disease activity index (DAI) was determined at day 63 of the study period, based on body weight loss (0, none; 1, 1–5%; 2, 5–10%; 3, 10–20%; 4, > 20%), stool consistency (0, normal; 2, loose stool; 4, diarrhea), and stool blood (0, negative; 2, fecal occult blood test positive; 4, gross bleeding). ( C ) Representative pictures of the colon from indicated treatment cohorts. ( D ) Macroscopic damage score of the colon in the four groups. ( E ) Representative haematoxylin and eosin (H E) staining of colon sections of mice. ( F ) Histological inflammation score. This score comprises the sum of architecture of the bowel, infiltration of neutrophils and mononuclear cells, gobleT-cell depletion, and epithelial cell erosion. Three sections per animal were evaluated. ( G ) Expressions of IFN-γ, IL-1β, TNF-α, and IL-10 mRNAs within colonic tissues in the four groups. Total RNA with the RNAiso Plusi Kit. cDNAs were synthesized by using the RevertAid First Strand cDNA Synthesis Kit according to the manufacturer’s instructions. qPCR amplification reactions were prepared with the SYBR Green PCR Kit and performed using the CFX96 Real-Time System. Data are means ± SEM ( n = 6). * p
