Obesity and its associated comorbidities have emerged as a major public health crisis. Accumulating evidence indicates that a high fat diet (HFD) may promote intestinal injury. However, the roles of intestinal goblet cells and specific gut microbiota composition in colitis under obesity conditions remain unclear. In this study, we employed a HFD-induced obesity model combined with dextran sulfate sodium (DSS) to induce colitis in mice. Our results reveal that obesity exacerbates DSS-induced colitis in the colon, as evidenced by increased intestinal barrier injury. These changes are associated ...
