Core Tip

Core tip: Inflammatory bowel disease (IBD) is a systemic disease, as it is often associated with extra-intestinal manifestations, complications, and other autoimmune disorders. However, it is unknown whether dermal lymphatic function changes systemically in response to IBD. In this study, we employed near-infrared fluorescence imaging to characterize dermal lymphatic function and architecture in mice with dextran sulfate sodium (DSS)-induced acute colitis. Our results demonstrated impaired lymphatic function in mesenteric lymphatics accompanied by dilated lymphatic vessels and reduced lymphatic contractility in the skin of mice with DSS-induced acute colitis, indicating that DSS-induced acute colitis results in systemic lymphatic dysfunction.
