        | Core Tip | Mitochondrial dysfunction in intestinal mucosa is emerging as a novel mechanism in inflammatory bowel disease pathogenesis. In the present study, we show that growth differentiation factor 15 (GDF15), a marker of mitochondrial stress, is elevated in plasma from both ulcerative colitis and Crohn’s disease patients. Furthermore, levels of GDF15 correlate with markers of inflammation and intestinal permeability. In vitro assays using colonic organoids further showed that GDF15 alters the intestinal barrier, reducing the levels of zonula occludens 1 and claudin 1, and subsequently increases intestinal permeability. Targeting GDF15 may offer a promising strategy to prevent disruption of the intestinal barrier, potentially reducing immune overactivation. |
