Berberine-taxifolin co-administration attenuates inflammatory response and intestinal barrier injury via nf-κB/NLRP3 suppression in colitis

Abstract

Inflammatory bowel disease (IBD) is pathologically characterized by dysregulated inflammation and compromised intestinal barrier integrity. While multi-component herbal formulations hold promise for IBD management, the combined potential of specific phytochemical combinations remains underexplored. This study investigates the cooperative therapeutic effects of Berberine and Taxifolin, two anti-inflammatory phytochemicals, in a murine colitis model. Multi-omics network pharmacology initially identified their shared anti-inflammatory and anti-apoptotic targets in IBD pathogenesis. Experimental validation demonstrated that combined treatment with berberine and taxifolin produced stronger protective effects against Dextran Sulfate Sodium (DSS)-induced colitis than either compound alone. Specifically, the combination significantly alleviated body weight loss and colon shortening, reduced macrophage infiltration and the expression of pro-inflammatory cytokines (IL-1β and TNF-α), and preserved intestinal barrier integrity by restoring tight junction proteins (occludin and ZO-1). In addition, the combined treatment attenuated caspase-3-mediated epithelial apoptosis. Molecular docking analysis suggested that berberine and taxifolin may interact with multiple inflammation-related targets, including NF-κB, NLRP3, PPARγ, and STAT3, providing a potential mechanistic basis for the observed effects. These findings establish Berberine-Taxifolin co-administration as a novel multi-target therapeutic strategy that concurrently addresses inflammatory dysregulation, barrier repair, and apoptosis control in IBD, and may provide a phytochemical blueprint for complex inflammatory disorders.
