Curcumin,a natural product,has exhibited promising effects in both animal models and clinical trials,interacting with a multitude of factors linked to Inflammatory Bowel Disease(IBD).These factors encompass cytokines,oxidative stress-associated enzymes,and modulation of the intestinal ***,curcumin has demonstrated therapeutic potential in animal models of colitis,wherein it exerts a negative regulatory influence on pivotal signaling pathways such as PI3/Akt,JAK/STAT,andβ-***,it inhibits the expression of proinflammatory enzymes and co-stimulatory molecules(including RANKL,ICAM-1,CD205,CD256,TLR4,among others),while curbing immune cell chemotaxis,thereby attenuating the characteristic neutrophil infiltration observed in *** facet of curcumin’s action involves its modulation of the intestinal ***,the microbiota itself contributes to beneficial biotrans formations of curcumin,thereby enhancing its effectiveness in IBD *** a clinical front,curcumin has demonstrated the ability to induce clinical and/or endoscopic remission without any reported toxic ***,curcumin warrants consideration as an adjunctive therapy in IBD *** clinical investigations should concentrate on meticulously evaluating curcumin’s impact on these precise therapeutic targets.
