Abstract:
The increasing prevalence of inflammatory bowel disease (IBD) imposes a substantial economic burden, and its pathogenesis is associated with dietary fat intake. Short-chain fatty acids (SCFAs) regulate intestinal inflammation and immunity by inhibiting histone deacetylases (HDACs) or binding to G protein-coupled receptors (GPCRs). Specialized pro-resolving mediators (SPMs) derived from polyunsaturated fatty acids (PUFAs) contribute to inflammation resolution. Fatty acid oxidation (FAO) is a primary energy source for intestinal epithelial cells. Previous studies indicate that patients with IBD exhibit decreased levels of SCFAs and reduced intermediates of the tricarboxylic acid (TCA) cycle, suggesting impaired FAO. These alterations may exacerbate intestinal inflammation through energy deficiency in intestinal epithelial cells, barrier disruption, and dysregulated immune cell polarization. This review aims to broaden therapeutic options by identifying underlying targets and proposing potential strategies.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
