Abstract:
Worldwide incidence and prevalence of ulcerative colitis (UC) has been rising in recent years, which can occur at any age, with a high frequency seen in young children and people aged 40 to 50. The aryl hydrocarbon receptor (AhR) activation axis is well known for its important role in the regulation of intestinal inflammation, intestinal homeostasis, intestinal immune system and improvement of colitis outcomes. This study investigated the therapeutic efficacy of the thiophene-based styrene derivative (TBSD), a novel AhR agonist against UC in vitro and in vivo. TBSD decreased FITC-dextran hyperpermeability, upregulated the tight junction (TJ)-related protein expression levels and regulated the inflammatory mediators including tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6, IL-22 and cyclooxygenase 2 (COX-2) in the Caco-2/RAW264.7 co-culture system and in DSS-induced UC-like mice. Overall, TBSD may be considered as a promising therapeutic agent to improve UC severity through mitigating inflammation, maintaining intestinal mucosal homeostasis and enhancing the intestinal barrier integrity.

Inflammatory Response
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
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...
