Popis: Substantial evidence indicate that Antarctic krill oil (KO) is an effective method for alleviating acute ulcerative colitis (UC). Nevertheless, UC is a chronic disease, and the chronic colitis model is more conducive to simulating its pathological characteristics. The objective of this study was to establish a chronic UC model in C57BL/6 mice and identify the regulatory consequences and feasible mechanisms of KO on chronic UC and its associated depressive-like behaviors. The results showed that KO alleviated the pathological features of UC and depression-like behavior. Further mechanisms suggested that KO significantly suppressed gut-brain inflammation, increased the concentration of 5-hydroxytryptamine (5-HT) and the expression of postsynaptic density protein 95 (PSD95) and brain-derived neurotrophic factor (BDNF), protected the integrity of the gut barrier and blood–brain barrier. Moreover, KO maintained the equilibrium of the intestinal flora. The findings suggested that KO may be a promising approach for alleviating UC and its concomitant psychiatric disorders.
