Natural polyamines, such as spermidine and spermine, exert strong anti-inflammatory effects, but their therapeutic benefits are limited by rapid absorption in the small intestine, resulting in low colonic availability. In this study, engineered Citrobacter freundii overexpressing ppk1 (CPP) coul...
This study applies untargeted liquid chromatography–mass spectrometry (LC–MS)–based serum metabolomics to characterize metabolic alterations in a dextran sulfate sodium–induced colitis mouse model and to evaluate the therapeutic effects of the microbiota-regulating nanomedicine MRA_RP. Serum samp...
BACKGROUND: Ulcerative colitis (UC) is a chronic recurrent inflammatory disease of the gastrointestinal tract. Recent studies demonstrate that the phenolic tannin paeonol (Pae) attenuates UC in mouse models by downregulating inflammatory factors; however, molecular mechanisms lin...
Background: Gut microbiota dysbiosis is a critical contributor to the pathogenesis and progression of inflammatory bowel disease (IBD). Darutigenol (DL), a natural compound has demonstrated significant anti-inflammatory activity, but its low oral bioavailability limits its application. However, t...
This study investigated the effects of Bacillus licheniformis supplementation on the gut metabolic profile of patients with mild-to-moderate active ulcerative colitis (UC). Patients received either mesalazine alone or mesalazine combined with Bacillus licheniformis. Fecal samples were collected a...
