Probiotics are defined as 'live microorganisms which when administered in adequate amounts confer a health benefit on the host'. So, to consider a microorganism as a probiotic, a demonstrable beneficial effect on the health host should be shown as well as an adequate defined safety status and the capacity to survive transit through the gastrointestinal tract and to storage conditions. In this review, we present an overview of the murine colitis models currently employed to test the beneficial effect of the probiotic strains as well as an overview of the probiotics already tested. Our aim is to highlight both the importance of the adequate selection of the animal model to test the potential probiotic strains and of the value of the knowledge generated by these in vivo tests.

Innate and adaptive immunity are intricately linked to the pathogenesis of ulcerative colitis (UC), with dysregulation of the Treg/Th17 balance and M2/M1 macrophage polarization identified as critical factors. Artesunate (ARS) has previously been shown to alleviate UC by inhibiting endoplasmic reticulum stress (ERS). To further investigate the regulatory effects of ARS on immune dysregulation associated with colitis and the role of ERS in this process, an experimental colitis model was established using dextran sulfate sodium (DSS).

Colitis is a complicated disease caused by multiple factors, seriously threatening the host health and the development of animal husbandry. Probiotics have been demonstrate to participate in the active regulation of multiple gastrointestinal disease, gut microbiota and metabolism, but research on the efficacy of isolated from dogs in alleviating colitis remains scarce. Here, we aimed to investigate the ameliorative effects of isolated from dogs on colitis induced by LPS and its underlying molecular mechanisms.

Ulcerative colitis (UC) is a chronic inflammatory disease with an increasing prevalence worldwide. Naringenin (NAR) has been proven effective in preventing UC, but its mechanism has not been fully elucidated. In this study, network pharmacology and bioinformatics methods are used to screen the genes associated with NAR and UC.

Thymol (THY) is a phenolic monoterpene compound that has garnered attention due to its various biological properties, including antioxidant, anti-inflammatory, and immune-regulatory effects. The purpose of this study was to determine the therapeutic and protective effects of THY in colitic mice, with a particular focus on the mechanisms involving gut microbiota. The results showed that early intervention with THY (40 and 80 mg/kg) not only alleviated the clinical symptoms and colonic damage in mice with dextran sodium sulfate (DSS)-induced colitis but also suppressed the colonic production of inflammatory cytokines (IL-1β, IL-6, and IL-18) and enhanced the expression of mucins (MUC1 and MUC2) and trefoil factor family 3 (TFF3), thereby improving the integrity of the intestinal epithelial barrier.

: Exposure to fine particulate matter (PM) causes significant respiratory and gastrointestinal health problems. In our prior research, we identified TW01 as a promising strain for mitigating oxidative damage, enhancing wound healing in intestinal epithelial cells, and protecting bronchial cells from cigarette smoke extract. Building upon these findings, this study examines the protective effects of this strain on lung damage induced by particulate matter (PM) through the gut-lung axis in mouse models.
