Short chain fatty acids readily crosses the gut-blood and blood–brain barrier and acts centrally to influence neuronal signaling. We hypothesized that butyrate, a short-chain fatty acid produced by bacterial fermentation, in the central nervous system may play a role in the regulation of intestinal functions. Colonic permeability and visceral sensation was evaluated in rats. Septic […]
Parkinson’s disease (PD) is a complicated neurodegenerative disease attributed to multifactorial changes. However, its pathological mechanism remains undetermined. Accumulating evidence has revealed the emerging functions of gut microbiota and microbial metabolites, which can affect both the enteric nervous system and the central nervous system via the microbiota-gut-brain axis. Accordingly, intestinal dysbiosis might be closely associated

Finally, the pros and cons of the current treatments for PD, including those targeting microbiota, are assessed. Advancements in research techniques, further studies on levels of specific strains and longitudinal prospective clinical trials are urgently needed for the identification of early diagnostic markers and the development of novel therapeutic approaches for PD.

This review provides an overview of the current knowledge of these effects, with specific focus on energy metabolism, intestinal barrier, immune system, and disease activity in IBD. To conclude, more research is needed on the cross-feeding mechanisms in the gut microbiome, as well as on the therapeutic potential of SCFAs on different disease models. Also

Overall, our data suggested that β-glucan could be completely hydrolyzed by human fecal microbiota but not thoroughly degraded by mice fecal microbiota. The notion shed some light on the effect of gut microbial source on β-glucan degradation, providing new information for the relationship between β-glucan metabolism and gut microbiota.

After in vitro digestion and anaerobic fermentation, both O. sinensis and C. militaris could modulate the gut microbiota composition through reducing the ratio of Firmicutes to Bacteroidetes. Moreover, this research demonstrated that O. sinensis had more positive effects on the intestinalhealth compared with C. militaris via decreasing the pH of gut environment, stimulating the production
. Additionally, in animals, 3-HB is not only an intermediate metabolite, but also an important regulatory molecule that can influence gene expression, lipid metabolism, neuronal function, and overall metabolic rate. Some of these effects are the direct effects of 3-HB itself, while others are indirect effects, regulated by the metabolites into which 3-HB is converted.
In conclusion, niacin attenuated the weight loss and diarrhea, and improved the expression of antimicrobial peptides, and enhanced intestinal epithelial barrier function, and improved the microbiota in the colonic contents of weaned piglets, suggesting that niacin may be an effective way for weaned piglets to maintain the gut and overall health.

These findings suggest that varieties in dietary patterns result in the production of diverse microbial fermentation metabolites, which contribute to gut microbiome homeostasis through multiple manipulations including immune modulation, inflammation restriction as well as epithelial barrier maintenance, thus finally determine the fate of UC progression and give implications for functional food development for prevention and
The data suggests that changing the gut microbiota composition by dietary restriction has the potential to positively influence the progression of several diseases such as obesity, diabetes, neurological diseases or inflammatory bowel disease. Finally, the relevance of the findings for clinical practice is evaluated and approaches for future research are proposed. CLICK TO REVIEW
