Highlights•Environmental pollution could affect diversity of resident microbiota. •Environmental pollution could affect abundance of resident microbiota. •Studies suggest air pollution increases the abundance of streptococcus. •Studies suggest air pollution increases the abundance of veillionellales. •Scarcity of studies precludes observing consistent trends for other microbiota. AbstractA rich body of literature indicates that environmental factors interact with … Continue reading Air pollution and endocrine disruptors induce human microbiome imbalances: A systematic review of recent evidence and possible biological mechanisms

The endocannabinoid (EC) system has pleiotropic functions in the body. It plays a key role in energy homeostasis and the development of metabolic disorders being a mediator in the relationship between the gut microbiota and host metabolism. In the current study we explore the functional interactions between the endocannabinoid system and the gut microbiome in … Continue reading The anti-inflammatory effect of bacterial short chain fatty acids is partially mediated by endocannabinoids
Patterns of diurnal activity differ substantially between individuals, with early risers and late sleepers being examples of opposite chronotypes. Growing evidence suggests that the late chronotype significantly impacts the risk of developing mood disorders, obesity, diabetes, and other chronic diseases. Despite the vast potential of utilizing chronotype information for precision medicine, those factors that shape … Continue reading Metagenomic analysis reveals the signature of gut microbiota associated with human chronotypes
Autophagy, an essential intracellular recycling process, is linked to the pathogenesis of various diseases including Crohn’s disease (CD). Factors that lead to the development of impaired autophagy during intestinal inflammation remain largely unexplored. Here, we report the impact of the interaction between serotonin [5-hydroxytryptamine;(5-HT)] and autophagy in colitis in mouse and human studies. In mice, … Continue reading Disruption of autophagy by increased #5-HT alters gut microbiota and enhances susceptibility to experimental colitis and #Crohn’s disease
Irritable bowel syndrome (IBS) results from disordered brain–gut interactions. Identifying susceptibility genes could highlight the underlying pathophysiological mechanisms. We designed a digestive health questionnaire for UK Biobank and combined identified cases with IBS with independent cohorts. We conducted a genome-wide association study with 53,400 cases and 433,201 controls and replicated significant associations in a 23andMe … Continue reading Genome-wide analysis of 53,400 people with #irritable bowel syndrome highlights shared genetic pathways with #mood and #anxiety disorders
