Cumulative evidence shows a linkage between gut microbiota pattern and depression through the brain-gut microbiome axis. The aim of this systematic review was to identify the alterations of the gut microbiota patterns in people with depression compared to healthy controls. A comprehensive literature search of human studies, published between January 2000 and June 2019, was… Continue reading Altered Composition of Gut #Microbiota in #Depression: A Systematic Review

#Intestinal barrier dysfunction plays an integral role in #arthritis pathology and can be targeted to ameliorate disease
HighlightsSerum gut-permeability markers LPB, LPS, and I-FABP are increased in RAMice with arthritis have increased gut permeability and intestinal inflammationBoth bacteria and leukocytes are needed to disrupt gut-barrier integrityPrevention of gut-barrier dysfunction in arthritis ameliorates joint inflammation Context and significanceRheumatoid arthritis is an autoimmune disorder characterized by chronic joint inflammation. Accumulating evidence suggests that changes… Continue reading #Intestinal barrier dysfunction plays an integral role in #arthritis pathology and can be targeted to ameliorate disease
High- #fat diet–induced #colonocyte dysfunction escalates microbiota-derived trimethylamine N-oxide
A Western-style, high-fat diet promotes cardiovascular disease, in part because it is rich in choline, which is converted to trimethylamine (TMA) by the gut microbiota. However, whether diet-induced changes in intestinal physiology can alter the metabolic capacity of the microbiota remains unknown. Using a mouse model of diet-induced obesity, we show that chronic exposure to… Continue reading High- #fat diet–induced #colonocyte dysfunction escalates microbiota-derived trimethylamine N-oxide
#Gut-microbiota-targeted #diets modulate human immune status
Diet intervention with systems profiling reveals links in diet-microbiome-immune axis•High-fiber diet changes microbiome function and elicits personalized immune responses•Fermented-food diet increases microbiome diversity and decreases markers of inflammation SummaryDiet modulates the gut microbiome, which in turn can impact the immune system. Here, we determined how two microbiota-targeted dietary interventions, plant-based fiber and fermented foods, influence… Continue reading #Gut-microbiota-targeted #diets modulate human immune status
Gut #microbiome heritability is nearly universal but environmentally contingent
Baboons inform on human gut microbiotaCommensal bacteria are found throughout an organism, but it is not known whether associations between gut bacteria and their host are heritable. Grieneisen et al. examined changes in the microbiomes of 585 wild baboons from fecal samples collected over 14 years (see the Perspective by Cortes-Ortiz and Amato). Almost all… Continue reading Gut #microbiome heritability is nearly universal but environmentally contingent
#Gut microbes impact #stroke severity via the trimethylamine N-oxide pathway
Clinical studies have demonstrated associations between circulating levels of the gut-microbiota-derived metabolite trimethylamine-N-oxide (TMAO) and stroke incident risk. However, a causal role of gut microbes in stroke has not yet been demonstrated. Herein we show that gut microbes, through dietary choline and TMAO generation, directly impact cerebral infarct size and adverse outcomes following stroke. Fecal… Continue reading #Gut microbes impact #stroke severity via the trimethylamine N-oxide pathway
Artificial #Sweeteners Negatively Regulate Pathogenic Characteristics of Two Model #Gut Bacteria, E. coli and E. faecalis
Artificial sweeteners (AS) are synthetic sugar substitutes that are commonly consumed in the diet. Recent studies have indicated considerable health risks which links the consumption of AS with metabolic derangements and gut microbiota perturbations. Despite these studies, there is still limited data on how AS impacts the commensal microbiota to cause pathogenicity. The present study… Continue reading Artificial #Sweeteners Negatively Regulate Pathogenic Characteristics of Two Model #Gut Bacteria, E. coli and E. faecalis
Timing of #chocolate intake affects hunger, substrate oxidation, and #microbiota: A randomized controlled trial
Eating chocolate in the morning or in the evening/at night, may differentially affect energy balance and impact body weight due to changes in energy intake, substrate oxidation, microbiota (composition/function), and circadian-related variables. In a randomized controlled trial, postmenopausal females (n = 19) had 100 g of chocolate in the morning (MC), in the evening/at night… Continue reading Timing of #chocolate intake affects hunger, substrate oxidation, and #microbiota: A randomized controlled trial
Colonization of the #Caenorhabditis elegans gut with human enteric bacterial pathogens leads to proteostasis disruption that is rescued by butyrate
Protein conformational diseases are characterized by misfolding and toxic aggregation of metastable proteins, often culminating in neurodegeneration. Enteric bacteria influence the pathogenesis of neurodegenerative diseases; however, the complexity of the human microbiome hinders our understanding of how individual microbes influence these diseases. Disruption of host protein homeostasis, or proteostasis, affects the onset and progression of… Continue reading Colonization of the #Caenorhabditis elegans gut with human enteric bacterial pathogens leads to proteostasis disruption that is rescued by butyrate
