Not exact matches

As noted by Dr. Vicki Ellingrod — the Chair of this session, «Current state - of - the - art research in both animal models as well as humans point to the link between the gut microbiota and mood and anxiety models, as well as the potential for psychiatric medications to directly affect the gut microbiome.»

In addition, cohousing coprophagic mice harboring transplanted microbiota from discordant pairs provides an opportunity to determine which bacterial taxa invade the gut communities of cage mates, how invasion correlates with host phenotypes, and how invasion and microbial niche are affected by human diets.

A deep global analysis of the gut microbiota composition was done by phylogenetic microarray analysis using a Human Intestinal Tract Chip (HITChip), an analytical device designed specifically for studying gut bacteria.

The findings illuminate the specialized roles played by key members of the vast microbial community living in the human gut, and could inform the development of tailored microbiota transplants to improve intestinal health after antibiotic use or illness.

Spurred by this finding, Littman's team examined the gut microbiota in patients with rheumatoid arthritis, a debilitating autoimmune disease, and found a much higher proportion of patients than healthy individuals who harbored the human intestinal bacterium Prevotella copri.

The great news is that by adding fermented veggies into your foods, you are changing your gut health for better: «the composition of the gut microbiota has been shown to differ in lean and obese humans and animals and to change rapidly in response to dietary factors.

Hence, a lot of necessary neurotransmitters in the body are generated by the gut microbiota, exerting influence on the human body including the brain, among which many neurotransmitters in the human gut microbiota are also critical molecules.»

Nutrition - derived bioactive metabolites produced by gut microbiota and their potential impact on human health

The delicate balance between the human microbiome and the development of psychopathologies is particularly interesting given the ease with which the microbiome can be altered by external factors, such as diet, 23 exposure to antimicrobials24, 25 or disrupted sleep patterns.26 For example, a link between antibiotic exposure and altered brain function is well evidenced by the psychiatric side - effects of antibiotics, which range from anxiety and panic to major depression, psychosis and delirium.1 A recent large population study reported that treatment with a single antibiotic course was associated with an increased risk for depression and anxiety, rising with multiple exposures.27 Bercik et al. 28 showed that oral administration of non-absorbable antimicrobials transiently altered the composition of the gut microbiota in adult mice and increased exploratory behaviour and hippocampal expression of brain - derived neurotrophic factor (BDNF), while intraperitoneal administration had no effect on behaviour.

Artificial sweeteners have been shown to cause glucose intolerance in mice by altering gut microbiota and are associated with dysbiosis and glucose intolerance in humans.
