Early-life exposure to antibiotics could impact brain development in areas associated with emotional and cognitive function, a new study reports. Researchers found penicillin exposure in infant mice altered the microbiome and gene expression in key areas of the developing brain.
Infant boys with a gut bacterial composition high in Bacteroidetes were found to have more advanced cognitive and language skills one year later compared to boys with lower levels of the bacteria.
Researchers identified the gut bacteria E. faecalis as a mediator of social behavior and corticosterone levels in mice.
Gut microbes that metabolize tryptophan secrete indoles that stimulate the development of new neurons in the adult brain.
Taking a daily prebiotic supplement improves general wellbeing, reduces symptoms of anxiety, and promotes better gut health, a new study reports.
Immune cells in the uterus and placenta of stressed pregnant mice were not activated, but researchers found increased levels of inflammation in the developing fetal brain. Additionally, prenatal stress led to reductions in gut microbial strains and functions, especially in those linked to inflammation.
A meta-analysis study reveals alterations in the gut microbiome may trigger gastrointestinal problems associated with Parkinson's disease. Additionally, the gastrointestinal problems may occur years before other Parkinson's symptoms develop.
