Gut microbes influence cognitive performance in baby mice

The findings of a recent study show that specific gut microbes and their metabolites affect cognition and memory when transplanted into germ-free mice.

Lung bacteria may be associated with brain conditions after severe pneumonia

By suggesting that the bacteria detected in the brain after severe pneumonia originate from the lungs, the findings shed light onto the mechanisms of pneumonia-induced neurological conditions.

Alterations in the gut microbiota may drive binge eating, mice study suggests

The findings of a recent study suggest that the interplay between the microbiota, the gut and the brain drives binge-eating disorders.

Socio-economic adversities are associated with gut microbiota alterations

Microbial differences may help to identify targets that could be modulated to mitigate health inequities.

Autism: study identifies molecular and microbial profiles that may be behind the gut-brain axis

The authors propose a framework to leverage multi-omic datasets obtained from well-defined cohorts and to examine the impact of the GBA on ASD.

Gut microbiota may be linked to Alzheimer’s disease risk, clinical study finds

Understanding how gut microbes are linked to preclinical Alzheimer’s disease could help to identify markers of disease risk.

Estrogen and gut microbiome-brain axis interactions in fear extinction

A recent review highlights that changes in fear-related mental health conditions are observed when the gut microbiota is altered or removed.

A cross-sectional study on the link between gut microbiota and inflammation in bipolar depression

Depressed BD patients present significant alterations in the taxonomic compositions of their gut microbiota, and this may be related to inflammatory pathways and depression severity.

Cocaine users have disrupted gut and oral microbiotas

Cocaine users have an altered gut and oral microbiota composition and function, which can be rescued by rTMS-induced cocaine abstinence.

Epsilon toxin-producing Clostridium perfringens colonize the gut of multiple sclerosis patients

ETX-producing C. perfringens strains are biologically plausible pathogens in MS that trigger inflammatory demyelination.
