Iron availability can influence microbial communities in the gut

The findings of a recent study suggest that the availability of iron can reshape the composition of the gut microbiota in irreversible ways.

The microbiota may promote sensory neuron regeneration

The findings of a recent study suggest that the microbiota can promote neuronal repair after tissue damage.

Some gut microbes may reverse diet-mediated protection against type 1 diabetes

The findings of a recent study may inform dietary interventions to help protect people against type 1 diabetes and other autoimmune diseases.

Study characterizes alterations of the gut microbiota in Crohn’s disease

The findings of a recent study advance our understanding of bacterial dysbiosis in Crohn’s disease and may inform new therapeutic strategies.

Specific gut bacteria reduce ovarian cancer progression in mice

The findings of a recent study tie the gut microbiota to immune surveillance of ovarian cancer and may inform new treatment approaches.

A mother’s gut microbes share genes with bacteria in the infant gut

A mother’s microbiota may shape the infant gut microbiota through horizontal gene transfer, in addition to the classical transmission of maternal bacteria to the infant’s gut.

Gut microbes may regulate motivation to exercise

The findings of a recent study suggest that signals derived from the gut can boost the motivation to exercise.

Gut microbes may help keep the blood-cerebrospinal fluid barrier intact

A recent study suggests that the blood-cerebrospinal fluid barrier is another barrier along the gut-brain axis that is likely influenced by the gut microbiota.

Microbiotas are transmitted between people that spend time together

A recent study suggests that people who spend time together share similar gut microbiotas — with some microbes being largely transmitted between friends and relatives.

New approach illuminates gut bacteria in living mice

The imaging approach can provide insights into the relationship between mice and their microbiota. It can also offer a glimpse of the cell wall turnover of gut bacteria in living…
