Regulatory T cells in the colon travel to muscles to promote wound healing in mice, raising questions about how antibiotics may impact injury recovery.
A neural pathway between the gut and the brain led to the release of dopamine when the mice ran on a wheel or treadmill, but only in the presence of a robust microbiome.
A bacterium that produces an insulin-like peptide can give mice type 1 diabetes, and infection with the microbe seems to predict the onset of the disease in humans, a study finds.
Researchers are going beyond fecal samples to understand how the patterns of commensal microbes in the gastrointestinal tract influence development and health.
A new study has identified a molecular tradeoff between growth and immunity in moths in response to the administration of subtherapeutic doses of antibiotics, a common practice in animal husbandry.
In mice, a kind of immune memory appears to protect the cells against future harm, a finding that could provide insight into treatments for irritable bowel syndrome and other inflammatory digestive conditions.

Work in rodents shows that the bacteria living in a mother’s gut can produce immunomodulatory metabolites and influence the production of maternal antibodies—both of which can affect her offspring’s development.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.
