Regulatory T cells in the colon travel to muscles to promote wound healing in mice, raising questions about how antibiotics may impact injury recovery.
The immune system tolerates the colonization of commensal bacteria on the skin with the aid of regulatory T cells during the first few weeks of life, a mouse study shows.
Researchers are going beyond fecal samples to understand how the patterns of commensal microbes in the gastrointestinal tract influence development and health.
