An unusual population of immune cells appears to exist in zebrafish as well as mammals.

Two different types of bacteria—one genetically engineered and one from cheese—defend animal intestines from Vibrio cholerae infection.  

Researchers examine the effects on the fruit fly intestine of the protein responsible for Fragile X syndrome in humans. 

Single-cell analyses from mouse samples detail the changes in cell distribution during infections.

Sensory cells of the mouse intestine let the brain know if certain compounds are present by speaking directly to gut neurons via serotonin.
