Glucose metabolism influences the qualities of activated, mature B cells — white blood cells that are required for antibody-mediated immune responses, Vanderbilt researchers discovered.

Vanderbilt researchers have discovered that beneficial bacteria in the small intestines produce a compound that protects against obesity.

Pasteurization of breast milk affects the concentration of osteopontin, a bioactive protein with roles in intestinal, immunological and brain development — suggesting that osteopontin supplementation should be considered when donor milk is provided to preterm infants.

The commensal bacterium Turicibacter sanguinis could be used to protect against severe intestinal infections, Vanderbilt researchers discovered.

Vanderbilt research discovers that iron storage “spheres” inside the bacterium C. diff — the leading cause of hospital-acquired infections — are important for infection in an animal model and could offer new targets for antibacterial drugs.

Vanderbilt research shows that commensal gut microbes impact the host-pathogen competition for iron and has implications for therapeutic strategies aimed at preventing pathogens from acquiring essential nutrients.
