Peptides derived from the antimicrobial peptides secreted by frogs could function as microbicides to limit HIV transmission, while sparing protective vaginal bacteria.

Histamine — commonly associated with allergies — also has a signaling role in the brain’s reward center and may offer a novel target for treating addiction.

Vanderbilt epidemiologists identified new markers for colorectal cancer risk and characterized a previously unidentified tumor suppressor that regulates overall tumor volume in vivo.

A new method that keeps microbes and gut cells together will be useful for studies of complex host-microbe interactions and for analysis of clinical specimens.

Older depressed adults show accelerated brain aging, according to a new study from Vanderbilt researchers, who suggest that the effects of depression may speed the decline in cognitive functions in older individuals.

It might be possible to use vesicles carrying the receptor for SARS-CoV-2, the virus that causes COVID-19, to bind the virus and prevent infection.

The brain’s response to low oxygen — growth and remodeling of blood vessels — involves certain cell types and molecular pathways, Vanderbilt researchers have discovered.
