Understanding how natural brain chemicals with pain-relieving properties interact with administered opioids may guide personalized approaches for pain management.

Danny Winder and colleagues demonstrate an interaction between two signaling pathways — and its impact on the activity of neurons that respond to stress.

Vanderbilt researchers propose that cellular signaling pathways are amplified by a “conveyor belt” mechanism that exchanges active and inactive enzymes.

Targeting the immune system may provide a new avenue for therapeutic intervention in psychiatric diseases characterized by motivational and cognitive deficits.

Bile acids — gut compounds that aid in the digestion of dietary fats — reduce the desire for cocaine, according to a new study by researchers at Vanderbilt and the University of Alabama at Birmingham.

Using techniques to control and monitor the activities of individual neurons, Vanderbilt investigators are probing the brain’s reward circuitry.

Although drug addiction is classically studied in a neuron-centric way, Vanderbilt researchers have discovered that the immune system also plays a critical role.
