Bioengineered probiotic to curb binge drinking

Official title: Development of a Bioengineered Probiotic Strain to Reduce Binge Drinking

Funded at University of Connecticut Sch of Med/dnt · NIH-11448028 · Data updated 2026-11-12

A new probiotic therapy is being developed to produce a gut metabolite that helps reduce binge drinking in people by delivering it continuously in the gut.

Who could benefit from this research

Could help

Ideal candidates are individuals with alcohol use disorders or problematic binge drinking who are open to microbiome-based therapies in the future.

Less likely to help

Individuals without AUD or those unwilling to consider microbiome interventions may not benefit.

What this research studies

This project will engineer a probiotic strain to steadily produce valeric acid in the gut, aiming to lower binge drinking behavior. Researchers will create and test several VA-producing probiotic candidates in the lab and measure how much VA they generate. They will also add a cold-inducible kill switch to prevent unintended release and improve safety. The study will use a mouse model to explore whether these engineered probiotics can influence drinking behavior before considering human studies.

Why it matters

Potential benefit: If successful, this approach could provide a new, microbiome-based option to help reduce binge alcohol consumption.

How similar studies have gone: Preclinical work has shown that gut metabolites can influence alcohol intake, but this specific probiotic approach is novel.
