Gut bacteria and how they influence alcohol seeking and decisions

Official title: The role of the gut microbiota in alcohol seeking and decision-making

Funded at University of Maryland Baltimore · NIH-11404984 · Data updated 2026-11-12

This project looks at whether the bacteria living in the gut affect how people or animals seek alcohol and make decisions about drinking.

Who could benefit from this research

Could help

Ideal candidates are individuals with alcohol use concerns in future translational steps or related patient populations who might contribute samples or participate in follow-on studies.

Less likely to help

People without alcohol use concerns or those unlikely to participate in microbiome-related research may see no direct benefit.

What this research studies

Researchers will study mice to see if altering gut microbes changes how much alcohol they seek and how they decide to drink. They will use prebiotics to shift the gut bacteria and fecal transplants from prebiotic-treated donors to test cause-and-effect. The findings could reveal gut-related targets for reducing problematic drinking and improving related behaviors. The work focuses on how the gut–brain axis may shape reward processing in the context of alcohol use.

Why it matters

Potential benefit: If successful, this work could point to gut microbiome-based strategies to reduce alcohol craving and harmful drinking behaviors.

How similar studies have gone: Preliminary studies in animals suggest the gut microbiome can influence alcohol-related behaviors, supporting a promising but still emerging approach.
