What this research studies

This project builds on findings that alcohol changes immune signaling in the brain and may promote heavier drinking. Researchers will use mice that lack key genes in the type 1 interferon (IFN1) pathway and will give drugs that block IFN1 signaling to see how these changes affect drinking and alcohol-related behaviors using an every-other-day two-bottle choice method. They will measure interferon-stimulated genes and other downstream signaling molecules linked to Toll-like receptor pathways to understand how these immune signals influence drinking. The goal is to identify immune-related mechanisms that could be targeted to reduce excessive alcohol intake.

Who could benefit from this research

Good fit: Adults who drink heavily or who have been diagnosed with alcohol use disorder would be the likely candidates for future clinical trials based on this work.

Not a fit: People who only drink socially or whose drinking is driven by non-biological factors may not receive direct benefit from treatments targeting interferon signaling.

Why it matters

Potential benefit: If successful, this work could point to new drug targets that reduce excessive drinking in people with alcohol use disorder.

How similar studies have performed: Previous animal and human studies have linked immune and Toll-like receptor signaling to alcohol use, but directly targeting interferon signaling as a treatment is largely untested in people.
