What this research studies

This research compares the fungal communities in the intestines of people with alcohol use disorder and in mice given chronic alcohol. It follows how Candida and Malassezia species can move from the gut to the liver and trigger immune cells that cause inflammation. The team studies intestinal T cell responses, production of the inflammatory molecule IL-17, and how fungal products activate liver Kupffer cells via the Dectin-2 receptor. The goal is to pinpoint fungal-driven pathways that could be targeted to reduce alcohol-related liver injury.

Who could benefit from this research

Good fit: Ideal participants are adults with alcohol use disorder or alcohol-associated liver disease who can provide stool, blood, or clinical information for research.

Not a fit: People whose liver disease is caused by non-alcohol-related conditions (for example viral hepatitis or genetic/metabolic liver diseases) may not directly benefit from these findings.

Why it matters

Potential benefit: If successful, the work could point to new ways to prevent or reduce alcohol-related liver inflammation by targeting gut fungi or the immune pathways they trigger.

How similar studies have performed: Previous patient-sample analyses and mouse experiments have reported more Candida and Malassezia with alcohol use and linked fungal antigens to liver inflammation, but targeting gut fungi in people is still an emerging approach.
