Who could benefit from this research

Could help

Adults with heavy alcohol use or early-stage alcoholic liver disease who are interested in gut-targeted therapies would be the most likely candidates for this approach.

Less likely to help

People with advanced liver failure, severe immunosuppression, a history of harmful reactions to probiotics, or liver disease unrelated to alcohol may not benefit from this therapy.

What this research studies

This project develops an engineered Lactobacillus probiotic that carries intestinal alkaline phosphatase (IAP) to the gut to neutralize bacterial endotoxin (LPS) and strengthen the intestinal barrier. The team builds on prior mouse work showing oral IAP or Lactobacillus delivery can lower LPS and reduce liver fat and inflammation. The company will optimize the bacterial delivery system to survive the stomach and supply enzyme directly in the intestine and will test activity, stability, and safety in preclinical models. If those steps succeed, the product could move toward human testing for people with alcohol-related gut and liver problems.

Why it matters

Potential benefit: If successful, this approach could lower gut leakiness and endotoxin-driven inflammation and may help prevent or slow alcohol-related liver injury.

How similar studies have gone: Oral alkaline phosphatase and probiotic delivery have shown benefit in animal models of alcohol injury, but human data are limited and this engineered Lactobacillus approach is early-stage and novel for people.
