Nanovesicle treatment reduces alcohol-related liver damage in mice

Researchers tested nanovesicles as a possible treatment for alcohol-related liver disease in mice fed alcohol.

The tiny, biologically active particles came from healthy pig tissue and are found within the framework that supports tissues.

A single injection reduced liver injury, fat buildup and oxidative damage in the mice.

It also partly reversed alcohol-related changes in liver gene activity without broadly suppressing the immune response.

The findings matter because treatments that directly target the underlying liver injury are limited, and alcohol-related disease accounts for nearly half of cirrhosis cases in the United States.

The work is an early proof of concept in mice, so it does not change care for people now.

Researchers say it opens a new path for developing treatments, but the study does not say when or whether the approach will be tested in people.
