Exendin-4 Attenuates Hepatic Steatosis by Promoting the Autophagy-Lysosomal Pathway.

Summary: Fatty liver disease can cause serious liver damage. Scientists are testing a drug called Exendin-4 to treat it. They found that Exendin-4 works like a cellular cleanup crew. It boosts a natural process called "autophagy," which helps liver cells break down and clear out harmful fat. When scientists blocked this cleanup process in the lab, the drug stopped working. This shows Exendin-4 relies heavily on the cell's own recycling system to successfully clear out liver fat!
