Why liver cells can't clean themselves in fatty liver disease
Inhibition of mTOR improves the impairment of acidification in autophagic vesicles caused by hepatic steatosis.

Surprising Findings
Despite increased autophagosome formation, waste still accumulates in fatty liver cells.
Most people assume more autophagosomes mean more cleanup, but here, the process is blocked downstream—acidification fails, so digestion doesn’t happen.
Practical Takeaways
Lifestyle changes that reduce mTOR activation (like intermittent fasting or protein moderation) might support liver cell cleanup function.

In fat mice with fatty liver, the liver cells have fewer 'acidic cleanup pockets' than healthy mice, which might mean their cells aren't cleaning themselves properly.
Treating liver cells from diabetic mice with a drug called rapamycin seems to boost their waste-cleaning process, which might help clear fat buildup in the liver.
In mice with fatty liver, certain proteins and their genetic instructions are lower in the liver's waste-processing units, which might mean those units aren't working as well as they should.
