How do disease-specific intracellular environments alter TFEB post-translational modification profiles?

The abstract states that pathological states create specific stressors that elicit distinct TFEB modifications, but the mechanistic link between disease context and modification patterns remains unclear. This knowledge gap limits precision therapeutic approaches targeting TFEB.
