Preventing lysosomal fat indigestion
Abstract
Autophagy contributes to lipid catabolism through direct mobilization and breakdown of cellular lipid stores. Two recent studies reveal the regulatory mechanisms activated by cells during starvation to ensure that the cellular compartments involved in autophagic lipid catabolism are ready to receive, process and use these lipids. The regulators represent attractive therapeutic targets to help fight lipid-excess-associated diseases.
