WebJun 25, 2024 · When faced with environmental stress, cells respond by shutting down cellular processes such as translation and nucleocytoplasmic transport. At the same time, cells preserve cytoplasmic messenger RNAs in structures known as stress granules, and many cellular proteins are modified by the covalent addition of ubiquitin, which has long … WebLC3-decorated transient compartments that engulf cytosolic cargo for subsequent delivery to the lysosomes for degrada-tion. We recently discovered that Paneth cells respond to bac-terial invasion by rerouting lysozyme through an autophagy-based alternative secretion system termed secretory autophagy.
