Self-Cleaning Processes and Cell Factory Changes During Cell Development

The endoplasmic reticulum (ER) is crucial for protein and lipid synthesis and undergoes extensive remodeling during cellular differentiation.

• The ER is a dynamic organelle that supports various cellular processes through its constantly reshaping membrane network.
• Cellular differentiation requires significant changes in the ER's structure and protein composition to match new cell functions.
• Autophagy, especially ER-phagy, is important for modifying the ER to help cells adapt to developmental changes.
• Current understanding of how the dynamics of the ER are regulated remains incomplete.
• Transcriptional and post-translational regulation may influence both ER-phagy and the unfolded protein response.
