The endoplasmic reticulum (ER) is central to protein synthesis, folding and secretion. A study now shows that ageing is characterized by a striking loss of ER mass and remodelling of the ER structure. This shift is driven by tissue-specific ER-phagy, and may contribute to age-related loss of proteostasis.
