International Review of Cell and Molecular Biology, Volume 350, covers all aspects of endoplasmic reticulum (ER) biology. With its multiple cellular functions, including ion storage as well protein folding, trafficking and secretion, the regulation of homeostasis within the ER is crucial to organismal health. New sections in this updated volume include DAMP emission upon ER stress, Protein misfolding disordersm Type I interferon response and ER stress, ER and autophagosome biogenesis, Mitochondria-associated membranes, ER calcium signaling in excitable cells, and ER in viral infections. - Summarizes endoplasmic reticulum-related pathologies - Gives an update on the immunological aspects of ER-stress - Brings the links between ER homeostasis and autophagy
