Frontiers in neuroscience, 2017•frontiersin.orgNeurodegenerative diseases often have multifactorial causes and are progressive diseases.
Some are inherited while others are acquired, and both vary greatly in onset and severity.
Impaired endoplasmic reticulum (ER) proteostasis, involving Ca 2+ signaling, protein
synthesis, processing, trafficking, and degradation, is now recognized as a key risk factor in
the pathogenesis of neurological disorders. Lipidostasis involves lipid synthesis, quality
control, membrane assembly as well as sequestration of excess lipids or degradation of …

Neurodegenerative diseases often have multifactorial causes and are progressive diseases. Some are inherited while others are acquired, and both vary greatly in onset and severity. Impaired endoplasmic reticulum (ER) proteostasis, involving Ca2+ signaling, protein synthesis, processing, trafficking, and degradation, is now recognized as a key risk factor in the pathogenesis of neurological disorders. Lipidostasis involves lipid synthesis, quality control, membrane assembly as well as sequestration of excess lipids or degradation of damaged lipids. Proteostasis and lipidostasis are maintained by interconnected pathways within the cellular reticular network, which includes the ER and Ca2+ signaling. Importantly, lipidostasis is important in the maintenance of membranes and luminal environment that enable optimal protein processing. Accumulating evidence suggest that the loss of coordinate regulation of proteostasis and lipidostasis has a direct and negative impact on the health of the nervous system.
