Abstract

The endoplasmic reticulum (ER) is a membranous intracellular organelle and the first compartment of the secretory pathway. As such, the ER contributes to the production and folding of approximately one-third of cellular proteins, and is thus inextricably linked to the maintenance of cellular homeostasis and the fine balance between health and disease. Specific ER stress signalling pathways, collectively known as the unfolded protein response (UPR), are required for maintaining ER homeostasis. The UPR is triggered when ER protein folding capacity is overwhelmed by cellular demand and the UPR initially aims to restore ER homeostasis and normal cellular functions. However, if this fails, then the UPR triggers cell death. In this review, we provide a UPR signalling-centric view of ER functions, from the ER's discovery to the latest advancements in the understanding of ER and UPR biology. Our review provides a synthesis of intracellular ER signalling revolving around proteostasis and the UPR, its impact on other organelles and cellular behaviour, its multifaceted and dynamic response to stress and its role in physiology, before finally exploring the potential exploitation of this knowledge to tackle unresolved biological questions and address unmet biomedical needs. Thus, we provide an integrated and global view of existing literature on ER signalling pathways and their use for therapeutic purposes.

  • Various investigations have shown that nutraceuticals are capable of fulfilling neuroprotective functions on molecular mechanisms that trigger Alzheimer's disease, acting as antioxidants or anti-neuroinflammatory drugs, affecting aggregation of β amyloid peptides, hyperphosphorylation of Tau protein, and decrease of acetylcholine in cholinergic neurons.

    “Various investigations have shown that nutraceuticals are capable of fulfilling neuroprotective functions on molecular mechanisms that trigger AD, acting as antioxidants or anti-neuroinflammatory drugs, taking effect on the aggregation of β amyloid peptides, the hyperphosphorylation of the Tau protein and the decrease of the neurotransmitter ACh in cholinergic neurons [70,71,72]”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
