Endoplasmic reticulum (ER) stress triggers the unfolded protein response (UPR), which can lead to cell death or survival. ER stress and inflammation interact, worsening cellular dysfunction in many diseases.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- The endoplasmic reticulum (ER) is vital for cellular homeostasis and protein folding.
- ER stress, a disruption in protein folding, activates the unfolded protein response (UPR).
- The UPR's outcome (homeostasis restoration or apoptosis) depends on stress factors and cell type.
Purpose of the Study:
- To explore the intricate relationship between ER stress and inflammation.
- To understand how these pathways interact in various human pathologies.
- To identify potential therapeutic targets for diseases involving ER stress and inflammation.
Main Methods:
- Review of existing literature on ER stress, UPR, and inflammatory signaling.
- Analysis of shared molecular regulators and effectors between ER stress and inflammation.
- Examination of disease models where ER stress and inflammation are implicated.
Main Results:
- ER stress and inflammatory signaling pathways share common regulators and effectors.
- A detrimental cycle exists where ER stress and inflammation exacerbate each other, leading to cellular dysfunction and apoptosis.
- This interplay is observed across diverse pathologies, including autoimmune, infectious, neurodegenerative, and metabolic disorders.
Conclusions:
- The interaction between ER stress and inflammation is a significant factor in cellular dysfunction and disease pathogenesis.
- Understanding this crosstalk is crucial for developing novel therapeutic strategies.
- Further research into the underlying biochemical and cellular mechanisms is warranted to target these interconnected pathways effectively.

Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...

The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
