Endoplasmic reticulum (ER) stress contributes to endothelial dysfunction (ED) and cardiovascular disease (CVD). Targeting ER stress may offer a novel therapeutic strategy to prevent vascular damage and slow the progression of cardiovascular events.
Area of Science:
- Cardiovascular Science
- Cellular Biology
- Pathophysiology
Background:
- Endoplasmic reticulum (ER) stress is linked to cardiovascular disease (CVD) pathogenesis.
- Endothelial dysfunction (ED) is a primary factor in CVD development.
- ER stress is a significant contributor to vascular damage caused by metabolic risk factors.
Purpose of the Study:
- To review experimental findings on ER stress-related endothelial dysfunction.
- To elucidate the mechanisms linking ER stress and ED.
- To highlight the role of ER stress in cardiovascular pathology.
Main Methods:
- Review of experimental studies on ER stress and ED.
- Analysis of mechanisms underlying ER stress-induced vascular damage.
- Examination of evidence from animal models and human endothelial cells.
Main Results:
- Various risk factors (hyperhomocysteinemia, hyperlipidemia, hyperglycemia, inflammation) induce ED via amplified ER stress.
- ER stress mediates vascular damage, exacerbating inflammation and oxidative stress.
- An unchecked ER stress response is central to ED and CVD pathogenesis.
Conclusions:
- ER stress is a key mediator in the development of endothelial dysfunction and cardiovascular disease.
- Therapeutic strategies targeting ER stress may prevent vascular damage.
- Counteracting ER stress could slow the progression from ED to cardiovascular events.

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...

Smooth Endoplasmic Reticulum
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...
