Vascular endothelial senescence: from mechanisms to pathophysiology

Area of Science:

• Cellular biology
• Vascular biology
• Gerontology

Background:

• Cellular senescence is a stress-induced, permanent growth arrest observed in mammalian cells.
• This phenomenon has been studied in cell culture and increasingly identified in vivo across various tissues.

Purpose of the Study:

• To review the evidence for cellular senescence in the vascular endothelium.
• To discuss factors influencing endothelial cell senescence.
• To examine the implications of endothelial senescence for vascular diseases.

Main Methods:

• Literature review of studies on cellular senescence.
• Analysis of mechanisms regulating endothelial cell replicative capacity.
• Examination of the senescent phenotype in vascular contexts.

Main Results:

• Evidence suggests cellular senescence occurs in the vascular endothelium.
• Factors modulating endothelial cell proliferation and senescence onset are identified.
• The senescent endothelial cell phenotype presents potential roles in vascular pathology.

Conclusions:

• Cellular senescence is a relevant biological process in the vascular endothelium.
• Understanding endothelial senescence mechanisms is crucial for comprehending vascular disease progression.
• Further research into endothelial senescence could reveal therapeutic targets for vascular conditions.
