Targeting senescent cells to attenuate cardiovascular disease progression

Area of Science:

• Cardiovascular Science
• Cellular Aging
• Gerontology

Background:

• Cardiovascular disease (CVD) is a leading cause of morbidity and mortality, particularly in aging populations.
• Current pharmacological treatments for age-related CVD often yield suboptimal results, necessitating novel therapeutic approaches.
• Accumulation of senescent cardiovascular cells is observed in aged and diseased hearts, suggesting their detrimental role in cardiovascular function.

Purpose of the Study:

• To review the evidence linking senescent cells to cardiovascular aging and CVD.
• To explore the molecular mechanisms of cardiovascular cell senescence.
• To discuss senescent cell eradication as a therapeutic strategy for CVD.

Main Methods:

• Literature review of studies on cardiovascular cell senescence.
• Analysis of molecular mechanisms underlying cellular senescence in the cardiovascular system.
• Evaluation of therapeutic strategies targeting senescent cells.

Main Results:

• Senescent cardiovascular cells exhibit irreversible cell cycle arrest and a senescence-associated secretory phenotype.
• These senescent cells contribute to cardiovascular aging and the progression of CVD.
• Targeted eradication of senescent cells via apoptosis or immune-mediated mechanisms shows therapeutic potential.

Conclusions:

• Senescent cardiovascular cells are key contributors to cardiovascular aging and disease.
• Targeting senescent cells represents a promising novel therapeutic avenue for CVD prevention and treatment.
• Further research into senolytic therapies is warranted for effective CVD management.
