Unbalanced Redox With Autophagy in Cardiovascular Disease

Area of Science:

• Biochemistry
• Cardiovascular Science
• Cell Biology

Background:

• Precise redox balance is vital for human health; imbalances contribute to disease.
• Oxidative stress and inflammation are implicated in cardiovascular disease (CVD) pathogenesis.
• Antioxidants show complex effects on CVD risk, suggesting pathway-specific actions.

Purpose of the Study:

• To review the relationship between redox balance and cardiovascular disease (CVD).
• To summarize the role of autophagy in redox balance and atherosclerosis.
• To discuss autophagy-stimulating therapies for CVD.

Main Methods:

• Literature review focusing on redox balance, oxidative stress, and CVD.
• Analysis of animal models and in vitro systems for CVD mechanisms.
• Examination of autophagy's role in cellular responses to atherogenic stress.

Main Results:

• Excessive oxidative stress promotes atherosclerotic plaque formation and inflammation.
• Antioxidants have varied effects on CVD risk, linked to pathway modulation.
• Autophagy protects against plaque formation by mitigating oxidative stress and inflammation.

Conclusions:

• Redox imbalance is a significant factor in CVD development.
• Autophagy plays a protective role in atherosclerosis by maintaining redox homeostasis.
• Targeting autophagy presents a promising therapeutic strategy for CVD.
