Oxidative stress disrupts vascular microenvironmental homeostasis affecting the development of atherosclerosis

Area of Science:

• Cardiovascular Science
• Pathophysiology
• Molecular Biology

Background:

• Atherosclerosis is a chronic inflammatory cardiovascular disease driven by endothelial damage.
• Oxidative stress, resulting from excess oxygen free radicals, amplifies inflammation and vascular dysfunction.
• Reduced nitric oxide levels, critical for vascular homeostasis, are linked to atherosclerosis development.

Purpose of the Study:

• To investigate the role of oxidative stress in atherosclerosis formation within the vascular environment.
• To review potential therapeutic targets and pharmacological strategies for managing atherosclerosis.

Main Methods:

• Literature review focusing on the interplay between oxidative stress, inflammation, and endothelial dysfunction.
• Analysis of molecular mechanisms underlying oxidative stress-induced vascular damage.
• Examination of current and emerging pharmaceutical interventions.

Main Results:

• Oxidative stress initiates a detrimental cycle involving cytokine and chemokine release, disrupting vascular homeostasis.
• Damage to vascular endothelial cells and diminished nitric oxide bioavailability are direct consequences of oxidative stress.
• The vascular milieu significantly influences the progression of atherosclerosis under oxidative stress conditions.

Conclusions:

• Oxidative stress is a critical mediator in the pathogenesis of atherosclerosis.
• Targeting oxidative stress pathways and enhancing nitric oxide levels present promising therapeutic avenues for atherosclerosis treatment.
