Targeting redox signaling in the vascular wall: from basic science to clinical practice

Area of Science:

• Cardiovascular Biology
• Oxidative Stress Research
• Vascular Physiology

Background:

• Oxidative stress, driven by reactive oxygen species (ROS), is central to vascular homeostasis.
• ROS are generated by multiple sources within the vascular wall, including endothelial cells, smooth muscle cells, and inflammatory cells.
• While ROS act as signaling molecules, their overproduction causes cytotoxic effects and activates pro-atherogenic pathways.

Purpose of the Study:

• To explore the role of oxidative stress and ROS in vascular homeostasis and atherogenesis.
• To review therapeutic strategies aimed at regulating vascular redox signaling and intracellular ROS bioavailability.
• To identify the need for further research into effective anti-atherogenic treatments targeting redox pathways.

Main Methods:

• Literature review of oxidative stress mechanisms in the vascular wall.
• Analysis of ROS effects on vascular physiology and pathology.
• Evaluation of current and potential therapeutic interventions for redox signaling modulation.

Main Results:

• Excess ROS generation impairs vascular elasticity and mechanics, contributing to atherogenesis.
• Redox-sensitive pathways, including matrix metalloproteinases, are activated by ROS.
• Several therapeutic agents (statins, ACE inhibitors, etc.) show promise in targeting vascular redox signaling.

Conclusions:

• Regulating vascular redox signaling by targeting intracellular ROS is crucial for maintaining vascular health.
• Current therapeutic strategies show potential but require further investigation to confirm their efficacy in preventing atherosclerosis.
• Future research should focus on defining key vascular redox-sensitive pathways to develop targeted anti-atherosclerotic therapies.
