PPARS in inflammation, atherosclerosis and thrombosis

Area of Science:

• Molecular biology
• Cardiovascular research
• Metabolic diseases

Background:

• Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors regulating key metabolic and inflammatory pathways.
• PPARalpha and PPARgamma subtypes have distinct roles in lipid metabolism, glucose homeostasis, and adipogenesis.
• PPARs are expressed in atherosclerotic lesions and influence inflammatory cell recruitment and lipid handling.

Purpose of the Study:

• To review the multifaceted roles of PPARalpha and PPARgamma in atherosclerosis.
• To elucidate the impact of PPARs on immunoregulation, vascular inflammation, and thrombosis.
• To highlight the therapeutic potential of PPARs in cardiovascular disease.

Main Methods:

• Literature review focusing on PPARalpha and PPARgamma functions in atherosclerosis.
• Analysis of gene expression and cellular mechanisms regulated by PPARs.
• Examination of pharmacological and natural activators of PPARs.

Main Results:

• PPARalpha promotes fatty acid oxidation, while PPARgamma enhances adipogenesis and lipid storage.
• Both PPAR subtypes improve glucose homeostasis and modulate inflammatory cell behavior in atherosclerotic lesions.
• PPARs regulate macrophage lipid metabolism via scavenger receptors and reverse cholesterol transport.
• PPARs influence thrombogenicity, impacting plaque stability and rupture risk.

Conclusions:

• PPARs are critical regulators of atherosclerosis, impacting both metabolic and vascular aspects.
• Targeting PPARalpha and PPARgamma offers potential therapeutic strategies for cardiovascular diseases.
• Further research into PPAR-mediated immunoregulation and thrombosis is warranted.
