[Inflammatory process in atherogenesis: new facts about old flame]

Area of Science:

• Cardiovascular Science
• Immunology
• Metabolic Disorders

Context:

• Atherosclerosis is a complex, chronic inflammatory disease impacting vascular, immune, and metabolic systems.
• Endothelial dysfunction is a critical early event in atherogenesis, involving inflammatory mediators.
• The pathogenesis of atherosclerosis involves a cycle of inflammation, lipoprotein modification, and cellular responses.

Purpose:

• To elucidate the role of inflammation in the initiation and progression of atherosclerosis.
• To highlight the involvement of inflammatory mediators in key stages of atherogenesis, from endothelial dysfunction to plaque rupture.

Summary:

• Inflammation drives atherosclerosis through endothelial dysfunction, foam cell formation, and the activation of monocytes and macrophages.
• Mediators of inflammation contribute to the development of atherosclerotic lesions, including fatty streaks, transitory lesions, fibrotic plaques, and complex lesions.
• The inflammatory process is intrinsically linked to the development and rupture of atherosclerotic plaques.

Impact:

• Provides a comprehensive understanding of inflammation's role in atherosclerosis, crucial for developing targeted therapies.
• Emphasizes the significance of inflammatory pathways in the initiation, progression, and clinical presentation of the disease.
• Highlights the need for further research into inflammatory mechanisms for effective atherosclerosis management and prevention.
