Endothelial Dysfunction in Obesity-Induced Inflammation: Molecular Mechanisms and Clinical Implications

Area of Science:

• Metabolic Syndrome
• Cardiovascular Health
• Inflammation Biology

Background:

• Obesity, characterized by excessive fat deposition, is a growing global health concern affecting all age groups.
• It disrupts normal metabolic processes and is linked to various metabolic syndromes.
• Obesity promotes a proinflammatory state through the release of inflammatory mediators from adipose tissue.

Purpose of the Study:

• To discuss the role of endothelial dysfunction in obesity-related cardiovascular diseases.
• To explore the link between obesity-induced inflammation and endothelial dysfunction.
• To highlight the importance of managing obesity and inflammation for cardiovascular health.

Main Methods:

• Review of inflammatory mediators secreted during obesity, including IL-6, TNF-α, and MCP-1.
• Analysis of the impact of obesity on adipose tissue function and hormone release.
• Examination of endothelial cell responses to inflammation and MCP-1 stimulation.

Main Results:

• Obesity leads to the secretion of inflammatory mediators that reduce adiponectin and promote inflammation.
• Adipose tissue in obesity releases hormones and cytokines that negatively impact metabolic processes and endothelial function.
• Inflammation and MCP-1 stimulation in endothelial cells activate adhesion molecules, promoting leukocyte transmigration and atherogenesis.

Conclusions:

• Endothelial dysfunction is a key factor in the progression of cardiovascular diseases in obesity.
• The link between obesity, inflammation, and endothelial dysfunction is established through proinflammatory cytokine overexpression and reduced anti-inflammatory markers.
• Inhibiting inflammatory mechanisms and controlling obesity are crucial for mitigating cardiovascular risks.
