Adipokines and the cardiovascular system: mechanisms mediating health and disease

Area of Science:

• Cardiovascular Biology
• Endocrinology
• Obesity Research

Background:

• Adipose tissue functions as an endocrine organ, secreting adipokines like adiponectin and leptin.
• Obesity alters adipose tissue depots and their distinct adipokine secretion profiles.
• Adipokines are implicated in both maintaining cardiovascular health and mediating disease development.

Purpose of the Study:

• To review the role of key adipokines in cardiovascular system maintenance.
• To elucidate mechanisms by which adipokines mediate cardiovascular disease in obesity.
• To examine adipokine interactions with specific cardiovascular cell types.

Main Methods:

• Literature review focusing on adipokines secreted by adipocytes.
• Analysis of adipokine effects on endothelial progenitor cells, endothelial cells, vascular smooth muscle cells, pericytes, cardiomyocytes, and cardiac fibroblasts.
• Discussion of adipokine-induced angiogenesis and inflammation in cardiovascular disease.

Main Results:

• Seven specific adipokines (adiponectin, leptin, resistin, chemerin, omentin, vaspin, visfatin) were analyzed.
• Adipokines exhibit diverse effects on cardiovascular cells, influencing angiogenesis and inflammation.
• Obesity-associated changes in adipokine profiles contribute to cardiovascular pathology.

Conclusions:

• Adipokines significantly impact cardiovascular health, with obesity exacerbating negative effects.
• Understanding adipokine actions is crucial for developing strategies against obesity-related cardiovascular disease.
• Targeting specific adipokines may offer therapeutic potential for cardiovascular conditions.
