[New mechanisms of chronic kidney disease-associated vascular calcification]

Area of Science:

• Nephrology and Cardiovascular Science
• Cell Biology and Molecular Mechanisms

Background:

• Vascular calcification significantly increases cardiovascular disease (CVD) morbidity and mortality in chronic kidney disease (CKD) patients, posing a substantial health and economic burden.
• CKD-associated vascular calcification is an active ectopic osteogenesis process involving multiple cell types.
• Understanding the pathogenesis and developing interventions for CKD-related vascular calcification is critical.

Approach:

• This review synthesizes current knowledge on the mechanisms and technologies related to CKD-associated vascular calcification.
• It examines the role of vascular smooth muscle cells (VSMCs) in the osteogenic differentiation and matrix vesicle formation leading to calcification.
• The review specifically discusses the potential involvement of the myokine Irisin in CKD-associated vascular calcification.

Key Points:

• Vascular smooth muscle cells (VSMCs) differentiate into osteogenic cells in pro-calcific environments.
• VSMCs secrete matrix vesicles, initiating calcium and phosphorus crystal deposition.
• The myokine Irisin is highlighted for its potential role in CKD-associated vascular calcification.

Conclusions:

• CKD-associated vascular calcification is a complex process driven by VSMC osteogenic differentiation and matrix vesicle activity.
• Exploring novel therapeutic targets, such as Irisin, is essential for managing vascular calcification in CKD.
• Further research into Irisin's function could lead to new interventions for cardiovascular complications in CKD patients.
