Perspectives on C-Type Natriuretic Peptide in Cardiometabolic Disease

Area of Science:

• Cardiovascular Biology
• Endocrinology
• Vascular Medicine

Background:

• C-type natriuretic peptide (CNP) is primarily expressed in the vascular endothelium, functioning as a local regulator of vascular integrity.
• CNP signaling occurs via a specific receptor, distinct from cardiac natriuretic peptides (ANP, BNP), allowing for targeted interventions.
• The CNP system remains an underappreciated therapeutic target for cardiometabolic diseases and hypertension.

Purpose of the Study:

• To highlight the CNP system as a potential therapeutic target for preventing cardiovascular and metabolic diseases.
• To emphasize the unique signaling pathway of CNP, enabling targeted interventions without affecting cardiac natriuretic peptides.
• To encourage further research using human in vitro/ex vivo models, experimental approaches, and cohort data.

Main Methods:

• Review of existing literature on CNP expression, signaling, and function.
• Analysis of CNP's distinct receptor pathway compared to ANP and BNP.
• Discussion of potential therapeutic strategies targeting the CNP system.

Main Results:

• CNP functions as a local vascular factor, not a systemic hormone.
• CNP's unique signaling pathway allows for specific therapeutic targeting.
• The CNP system presents a promising avenue for early intervention in cardiometabolic diseases.

Conclusions:

• The CNP system is a viable and unique target for therapeutic intervention in cardiometabolic disease, hypertension, and diabetes.
• Targeting CNP can help prevent complications and heart failure by supporting vascular integrity.
• Further investigation using human-relevant models and data is crucial to realize the therapeutic potential of CNP.
