Heart Cells Make Their Own Ghrelin: A Local Cardiac Ghrelin System

In VitroPreliminary evidence
The takeaway

Cardiomyocytes synthesize and secrete ghrelin with functional GHS-R expression, establishing a local cardiac ghrelin autocrine/paracrine system that may contribute to cardiac protection and remodeling.

Key finding

Cardiomyocytes expressed ghrelin mRNA and protein, secreted ghrelin into culture medium, and expressed functional GHS-R — establishing an autocrine/pa

What the researchers found

Cardiomyocytes expressed ghrelin mRNA and protein, secreted ghrelin into culture medium, and expressed functional GHS-R — establishing an autocrine/paracrine cardiac ghrelin system for local cardiac regulation and protection.

Why it matters

Advances understanding of ghrp, cardiovascular, receptor-signaling with translational implications.
