Stanford Researchers Identify Pathway Causing Heart Scarring

Stanford researchers have discovered an atypical GPCR signaling pathway linked to heart scarring, specifically involving the G-beta-gamma complex in fibroblast activation and scar-producing gene expression. Inhibiting G-beta-gamma signaling in mouse models reduced fibrosis and improved heart function, suggesting a potential new therapeutic target for heart disease. This finding could lead to novel treatments for a major health issue.
