Abstract

Cardiovascular disease (CVD) remains a leading cause of morbidity and mortality globally, prompting the investigation of novel therapeutic targets. Progranulin (PGRN), a glycoprotein initially associated with neurodegenerative disorders, has emerged as a critical protective agent in cardiovascular health. Recent studies indicate that PGRN exerts its protective effects through various mechanisms, including the modulation of inflammatory pathways, enhancement of mitochondrial function, and promotion of vascular integrity. By engaging with key signaling pathways, such as PI3K/Akt, NF-κB and Wnt/β-catenin, PGRN mitigates oxidative stress and fosters an environment conducive to cardiac repair following ischemic injury. Furthermore, PGRN’s role in lipid metabolism and vascular smooth muscle cell behavior highlights its complexity in influencing atherogenesis and vascular homeostasis. This review synthesizes current knowledge regarding PGRN’s protective mechanisms in CVD, emphasizing its potential as a therapeutic target and paving the way for innovative approaches to prevent and treat cardiovascular diseases, ultimately improving patient outcomes in this critical area of public health.
