摘要

The liver is a crucial organ in the human body and is responsible for various functions, including digestion, detoxification, metabolism, and immune response. Proper hepatic function is vital for maintaining systemic homeostasis, and dysregulation of liver signaling pathways contributes to various diseases. Recepteur d’Origine Nantais (RON) is a transmembrane receptor tyrosine kinase that is activated by macrophage-stimulating protein (MSP) and coordinates cell fate decisions through the activation of downstream signaling cascades. As the predominant source of MSP in humans, the liver establishes a liver-specific MSP‒RON autocrine‒paracrine signaling axis that contributes to hepatic regeneration, metabolism, and immune functions. Extensive research has demonstrated that MSP-RON signaling is involved in steatotic liver diseases, hepatitis, cirrhosis, cholestatic liver disease, and liver cancer, highlighting the importance of RON in the development of liver diseases. This review demonstrates the role of the MSP-RON pathway both in maintaining liver homeostasis and in driving disease onset and progression while exploring its signaling mechanisms and therapeutic potential for liver disorders.
