Abstract
Interorgan crosstalk refers to the bidirectional communication and interaction between different organs in the body. It plays a crucial role in maintaining metabolic homeostasis and is essential for proper physiological function. Dysregulation of organ crosstalk has been associated with the development of various metabolic disorders, including metabolic dysfunction-associated steatotic liver disease (MASLD). MASLD is a growing health issue worldwide, affecting approximately 30% of the global population. There has been a growth in literature to address the dysregulated crosstalk between multiple extrahepatic organs and the liver; thus, many striking findings have been published. However, the underlying mechanisms remain largely obscure. In this study, we focused on the perspective of circulating proteins, metabolites, neuroendocrine signals, and extracellular vesicles, summarizing systematically how they affect extrahepatic organs and the liver in the pathogenesis of MASLD. Furthermore, particular attention is placed on the potential novel therapeutic strategies.
