The Liver’s Secret Signals: How Hepatokines Govern Kidney Scarring
A new review in Nature Reviews Nephrology highlights the emerging role of hepatokines—liver-derived signaling proteins—in regulating kidney fibrosis. This organ-to-organ communication represents a significant shift in understanding the pathogenesis of chronic kidney disease, moving beyond a kidney-centric view. The research suggests that metabolic and inflammatory signals from a diseased liver, such as in non-alcoholic fatty liver disease (NAFLD) or cirrhosis, can directly promote fibrotic processes in the kidneys, potentially explaining the high co-occurrence of liver and kidney disorders.
Why it might matter to you: For gastroenterologists and hepatologists, this underscores a systemic dimension to liver disease management, where hepatic health directly impacts extra-hepatic organs like the kidneys. It suggests that monitoring for and managing early kidney fibrosis should be integral to the care of patients with advanced liver conditions, particularly those with metabolic dysfunction. This cross-disciplinary insight could inform more holistic treatment strategies and the development of novel biomarkers or therapies targeting these hepatokine pathways.
