A new report from Yale University explores the interaction between neutrophils and hepatocytes in liver diseases. Neutrophils are white blood cells that typically use proteases to neutralize foreign substances, but they can also have nondestructive effects on tissue remodeling and metabolism. The researchers discovered that neutrophils can insert elastase-containing granules into hepatocytes, which selectively degrade intracellular calcium channels and reduce cell proliferation without causing harm. This mechanism was observed in patients with alcohol-associated hepatitis and confirmed in mouse models. The study highlights a previously unrecognized role for neutrophils in regulating epithelial calcium signaling in the liver. [Extracted from the article]
