Cirrhosis is a disease that can be triggered by various factors such as alcohol abuse, viral infections, NAFLD, or obesity and it is considered the final stage of liver disease. After a liver injury, cell death is induced on damaged triggering the release of pro-inflammatory signals that activate the immune cells present in the liver parenchyma. These, in turn, activate other cells responsible for liver tissue regeneration, such as HSCs. However, during cirrhosis, the tissue regeneration mechanism becomes dysregulated due to the increased magnitude of the inflammatory response, leading to a state of excessive extracellular matrix production by HSCs known as fibrosis. LSECtin is a C-type lectin found in liver endothelium and has been involved in inflammation regulation. As its expression is reduced in cirrhotic human and mouse livers it stands out as an interesting target for both the diagnosis and treatment of chronic liver disease. Additionally, it has been suggested that it may act as a repressor of certain lymphocyte subpopulations that promote liver inflammation. In this study, we evaluated the immunomodulatory role of LSECtin using a mouse model of cirrhosis by carbon tetrachloride (CCl4) oral administration. Specifically, damage has been evaluated in wild type mice and mice that overexpress LSECtin. We conclude that LSECtin plays a key role in the development of cirrhosis modulating proinflammatory lymphocyte populations, suggesting its potential as a therapeutic target in cirrhosis.
