Abstract
This review aims to summarize recent research using animal models, cell models, and human data regarding the role of complement in liver disease. Complement is part of the innate immune system and was initially characterized for its role in control of pathogens. However, evidence now indicates that complement also plays an important role in the response to cellular injury that is independent of pathogens. The liver is the main organ responsible for producing circulating complement. In response to liver injury, complement is activated and likely plays a dual role, both contributing to and protecting from injury. In uncontrolled complement activation, cell injury and liver inflammation occur, contributing to progression of liver disease. Complement activation is implicated in the pathogenesis of multiple liver diseases, including alcohol-associated liver disease, metabolic dysfunction-associated steatotic liver disease, fibrosis and cirrhosis, hepatocellular carcinoma, and autoimmune hepatitis. However, the mechanisms by which complement is overactivated in liver diseases are still being unraveled.
期刊介绍：
Seminars in Liver Disease is a quarterly review journal that publishes issues related to the specialties of hepatology and gastroenterology.
As the premiere review journal in the field, Seminars in Liver Disease provides in-depth coverage with articles and issues focusing on topics such as cirrhosis, transplantation, vascular and coagulation disorders, cytokines, hepatitis B & C, Nonalcoholic Steatosis Syndromes (NASH), pediatric liver diseases, hepatic stem cells, porphyrias as well as a myriad of other diseases related to the liver. Attention is also given to the latest developments in drug therapy along with treatment and current management techniques. Seminars in Liver Disease publishes commissioned reviews. Unsolicited reviews of an exceptional nature or original articles presenting remarkable results will be considered, but case reports will not be published.
