Liver injury is a research area that focuses on understanding the causes, mechanisms, and consequences of damage to the liver. This damage can be caused by various factors such as alcohol abuse, viral infections, autoimmune diseases, toxins, and medications. Research in this area aims to identify biomarkers of liver injury, develop new treatments for liver diseases, and improve our understanding of the liver's regenerative capacity. Studying liver injury is crucial for preventing and treating liver diseases such as cirrhosis, hepatitis, and liver cancer.
