Hepatocyte protection

"Hepatocyte protection" refers to the therapeutic or physiological strategies that prevent or reduce damage to hepatocytes (the principal cells of the liver) during injury, disease, or drug exposure. This concept encompasses mechanisms that inhibit apoptosis and necrosis, reduce oxidative stress, enhance cellular defense and repair processes, and modulate immune-mediated injury. Protective mechanisms may involve upregulation of anti-apoptotic proteins (Bcl-2, Bcl-xL), activation of survival signaling pathways (like IL-6/STAT3 or PI3K/Akt), scavenging of damaging reactive oxygen species, and modulation of inflammatory or immune responses. The objective of hepatocyte protection underlies many therapeutic approaches for acute liver failure, drug-induced liver injury, viral hepatitis, and chronic liver diseases such as nonalcoholic steatohepatitis and fibrosis. It is a **therapeutic goal** rather than a molecule, receptor, or specific drug target.
