Pre-S deletion and complex mutations of hepatitis B virus related to advanced liver disease in HBeAg-negative patients.

abstract：BACKGROUND AND AIMS:Hepatic lymphocytes are composed mainly of natural killer (NK) cells and NKT cells, which play key roles in innate immune responses against pathogens and tumors in the liver. This report analyzes the effects of activation of innate immunity by viral infection or the toll-like receptor 3 (TLR3) ligan...
