Abstract

BACKGROUND & AIMS: Viruses target innate immune pathways to evade host antiviral responses. Recent studies demonstrate a relationship between hepatitis B disease states and the host's innate immune response, although the mechanism of immunomodulation is unknown. In humans, the innate immune system recognizes pathogens via pattern recognition receptors such as the Toll-like receptors (TLR), initiating anti-inflammatory responses. TLR expression and pro-inflammatory cytokine production is reduced in hepatitis B e antigen (HBeAg)-positive patients following TLR stimulation. The aim of this study was to investigate interactions between TLR signaling pathways and the mature HBeAg protein localize..
