Hepatitis B, a global health concern caused by the hepatitis B virus (HBV), infects nearly 2 billion individuals worldwide, as reported World Health Organization (WHO). HBV, hepatotropic DNA virus, predominantly targets and replicates within hepatocytes. Those carrying are at increased risk of liver cirrhosis hepatocellular carcinoma, resulting in 900,000 fatalities annually. The HBV X protein (HBx), encoded virus’s open reading frame x, plays key role its virulence. This is integral to viral replication, immune modulation, cancer progression. Despite significance, precise molecular mechanisms underlying HBx remain elusive. review investigates protein’s roles interferon signaling regulation, carcinoma By understanding complex interactions between host mediated HBx, we aim establish solid foundation for future research development HBx-targeted therapeutics.

In this study, we aimed investigate regulatory effects of macrophages on marker interferon-stimulated genes (ISGs) expressions hepatocytes. This study was performed HBV-replicating HepG2.2.15 human monocyte-derived (MDMs). We found that exposure an acetaldehyde-generating system (AGS) increased RNA, DNA, cccDNA suppressed activation ISGs, APOBEC3G, ISG15, OAS1. Supernatants collected from IFNα-activated MDMs decreased levels induced ISG AGS-treated untreated HepG2.215 cells.
