Immune defense against hepatotropic viruses such as hepatitis B (HBV) and hepatitis C (HCV) poses a major challenge for therapeutic approaches. Intrahepatic cytotoxic CD8 T cells that are crucial for an immune response against these viruses often become exhausted resulting in chronic infection. We elucidated the T cell response upon therapeutic vaccination in inducible transgenic mouse models in which variable percentages of antigen-expressing hepatocytes can be adjusted, providing mosaic antigen distribution and reflecting the varying viral antigen loads observed in patients...

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide. The initiation of protein translation is an important rate-limiting step in eukaryotes and is crucial in many viral infections. Eukaryotic translation initiation factors (eIFs) are involved in the initiation step of protein translation and are linked to the phosphatidylinositol-3-kinases PI3K/AKT/mTOR pathway. Therefore we aimed to investigate a potential role of eIFs in HCC. We herein report on the immunohistochemical expression of the various eIF subunits in 235 cases of virus-related human HCC...

Kupffer cells(KCs) largely found in the sinusoids are the macrophages which specifically reside in liver. KC is a crucial part of innate immune system, acting as scavenger and phagocyte. KCs and sinusoidal endothelial cells together form the first immune barrier of the portal system. Studies show that KCs can not only maintain homeostasis in immune response, but also facilitate the pathogenesis of type B and type C hepatitis through their antigen-presenting function and secretion of soluble mediators. KCs can express TLRs (Toll-like receptors), FasL, Programmed cell death ligand 1 (PD-L1) and secrete large amount of inflammatory factors to lead to the tolerant state of immune response toward HBV/HCV...

BACKGROUND AND AIMS: We measured the timing of HBV and HCV diagnoses relative to detection of decompensated cirrhosis (DC) and hepatocellular carcinoma (HCC) as an indicator of late hepatitis diagnosis. METHODS: HBV and HCV diagnoses were defined relative to the diagnosis of DC or HCC such that HBV/HCV diagnoses within two years prior, at the time of or after HCC or DC diagnosis were considered late. We performed multivariable logistic regression to assess factors associated with late HBV/HCV diagnoses among those with DC or HCC...

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the second leading cause of cancer mortality worldwide. Incidence rates of liver cancer vary widely between geographic regions and are highest in Eastern Asia and sub-Saharan Africa. In the United States, the incidence of HCC has increased since the 1980s. HCC detection at an early stage through surveillance and curative therapy has considerably improved the 5-year survival. Therefore, medical societies advocate systematic screening and surveillance of target populations at particularly high risk for developing HCC to facilitate early-stage detection...

BACKGROUND AND AIMS: Fatty liver is a common feature of different types of liver diseases. The sensitivity and specificity of ultrasonography for diagnosing fatty liver are variable. A semi-quantitative ultrasound score, i.e., the ultrasonographic fatty liver indicator (US-FLI), is closely associated with metabolic/histological variables in patients with nonalcoholic fatty liver disease (NAFLD). The main aims of this study were to assess the diagnostic performance of US-FLI in detecting varying degrees of histological steatosis, and to examine the association of US-FLI with metabolic/histological parameters in 352 biopsied patients with various chronic liver diseases (173 with hepatitis C [HCV], 23 with hepatitis B [HBV], 123 with NAFLD and 33 with other etiologies)...

Hepatitis C virus (HCV) infection is a global health problem with 150 million infected people worldwide. Liver can be greatly affected by changes in gut microbiota due to increased intestinal permeability with passage of microbial antigens into the liver through the portal circulation. The concept of "gut-liver" axis is important to understand the pathophysiology of several liver diseases. Several recent studies also revealed that an altered gut microbiota can be implicated in the pathogenesis of HCV-induced chronic liver disease (CHC)...
