Hepatitis C virus (HCV) alters mitochondrial dynamics associated with persistent viral infection and suppression of innate immunity. Mitochondrial dysfunction is also a pathologic feature of direct-acting antiviral (DAA) treatment. Despite the high efficacy of DAAs, their treatment of patients with chronic hepatitis C in interferon-sparing regimens occasionally produces undesirable side effects such as fatigue, migraine and other conditions, which may be linked to mitochondrial dysfunction. Here we show that clinically prescribed DAAs, including Sofosbuvir, affect mitochondrial dynamics...

BACKGROUND & AIM: Statin decreased the risk of decompensation and mortality in veteran patients with cirrhosis due to hepatitis C virus (HCV). Whether this beneficial effect can be extended to cirrhosis in general population or cirrhosis with other causes, such as hepatitis B virus (HBV) infection and alcohol, remains unknown. Statin also decreased the risk of hepatocellular carcinoma (HCC) in patients with chronic HBV and HCV infection. It is unclear whether the effect can be observed in patients already with cirrhosis...

Hepatitis C virus (HCV) mediated chronic liver disease is a serious health problem around the world, and often causes fibrosis/cirrhosis, and hepatocellular carcinoma (HCC). The mechanism of liver disease progression during HCV infection is still unclear, although inflammation is believed to be an important player in disease pathogenesis. We previously reported that macrophages including Kupffer cells exposed to HCV induce proinflammatory cytokines. These secreted cytokines may activate hepatic stellate cells (HSCs) towards fibrosis...

Use of Adeno-associated viral (AAV) vectors for liver-directed gene therapy has shown considerable success, particularly in patients with severe hemophilia B. However, the high vector doses required to reach therapeutic levels of transgene expression caused liver inflammation in some patients that selectively destroyed transduced hepatocytes. We hypothesized that such detrimental immune responses can be avoided by enhancing the efficacy of AAV vectors in hepatocytes. Because autophagy is a key liver response to environmental stresses, we characterized the impact of hepatic autophagy on AAV infection...

α1 -antitrypsin (AAT) deficiency is one of the most common genetic disorders and the liver disease due to the Z mutant of α1 -antitrypsin (ATZ) is a prototype of conformational disorder due to misfolding of protein with consequent aberrant intermolecular protein aggregation. In the present study, we found that livers of PiZ transgenic mice expressing the human ATZ have altered expression of a network of hepatocyte transcriptional factors including HNF4-α, that is early downregulated and induces a transcriptional repression of ATZ expression...

We report a case of dramatic systemic inflammatory symptoms and biochemical signs of inflammatory related to multiple hepatic adenomas that completely resolved after cessation of the oral contraceptive pill and associated adenoma regression. This represents the first case of such dramatic symptoms to resolve after estrogen withdrawal alone. This article is protected by copyright. All rights reserved.

Adjuvant interferon-α (IFN-α) therapy is used to control certain types of cancer in clinics. For hepatocellular carcinoma (HCC), IFN-α therapy is effective in only a subgroup of HCC patients, therefore identifying biomarkers to predict the response to IFN-α therapy is of high significance and clinical utility. As the induced IFN-stimulated genes (ISGs) expression following IFN-α treatment plays pivotal roles in IFN-α effects, we screened ISGs expression in HCC tissues and found several ISGs were significantly decreased in HCC...

Hepatitis B virus (HBV) infection shows significant gender-related differences in pathogenesis, disease progression, and development of hepatocellular carcinoma. The gender-associated differences in HBV replication and viral protein levels may be associated with distinct HBV-specific immune responses in the host. In the present study, we examined the impact of gender on HBV-specific immune responses in two different mouse models representing transient and persistent hepadnaviral infection; hydrodynamic injection (HI) with the HBV genome mimicked acute HBV infection, whereas the efficacy of therapeutic vaccination was studied in the woodchuck hepatitis virus (WHV) transgenic (Tg) mouse model...

Acetaminophen (APAP) overdose is a leading cause of acute liver failure worldwide, in which mitochondrial DNA (mtDNA) released by damaged hepatocytes activates neutrophils via the binding of TLR9, further aggravating liver injury. Here, we demonstrated that mtDNA/TLR9 also activates a negative feedback pathway via the induction of microRNA-223 (miR-223) to limit neutrophil over-activation and liver injury. After injection of APAP in mice, levels of miR-223, the most abundant miRNAs in neutrophils, were highly elevated in neutrophils...

REVIEW
Christine M Hunt, Julie I Papay, Vid Stanulovic, Arie Regev
Drug induced hepatocellular injury is identified internationally by ALT 5x upper limits normal (ULN) appearing within 3 months of drug initiation, after alternative causes are excluded. Upon withdrawing the suspect drug, ALT generally decreases by 50% or more. With drug readministration, a positive rechallenge has recently been defined by an ALT 3-5xULN or greater. Nearly 50 drugs are associated with positive rechallenge after drug-induced liver injury (DILI): antimicrobials, central nervous system, cardiovascular and oncology therapeutics...
