J Viral Hepat 2019 Apr 22. Epub 2019 Apr 22.

Liver Research Unit, Chang Gung Memorial Hospital, Chang Gung University College of Medicine, Taipei, Taiwan.

Cessation of nucleos(t)ide analogue (Nuc) therapy in HBeAg-negative patients may increase HBsAg loss rate in patients with sustained remission (SR) and non-retreated clinical relapsers (CR). To investigate and compare the HBsAg kinetics from end of treatment (EOT) to HBsAg loss in these patients, serial serum samples after EOT from 36 SR and 12 CR with HBsAg loss (study group) and an 1:1 matched control who remained HBsAg seropositive (control group) were assayed retrospectively for quantitative HBsAg (qHBsAg). The results showed that study group SR and CR had comparable EOT features except the SR which had lower EOT qHBsAg (67. Read More

In Vitro Resistance Profile of Hepatitis C Virus NS5A Inhibitor Velpatasvir in Genotypes 1 to 6.

J Viral Hepat 2019 Apr 22. Epub 2019 Apr 22.

Gilead Sciences, Foster City, California, USA.

Velpatasvir is a pan-genotypic hepatitis C virus (HCV) NS5A inhibitor which is used with sofosbuvir for treatment of infection with HCV genotypes 1 to 6. In vitro resistance studies were performed to characterize NS5A changes that might also confer reduced velpatasvir susceptibility in vivo. Resistance selection studies using HCV replicon cells for subtypes 1a, 1b, 2a, 2b, 3a, 4a, 5a, and 6a identified NS5A resistance-associated substitutions (RASs) at nine positions, most often 28M/S/T, 31F/I/M/P/V and 93D/H/N/S.

Discovery of hit molecules targeting allosteric site of hepatitis C virus NS5B polymerase.

J Biomol Struct Dyn 2019 Apr 21:1-16. Epub 2019 Apr 21.

b Excelra Knowledge Solutions Pvt Ltd , NSL-SEZ , Uppal, Hyderabad - 500 039 , India.

Nonstructural protein 5B (NS5B), the RNA-dependent RNA polymerase of Hepatitis C Virus (HCV) plays a key role in viral amplification and is an attractive and most explored target for discovery of new therapeutic agents for Hepatitis C. Though safe and effective NS5B inhibitors were launched in 2013 (Sovaldi) and 2014 (Harvoni, Viekira Pak), the high price tags of these medications limit their use among poor people in developing countries. Hence, still there exists a need for cost-effective and short duration anti-HCV agents especially those targeting niche patient population who were non-respondent to earlier therapies or with comorbid conditions.

Missing the Match Might Not Cost You the Game: Primer-Template Mismatches Studied in Different Hepatitis A Virus Variants.

Food Environ Virol 2019 Apr 19. Epub 2019 Apr 19.

European Union Reference Laboratory (EURL) for Foodborne Viruses, National Food Agency, Hamnesplanaden 5, 453 23, Uppsala, Sweden.

Mismatches between template sequences and reverse transcription (RT) or polymerase chain reaction (PCR) primers can lead to underestimation or false negative results during detection and quantification of sequence-diverse viruses. We performed an in silico inclusivity analysis of a widely used RT-PCR assay for detection of hepatitis A virus (HAV) in food, described in ISO 15216-1. One of the most common mismatches found was a single G (primer) to U (template) mismatch located at the terminal 3'-end of the reverse primer region. Read More

Plasmacytoid Dendritic Cells and Infected Cells Form an Interferogenic Synapse Required for Antiviral Responses.

Cell Host Microbe 2019 Apr 15. Epub 2019 Apr 15.

CIRI, Inserm, U1111, Université Claude Bernard Lyon 1, CNRS, UMR5308, École Normale Supérieure de Lyon, Univ Lyon, Lyon F-69007, France. Electronic address:

Type I interferon (IFN-I) is critical for antiviral defense, and plasmacytoid dendritic cells (pDCs) are a predominant source of IFN-I during virus infection. pDC-mediated antiviral responses are stimulated upon physical contact with infected cells, during which immunostimulatory viral RNA is transferred to pDCs, leading to IFN production via the nucleic acid sensor TLR7. Using dengue, hepatitis C, and Zika viruses, we demonstrate that the contact site of pDCs with infected cells is a specialized platform we term the interferogenic synapse, which enables viral RNA transfer and antiviral responses.

Hepatitis B e antigen induces the expansion of monocytic myeloid-derived suppressor cells to dampen T-cell function in chronic hepatitis B virus infection.

PLoS Pathog 2019 04 18;15(4):e1007690. Epub 2019 Apr 18.

Department of Infectious Diseases, Huashan Hospital, Fudan University, Shanghai, China.

Chronic hepatitis B virus (HBV) infection is associated with functionally impaired virus-specific T cell responses. Although the myeloid-derived suppressor cells (MDSCs) are known to play a critical role in impairing antiviral T cell responses, viral factors responsible for the expansion of MDSCs in chronic hepatitis B (CHB) remain obscure. In order to elucidate the mechanism of monocytic MDSCs (mMDSCs) expansion and T cell function suppression during persistent HBV infection, we analyzed the circulation frequency of mMDSCs in 164 CHB patients and 70 healthy donors, and found that the proportion of mMDSCs in HBeAg (+) CHB patients was significantly increased compared to that in HBeAg (-) patients, which positively correlated with the level of HBeAg.

Picornaviruses are small, icosahedral, nonenveloped, positive-sense, single-stranded RNA viruses that form one of the largest and most important viral families. Numerous Picornaviridae members pose serious health or agricultural threats, causing diseases such as poliomyelitis, hepatitis A, or foot-and-mouth disease. The antigenic characterization of picornavirus capsids plays an important role in understanding the mechanism of viral neutralization and the conformational changes associated with genome release, and it can point to regions which can be targeted by small-molecule compounds to be developed as antiviral inhibitors.

TIPE2 as a potential therapeutic target in chronic viral hepatitis.

Expert Opin Ther Targets 2019 Apr 17. Epub 2019 Apr 17.

a Department of Hepatology , Qilu Hospital of Shandong University , Jinan , China.

Introduction: Tumor necrosis factor-α-induced protein-8 like-2 (TIPE2) is a novel negative regulator of innate and adaptive immune responses by binding to caspase-8. The binding of TIPE2 and caspase-8 can inhibit the activity of activating protein-1(AP-1) and nuclear factor-κB (NF-κB), ultimately promoting Fas-induced apoptosis in immune cells. Therefore, TIPE2-caspase-8-NF-κB signaling might serve as a biomarker and a potential target for therapeutic intervention. Read More

Interleukin-35 modulates the balance between viral specific CD4CD25CD127 regulatory T cells and T helper 17 cells in chronic hepatitis B virus infection.

Virol J 2019 04 16;16(1):48. Epub 2019 Apr 16.

Department of Hepatopancreatobiliary Medicine, The Second Hospital, Jilin University, No. 218 Ziqiang Street, Nanguan District, Changchun, 130041, Jilin Province, China.

Background: Interleukin (IL)-35 regulates imbalance between regulatory T cells (Tregs) and T helper (Th) 17 cells, leading to an important modulator in autoimmune disorder, cancer, and infectious diseases. Our previous study revealed an immunosuppressive activity of IL-35 in chronic hepatitis B virus (HBV) infection. Thus, the aim of the current study was to investigate the role of regulatory function of IL-35 to viral specific Tregs/Th17 cells balance in chronic HBV infection. Read More

Basal expression of interferon regulatory factor 1 drives intrinsic hepatocyte resistance to multiple RNA viruses.

Nat Microbiol 2019 Apr 15. Epub 2019 Apr 15.

UNC Lineberger Comprehensive Cancer Center, Chapel Hill, NC, USA.

Current models of cell-intrinsic immunity to RNA viruses centre on virus-triggered inducible antiviral responses initiated by RIG-I-like receptors or Toll-like receptors that sense pathogen-associated molecular patterns, and signal downstream through interferon regulatory factors (IRFs), transcription factors that induce synthesis of type I and type III interferons. RNA viruses have evolved sophisticated strategies to disrupt these signalling pathways and evade elimination by cells, attesting to their importance. Less attention has been paid to how IRFs maintain basal levels of protection against viruses. Read More

Interpreting Viral Deep Sequencing Data with GLUE.

Viruses 2019 Apr 3;11(4). Epub 2019 Apr 3.

Peter Medawar Building for Pathogen Research, Nuffield Department of Medicine, University of Oxford, Oxford OX1 3SY, UK.

Using deep sequencing technologies such as Illumina's platform, it is possible to obtain reads from the viral RNA population revealing the viral genome diversity within a single host. A range of software tools and pipelines can transform raw deep sequencing reads into Sequence Alignment Mapping (SAM) files. We propose that interpretation tools should process these SAM files, directly translating individual reads to amino acids in order to extract statistics of interest such as the proportion of different amino acid residues at specific sites.

Hepatitis C Virus Genetic Variability, Human Immune Response, and Genome Polymorphisms: Which Is the Interplay?

Cells 2019 Apr 3;8(4). Epub 2019 Apr 3.

Department of Biology and Biotechnology, "C. Darwin" Sapienza University, 00100 Rome, Italy.

Hepatitis C virus (HCV) infection is the main cause of chronic hepatitis, affecting an estimated 150 million people worldwide. Initial exposure to HCV is most often followed by chronic hepatitis, with only a minority of individuals spontaneously clearing the virus. The induction of sustained and broadly directed HCV-specific CD4⁺ and CD8⁺ T cell responses, together with neutralizing antibodies (nAb), and specific genetic polymorphism have been associated with spontaneous resolution of the infection.

[Hepatitis C: From Individual Cure to Worldwide Elimination?]

Dtsch Med Wochenschr 2019 Apr 15;144(8):535-542. Epub 2019 Apr 15.

With the implementation of highly effective direct acting antivirals (DAAs), global control or even elimination of chronic hepatitis C virus (HCV) infection might have come into reach. In fact, DAA therapy leads to complete virus elimination, defined as sustained viral response (SVR), in the vast majority of patients. Moreover, in patients without cirrhosis, the risk of developing HCC after DAA therapy is significantly reduced. Read More

[Current and Future Therapy of Hepatitis B and D].

Authors:
Frank Tacke

Dtsch Med Wochenschr 2019 Apr 15;144(8):528-534. Epub 2019 Apr 15.

With approximately 240 million chronically infected people, hepatitis B virus (HBV) infection is a leading cause of cirrhosis and hepatocellular carcinoma in the world. Chronic HBV infection should be treated with antivirals, if either liver cirrhosis with detectable HBV DNA or relevant viral load (HBV DNA > 2000 IU/ml) and signs of liver damage (transaminase elevation, fibrosis, risk of liver cancer or similar) are present. The current standard therapy is a long-term treatment with nucleoside or nucleotide analogues such as entecavir, tenofovir disoproxil fumarate or tenofovir alafenamide, while in selected cases interferon treatment (for 48 weeks) may be useful.

Dtsch Med Wochenschr 2019 Apr 15;144(8):520-527. Epub 2019 Apr 15.

Chronic viral hepatitis can remain unrecognized but may nevertheless lead to liver cirrhosis and hepatocellular carcinoma. Thus, patients with elevated liver enzymes as well as risk groups need to be screened and treated for viral hepatitis. These groups include, in particular, migrants from countries with high HBV or HCV prevalence, persons with previous or current intravenous drug use, and homosexual men. Read More
