Dendritic cell-derived exosomes elicit tumor regression in autochthonous hepatocellular carcinoma mouse models

Dendritic cell-derived exosomes elicit tumor regression in autochthonous hepatocellular carcinoma mouse models | Hepatitis C New Drugs Review | Scoop.it
Dendritic cell (DC)-derived exosomes (DEXs) form a new class of vaccines for cancer immunotherapy. However, their potency in hepatocellular carcinoma (HCC) remains unknown. Here, we investigated exosomes from HCC antigen-expressing DCs in three different HCC mouse models and proved their feasibility and capability of treating HCC, and thus provide a cell-free vaccine for HCC immunotherapy.

Hepatitis C Virus-Induced Autophagy and Host Innate Immune Response

Hepatitis C Virus-Induced Autophagy and Host Innate Immune Response | Hepatitis C New Drugs Review | Scoop.it
Autophagy is a catabolic process that is important for maintaining cellular homeostasis. This pathway in hepatocytes is stimulated and controlled by the hepatitis C virus (HCV)—upon infection—to promote its own replication. HCV induces autophagy indirectly and directly through different mechanisms and temporally controls the autophagic flux. This enables the virus to maximize its replication and attenuate the innate immune responses that it activates. In this review, we discuss the relationship between HCV and autophagy, and the crosstalk between HCV-induced autophagy and host innate immune responses.

Shortening the duration of therapy for chronic hepatitis C infection

Shortening the duration of therapy for chronic hepatitis C infection | Hepatitis C New Drugs Review | Scoop.it
Combination direct-acting antiviral therapy of 8–24 weeks is highly effective for
the treatment of chronic hepatitis C infection. However, shortening the treatment
duration to less than 8 weeks could potentially reduce overall treatment costs and
improve adherence. Here we explore the arguments for and against the development of
short-duration regimens and existing data on treatment for 6 weeks or less among patients
with chronic hepatitis C virus genotype 1 infection. Additionally, we identify potential
predictors of response to short-course combination therapies with direct-acting antiviral
drugs that might be explored in future clinical trials.

Isolation and functional characterization of hepatitis B virus-specific T-cell receptors as new tools for experimental and clinical use

Isolation and functional characterization of hepatitis B virus-specific T-cell receptors as new tools for experimental and clinical use | Hepatitis C New Drugs Review | Scoop.it
T-cell therapy of chronic hepatitis B is a novel approach to restore antiviral T-cell immunity and cure the infection. We aimed at identifying T-cell receptors (TCR) with high functional avidity that have the potential to be used for adoptive T-cell therapy. To this end, we cloned HLA-A*02-restricted, hepatitis B virus (HBV)-specific T cells from patients with acute or resolved HBV infection. We isolated 11 envelope- or core-specific TCRs and evaluated them in comprehensive functional analyses. T cells were genetically modified by retroviral transduction to express HBV-specific TCRs. CD8+ as well as CD4+ T cells became effector T cells recognizing even picomolar concentrations of cognate peptide. TCR-transduced T cells were polyfunctional, secreting the cytokines interferon gamma, tumor necrosis factor alpha and interleukin-2, and effectively killed hepatoma cells replicating HBV. Notably, our collection of HBV-specific TCRs recognized peptides derived from HBV genotypes A, B, C and D presented on different HLA-A*02 subtypes common in areas with high HBV prevalence. When co-cultured with HBV-infected cells, TCR-transduced T cells rapidly reduced viral markers within two days. Our unique set of HBV-specific TCRs with different affinities represents an interesting tool for elucidating mechanisms of TCR-MHC interaction and dissecting specific anti-HBV mechanisms exerted by T cells. TCRs with high functional avidity might be suited to redirect T cells for adoptive T-cell therapy of chronic hepatitis B and HBV-induced hepatocellular carcinoma.

The Impact of the Hepatitis B Core Antibody Status on Recurrence in Patients with Non-B Non-C Hepatocellular Carcinoma after Curative Surgery

The Impact of the Hepatitis B Core Antibody Status on Recurrence in Patients with Non-B Non-C Hepatocellular Carcinoma after Curative Surgery | Hepatitis C New Drugs Review | Scoop.it
Abstract Background: The serum antibody to hepatitis B core antigen (HBcAb) is considered a risk factor of liver carcinogenesis. This study aimed to reveal whether HBcAb status is a prognostic factor after hepatectomy is performed for treating hepatocellular carcinoma (HCC). Methods: This retrospective study enrolled 272 patients who underwent hepatectomy as the initial treatment for HCC and who were followed up over 5 years after surgery. The types of HCC were classified into the following 3 types according to the hepatitis virus infection status and the patients without hepatitis virus infection non-B non-C HCC (NBNC-HCC) were further classified into 2 groups. Results: There is no novel finding as a result of the comparison made among hepatitis virus status. Of 90 patients (33.1%) with NBNC-HCC, 10 patients were excluded because the preoperative HBcAb status was not measured. There were 51 patients (63.8%) who were HBcAb-positive and 29 patients (36.2%) who were HBcAb-negative. In multivariate analysis, the presence of HBcAb-negative (hazard ratio 2.10, 95% CI 1.09-4.03, p = 0.026) remained as significant independent risk factors for recurrence in NBNC-HCC. Conclusions: This study shows that the HBcAb-positive is rather a favorable predictor for recurrence after curative resection in NBNC-HCC.

How far industry is from assembling a functional cure in HBV

How far industry is from assembling a functional cure in HBV | Hepatitis C New Drugs Review | Scoop.it
Early results for HBV monotherapies are pointing the way toward combinations that could deliver a functional cure. What remains unknown is how many components, and which ones, will prove necessary to eliminate remnants of the virus that persist on standard of care.Data on combinations that add a single MOA to standard of care will begin to read out over the next 18 months. More complex combinations, including cocktails combining novel mechanisms, are a few years away.

Our results show that 99% of patients treated with once-daily glecaprevir plus pibrentasvir
achieved a sustained virological response at 12 weeks. Furthermore, this drug regimen
had a favourable safety profile in previously treated or untreated patients with chronic
HCV genotype 1, 2, 4, 5, or 6 infection and compensated cirrhosis. These findings
could help simplify treatment algorithms and reduce treatment burden.

Hepatitis B and hepatitis C in southeast and southern Asia: challenges for governments

Hepatitis B and hepatitis C in southeast and southern Asia: challenges for governments | Hepatitis C New Drugs Review | Scoop.it
In 2015, the Coalition to Eradicate Viral Hepatitis in Asia Pacific gathered leading
hepatitis experts from Bangladesh, India, Indonesia, Malaysia, Pakistan, the Philippines,
and Thailand to discuss common challenges to the burden posed by hepatitis B virus
(HBV) and hepatitis C virus (HCV), to learn from each other's experience, and identify
sustainable approaches. In this report, we summarise these discussions. Countries
differ in their policy responses to HBV and HCV; however, substantial systemic, cultural,
and financial barriers to achievement of elimination of these infections persist in
all countries.

Cocrystal Pharma Hepatitis C picomolar inhibitor of NS5A

Cocrystal Pharma Hepatitis C picomolar inhibitor of NS5A | Hepatitis C New Drugs Review | Scoop.it
Developing a series of compounds that are potent non-nucleoside and nucleoside inhibitors of hepatitis C NS5B RNA dependent RNA polymerase, a replication enzyme that is essential to viral replication and is highly conserved between all hepatitis C genotypes. Therefore, inhibitors of this enzyme are likely to have multi- or pan-genotypic activity.

We are also developing compounds that inhibit hepatitis C NS5A and NS5B, two enzymes that are essential for viral replication. Cocrystal Pharma has identified a picomolar inhibitor of NS5A, another essential viral replication protein. Inhibitors of NS5A, in combination with nucleosides, have demonstrated excellent efficacy in treatment for hepatitis C in comparison with standard care. 

 Our compounds that target NS5B hepatitis C polymerase, NS5A and will be developed as a combination treatment. Such a combination treatment might have higher antiviral activity or a higher barrier to viral resistance than either treatment alone.

Treatment with PTEN-Long protein inhibits hepatitis C virus replication - ScienceDirect

Treatment with PTEN-Long protein inhibits hepatitis C virus replication - ScienceDirect | Hepatitis C New Drugs Review | Scoop.it
Publication date: November 2017
Source:Virology, Volume 511
Author(s): Qi Wu, Zhubing Li, Qiang Liu
Hepatitis C virus (HCV) infection is a confirmed risk factor for hepatocellular carcinoma (HCC). Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) possesses tumor suppression function that is frequently defective in HCC tumors. PTEN-Long, a translation isoform of PTEN, functions in a cell non-autonomous manner. In this study, we demonstrated that intracellular overexpression of PTEN-Long inhibits HCV replication. More importantly, we showed that treatment with extracellular PTEN-Long protein inhibits HCV replication in a dose-dependent manner. Furthermore, we showed that PTEN-Long interacts with HCV core protein and this interaction is required for HCV replication inhibition by PTEN-Long. In summary, we demonstrated, for the first time, that PTEN-Long protein, an isoform of the canonical PTEN and in the form of extracellular protein treatment, inhibits HCV replication. Our study offers an opportunity for developing additional anti-HCV agents.
