Summary: HCV testing and treatment dropped by more than 30% in April 2020 due to the COVID-19 pandemic, and although HCV testing increased again later in 2020, HCV treatment rates did not recover.

Summary: This study found that single-nucleotide polymorphism CXCL13_rs76084459 is significantly associated with response to PegIFNa therapy in patients with chronic hepatitis B. Furthermore, a polygenic score composed of 6 SNPs including CXCL13_rs76084459 has a better predictive value for PegIFNa treatment response.

Summary: RNA viruses produce dsRNA during viral genome replication, which triggers the production of interferon-beta and activates the immune response. The NS5B protein derived from hepatitis C virus (HCV) induces the dimerization of MDA5 and the production of dsRNA, leading to an innate immune response in human hepatocytes.

Summary: The World Health Organization's goal of eliminating Hepatitis C virus (HCV) by 2030 using direct-acting antiviral treatments has become less attainable post the 2020 pandemic of coronavirus disease 2019. Therefore, a more realistic approach of micro-elimination in population segments where targeted strategies of prevention and treatment are easily attained has been promoted in Europe. Active involvement of stakeholders and community participation are essential components for the success of a micro-elimination project tailored at the geographical level according to HCV epidemiology and individual country's income.

Summary: This study investigated the correlation between the expression levels of HSP90 isoforms and inflammatory response marker NLRP3 in different types of HCC patients, as well as the effect of celastrol in suppressing HCV translation and associated inflammatory response. The study found that the expression level of HSP90 beta isoform was correlated with that of NLRP3 in HCV positive HCC patients. Additionally, celastrol exhibited inhibitory effects on HCV translation and associated inflammation by specifically targeting HSP90 beta.

Summary: Following a study demonstrating the role of hepatitis C virus (HCV) in transmitting hepatitis D virus (HDV) in a liver-humanized mouse model, a large cohort of HCV-positive blood donors were screened for HDV markers. However, no evidence of HCV-assisted propagation of HDV in humans was found.

Summary: This study found that overexpression of BST2 can improve the anti-HBV effect of IFN-α treatment, and BST2_rs9576 is an effective indicator for predicting the therapy response of PegIFN alpha-treated patients with CHB. The PGS model has the potential to enhance the ability of PegIFN alpha therapy response.

Summary: The liver is an immunoprivileged organ with enhanced resistance to immune responses. This study shows that CD302 contributes to liver cell-intrinsic defense against HCV and might mediate broader antiviral defenses against additional hepatotropic viruses.

Summary: In this Review, the authors discuss quasi-enveloped virions, their entry and release from human host cells, and their impact on host immunity and pathogenesis. They focus on hepatitis A and E viruses, which were previously considered non-enveloped but are now known to be released as quasi-enveloped virions cloaked in host membranes. Despite lacking virally encoded proteins on their surface, these virions efficiently enter cells and replicate. The authors also describe the mechanisms by which specific peptide sequences in the capsids of these virions mediate their release from hepatocytes and the current understanding of their cell entry mechanism.

Summary: A new strategy has been developed to overcome the genetic diversity of the hepatitis C virus by eliciting broadly neutralizing antibodies. The strategy involves immunizing mice with variants from different clusters of the immunodominant hyper-variable region 1, resulting in sera that can neutralize diverse HCV variants. This approach offers a potential solution for antigenic variability in other highly mutable viruses.

Summary: In this study, a dual-therapeutic platform using engineered graphene oxide (GO) as a multi-functional co-delivery carrier was developed. It successfully delivered two therapeutic reagents as a single vehicle, targeting multiple organelles in cells. The combination therapy showed enhanced efficacy in suppressing tumor growth and had a two-fold therapeutic efficiency compared to single-drug treatment.

Summary: Significant progress has been made in the treatment of viral hepatitis, including curative therapies for hepatitis C and advancements in vaccination for hepatitis A, B, and E. There is currently no cure for hepatitis B, but targeted antiviral drugs show promise in eradicating the virus. High vaccination coverage and large-scale test-and-treat programs may ultimately eliminate viral hepatitis and reduce the burden on health systems.

Summary: Serum HBV pgRNA kinetics during treatment and around HBsAg loss show varied patterns, with most patients maintaining detectable levels of pgRNA even after achieving HBsAg loss. Baseline serum HBV pgRNA alone is insufficient for predicting the trajectory of HBV pgRNA. Further studies on HBV pgRNA kinetics around HBsAg loss would provide valuable insights for future applications of HBV pgRNA.

Summary: The study indicates that patients who can produce IFN-lambda 4, along with male gender, milder steatosis, and lower viral load, have higher levels of antibodies against HCV. This suggests that IFN-lambda 4 may be associated with Th2 immune skewing and could have clinical implications beyond HCV infection.

Summary: The absence of IFN-lambda 4 increases the likelihood of spontaneous resolution of acute HCV infections, especially for individuals who have been repeatedly exposed to HCV. ITPase genetic variants do not independently impact outcomes, but in males lacking IFN-lambda 4, reduced ITPase activity significantly improves the likelihood of virus clearance.

Summary: This study found that genetic variations within the CYBA gene, which affects the formation of reactive oxygen species (ROS), are associated with the severity and progression of multiple sclerosis (MS). Specifically, low-ROS alleles were linked to reduced MS severity and delayed onset of secondary progressive MS (SPMS). These findings suggest that targeting the NOX2 enzyme may be a potential therapeutic strategy to delay secondary progression in MS.

Summary: This study investigated the impact of repeated vaccination and hybrid immunity on antibody levels in immunosuppressed patients. The results showed that immunosuppressed patients achieved antibody levels comparable to controls after receiving three doses of the vaccine. Hybrid immunity resulted in approximately 10-fold higher antibody levels than vaccine-induced immunity alone in all study cohorts.
