Hepatitis C compromises the quality of life of more than 350 million individuals worldwide. Over the last decade, therapeutic regimens for treating hepatitis C virus (HCV) infections have undergone rapid advancements. Initially, structure-based drug design was used to develop molecules that inhibit viral enzymes. Subsequently, establishment of cell-based replicon systems enabled investigations into various stages of HCV life cycle including its entry, replication, translation, and assembly, as well as role of host proteins. Collectively, these approaches have facilitated identification of important molecules that are deemed essential for HCV life cycle. The expanded set of putative virus and host-encoded targets has brought us one step closer to developing robust strategies for efficacious, pangenotypic, and well-tolerated medicines against HCV. Herein, we provide an overview of the development of various classes of virus and host-directed therapies that are currently in use along with others that are undergoing clinical evaluation.

Introduction: Bovine viral diarrhea virus (BVDV), a positive-sense single-stranded RNA virus, causes significant economic losses in the cattle industry. Current diagnostic methods for BVDV exhibit variable sensitivity and specificity, underscoring the need for more rapid and accurate detection approaches. Here, we developed a novel competitive ELISA (cELISA) to detect antibodies against the BVDV E2 protein.

Background & Aims: Hepatitis E virus (HEV) constitutes a substantial public health burden with ∼20 million human infections annually, including 3.3 million symptomatic cases. Appropriate treatment options for, in particular, immunocompromised patients with HEV infection and pregnant women are lacking, underscoring the urgent need for potent and safe antiviral drugs.

Introduction: Pharmacotherapy against hepatitis C virus (HCV) infection has tremendously improved since the advent of interferon (IFN)-free direct-acting antivirals (DAAs). Additionally, fixed-dose pangenotypic DAAs, which are safe, potent, easy for use, and can cover a wide spectrum of patients, have been recommended by professional guidelines for DAA-naïve and DAA-experienced patients with HCV.
Areas Covered: We review the pharmacokinetics, pharmacodynamics, and potential drug-drug interactions (DDIs) of fixed-dose pangenotypic DAA regimens, including glecaprevir/pibrentasvir (GLE/PIB), sofosbuvir/velpatasvir (SOF/VEL), and sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX).

Background And Aims: Data on the prevalence and characteristics of so-called rare HCV genotypes (GTs) in larger cohorts is limited. This study investigates the frequency of rare GT and resistance-associated substitutions and the efficacy of retreatment in a European cohort.
Methods: A total of 129 patients with rare GT1-6 were included from the European resistance database.

This study aimed to develop a pan-genotypic and multifunctional small interfering RNA (siRNA) against hepatitis B virus (HBV) with an efficient delivery system for treating chronic hepatitis B (CHB), and explore combined RNA interference (RNAi) and immune modulatory modalities for better viral control. Twenty synthetic siRNAs targeting consensus motifs distributed across the whole HBV genome were designed and evaluated. The lipid nanoparticle (LNP) formulation was optimized by adopting HO-PEG-DMG lipid and modifying the molar ratio of traditional polyethylene glycol (PEG) lipid in LNP prescriptions.
