Abstract
Hepatitis E is an underestimated disease, leading to estimated 20 million infections and up to 70,000 deaths annually. Infections are mostly asymptomatic, but can reach mortality rates up to 25% in pregnant women or become chronic in immunocompromised patients. Hepatitis E virus (HEV) infection have been associated with a range of extrahepatic manifestations, including a spectrum of neurological symptoms. Current therapy options are limited to non-specific antivirals like ribavirin, but recently, repurposed viral polymerase inhibitors like sofosbuvir and NITD008 were described to inhibit HEV replication. Here, we evaluated the efficacy of these drugs in various neuronal-derived cell lines to determine their potency outside the liver. Our findings indicate that both drugs, especially sofosbuvir, exhibited reduced efficacy in neuronal cells compared to hepatic cells. These results should be taken into account in the development of direct-acting antivirals for HEV and their potency at extrahepatic replication sites.
期刊介绍:
Antiviral Research is a journal that focuses on various aspects of controlling viral infections in both humans and animals. It is a platform for publishing research reports, short communications, review articles, and commentaries. The journal covers a wide range of topics including antiviral drugs, antibodies, and host-response modifiers. These topics encompass their synthesis, in vitro and in vivo testing, as well as mechanisms of action. Additionally, the journal also publishes studies on the development of new or improved vaccines against viral infections in humans. It delves into assessing the safety of drugs and vaccines, tracking the evolution of drug or vaccine-resistant viruses, and developing effective countermeasures. Another area of interest includes the identification and validation of new drug targets. The journal further explores laboratory animal models of viral diseases, investigates the pathogenesis of viral diseases, and examines the mechanisms by which viruses avoid host immune responses.
