Inhibition of human norovirus by a viral polymerase inhibitor in the B cell culture system and in the mouse model

Abstract

The recently developed human norovirus (HuNoV) B cell culture and mouse models hold promise for drug discovery and development but their suitability for antiviral studies has not been assessed. We demonstrate the inhibitory effect of the nucleoside analogue 2′-C-methylcytidine (2CMC) on HuNoV replication in the human B cell BJAB cell line and in Balb/c Rag/gamma chain-deficient (Rag-γc−/−) mice. These data suggest the applicability of both models for future study and development of antiviral drugs for the treatment of HuNoV infections.
