West Nile virus (WNV), a neurotropic single-stranded flavivirus has been the leading cause of arboviral encephalitis worldwide. Up to 50% of WNV convalescent patients in the United States were reported to have long-term neurological sequelae. Neither antiviral drugs nor vaccines are available for humans. Animal models have been used to investigate WNV pathogenesis and host immune response in humans. In this review, we will discuss recent findings from studies in animal models of WNV infection, and provide new insights on WNV pathogenesis and WNV-induced host immunity in the central nervous system.
