Abstract

West Nile virus (WNV) can cause encephalitis or meningitis that affects brain tissue, which can also lead to permanent neurological damage that can be fatal. To our knowledge, no consistent double immunohistochemical staining of neurons, neuroglia cells, and WNV has yet been reported. To establish a method for performing double-label immunohistochemical detection of neurons, neuroglia cells and WNV, examining the pathological characteristics of WNV-infected neurons, neuroglia cells, and investigating distribution of WNV in monkey brain, paraffin-embedded monkey brain tissue were retrospectively studied by immunohistochemical staining of neurons, neuroglia cells and WNV. Antibodies against neuron-specific enolase (NSE), glial fibrillary acidic protein (GFAP) and WNV were used to develop the method of double-label immunohistochemical staining, which allowed independent assessment of neuron status and WNV distribution. A range of immunohistochemical WNV infection in monkey brain was observed in both neurons and neuroglia cells in terms of the thickness of lesion staining, and the WNV staining was slightly higher in neuroglia cells than in neurons. All these findings suggest that WNV invasion in the brain plays a crucial role in neurological damage by inducing central nervous system (CNS) cell dysfunction or cell death directly.
