title: Restricted virus protein translation in canine distemper virus inclusion body polioencephalitis.
abstract: In this study, inclusion body polioencephalitis, an uncommon form of canine distemper virus (CDV)-induced encephalitis, was investigated for viral protein and mRNA expression by immunohistochemistry (IH) and in situ hybridization and, in addition, infiltrating cells were characterized by IH. Lesions were predominantly found in the grey matter of the brain stem and the immune response, dominated by T cells, was associated with a strong MHC II upregulation. Abundant expression of all viral protein mRNAs and reduced or lacking protein translation, especially of the matrix protein were the most important findings, indicating that restricted virus infection in the grey matter might represent a mechanism for viral persistence in distemper polioencephalitis.
