Influence of pseudorabies virus proteins on neuroinvasion and neurovirulence in mice.

Influence of tegument proteins of pseudorabies virus on neuroinvasion and transneuronal spread in the nervous system of adult mice after intranasal inoculation.

Pseudorabies virus (PrV) is a neurotropic alphaherpesvirus that, after intranasal infection of adult mice, enters peripheral neurons and propagates to the central nervous system. In recent years we have analyzed the contribution of virus-encoded glycoproteins to neuroinvasion and transneuronal spread (reviewed in T. C. Mettenleiter, Virus Res. 92:197-206, 2003). We now extend our studies to ana...

Neuroinvasion and Lethality in Mice Two Modes of Pseudorabies Virus

Relevance of the interaction between alphaherpesvirus UL3.5 and UL48 proteins for virion maturation and neuroinvasion.

The UL3.5 and UL48 genes, which are conserved in most alphaherpesvirus genomes, are important for maturation of pseudorabies virus (PrV) particles in the cytoplasm of infected cells (W. Fuchs, B. G. Klupp, H. J. Rziha, and T. C. Mettenleiter, J. Virol. 70:3517-3527, 1996; W. Fuchs, H. Granzow, B. G. Klupp, M. Kopp and T. C. Mettenleiter, J. Virol. 76:6729-6742, 2002). In bovine herpesvirus 1 (B...

Disease duration determines canine distemper virus neurovirulence.

The Morbillivirus hemagglutinin (H) protein mediates attachment to the target cell. To evaluate its contribution to canine distemper virus neurovirulence, we exchanged the H proteins of the wild-type strains 5804P and A75 and assessed the pathogenesis of the chimeric viruses in ferrets. Both strains are lethal to ferrets; however, 5804P causes a 2-week disease without neurological signs, wherea...

Aujeszky's disease (pseudorabies) virus: the virus and molecular pathogenesis--state of the art, June 1999.

Considerable progress has been made during the last years in understanding the molecular basis of protein function in pseudorabies virus (PrV), the causative agent of Aujeszky's disease (AD). Major topics have been the identification and functional characterisation of viral envelope glycoproteins and cellular virus receptors, elucidation of viral proteins involved in neurovirulence and neuropat...
