The pseudorabies virus VP22 homologue (UL49) is dispensable for virus growth in vitro and has no effect on virulence and neuronal spread in rodents.
The tegument of herpesvirus virions is a distinctive structure whose assembly and function are not well understood. The herpes simplex virus type 1 VP22 tegument protein encoded by the UL49 gene is conserved among the alphaherpesviruses. Using cell biology and viral genetics, we provide an initial characterization of the pseudorabies virus (PRV) VP22 homologue. We identified three isoforms of V...
متن کاملRole of pseudorabies virus Us3 protein kinase during neuronal infection.
The pseudorabies virus (PRV) Us3 gene is conserved among the alphaherpesviruses and encodes a serine/threonine protein kinase that is not required for growth in standard cell lines. In this report, we used a compartmented culture system to investigate the role of PRV Us3 in viral replication in neurons, in spread from neurons to PK15 cells, and in axon-mediated spread of infection. We also exam...
متن کاملIntercellular Trafficking of VP22, a Herpes Simplex Virus Type 1 Tegument Protein
The herpes simplex virus type 1 (HSV-1) tegument protein, VP22 has been reported to have the property of intercellular transport. The previous studies have shown that following expression of a fusion protein containing VP22 it spreads to every cell in a monolayer and concentrates in the nucleus. In spite of these reports, some studies have shown that VP22 trafficking and its nucleus accumulatio...
متن کاملActin is a component of the compensation mechanism in pseudorabies virus virions lacking the major tegument protein VP22.
Despite being a major component of the pseudorabies virus tegument, VP22 is not required for PRV replication, virulence, or neuroinvasion (T. del Rio, H. C. Werner, and L. W. Enquist, J. Virol. 76:774-782, 2002). In the absence of VP22, tegument assembly compensates in a limited fashion with increased incorporation of cellular actin. Infection of epithelial cell lines expressing fluorescent act...
متن کاملEffects of Sodium Valproate on the Replication of Herpes Simplex Virus Type 1: An in Vitro Study
Background: Sodium valproate, an anticonvulsant drug, is reported to stimulate Human Immunodeficiency Virus type 1 and Human cytomegalovirus replication. Since epileptic patients undergoing sodium valproate therapy may suffer from various virus infections, the effect of this drug on replication of viruses especially those affecting neuronal tissues such as Herpes simplex virus type 1 is worthy ...
