Role 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 کاملPseudorabies virus US3 protein kinase mediates actin stress fiber breakdown.
Disruption of specific components of the host cytoskeleton has been reported for several viruses and is thought to be beneficial for viral replication and spread. Our previous work demonstrated that infection of swine kidney (SK-6) cells with pseudorabies virus (PRV), a swine alphaherpesvirus, induced actin stress fiber breakdown. In the present study, using several PRV deletion mutants, we fou...
متن کاملThe pseudorabies virus US3 protein is a component of primary and of mature virions.
Herpesviruses acquire a primary envelope by budding of capsids at the inner leaflet of the nuclear membrane. They then traverse into the cytoplasm after fusion of the primary envelope with the outer leaflet of the nuclear membrane. In the alphaherpesvirus pseudorabies virus (PrV), the latter process is impaired when the US3 protein is absent. Acquisition of final tegument and envelope occurs in...
متن کاملPseudorabies Virus Infection Alters Neuronal Activity and Connectivity In Vitro
Alpha-herpesviruses, including human herpes simplex virus 1 & 2, varicella zoster virus and the swine pseudorabies virus (PRV), infect the peripheral nervous system of their hosts. Symptoms of infection often include itching, numbness, or pain indicative of altered neurological function. To determine if there is an in vitro electrophysiological correlate to these characteristic in vivo symptoms...
متن کاملHerpes simplex virus protein kinase US3 activates and functionally overlaps protein kinase A to block apoptosis.
Herpes simplex virus 1 encodes at least four genes whose functions include blocking apoptosis induced by exogenous agents (e.g., sorbitol, Fas ligand, and BAD protein) or replication-incompetent mutants (e.g., the d120 mutant lacking both copies of the alpha 4 gene). U(S)3, one of these four genes, encodes a serine-threonine kinase that has been demonstrated to block apoptosis induced by proapo...
