Spontaneous and Engineered Compensatory HSV Mutants that Counteract the Host Antiviral PKR Response
A virulent recombinant HSV lacking the diploid γ(1)34.5 gene (Δγ(1)34.5) have been investigated over the last two decades both for anti-tumor therapy and as vaccine vectors. The first generation vectors, while safe, are incapable of sustained replication in the majority of treated patients. An interferon inducible host antiviral kinase, protein kinase R (PKR), limits late viral protein synthesi...
متن کاملSuppression of proinflammatory cytokine expression by herpes simplex virus type 1.
Viral immune evasion strategies are important for establishment and maintenance of infections. Many viruses are in possession of mechanisms to counteract the antiviral response raised by the infected host. Here we show that a herpes simplex virus type 1 (HSV-1) mutant lacking functional viral protein 16 (VP16)-a tegument protein promoting viral gene expression-induced significantly higher level...
متن کاملSpecific inhibition of the PKR-mediated antiviral response by the murine cytomegalovirus proteins m142 and m143.
Double-stranded RNA (dsRNA) produced during viral infection activates several cellular antiviral responses. Among the best characterized is the shutoff of protein synthesis mediated by the dsRNA-dependent protein kinase (PKR) and the oligoadenylate synthetase (OAS)/RNase L system. As viral replication depends on protein synthesis, many viruses have evolved mechanisms for counteracting the PKR a...
متن کاملCompensatory networks to counteract the effects of ageing on language.
BACKGROUND Word-retrieval difficulties are a common consequence of healthy ageing and are associated with a reduction in asymmetrical recruitment of the dorsolateral prefrontal cortex (DLPFC), although the significance of this reduction has not yet been clarified. Using repetitive transcranial magnetic stimulation (rTMS) it has been demonstrated that an asymmetrical involvement of the DLPFC dur...
متن کاملActivation of the Antiviral Kinase PKR and Viral Countermeasures
The interferon-induced double-stranded (ds)RNA-dependent protein kinase (PKR) limits viral replication by an eIF2α-mediated block of translation. Although many negative-strand RNA viruses activate PKR, the responsible RNAs have long remained elusive, as dsRNA, the canonical activator of PKR, has not been detected in cells infected with such viruses. In this review we focus on the activating RNA...
