The human cytomegalovirus (HCMV) virion protein pUL83 (also termed pp65) inhibits the expression of interferon-inducible cellular genes. In this work we demonstrate that pUL83 is also important for efficient induction of transcription from the viral major immediate-early promoter. Infection with a mutant virus containing a premature translation termination(More)
Junín virus is the causative agent for Argentine hemorrhagic fever, and its natural host is the New World rodent Calomys musculinus. The virus is transmitted to humans by aerosolization, and it is believed that many of the clinical symptoms are caused by cytokines produced by sentinel cells of the immune system. Here we used the Junín virus vaccine strain(More)
Successful adaptive immunity to virus infection often depends on the initial innate response. Previously, we demonstrated that Junín virus, the etiological agent responsible for Argentine hemorrhagic fever (AHF), activates an early innate immune response via an interaction between the viral glycoprotein and Toll-like receptor 2 (TLR2). Here we show that(More)
New World hemorrhagic fever arenavirus infection results in 15 to 30% mortality in humans. We performed a high-throughput small interfering RNA screen with Junín virus glycoprotein-pseudotyped viruses to find potential host therapeutic targets. Voltage-gated calcium channel (VGCC) subunits, for which there are Food and Drug Administration (FDA)-approved(More)
UNLABELLED Virus entry into cells is a multistep process that often requires the subversion of subcellular machineries. A more complete understanding of these steps is necessary to develop new antiviral strategies. While studying the potential role of the actin network and one of its master regulators, the small GTPase Cdc42, during Junin virus (JUNV)(More)
