Highly Pathogenic New World Arenavirus Infection Activates the Pattern Recognition Receptor Protein Kinase R without Attenuating Virus Replication in Human Cells [PDF]

open access: yesJournal of Virology, 2017
ABSTRACT The arenavirus family consists of several highly pathogenic viruses, including the Old World (OW) arenavirus Lassa fever virus (LASV) and the New World (NW) Junin virus (JUNV) and Machupo virus (MACV). Host response to infection by these pathogenic arenaviruses is distinct in many aspects.

Novel Oliveros-like Clade C Mammarenaviruses from Rodents in Argentina, 1990–2020

open access: yesViruses
Following an Argentine Hemorrhagic Fever (AHF) outbreak in the early 1990s, a rodent survey for Junín virus, a New World Clade B arenavirus, in endemic areas of Argentina was conducted.

Involvement of Pro-Inflammatory Macrophages in Liver Pathology of Pirital Virus-Infected Syrian Hamsters

open access: yesViruses, 2018
New World arenaviruses cause fatal hemorrhagic disease in South America. Pirital virus (PIRV), a mammarenavirus hosted by Alston’s cotton rat (Sigmodon alstoni), causes a disease in Syrian golden hamsters (Mesocricetus auratus) (biosafety level-3 ...

The New World arenavirus Tacaribe virus induces caspase-dependent apoptosis in infected cells

open access: yesJournal of General Virology, 2016
The Arenaviridae is a diverse and growing family of viruses that already includes more than 25 distinct species. While some of these viruses have a significant impact on public health, others appear to be non-pathogenic. At present little is known about the host cell responses to infection with different arenaviruses, particularly those found in the ...

Potent inhibition of Junín virus infection by interferon in murine cells. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2014
The new world arenavirus Junín virus (JUNV) is the causative agent of Argentine hemorrhagic fever, a lethal human infectious disease. Adult laboratory mice are generally resistant to peripheral infection by JUNV.

Molecular organization of the New World arenavirus spike glycoprotein complex

open access: yesNature Microbiology
Abstract Of the multiple arenaviruses that cause haemorrhagic fevers in the Americas, all lack reliable therapeutic options, and only one has a vaccine. The arenavirus glycoprotein complex (GPC) binds cellular receptors and mediates pH-dependent fusion of viral and host cell membranes during entry.

Temporal changes in pathology and viral RNA distribution in guinea pigs following separate infection with two New World Arenaviruses.

open access: yesPLoS Neglected Tropical Diseases, 2023
Numerous arenaviruses have been identified throughout the Americas and a subset of these viruses cause viral hemorrhagic fever in humans. This study compared the pathology and viral RNA distribution in Hartley guinea pigs challenged with two human ...

An attenuated Machupo virus with a disrupted L-segment intergenic region protects guinea pigs against lethal Guanarito virus infection

open access: yesScientific Reports, 2017
Machupo virus (MACV) is a New World (NW) arenavirus and causative agent of Bolivian hemorrhagic fever (HF). Here, we identified a variant of MACV strain Carvallo termed Car91 that was attenuated in guinea pigs.

Tacaribe virus but not junin virus infection induces cytokine release from primary human monocytes and macrophages. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2011
The mechanisms underlying the development of disease during arenavirus infection are poorly understood. However, common to all hemorrhagic fever diseases is the involvement of macrophages as primary target cells, suggesting that the immune response in ...
