Animal Models of Pathogenic New World Arenaviruses

Microorganisms
Since the emergence of Junín virus in 1953, pathogenic New World arenaviruses have remained a public health concern. These viruses, which also include Machupo virus, Guanarito virus, Sabiá virus, and Chapare virus, cause acute viral hemorrhagic fever and

Antibodies to the Glycoprotein GP2 Subunit Cross-React between Old and New World Arenaviruses

mSphere, 2018
Arenaviruses pose a major public health threat and cause numerous infections in humans each year. Although most viruses belonging to this family do not cause disease in humans, some arenaviruses, such as Lassa virus and Machupo virus, are the etiological

Vaccine-elicited receptor-binding site antibodies neutralize two New World hemorrhagic fever arenaviruses [PDF]

Nature Communications, 2018
The five known New World hemorrhagic fever arenaviruses use the same entry receptor, but their viral glycoproteins are markedly different. Here, the authors isolate monoclonal antibodies from a Junin virus vaccinated person that cross-neutralize Machupo ...

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

PLoS 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 ...

Host-species transferrin receptor 1 orthologs are cellular receptors for nonpathogenic new world clade B arenaviruses.

PLoS Pathogens, 2009
The ability of a New World (NW) clade B arenavirus to enter cells using human transferrin receptor 1 (TfR1) strictly correlates with its ability to cause hemorrhagic fever.

Contrasting Modes of New World Arenavirus Neutralization by Immunization-Elicited Monoclonal Antibodies

mBio, 2022
Transmission of the New World hemorrhagic fever arenaviruses Junín virus (JUNV) and Machupo virus (MACV) to humans is facilitated, in part, by the interaction between the arenavirus GP1 glycoprotein and the human transferrin receptor 1 (hTfR1).

Genetic detection and characterization of Lujo virus, a new hemorrhagic fever-associated arenavirus from southern Africa. [PDF]

PLoS Pathogens, 2009
Lujo virus (LUJV), a new member of the family Arenaviridae and the first hemorrhagic fever-associated arenavirus from the Old World discovered in three decades, was isolated in South Africa during an outbreak of human disease characterized by nosocomial ...

Receptor determinants of zoonotic transmission of New World hemorrhagic fever arenaviruses [PDF]

Proceedings of the National Academy of Sciences, 2008
Transferrin receptor 1 (TfR1) is a cellular receptor for the New World hemorrhagic fever arenaviruses Machupo (MACV), Junín (JUNV), and Guanarito (GTOV). Each of these viruses is specifically adapted to a distinct rodent host species, but all cause human disease.

Different Mechanisms of Cell Entry by Human-Pathogenic Old World and New World Arenaviruses [PDF]

Journal of Virology, 2008
ABSTRACT The Old World arenavirus Lassa virus (LASV) is the causative agent of severe viral hemorrhagic fever (VHF) in humans and is the most prevalent human pathogen among arenaviruses. The present study investigated the largely unknown mechanisms of cell entry of LASV, a process know to be mediated solely by the virus envelope glycoprotein (
