Structure and stabilization of the antigenic glycoprotein building blocks of the New World mammarenavirus spike complex [PDF]

mBio
The spillover of New World (NW) arenaviruses from rodent reservoirs into human populations poses a continued risk to human health. NW arenaviruses present a glycoprotein (GP) complex on the envelope surface of the virion, which orchestrates host cell ...

Lassa and Mopeia viruses produce different RIG-I-activating RNA in the absence of a functional viral exoribonuclease domain [PDF]

Journal of Virology
All viruses of the genus Mammarenavirus possess an exoribonuclease (ExoN) domain in their nucleoproteins (NP). Through this domain, the NP efficiently prevents the activation of the interferon (IFN) response, presumably by degrading double-stranded RNA ...

A hTfR1 Receptor-Specific VHH Antibody Neutralizes Pseudoviruses Expressing Glycoproteins from Junín and Machupo Viruses [PDF]

Viruses
The Junín virus (JUNV) is one of the New World arenaviruses that cause severe hemorrhagic fever. Human transferrin receptor 1 (hTfR1) has been identified as the main receptor for JUNV for virus entry into host cells.

Climate-driven changes in zoonotic risk of arenaviral hemorrhagic fevers in South America [PDF]

npj Viruses
Climate change is expected to significantly alter the ecological dynamics of zoonotic diseases, yet its long-term impact on rodent-borne hemorrhagic fevers in South America remains poorly understood.

Role of Src family kinases Fyn and Lyn in arenavirus infection [PDF]

Journal of Virology
Arenaviruses encompass a diverse group of infectious agents, some of which, like Lassa virus (LASV), pose significant threats to global public health due to their acute virulence, while others, such as lymphocytic choriomeningitis virus (LCMV), are less ...

Comparison of Vaccine Platforms for Machupo Virus [PDF]

Vaccines
Background/Objectives: Pathogenic mammarenaviruses cause severe hemorrhagic and neurologic disease in humans. Machupo virus (MACV), a New World (NW) mammarenavirus, causes Bolivian hemorrhagic fever in humans, and there are no approved vaccines. Methods:

Discovery and biological confirmation of a highly divergent Tacaribe virus in metatranscriptomic data from neotropical bats [PDF]

mSphere
First isolated from neotropical fruit bats in Trinidad in 1956, Tacaribe virus (TCRV) has rarely been detected since. We searched for New World arenavirus reads in roughly 5.7 million sequencing runs available on public databases using Serratus.

Special Issue “Arenaviruses 2020”

Viruses, 2021
Rodent-borne arenaviruses have been traditionally predominantly associated with certain muroid species from Mastomys/Praomys genera (African arenaviruses) or with species that belong to murid subfamily Cricetidae (New World arenaviruses) [...]
