Arenavirus News and Research

RSS

Arenaviruses are enveloped viruses (about 120 nm diameter) with a bi-segmented negative strand RNA genome. The typical image in electronic microscopy showing grainy ribosomal particles (“arena” in latin) inside the virions gave the name to this family of viruses.

CEPI and University of Oxford launch new project to initiate vaccine development against Junín virus

The Coalition for Epidemic Preparedness Innovations (CEPI) and the University of Oxford today announced the launch of a new project to initiate early development of prototype vaccines against the Junín virus, selected as an exemplar of the Arenavirus family which is responsible for multiple deadly hemorrhagic fevers with epidemic and pandemic potential.

Host cell transmembrane protein MARCH8 targets lysine residues to inhibit SARS-CoV-2 and other viruses

A new study deals with the inhibitory activity of a membrane protein that has broad-spectrum activity against multiple viruses, showing that this is due to its effect on cytoplasmic lysine residue incorporation into replicating virions.

Coronacept - A trap-and-destroy molecule against SARS-CoV-2

A new study published on the preprint server bioRxiv* in August 2020 reports a novel engineered molecule based on human and other mammalian orthologues of ACE2 fused with the Fc part of the antibody. This molecule interacts more tightly with the viral receptor-binding domain (RBD) to constitute a powerful immunoadhesin that targets the virus for destruction.

Vaccine for Lassa fever set to enter clinical testing in humans

There is currently no vaccine for the Lassa arenavirus, which causes Lassa fever. This hemorrhagic fever, endemic in West Africa, infects up to 300,000 people each year.

Harvard scientists uncover key mechanism that allows viruses to replicate

Viruses are masterful invaders. They cannibalize host cells by injecting their genetic material, often making thousands of copies of themselves in a single cell to ensure their replication and survival.

Researchers decipher key component behind rising epidemic of pathogens in West Africa

A research team from several institutions being led by the University of California San Diego has deciphered a key component behind a rising epidemic of pathogens that the World Health Organization (WHO) recently added to its list of critical emerging diseases.

Study: Antibodies against hemorrhagic fever disarm two viruses of same family

Hemorrhagic fever viruses, so named for their ability to induce massive, and at times fatal, internal bleeding, captured the world's attention during the Ebola outbreak of 2014-2016 in West Africa.

TSRI study reveals first-ever structure of Lassa virus protein

Before Ebola virus ever struck West Africa, locals were already on the lookout for a deadly pathogen: Lassa virus. With thousands dying from Lassa every year-;and the potential for the virus to cause even larger outbreaks- researchers are committed to designing a vaccine to stop it.

TSRI study reveals important traits in LCMV, Lassa virus

For the first time, scientists at The Scripps Research Institute (TSRI) have solved the structure of the biological machinery used by a common virus to recognize and attack human host cells.

Novel virus could be source of severe respiratory disease in ball pythons

Researchers have identified a novel virus that could be the source of a severe, sometimes fatal respiratory disease that has been observed in captive ball pythons since the 1990s. The work is published this week in mBio-, the online open-access journal of the American Society for Microbiology.

Ebola, Marburg and Lassa viruses must be designated as emerging diagnoses

The Ebola, Marburg and Lassa viruses are commonly referred to as emerging diseases, but leading scientists say these life-threatening viruses have been around for centuries.
