Development of a new tacaribe arenavirus infection model and its use to explore antiviral activity of a novel aristeromycin analog.

PLoS ONE, 2010
BackgroundA growing number of arenaviruses can cause a devastating viral hemorrhagic fever (VHF) syndrome. They pose a public health threat as emerging viruses and because of their potential use as bioterror agents. All of the highly pathogenic New World

Plasmacytoid Dendritic Cells Exhibit High Transferrin Receptor Expression Without Iron Accumulation

European Journal of Immunology, Volume 56, Issue 6, June 2026.
• pDCs are defined by high surface TFRC expression and dynamic iron flux, distinguishing them from conventional dendritic cell subsets. • In the Iron proteome, pDC are enriched for mitochondrial heme and Fe–S proteins but have similar iron storage to cDC. • Iron chelation does not disrupt pDC type‐1 IFN production. ABSTRACT Plasmacytoid dendritic cells

Identification and characterization of potent small molecule inhibitor of hemorrhagic fever New World arenaviruses

Antiviral Research, 2006
Category A arenaviruses as defined by the National Institute of Allergy and Infectious Diseases (NIAID) are human pathogens that could be weaponized by bioterrorists. Many of these deadly viruses require biosafety level-4 (BSL-4) containment for all laboratory work, which limits traditional laboratory high-throughput screening (HTS) for identification ...

Identification, Characterization, and In Vitro Culture of Highly Divergent Arenaviruses from Boa Constrictors and Annulated Tree Boas: Candidate Etiological Agents for Snake Inclusion Body Disease

mBio, 2012
Inclusion body disease (IBD) is an infectious fatal disease of snakes typified by behavioral abnormalities, wasting, and secondary infections. At a histopathological level, the disease is identified by the presence of large eosinophilic cytoplasmic ...

Structural biology of ferritin nanocages

FEBS Letters, Volume 600, Issue 10, Page 1420-1443, May 2026.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Old World and Clade C New World Arenaviruses Mimic the Molecular Mechanism of Receptor Recognition Used by α-Dystroglycan's Host-Derived Ligands [PDF]

Journal of Virology, 2007
ABSTRACTα-Dystroglycan (DG) is an important cellular receptor for extracellular matrix (ECM) proteins and also serves as the receptor for Old World arenaviruses Lassa fever virus (LFV) and lymphocytic choriomeningitis virus (LCMV) and clade C New World arenaviruses.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

Advanced Functional Materials, Volume 36, Issue 26, 30 March 2026.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

A multivalent and cross-protective vaccine strategy against arenaviruses associated with human disease.

PLoS Pathogens, 2009
Arenaviruses are the causative pathogens of severe hemorrhagic fever and aseptic meningitis in humans, for which no licensed vaccines are currently available. Pathogen heterogeneity within the Arenaviridae family poses a significant challenge for vaccine

The Protein Kinase Receptor Modulates the Innate Immune Response against Tacaribe Virus

Viruses, 2021
The New World (NW) mammarenavirus group includes several zoonotic highly pathogenic viruses, such as Junin (JUNV) or Machupo (MACV). Contrary to the Old World mammarenavirus group, these viruses are not able to completely suppress the innate immune ...
