Silver Nanoparticle‐Mediated Antiviral Efficacy against Enveloped Viruses: A Comprehensive Review

open access: yesGlobal Challenges, Volume 9, Issue 5, May 2025.
Silver nanoparticles (AgNPs) exhibit broad‐spectrum antiviral activity by targeting key viral structures and processes. They disrupt viral envelopes, compromising integrity, and bind to nucleocapsids, impairing viral replication. AgNPs also inhibit glycoprotein interactions, preventing viral attachment and entry into host cells.

Review of Mammarenavirus Biology and Replication

open access: yesFrontiers in Microbiology, 2018
The family Arenaviridae is divided into three genera: Mammarenavirus, Reptarenavirus, and Hartmanivirus. The Mammarenaviruses contain viruses responsible for causing human hemorrhagic fever diseases including New World viruses Junin, Machupo, Guanarito ...

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 Lassa Virus Stable Signal Peptide Undergoes a Conformational Change to Aid Viral Fusion

open access: yesChemistry – A European Journal, Volume 31, Issue 18, March 25, 2025.
The unique stable signal peptide (SSP) of the Lassa virus glycoprotein complex undergoes a conformational change during pH‐dependent viral fusion. This revels a potential mechanism by which the enigmatic SSP influences the fusion process through interactions it makes with the fusion protein, glycoprotein 2 (GP2).

Two Birds With One Stone: RNA Virus Strategies to Manipulate G3BP1 and Other Stress Granule Components

open access: yesWIREs RNA, Volume 16, Issue 2, March/April 2025.
Stress granules emerging during viral infection can play both pro‐ and antiviral roles. RNA viruses use various strategies to antagonize their formation, including the degradation, inhibition, or sequestration of G3BP1, a key stress granule protein. However, biochemical and structural insights into these mechanisms have been reported for only a handful

Junin Virus Triggers Macrophage Activation and Modulates Polarization According to Viral Strain Pathogenicity

open access: yesFrontiers in Immunology, 2019
The New World arenavirus Junin (JUNV) is the etiological agent of Argentine hemorrhagic fever (AHF). Previous studies of human macrophage infection by the Old-World arenaviruses Mopeia and Lassa showed that while the non-pathogenic Mopeia virus ...

CD164 is an endolysomal host factor for entry of Clade A New World Arenaviruses

open access: yes
Abstract Arenaviruses are divided into Old World (OW) and New World (NW) groups. OW arenaviruses enter cells through a pH-dependent receptor switch from a plasma-membrane factor to an endolysosomal receptor for subsequent membrane fusion, whereas clade B NW arenaviruses use transferrin receptor 1 without a secondary receptor.

Gene Expression Factors Associated with Rubella-Specific Humoral Immunity After a Third MMR Vaccine Dose

open access: yesViruses
Rubella is typically a mild viral illness, but it can lead to severe complications when contracted during pregnancy, such as pregnancy loss or developmental defects in the fetus (congenital rubella syndrome).
