The N-terminal domain of the arenavirus L protein is an RNA endonuclease essential in mRNA transcription.

open access: yesPLoS Pathogens, 2010
Arenaviridae synthesize viral mRNAs using short capped primers presumably acquired from cellular transcripts by a 'cap-snatching' mechanism. Here, we report the crystal structure and functional characterization of the N-terminal 196 residues (NL1) of the

Missed Opportunities for Timely Diagnosis and Effective Therapeutic Management of Prolonged Fever: A Case Study of Confirmed Lassa Fever in N’Zérékoré, Guinea, 2022 [PDF]

open access: yesCase Reports in Infectious Diseases
Background Lassa fever is a potentially fatal viral hemorrhagic disease caused by a ribonucleic acid (RNA) virus of the Arenaviridae family, endemic in West Africa. It is highly virulent and contagious in several countries, with a nonspecific clinical presentation that poses a major public health challenge.

Biodistribution and toxicology evaluation of a recombinant measles Schwarz‐based Lassa vaccine in cynomolgus macaques

open access: yesJournal of Applied Toxicology, Volume 43, Issue 5, Page 719-733, May 2023., 2023
Abstract MV‐LASV is an investigational measles Schwarz‐based vaccine for the prevention of Lassa fever. A repeated‐dose toxicity study in cynomolgus macaques was performed to assess the biodistribution and local and systemic toxicological effects. Monkeys received three immunizations of MV‐LASV or saline intramuscularly with a 2‐week interval.

Genetic Evidence for a Tacaribe Serocomplex Virus, Mexico

open access: yesEmerging Infectious Diseases, 2010
We isolated arenavirus RNA from white-toothed woodrats (Neotoma leucodon) captured in a region of Mexico in which woodrats are food for humans. Analyses of nucleotide and amino acid sequence data indicated that the woodrats were infected with a novel ...
