The Biological Characteristics and Mouse Model of Lassa Virus From the First Imported Case in China

MedComm, Volume 6, Issue 8, August 2025.
This is the first case of Lassa fever being introduced to China. A strain of the Lineage IV LASV was successfully isolated, and genomic and mutation analysis were conducted. Infection models were constructed using BALB/c, C57BL/6, and AG129 mice, which were successfully established.

Visualization of Double-Stranded RNA Colocalizing With Pattern Recognition Receptors in Arenavirus Infected Cells

Frontiers in Cellular and Infection Microbiology, 2018
An important step in the initiation of the innate immune response to virus infection is the recognition of non-self, viral RNA, including double-stranded RNA (dsRNA), by cytoplasmic pattern recognition receptors (PRRs).

An Antibody Recognizing the Apical Domain of Human Transferrin Receptor 1 Efficiently Inhibits the Entry of All New World Hemorrhagic Fever Arenaviruses [PDF]

Journal of Virology, 2012
ABSTRACT Five New World (NW) arenaviruses cause human hemorrhagic fevers. Four of these arenaviruses are known to enter cells by binding human transferrin receptor 1 (hTfR1). Here we show that the fifth arenavirus, Chapare virus, similarly uses hTfR1.

Evaluating the Potential Adverse Effects of Favipiravir on Biochemical, Histopathological, and Spermatological Parameters in Male Rats' Testicular Tissue

Journal of Biochemical and Molecular Toxicology, Volume 39, Issue 6, June 2025.
ABSTRACT Favipiravir is a selective RNA polymerase inhibitor and a broad‐spectrum antiviral drug. Favipiravir reduces cell proliferation by inhibiting RNA transcription, particularly in rapidly proliferating cells such as spermatogonia. The aim of this study was to investigate the effects and mechanism of action of favipiravir (T‐705) on sperm quality ...

Comprehensive Panel of Real-Time TaqMan™ Polymerase Chain Reaction Assays for Detection and Absolute Quantification of Filoviruses, Arenaviruses, and New World Hantaviruses [PDF]

The American Society of Tropical Medicine and Hygiene, 2010
Viral hemorrhagic fever is caused by a diverse group of single-stranded, negative-sense or positive-sense RNA viruses belonging to the families Filoviridae (Ebola and Marburg), Arenaviridae (Lassa, Junin, Machupo, Sabia, and Guanarito), and Bunyaviridae (hantavirus). Disease characteristics in these families mark each with the potential to be used as a

Therapeutic options for human papillomavirus‐positive tonsil and base of tongue cancer

Journal of Internal Medicine, Volume 297, Issue 6, Page 608-629, June 2025.
Abstract The incidences of human papillomavirus‐positive (HPV+) tonsillar and base tongue squamous cell carcinomas (TSCC and BOTSCC) have increased in recent decades. Notably, HPV+ TSCC and BOTSCC have a significantly better prognosis than their HPV‐negative counterparts when treated with current surgical options, radiotherapy, or intensified ...

An attenuated Machupo virus with a disrupted L-segment intergenic region protects guinea pigs against lethal Guanarito virus infection

Scientific Reports, 2017
Machupo virus (MACV) is a New World (NW) arenavirus and causative agent of Bolivian hemorrhagic fever (HF). Here, we identified a variant of MACV strain Carvallo termed Car91 that was attenuated in guinea pigs.
