Seroprevalence of Chikungunya and O'nyong‐nyong Viruses in Senegal, West Africa

Journal of Medical Virology, Volume 97, Issue 3, March 2025.
ABSTRACT Arthritogenic alphaviruses such as chikungunya (CHIKV) and o'nyong‐nyong (ONNV) viruses have shown capacity to cause widespread epidemics, with recurrent and sporadic outbreaks occurring throughout sub‐Saharan Africa. We analyzed the seroprevalence for CHIKV and ONNV in 470 non‐febrile subjects from three regions in Senegal (Sindia, 2018 ...

Alphavirus nsP2: A Multifunctional Regulator of Viral Replication and Promising Target for Anti‐Alphavirus Therapies

Reviews in Medical Virology, Volume 35, Issue 2, March 2025.
ABSTRACT Alphaviruses are re‐emerging vector‐born pathogens that cause arthralgia or encephalitic diseases on a global scale. While a vaccine against chikungunya virus was recently approved, no vaccines currently exist for other alphaviruses, nor are there antiviral drugs for the treatment of alphavirus infections. Alphaviruses have positive‐strand RNA

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

WIREs 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
