Chikungunya virus shuts down infected cells

By Wageningen University

Jelke Fros, a PhD student of the Laboratory of Virology in Wageningen, has discovered that the viral protein nsP2 blocks these processes by shutting down cellular RNA and protein production. This finding is important to explain the clinical symptoms of this disease and suggests that nsP2 can be an important target for the design of antiviral therapies. The results have been published in the Journal of General Virology.

Chikungunya virus – a new Pirate of the Caribbean

A large-scale chikungunya virus epidemic is ongoing in the Caribbean since December 2013. The virus is transmitted to humans via the bite of an infected mosquito. Human infection leads to high fever, rash and excruciating joint pains that may last for several months or years. There is no current vaccine or treatment for this debilitating disease.

Vaccine

Wageningen University previously developed a chikungunya virus-like particle (VLP) vaccine that protects animals from virus infection and associated disease symptoms. After several successful vaccination studies in mice, the efficacy of the prototype vaccine is currently being tested in non-human primates, in a collaboration with Top Institute Pharma and the Erasmus Medical Center. After completion of these important preclinical studies, the VLP vaccine may be further developed to enter clinical trials in humans.
