Researchers identify a protein essential for Chikungunya virus replication

By 26th September 2019 No Comments

Chikungunya is an infectious disease caused by a mosquito-borne virus transmitted to humans. First detected in Africa, the virus has caused the recent epidemics in the Americas, Asia and the Indian Ocean – particularly the Reunion Island. Chikungunya is characterized by high fever and intense joint and muscle pain that can last for several months. Researchers still do not understand the mechanisms by which the virus infects human cells, but a team by Ali Amara in collaboration with Marc Lecuit from Inserm, the Institut Pasteur, CNRS and the Université de Paris have now identified a protein that plays a crucial role in virus replication within its target cells. This research, published in Nature, could lead to the development of new therapies in the fight against chikungunya.
