Infection of Mammals and Mosquitoes by Alphaviruses: Involvement of Cell Death

09 December 2020

Alphaviruses and cell death
Alphaviruses, such as the chikungunya virus, are emerging and re-emerging viruses that pose a global public health threat. They are transmitted by blood-feeding arthropods, mainly mosquitoes, to humans and animals. Although alphaviruses cause debilitating diseases in mammalian hosts, it appears that they have no pathological effect on the mosquito vector. Alphavirus/host interactions are increasingly studied at cellular and molecular levels. While it seems clear that apoptosis plays a key role in some human pathologies, the role of cell death in determining the outcome of infections in mosquitoes remains to be fully understood. Here, we review the current knowledge on alphavirus-induced regulated cell death in hosts and vectors and the possible role they play in determining tolerance or resistance of mosquitoes.

Dr Carine Maisse (team Alphaviruses Transmission and comparative pathology) and Lucie Cappuccio (PhD student) just published a review entitled  "Infection of Mammals and Mosquitoes by Alphaviruses: Involvement of Cell Death"
