Inflammation and cytopenia are commonly observed during Ebola virus (EBOV) infection; however, mechanisms responsible for EBOV-induced cell death remain obscure. While apoptosis and necrosis are already identified as mechanisms of cell death induced by the virus, our study demonstrates that THP-1 monocytes and SupT1 T cells exposed to EBOV undergo pyroptosis and necroptosis, respectively, through a direct contact with EBOV, and also mediate pyroptosis or necroptosis of uninfected bystander cells via indirect effects associated with secreted soluble factors. These results emphasize novel aspects of interactions between EBOV and immune cell populations and provide a better understanding of the immunopathogenesis of EBOV disease.
