Ebola Virus Infection of Dendritic Cells
Biography

Ebola virus (EBOV), a negative sense single stranded RNA virus of the Filoviridae family, is the pathogen behind episodic outbreaks of hemorrhagic fever. With mortality rates for infections often exceeding 50% and an outbreak currently underway in the DRC (As of June 2018), solidifying our understanding of Ebola virus pathogenesis is an urgent need. It is widely agreed that macrophages and dendritic cells, major players in the innate immune system, are the earliest cell types to sustain significant and persistent Ebola virus replication. Previous research in our lab has explored the impacts of macrophage polarization on infectability, but there is a dearth of research in the field with regard to dendritic cell infection. Multiple viruses, including SARS-CoV, measles, and Toscana virus, preferentially infect dendritic cells, harnessing their migratory capabilities to disseminate viral progeny throughout host tissue and lymphatics. The systemic nature of Ebola hemorrhagic fever suggests that EBOV may too employ this mechanism. My project seeks to address the underlying questions of this model, namely which DC populations are readily and productively infected and which receptor is used to initiate EBOV entry in these cell types.
