Six-Month Progress Reports

My SPARK project explores why bat-associated viruses, like Ebola, are harmless in bats but deadly in humans. I aim to uncover how these viruses form structures in infected cells, known as viral factories. Preliminary experiments in both human and bat cells suggest that these viral factories can trap cellular mRNAs and make it harder for the host’s immune system to fight infection. My ongoing analysis will help identify which mRNAs are trapped by the viral factories in human cells.

My next steps will be to validate these findings in bat cells and measure the impact of mRNA trapping a cell’s ability to produce antiviral proteins. Understanding how these viruses manipulate immune responses differently in bats and humans could lead to new strategies for boosting immunity and developing effective treatments for infectious diseases such as Ebola.

So far, my research has also supported the continued use of a cutting-edge spatial transcriptomics technique called MERFISH to investigate viral factories. I’m currently using MERFISH to map and count over a hundred cellular antiviral mRNAs in human cells carrying Ebola viral factories.

SPARKing Impact: Successful completion of my project will advance our knowledge of how bats resist Ebola virus infection and inform the design of effective therapeutics to protect against deadly viruses transmitted by bats.
