Multi-omics analysis of SFTS virus infection in Rhipicephalus microplus cells reveals antiviral tick factors - Nature Communications

OMG! I can finally share my joy to see my SFTSV work published in @natcomms.nature.com! This adventure started by the award of my MSCA grant and my move to the Kohl and @brennanlab.bsky.social at @cvrinfo.bsky.social. Let's chat about how we discovered novel tick anti-viral effectors!

By integrating our omics layers, we generated a comprehensive snapshot of SFTSV infection. However, to identify factors crucial for SFTSV, biological validation was necessary. We performed knockdown of selected effectors in tick cells and tested their roles in SFTSV replication and infectivity.

Finally we finalized our omics characterization by looking at the interactors of SFTSV N protein during an active infection. N interactors were mostly related to stress, or RNA regulation pathways. We identified interactors conserved in human, and other associated with immune response to bunyavirus.

We identified interactors conserved in human, and other associated with immune response to bunyavirus.
To understand our tick cell infection we focused on immune related pathways. We were able to map innate immune pathways (Jak-STAT, Toll, Imd). Interestingly little regulation was observed. Regulation was more important for stress-associated pathways suggesting a role in viral regulation.

Using this novel knowledge we studied the impact of SFTSV infection dynamics on tick cells. While the infection is asymptomatic in cells, we observed large change at 3 and 6 days post-infection. With little conservation of those changes overtime, suggesting large changes in infected cells.
