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!

“As human-driven climate change makes winters shorter, ticks are spending less time hibernating and have more active months when they can hitch rides on animals and people. Sometimes the ticks carry themselves — and diseases — to new parts of the country.”
Ticks are migrating, but scant surveillance may leave doctors in the dark on patient treatment
Health departments struggle to adequately survey for ticks to warn doctors about new species and the diseases they carry.

Curious about tick virology? Read my latest piece in @uk.theconversation.com where I explain findings of my latest research article www.nature.com/articles/s41...

Hope it will helps people to understand the importance of studying tick and their pathogens #ScienceforAll #WomenInScience #Arbovirose

Only 2.5% of animal biomass is human.

Still, that fraction is reshaping the fate of the whole 🌍.

We created a team of AI agents to mirror my Stanford lab 🤖. Led by a PI agent, the AI scientists ran their own group meetings and discovered effective binders to new CoVID variants that we validated.

Our strategy successfully identified two novel antiviral effectors: DHX9 and UPF1, both RNA helicases. While these proteins are known to participate in RNA detection and degradation, their precise mechanism of action against SFTSV remains unclear... Stay tuned for the next chapter! 🔍 #TickVirology

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.

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.

Marine Petit @virotick.bsky.social · May 23
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.

Our first objective was to generate a better transcriptome and the first reference proteome for BME/CTVM6 tick cells. Following RNA and protein extraction, we performed proteomic informed by transcriptomic analysis. This approach brings insights into the molecular biology of our tick vector system.

Ticks are vector of many pathogens including hemorrhagic fever virus like SFTSV. Identified in 2009, SFTSV interaction with its tick vector remains understudied. To bypass limited understanding and tools available I used my system virology expertise to explore tick-virus interactions!
