I am advertising for a PhD position in my group. We'll be investigating how pathogenic RNA viruses replicate in the nucleus. The project will teach cryoEM/ET, virus culture, and in vitro assays.

If you're interested reach out and I'd be happy to have a chat.

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.

“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.”

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 🌍.

Multi-omics analysis of SFTS virus infection in Rhipicephalus microplus cells reveals antiviral tick factors - Nature Communications Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) is a deadly tick-borne virus and a growing global health threat. In this study, Petit et al. used a multi-omics approach on SFTSV-infected tick cells to study its impact and reveal host antiviral responses and key restriction factors.

Quality of scientific papers questioned as academics ‘overwhelmed’ by the millions published Widespread mockery of AI-generated rat with giant penis in one paper brings problem to public attention

“Volume is a bad driver,” [Sir Mark Walport] said. “The incentive should be quality, not quantity. It’s about re-engineering the system in a way that encourages good research from beginning to end.”

A reddish-brown tick crawls on light-colored fabric. Headline: Tick Bites Are No Joke. Here’s How to Prevent Them and Protect Yourself.

The mere thought of ticks makes our skin crawl. And the diseases they spread are only getting more common. Here are some simple tricks for preventing tick bites and techniques for removing them if they do bite. nyti.ms/4jsK6Km

Finally A BIG THANK YOU to all my co-authors, they made this long journey started in 2021 a bit smoother! Thanks to Scaturro lab, Kohl lab, @brennanlab.bsky.social, @quangu.bsky.social, and Dundee proteomics! And of course thanks to the Tick cell Biobank and Lesley for those tiny cells!

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.

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!

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!

Calling all virologists: my lab is hiring a tech for high containment work! Come work with our amazing team at 🇨🇦's National Pandemic Research Centre, using experimental, systems biology, & AI-driven approaches to study infection & pathogenesis of emerging viruses.

Trump freezes ‘gain of function’ pathogen research ― threatening all US virology, critics say An executive order suspends the use of federal funds for certain experiments on pathogens with pandemic potential. Critics say low-risk science could be affected too.

“This is what I was expecting — an executive order banning gain-of-function research but defined in such a way that it bans all virology research,” says @ggronvall.bsky.social.

Yup.
