Pre-print: our description of RZ affiliate ZNFX1 is now online.

On binding viral RNA, ZNFX1 generates parallel Ub currents, coordinating Ub-dependent RNA silencing and aggregate resolution.

Huge effort from first authors Dan Squair and @eilidhrivers.bsky.social

ZNFX1 uses two-component ubiquitin circuitry to quarantine viral RNA
The detection of viral RNA inside cells triggers a diverse range of antiviral responses, including global translation inhibition, interferon secretion and RNA sequestration. Mutations in the gene ZNFX...

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

Thread: How Viruses Hijack Tick RNA Machinery 🧬🕷️

Post 1/5 🧵
We just published the first map of how viruses rewire tick cell RNA machinery! Led by Alexandra Wilson & Wael Kamel!

We Found 283 proteins that change RNA-binding during Uukuniemi virus infection.

📄 Our paper: doi.org/10.1371/jour...
Uukuniemi virus infection causes a pervasive remodelling of the RNA-binding proteome in tick cells
Author summary In host cells, RNA-binding proteins play essential roles in the life cycle of many viruses by influencing how viral RNA is processed, translated, replicated and assembled into virions. ...

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!
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 tic...
