Persistent interferon signaling causes sensory neuron plasticity and pain before and during arthritis - Nature Neuroscience Su et al. show that inflammatory arthritis pain stems from sustained interferon-driven MNK1/MNK2–elF4E signaling that sensitizes joint-innervating neurons. Blocking this pathway reverses pain, suggest...

BOOM! Fantastic new paper from Patrik Ernfors and his team: www.nature.com/articles/s41... Persistent interferon signaling causes sensory neuron plasticity and pain before and during arthritis

🌟Today @fg-pgc.bsky.social and @pgcgenetics.bsky.social are in Bengaluru, India, where we love to highlight Dr KALYANI BINDU's work and the dynamic #functionalgenomics scene 🧬🧠
She shows that many of the same biological mechanisms play a role in different #mentalhealth disorders ! One drug for all?

Pet peeve: when someone invites you to a meeting but instead of sending a calendar invitation, they just send a zoom link in an email.

If you want profs to actually show up for meetings-- send a calendar invitation!

A genome-wide analysis of the shared genetic risk architecture of complex neurological and psychiatric disorders Nature Neuroscience - Smeland et al. demonstrate greater genetic overlap between neurological and psychiatric disorders than previously recognized, along with diverse neurobiological associations....

Excited to share our cross-disorder GWAS analysis of neurological and psychiatric disorders (~1 M cases), now out in @natneuro.nature.com! We show more extensive genetic pleiotropy than previously recognized, supporting a more unified view of these disorders

A rather 'unique' paper from our lab is online in @cp-cellreports.bsky.social now. Unique in the sense that I don't think anyone else will be rushing to optotag cortical interneurons in the early postnatal brain... because it is nigh on impossible!
