#EMBORegeneration2026
📚Take-home message: Axonal regeneration is more than growth. It’s also about the cellular environment.

Why does this happen? 🔎 A gliofibrotic scar forms at the injury site, an injury response typically associated with mammals.
So the axons keep growing, but they physically and chemically can’t overcome the barrier. The result: permanent vision loss.
A new preprint from our lab is out! 🥳 Congrats to Anyi Zhang and @lucamasin.bsky.social for this great paper titled: Repressed mTORC1 signaling and transient dendritic pruning support axonal regeneration! Grateful for the fruitful collaboration with the @filodelbene.bsky.social and Poulain labs!
Adult killifish — both young and old — fail to reinnervate their brain target after complete optic nerve transection. 🐠🧠👁️
This is surprising, as most teleost fish are able to fully restore neural circuitry and regain visual function after this type of injury.
Even more intriguing: the retinal ganglion cells in killifish retain their intrinsic growth potential. 🧐
However, instead of navigating towards the brain, they misdirect and loop within the retina (yellow arrowheads).
To reduce the extensive scarring, we performed a partial optic nerve transection in young adults, leaving a portion of the nerve uninjured.
This approach indeed limited scar formation, and it allowed regenerating axons to reach the brain and reinnervate their targets. ✅
🚨Paper Alert!
Check out our latest work, now published in @FrontiersNeuroscience. We show how this remarkable fish surprisingly displays mammalian-like injury responses after optic nerve transection.

🚨New preprint out!🚨
I’m excited to share the latest work by Anyi Zhang and me, which shows that mTORC1-dependent transient dendritic pruning is essential for efficient axonal regeneration in spontaneously regenerating zebrafish neurons.
