IL-22 from enteroendocrine cells promotes early-life gut motility in zebrafish through the microbiota The gut microbiota, immune system, and enteric nervous system interact to regulate adult gut physiology. However, the mechanisms establishing gut physiology during development remain unknown. We repor...

Very happy to share this study from our group and colleagues now out in Science!
We found that in zebrafish, before the immune system is mature, gut epithelial cells perform immune functions by producing the cytokine IL-22 to shape the microbiota to promote early life gut function

🌟 Meet the Scientific Committee: @filodelbene.bsky.social 🌟

Filippo del Bene is a member of the Scientific Committee of #EZM2026, and we are thrilled to have him join us in Vienna!

Stay tuned as we continue to introduce the outstanding scientists of EZM2026! 🐟🧬

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!

Proud to share our new paper uncovering how Lrrn-mediated targeting of retinal ganglion cells assembles circuits for brightness and contrast detection — led by my outstanding PhD student Elena Putti and made possible through wonderful collaborations. www.science.org/doi/10.1126/...

Blue-lined octopus Hapalochlaena fasciata males envenomate females to facilitate copulation Chun et al. show that in the blue-lined octopus Hapalochlaena fasciata males envenomate females during copulation, most likely as a defense against being cannibalized.

This article truly refines the concept of a toxic relationship. www.cell.com/current-biol...

Myosin 1b regulates intestinal epithelial morphogenesis via interaction with UNC45A Revenu et al. show the function of myosin 1b (Myo1b) in intestinal epithelia. In human cells, MYO1B is part of the UNC45A interactome and contributes to lumenogenesis by modulating spindle orientation in vitro. In zebrafish Myo1b is important for intestinal epithelium folding during the development of the intestinal bulb.

super cool work showing important role for Myo1B, an UNC45A binding partner, in several aspect of intestinal morphogenesis!
