Genetic sex of enteric neurons enables ovarian relaxin to gate maternal gut plasticity Animals must align intestinal plasticity and feeding with reproductive state, yet the checkpoint that gates these adaptations is unknown. Here we show that an ovary-to-enteric-neuron axis gates the on...

📣First preprint of the lab📣 Did that really happen?😅

Enteric neurons, aka somatic postmitotic cells, must hold on to their sex identity tight, to deliver a tuned response to signals from the ovary that instruct the animal to engage sex-matched behavioural programmes.

Our work reveals how the #microbiota helps buffer #malnutrition: L. plantarum sustains intestinal activity of the steroid hormone ecdysone, expanding the midgut and supporting systemic growth.

Thank you so much, Dafni😀😀

Thank you, Julie 😀😀

A nutrient-sensitive enterokine coordinates developmental plasticity through inter-organ signalling Animal survival in fluctuating environments depend on the ability to modulate their developmental pace in response to nutrient availability, a phenomenon known as developmental plasticity. In Drosophi...

Congratulations🥳🥳

Pvf1-Pvr-mediated crosstalk between trachea and gut guides intestinal stem cell migration to promote gut regeneration - Nature Communications Adult stem cells often reside in specialized niches that they exit upon injury. Here they show that in Drosophila, after damage the gut-associated trachea produces the PDGF-VEGF-related ligand Pvf1, which acts as a guidance cue directing ISC migration toward injury sites.

Excited to share our last paper describing how intestinal stem cell migration promotes gut regeneration!

Thank you, bro🙈🙈

Huge thanks to the whole Leulier's team for their support over the past four years😘😘

Glutamine-glutamate intercellular relay model for brain sparing

Our latest preprint…Adrien Franchet, Yuhong Jin et al @crick.ac.uk show that circulating glutamine drives brain sparing during nutrient restriction. Great collab with labs of Yaël Grosjean and Ian Gilmore.

The lab will be represented at #Dros25.
@longweibai.bsky.social presenting in the Physiology session on Friday at 5pm after I give the intro to his talk in a plenary Thursday morning 😉.
#Drosophila #microbiome friends, let’s catch up and go see Longwei ´s talk he has a really cool story to share.

And enjoyed it even more when highlighting it in Cell Host Microbe
