📣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.

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...

Excited to share our last paper describing how intestinal stem cell migration promotes gut regeneration!
www.nature.com/articles/s41...
loading . . .
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.
