Delta/Notch signaling level is decoded through transcriptional burst duration during muscle progenitor specification

Emma Leroux, Olivier Josse, Savannah Moinet…·Hadi Boukhatmi

The paper shows that muscle progenitors decode Notch signaling levels through transcriptional burst duration, with higher Delta levels leading to stronger Notch signaling and distinct transcriptional outputs.

SPARC mediates tumour-stroma intercellular communication through endosomal regulation of Delta and Notch signalling

Aurélien Guillou, Nourhene Ammar, Olivier Josse…·Hadi Boukhatmi

This study identifies SPARC as a mediator of tumour-stroma communication by regulating endosomal Delta and Notch signalling in a Drosophila cancer model.

Immune vascular dialogue coordinates muscle maintenance following damage in Drosophila

Nourhene Ammar, Olivier Josse, Aurélien Guillou…·Hadi Boukhatmi

This study identifies a novel immune-vascular communication program in Drosophila that coordinates muscle maintenance after damage through macrophage-derived signals and ECM organization.
