Dear #Drosophila and #NewPI community, the mentee survey for this great mentorship program is still open!

Shefali@iamshef.bsky.social · 4w ago

Hey #Drosophila folks - the #flycross #mentee survey is open for #grad students, #postdoc and #pretenure faculty. ~95 mentors from across the world, with diverse expertise. The co-chairs @shyama13.bsky.social and @jocmcdonald.bsky.social have done a phenomenal work in taking the program forward 🎉

I am excited to share our work, recently published in PLOS Biology, in which we uncover a mechanism by which intestinal stem cells (ISCs) recognise pathogenic bacteria following infection and promote intestinal regeneration. journals.plos.org/plosbiology/...

Recognition of pathogenic bacteria by intestinal stem cells promotes adult Drosophila midgut regeneration

Bacteria infecting the intestinal epithelium are recognized by epithelial and immune cells, however the role of intestinal stem cells (ISCs) remains unclear. This study shows that adult Drosophila mid...

Now out in Annu Rev Cancer Biol: "Beyond Mice and Men." We think of cancer as a disease of humans, as well as pets 🐈‍⬛ 🐕 & lab mice. But cancer is found across the animal tree of life, including clams and fruit flies. Comparative oncology has a lot to teach us. 🧵 www.annualreviews.org/content/jour...

Beyond Mice and Men: Alternative Vertebrate and Invertebrate Models in Cancer Biology

While cancer looms large in the public and scientific minds, this can result in a quite narrow view of its range and manifestations. The centering of human clinical investigations and the popularity o...

Animals can modulate the pace of their #development when #nutrition is limited, but how? This study in #Drosophila larvae uncovers a nutrient-sensitive gut–brain endocrine circuit that slows development and enhances survival under fluctuating nutritional conditions. 🧪 #AcademicSky plos.io/4z9O8QG

Schematic model illustrating the gut–brain axis regulating larval adaptation to nutritional stress.
Compared with normal fed conditions, undernourished germ-free (GF) status or severe malnutrition associated with LpWJL induces Lst expression in a small population of midgut EECs. Once induced, gut-derived Lst acts systemically to suppress the circulating levels of dIlp2. This EEC-specific Lst up-regulation is triggered by reduced amino acid availability through a multi-organ relay involving the fat body and IPCs in the brain. Consequently, Lst orchestrates a feedback control loop that temporarily attenuates developmental progression upon sensing systemic nutrient shortages. This bidirectional gut–brain axis ultimately enables Drosophila larvae to preserve viability under severe nutritional stress. Created in BioRender. Leulier, F. (2026) https://BioRender.com/.

Excited to share our new work in The EMBO Journal! We show that intestinal stem cells directly sense tissue damage via phosphatidylserine on dying cells, activating Draper-Src-Shark-STAT signalling to drive their proliferation and shape local tissue responses to promote regeneration.
