New preprint @biorxiv-devbio.bsky.social by Harshath Amal and colleagues from our lab @uni-muenster.de shows how a BMP #morphogen gradient is translated into graded junctional permeability by tuning adhesion and actomyosin contractility in #Drosophila

Spotlight: Ball and Röper @pdncambridge.bsky.social discuss recent findings by Almasoud, Franz et al. (rupress.org/jcb/article/...) describing how apical–basal polarity regulates cell–cell adhesion in the #Drosophila fat body. rupress.org/jcb/article/...

#Adhesion #Cytoskeleton #Development

Our take on a really interesting new study by the Franz lab at UCL, a version of epithelial polarity where you would not expect it! Read our Spotlight and the original paper!

Great spotlight by @katjaroeper.bsky.social on very interesting work by the Franz lab on epithelial-like polarity in nonepithelial fat body cells in #Drosophila

Dirty little secret about #Drosophila transgenes: pUAST transgenes are downregulated by nonsense-mediated mRNA decay. Deleting the pUAST 3'-UTR can boost expression ~10x.

Awesome!

Great news! The next JEDI #Drosophila conference is now officially @embo.org funded! We are more than grateful for the support!

How can embryos use pulsatile contraction to shape tissue development during morphogenesis? I'm @weiyiqian.bsky.social and with this thread I want to introduce the roles of pulsatile actomyosin in animal development and the mechanisms that drive actomyosin to pulse

How can structures at the vertex of 3 cells have effects at the tissue level?

Join me, @laura-rustarazo.bsky.social, to explore how tricellular junctions (TCJs) act as local tension sensors and regulators of global tissue organization. 🧵⤵️ doi.org/10.1126/scie...

Okay, Thread 1.

In making this, I realized that in order to really, explain mouse DV axis, I need to first talk about some other stuff and some overlap with mouse AP axis development, so it might actually be next week that we talk about DV axis fully but let's see how far we get today! (1/n)

Mark your calendars, the Signaling by Adhesion Receptors GRC is June 7 - 12, 2026. We have a terrific program that balances developmental biology, cell polarity, and adhesion and signaling.
