LONP1 regulation of mitochondrial protein folding provides insight into beta cell failure in type 2 diabetes - Nature Metabolism LONP1, whose expression is downregulated in islets from donors with type 2 diabetes, is vital to mediate efficient mitochondrial protein folding, thus preventing proteotoxicity and promoting islet β c...

Type 2 diabetes is often considered a protein misfolding disease. But where are these toxic proteins found? 🤔

🚨In new work out today in @natmetabolism.nature.com, we show that mitochondrial protein misfolding (yes mitos🤯) leads to beta cell damage in T2D. 🚨 nature.com/articles/s42... 1/n

Mark Huising from University of California, Davis, presents research on how dynamic crosstalk within the islet shapes insulin release.

🗣️ Don’t miss today's debate “Are alpha cells and glucagon needed for islet function and glucose homoeostasis?”, chaired by Mark @huisinglab.bsky.social #EISG2025.

Our home-brewed PI3P and PI4P probes in neurons feels like blowing bubbles as a kid: fleeting, a little magical. I’m a Doubting Thomas at ❤️ & why I spend so much time learning to image & build probes. I need to see it to believe it. Too late for #fluorescencefriday but in time for #microscopymonday

Exciting news, although I guess the logic here seems to be that if you can buy genius, why train your own🤔.

Glucagon antagonists, a story of failure (Ant)agonizing over glucose, and the next medical revolution

Well, I'm gonna hold my nose, cover my eyes and published this. A longer form story in two parts, first up glucagon antagonist drugs and briefly why they failed today.

And then next week, glucagon agonists and why they look to succeed. Hope y'all like it!
