🚨 Paper Alert! In this new work published in @jcellsci.bsky.social we shift our focus on MTFR1L and the feedback loop linking mitochondrial fission, mitophagy and apoptosis. MTFR1L emerges as a critical coordinator of the fission and autophagy machinery.

Rearrangement of amphipathic helices enables lipid uptake at ATG2A N-terminus.
📢 New #preprint from CRN Team Hurley!
The team uncovers the mechanism of ATG2A-mediated lipid transport 🧬
Structural modeling and simulations show that N-terminal helices gate lipid transfer, and a designed mutant transfers lipids three times faster in vitro.

Really happy to see this one out: www.sciencedirect.com/science/arti... Alibek's drive & great coll w/ friends @gekaragoz.bsky.social & E. Hallacli resulted in a cool story that starts with our beloved #Marchantia and ends with iPSC-derived neurons 🤩🤪 A short 🧵
Why do pathological protein aggregates persist in cells and how can we overcome this?
In our new preprint, we show that Tau aggregates fail to initiate selective autophagy and that their autophagic degradation can be restored.

LLOMe has long been used to study lysosomal damage, yet how it works has remained a mystery.
Using cryo-electron tomography, we show it forms amyloid structures inside lysosomes that mechanically rupture membranes – revealing a new paradigm for lysosomal failure.

The compositional analysis of membranes in bulk cellular volumes via AIVE. (A–D)
CRN Team Hurley developed AI-directed voxel extraction (AIVE), a segmentation strategy that refines AI-based organelle boundary predictions. Using AIVE, they identified a previously unknown mitochondrial contact termed the mitochondrial intrusion 🧪

⚡️Mitochondria make ATP, the energy that powers life. But in neurons, with axons up to a meter long, how do these tiny power plants stay functional in the right places? We went looking. 1/n www.biorxiv.org/content/10.6...
Glad to have this finally published: www.sciencedirect.com/science/arti... lots of new data since the #preprint. If you are into selective #autophagy, #evolution, #proteostasis Please have a look!
There are a couple of empty chairs at our table — want to sit with us?

Finally in @nature.com 🎉
We uncovered step-wise mTORC1 activation on membrane: RAG–Ragulator recruits, RHEB pushes closer, and direct membrane contacts by RAPTOR + mTOR trigger full kinase activity.👉 The membrane is not just a platform — it’s part of the mechanism.
