Direct labeling of microtubule turnover reveals in-lattice repair and stabilization patterns in developing neurons The microtubule cytoskeleton is the backbone of neuronal morphogenesis, driving the development of the dendrites and axon, and supporting trafficking to distant compartments. How neuronal microtubules...

🚨The Neurocyto lab is branching out in our latest preprint! We used tubulin microinjection to directly visualize microtubule turnover in developing hippocampal neurons, demonstrating the presence of in-lattice repair and a selective stabilization in the nascent axon. Check below, or read on 🧵 1/9

Happy to finally share the amazing results of our long-term collaboration with Karin Reinisch’s lab on how bridge lipid-transfer proteins (BLTPs) cooperate with partner proteins to orchestrate lipid delivery. A quick thread (1/7)

I 2nd this. Also, the way some methods just say something like “as prepared in (insert ref)…” then when I look at the reference and it says the same thing but a different reference. Also, half the time the method wasn’t even described well.

Woot. Glad our work made it to your JC!

Membrane editing with proximity labeling reveals regulators of lipid homeostasis - Nature Chemical Biology Coupling an optogenetic lipid-modifying enzyme with proximity labeling reveals protein networks and mechanisms regulating lipid homeostasis in the membranes of target organelles.

Thrilled to share our latest study, led by @reikatei.bsky.social, in @natchembio.nature.com! We began by asking a simple question—how do cells know if they have too much of a lipid in a particular membrane, and how do they respond to rectify this imbalance?

Latest preprint from our lab reports that the distinct pH of anterograde (less acidic) and retrograde (more acidic) lysosomal vesicles in the axon depends on assembly of the V1 and V0 domains of the vacuolar H+ ATPase, mediated by the metazoan RAVE complex www.biorxiv.org/content/10.6...

Final version is out! Our large-scale cryo-ET dataset 🔬 of Chlamydomonas reinhardtii 🦠 is now published in @cp-molcell.bsky.social

Huge collaborative effort! So glad to see the community already using it to develop new resources & tools.

Our lab’s paper spearheaded by Keni and pushed to completion (and satisfaction by the reviewers) by Satish is finally out www.nature.com/articles/s41.... Was so fortunate to contribute to this project and learned a lot in both neuronal cell biology and cryoET. Also, Satish is on the job market!

Architecture of the human KICSTOR and GATOR1–KICSTOR complexes Nature Structural & Molecular Biology, Published online: 06 November 2025; doi:10.1038/s41594-025-01693-4Teng and Zeng et al. use cryo-electron microscopy to show that the crescent scaffold of KICSTOR anchors GATOR1 to lysosomes and disruption of the interaction causes mTORC1 hyperactivation and TFE3 mislocalization. KICSTOR enables nutrient-dependent mTORC1 regulation by binding anionic lipids for lysosomal targeting.

FSP1-mediated lipid droplet quality control prevents neutral lipid peroxidation and ferroptosis - Nature Cell Biology Lange et al. identify a lipid droplet quality control pathway in which FSP1 safeguards stored neutral lipids from lipid peroxidation, thereby preventing the induction of ferroptosis.

Excited to share our study out in @natcellbio.nature.com! Led by @mikelangelipid.bsky.social, we identify the first #LipidDroplet lipid quality control pathway: LD-localized FSP1 protects stored lipids from oxidative damage and prevents LD-initiated #ferroptosis.

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control.
