I feel the science-to-nonsense ratio is much better on this site:

We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji.

It ships many new features, detailed below, but that are articulated around the following:

Pleased to share my latest review article with @tandfresearch.bsky.social, taking a deep dive into neuronal autophagy, how Huntingtin coordinates it, and how the process goes awry in Huntington’s disease.

Always exciting when a dissertation chapter makes it to publication.

Thrilled to share this work in Cell Death & Disease, exploring putative roles of GSK3β and ERK1 phosphorylation in Huntington’s disease.

Full article: doi.org/10.1038/s414...

Huge thanks to all co-authors & contributors! 🦾

Do you want to hear the latest and greatest about the neuronal cytoskeleton? Join us in Chile next April for #NeuroCyto2025, organized by @monicamsousa.bsky.social, Kassandra Ori-McKenney and Tomás Falzone! Registration is open until March 5: neurocytoskeleton.com/2025/

Exciting work! 🎉
Nucleoids are known to be regularly spaced along mitochondria, important for their inheritance and maintenance of the local proteome. We identified pearling, a Plateau-Rayleigh type instability described since the 1980s, to be responsible: t.ly/KKmGK. Collab with JLS lab @hhmijanelia.bsky.social

Likely my final #FluorescenceFriday post of 2024! 🔬

Here’s a kinetic showcasing pkMito dynamics and the heterogeneity of axonal mitochondria

I'm looking forward to all of the incredible microscopy from this community in 2025.

Happy Holidays everyone! ☃️❄️

Some #MicroscopyMonday to kick off the week! 🔬⛄

I paired #lysosome and #mitochondria kinetics side-by-side to highlight their distinct axonal motility.

I thought this nicely shows the need for organelle-specific metrics when designing high-throughput screening assays.

The cell biology team at ALS Therapy Development Institute will be sharing some exciting work today at the 2024 International Symposium on ALS/MND. #endALS #Neuroscience #CellBiology

If you're here in Montreal, come chat with us during theme05: human cell biology and pathology (details below): 🧵

Important article that challenges the classic view of axons as simple tubes. To what extent they fluctuate in diameter is up for debate - see some thoughts in this commentary piece in @science.org. Exciting time for axon scientists!

Axonal mRNA studies always catch my attention.
Great preprint from the Redemann and Hermann labs: www.biorxiv.org/content/10.1...

". . . only very few studies have paid attention to the important roles of distinct mRNA expression profiles of the axon and soma . . ." #MoreAxonSeq #Neuroscience

Sharing #FluorescenceFriday early before the food coma hits this weekend! 🦃

Here are longitudinal kinetics showing dose-dependent degeneration from an exogenous stressor: part of an assay developed for drug screening with iPSC-derived neurons. 🔬

My turn to create a starter pack for scientists using live imaging in their research! Of course, I’ve likely missed many—please let me know who else I should include. Thanks!

Some highlights from optimizing AAV transduction efficiency of an FL-reporter in iPSC-derived motor neurons.

Excited about striking a balance between sparse-labeling and 'painted' coverage.

glia (cyan) migrate out of organoids and completely steal the show from neurons (green) and their axons (magenta) 🔬
