A fun (AI-enhanced) image of 12187 ABR waveforms. We used these data from our own lab and several others to train ABRA (PMID: 38948763) and are still using it to train next-gen machine learning models for cochlear studies. Stay tuned (no pun intended) for more!

As Fran was nice enough to highlight this, I thought I'd put up a brief thread. 3 in 10 proteins that our cells make are either embedded in membranes (ion channels, adhesion molecules, etc.) or secreted (insulin, antibodies). They move through the secretory pathway. 1/

simple diagram of the secretory pathway.

Exciting preprint from the @merz.bsky.social lab proposing how fidelity of membrane fusion is achieved #membranes #trafficking

Does anyone understand how the AC meeting is literally the day after Study Section? Don't they need summary statements for this? I have been refreshing my commons page every minute to see if there is a score/summary statement, but in reality this would be unprecedented speed? What am I missing?

So excited to see Yasmin’s beautiful paper is finally out! We hope this tool will be useful for everyone studying stereocilia bundles (including companies developing gene therapies). I fantasized about having an AI tool like this when I was a grad student. All the code and data is open source.

Cochlear hair cell #stereocilia bundles are vital for hearing, but what is their 3D morphology? @manorlaboratory.bsky.social present VASCilia, a tool that automates analysis of 3D #ConfocalMicroscopy datasets of phalloidin-stained #CochlearHairCell bundles @plosbiology.org 🧪 plos.io/3NSHdYW

The algorithm successfully detects stereocilia bundles in 2D across successive frames, assigning unique IDs to each detected object within the 2D plane (left). The variation in IDs across frames reflects the independent detection process in each 2D frame. Subsequently, a multi-object assignment algorithm (middle) intervenes to reconcile these IDs, effectively re-assigning them to maintain consistency across frames. This step is crucial for reconstructing accurate 3D objects (right), ensuring that each bundle retains a consistent ID throughout all frames.

I'm so happy to have gotten the opportunity to work on this project and I'm SO excited that they selected our image for the cover!

This one was quite the journey! The paper describing the #ChlamyDataset is finally out and on the cover of Mol Cell! This beautiful rendering made by co-author @jessheebner.bsky.social and Holly Peterson shows an instance of mitochondrial fission found in the dataset 😍 [Maybe long thread ahead]

Initial submission of a grant received a 15%-ile score. But we had to submit as new since the PAR expired. We submitted an even stronger, but just slightly modified version to address any/all weaknesses in the prior summary statement. Just found out it was "Not Discussed"😱

Can someone please connect me with someone at FDA CDER (or with expertise thereof) to discuss the pathway to approval for n-of-1 & n-of-many ASOs? I've got some pretty technical questions too involved to describe here.

Flagellar length control in Chlamydomonas is a paradigm for organelle size regulation. In poster 163 at CellBio2025 Sunday Dec 7, I present work by Hiro Ishikawa using a synthetic biology approach to test a length-sensing model based on diffusion of kinesin in flagella

Flagellar length control in Chlamydomonas is a paradigm for organelle size regulation. In poster 155 at the CellBio2025 meeting Sunday Dec 7, Ximena Garcia Arceo uses Lithium, which increases intraflagellar transport, as a tool to probe how length-altering mutants work.

As someone with Connexin-26 (GJB2) mutations, I've managed to so far study most forms of hearing loss that do NOT involve GJB2. As a cell biologist, I've managed to study ER-organelle related processes and disorders with minimal connection to hearing loss. Now this paper drops.

15 years in the making, we confirmed that mitochondria - the powerhouse of the cell - have an unusual localization in patients who experience psychosis (including schizophrenia and bipolar disorders). You’ll never guess what kind of patient cells we used to make this discovery… 🧵

mitochondria from bipolar patients are closer to the nucleus in these images; control patients' are spread out further
