Happy to announce that our latest paper is now out! Have you ever wondered how neural tissues control their size? In this paper, we show that cell division orientation is critical in both the cortex and retina. www.science.org/doi/10.1126/...

New preprint from Xhoela Bame et al shows that dying oligodendrocytes stick around for weeks to months without mitochondria! This happens after single cell DNA damage or when mitochondrial Fis1 is deleted in oligodendrocytes. www.biorxiv.org/content/10.6...

Super excited to share this new paper led by @sejpaton.bsky.social that I briefly mentioned at #ACNP2026 yesterday! 🧪🧠🤓 We tested preventive strategies to protect the brain vasculature #BBB during stress exposure, mix of mouse 🐭 and human data So proud of my team 🤘 www.nature.com/articles/s41...

🚨 PI position in dept. of Neuroscience with lab located the @crchum.bsky.social Hiring at assistant/associate prof level in the fields of neural regeneration, stem cells and spinal-associated pathologies can-acn.org/professor-re...

We identified how mechanical forces shape myelin development. The TMEM63A channel in oligodendrocytes converts physical cues into molecular signals that control myelin growth. Oligodendrocyte mechanotransduction channel TMEM63A regulates myelin sheath geometry: Neuron www.cell.com/neuron/fullt...

New Year, new paper from our lab. Emily Kramer used 3D light-sheet imaging and tissue clearing to examine the spatial architecture of mouse amygdala engram ensembles. onlinelibrary.wiley.com/doi/10.1002/...

“Basic neuroscience hasn’t produced new drugs.” 💊 Not true - zuranolone (PPD), suzetrigine (pain), gepants (migraine), and more... were born out of a long arc of studies in the lab. I wrote a Perspective on why this matters. @thetransmitter.bsky.social www.thetransmitter.org/drug-develop...

Alicia Pietramale et al. discovered a disconnection between microglial processes that surveil or respond to acute damage and those that contain mitochondria. Cytoskeletal components and metabolic enzymes underlie these differences. Final version just published! www.nature.com/articles/s41...

Our new paper showcasing molecular connectomics with pan-expansion microscopy is out in @natbiotech.nature.com! www.nature.com/articles/s41... This wonderful collaboration with @bewersdorflab.bsky.social was led by Ons M'Saad (now founder/CEO of Panluminate) and @allisonphysics.bsky.social. (1/5)

Our latest paper is out! While the circadian photoentrainment circuit has been extensively studied, the mechanisms regulating its development remain poorly understood. Here we show that retinal Müller glia play a key role in this process. Check it out! www.sciencedirect.com/science/arti...

Excited to share the latest from the lab on the molecular mechanisms of silencing and un-silencing a hippocampal engram ensemble. Was fun using a variant of the EPSILON technique developed by Adam Cohen's lab. (1/2) www.sciencedirect.com/science/arti...

I am proud to share our work on X-linked Dystonia-Parkinsonism — a rare neurodegenerative movement disorder driven by a SINE-VNTR-Alu retrotransposon insertion in the TAF1 gene. Read our two companion papers: 🔹 www.biorxiv.org/content/10.1... 🔹 www.biorxiv.org/content/10.1... 🧵 Highlights below!

New paper from the lab 🚨 Led by Ali Golbabaei, this study explores the how the composition of prefrontal cortical engrams changes with memory age: authors.elsevier.com/a/1lzT-3BtfH...

In the desert of tools to manipulate oligodendrocytes in the brain, we built an OASIS. 🌿 Pun intended. I’m still in awe every time I spot an amazing-looking cell. The beauty of OL and myelin never fails me! Hope this tool helps more people see it too.

Just out in Nature! “The astrocytic ensemble acts as a multiday trace to stabilize memory.” We identified astrocytic ensembles that link experiences across days to stabilize memory nature.com/articles/s41.... New astrocyte tools are openly available at Addgene: addgene.org/Jun_Nagai/. 1/8

Thrilled to share this work from my postdoc with Tom Carmichael, available online @ Neuron! Long story short: we find even more evidence that all reactive astrocytes are not equal, and we can take advantage of those differences to improve repair after stroke. www.sciencedirect.com/science/arti...

Huge congrats @amygleichman.bsky.social on this phenomenal study, demonstrating regional differences in astrocyte responses to stroke and a key role for astrocytes in post-stroke angiogenesis and repair! (see also - gorgeous astrocytes for fluorescence Friday) www.sciencedirect.com/science/arti...

1/11 Though it's personal, I’m sharing this analogy if it helps others: In the last few weeks, I’ve been thinking a lot about my past journey with cancer. Years ago, I found out in the worst way. My doctor accidentally released the biopsy results to my online patient portal. 🧵 Thread
