👉🏼👉🏾👉🏻👉🏿👉🏽An opportunity for a PhD studentship in my lab to investigate the mechanisms that mediate the specialization astrocyte endfeet (subcellular compartments enwrapping the vasculature) in collaboration with the magnificent Lorena Arancibia.

Thrilled to announce that our study with C. Calı̀, Marifer Veloz, P. Puchenkov & @deschutteroist.bsky.social is out in #Glia! We explored the properties of the intracellular organization of astrocytes and how the latter influences astrocyte function at their interface with neurons 💫 bit.ly/4ql73Ul

Want to know how endoplasmic reticulum (ER) spatial structure affects calcium signaling in astrocytes? Check our new paper now online in Glia. The placement of IP3 receptors is crucial to determine whether ER close to the membrane amplifies calcium signals. onlinelibrary.wiley.com/doi/10.1002/...

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

Curious about the use of PDE discovery methods for mecanistic multiscale models of cell signaling? Check out our new benchmark paper, work by our amazing PhD student Andréa Ducos: hal.science/hal-05128224 First joint paper with @thomas-guyet.bsky.social! #modeling #PDEs #multiscale #cells #signaling

Sharmila Venugopal and I are delighted to co-edit a collection of video articles showcasing advances in computational neuroscience methods & software. There is still time to submit an abstract! More details here: app.jove.com/methods-coll...

Big week for astrocyte research: 3 new Science papers link astrocytes to behavior. We're excited to add to the momentum with our new PNAS paper: a theory, grounded in biology, proposing astrocytes as key players in memory storage and recall. w/ JJ Slotine and @krotov.bsky.social

Revised preprint out! www.biorxiv.org/content/10.1... We show that most perisynaptic astrocytic processes contain calcium stores and identify the ultrastructural properties of the ER as key regulators of astrocyte function. With C. Calı̀, Marifer Veloz, P. Puchenkov & @deschutteroist.bsky.social

✨ Announcing a new glutamate indicator - iGluSnFR4! ✨

Launched as a pair, iGLuSnFR4s and iGluSnFR4f have high-sensitivity and fast activation/deactivation for recording synapses.

More on the indicators and what they are already revealing: www.biorxiv.org/content/10.1...

Early-life stress induces persistent astrocyte dysfunction associated with fear generalisation Amygdala astrocytes play a critical role in mediating the effects of stress during infancy on neuronal excitability, synaptic plasticity, and memory.

Version of Record of our work at @elife.bsky.social has been published! Super proud of this one after all the hard work of the lab seeing it to the end.
