Astrocytic opposition for this #FluorescenceFriday, Cytoskeleton vs. Cytoplasm. ⚪️GFAP 🟠eGFP 🔵DAPI Imaging credit: undergrad Camila Cabarcas

Couldn't wait for Friday to share this really incredible image from superstar undergraduate student Camila Cabarcas, iInvestigating astrocyte morphology Fingers crossed for Camila as she's at U Cincinnati this week to interview for grad school!

Delighted to share our first preprint of the year! A project that we're all really proud of in the lab led by @ossamaghenissa.bsky.social with @mathiasgua.bsky.social in which we set out to test the role of basolateral amygdala astrocytes in anxiety behaviour. www.biorxiv.org/content/10.6...

Went fishing for this #FluorescenceFriday (GCaMP6s zebrafish larvae)

The views we are lucky to witness from the @crchum.bsky.social

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 our new study showing microglia prune astrocyte processes in adult brain, to regulate synaptic transmission, hypothalamic neuron activity, and salt-induced hypertension in🐀. Huge team effort - congratulations to all🥂🍾🎉

Go Lewis 👏👏👏

Sleep loss is a metabolic disorder "This review describes how sleep deprivation increases resting energy expenditure, leading to the development of a negative energy balance in highly active cells like neurons." www.science.org/doi/10.1126/...

Happy to see that the 2nd part (2018 to 2021) of my postdoc work is now out as a preprint.

@lewisholt.bsky.social sharing some cool data about astrocytes driving stress-induced behaviour! #astroglia

Very happy to share several common protocols used in our lab for the second edition of the book "Astrocytes: Methods and Protocols" @lewisholt.bsky.social @astroantho.bsky.social Thanks @dibenedetto-lab.bsky.social for being a very patient editor! link.springer.com/book/10.1007...

Montréal glia people / neuroscience community - I'm hosting Jun Nagai (RIKEN) on April 2nd at the @crchum.bsky.social If you're interested see details below, or reach out to me! Open to all.

Not sure if our 'striking image' we submitted will get used but here it is. Super striking, if you ask me! Credit - @mathiasgua.bsky.social

Very honoured to be named the researcher of the month by SENSUM - the mental health and neuroscience strategy at @umontreal.ca www.sensum.umontreal.ca/en/2025/01/3...

Astrocyte physiologists and computationalists! Imaging astrocyte structure and function, we discovered and quantified a spatial threshold to astrocyte calcium surge ⭐ doi.org/10.7554/eLif...

A touch of blue velvet LUT with this #FluorescenceFriday GCaMP8 astrocytic activities at the 2p

How convenient - this tree already comes with ornaments! 🎄🧪 Get into the holiday spirit with this beautiful cell tree by @oozguc.bsky.social from @ibecbarcelona.eu. This beautiful fusion of science and art was made using our Lamin B1 stem cell line! What would you want to see under your cell tree?

Delighted to share an update to our preprint, reviewed at @elife.bsky.social, and now sent back for re-review. Colossal work by the team and driven home by @mathiasgua.bsky.social Quick 🧵 of what's new - www.biorxiv.org/content/10.1...

we haven't talked about this in the SKY> exciting preprint from Kevin Guttenplan in Marc Freeman's lab at @volluminstitute.bsky.social Adrenergic signaling gates astrocyte responsiveness to neurotransmitters and control of neuronal activity www.biorxiv.org/content/10.1...

10/ Why should you bring #preprints into your journal club? Here’s what #ECRs stand to gain by looking beyond published papers. https://buff.ly/3VbvNjT

New paper from our neighbours Stephanie Fulton’s lab investigating microglia, inflammation and synaptic transmission in the NAc. www.biorxiv.org/content/10.1...

some great starter packs for the #glia, #astrocyte, #oligodendrocyte, #microglia, #neuro researcher: gliasky, astrocytesky, microglia But if you also like interactions between celltypes, please help this starter pack get started. Maybe someone can connect all of us in a feed? go.bsky.app/MHtJzeC

Not sure I have any good pictures in the back pocket to beat the calcium imaging from @mathiasgua.bsky.social Instead for my first post on Bluesky I want to share the CANglia webinar: trainee series!

Still thinking about which neuroscience conferences to attend next year? Explore our events page, featuring a curated list of top neuroscience meetings with topic-based filters. Plus, check out upcoming webinars compiled by @worldwideneuro.bsky.social. thetransmitter.org/events

Interesting to see how this is all shaping up! I’m still really proud that the first data paper from my lab went into eLife with the new model, which I think is a great system. (We’ll be updating the manuscript based on these reviews in the very near future)
