*Walking on the tightrope: the shared roles of the bridging pericytes in the brain*

Congratulations Audrey Chagnot!! 🥳

Bias aside, this feels like a really meaningful piece for the cerebrovascular field! 😊

🐭🧠 #PrecapillarySphincters (PS) at the #arteriole–#capillary junction rapidly dilate ~30% in seconds during #SensoryStimulation—regulating #capillary #BloodFlow dynamically. Here we investigated whether they protect downstream microvessels during abrupt #BloodPressure surges 🧪🧵

Microglia modulate the cerebrovascular reactivity through ectonucleotidase CD39 - Nature Communications
Microglia and border-associated macrophages play a role in regulating cerebral blood flow (CBF), but the underlying mechanisms are unclear. Here, the authors show a role for microglial CD39 in the reg...

Mice lacking microglia (Csf1r∆FIRE/∆FIRE) have normal

Typical development of synaptic and neuronal properties can proceed without microglia in the cortex and thalamus - Nature Neuroscience
Microglia are proposed to have a role in brain development through synaptic engulfment and paracrine signaling. O’Keeffe et al. show that certain neurodevelopmental processes attributed to microglia c...

Had a fantastic week at #ANS2024 with Australasian Neuroscience colleagues talking #microglia, #pericytes and #TasmanianDevils. Look forward to seeing you all again in #Hobart for #ANS2025!

Here's a fun one for #FluorescenceFriday. Did you know #marsupials have an entirely different CNS vascular anatomy to most animals? Arterioles and venules enter the brain and branch in unison, terminating at capillary loops. Check out this example from a #TasmanianDevil brain! (1/2)

Here we show how #microglia contact #pericytes and #endothelialcells in the #venule end of the #capillary bed. Note also how a #primarycilium of an #interneuron invaginates the microglia. But why? 🤔 journals.sagepub.com/doi/full/10.... @gazz4science.bsky.social

Lovely new review to help identify features of microglia in EM images!
I like microglia and I like electron microscopy. Today my new review on microglia ultrastructure came out on Open Biology.

I tried to do a guide I wish I had on my PhD. Thankful for all the people that have taught me microglia EM

Calling all #pericyte researchers!

Here's a list of us to start a community on Bluesky. Please feel free to reply to get added and share with your colleagues as more join!

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?

!WELCOME!

thought we might need a starter pack for all those coming over from the birdhouse - here's a GliaSky list.

apologies for missing many of you - please do reply to get added

and remember to repost so the newbies can find us!
