Happy to see this work finally published π!! A team effort with @AndyShih_Lab!! We show that from birth to old age, #microglia π§ undergo striking shifts in morphology, complexity, and injury response. #liveimaging #neuroimmune #neonatalbrain #agingbrain

It is debated whether poor #blood flow underlies white matter loss in #aging. Our recent study in aged mice supports this idea: Impaired drainage through rare, deep-reaching #venules causes mild #hypoperfusion that triggers inflammation and demyelination.

Very happy to share @stephkbeee's study in @PNASNews on the effects of capillary injury in the brain. Protect those heads!
Stephanie is starting her own lab at @CUAnschutz soon and excited to see her research grow!

Ever wonder if small injuries to capillaries have lasting consequences? Our work exploring this question is now out! None of this would have been possible without the help of some brilliant minds - @NielsonCara @sosamariaj @OrlaBonBon @AndyShih_Lab pnas.org/doi/10.1073/pnas.23β¦

Growth hormone acts on #pericytes, stimulating #angiogenesis and supporting #oligodendrocyte survival & growth after neonatal hypoxia.
An impressive study by the Mei Lab (cell.com/neuron/fulltext/S08β¦) in @NeuroCellPress. Preview written with @vcoelhosantos (cell.com/neuron/abstract/S08β¦)

What makes cerebral white matter more vulnerable with age? In this mouse study, we show that large and rare venules are bottlenecks for blood flow in the white matter. Deep branches of these venules are constricted with age, leading to reduced blood flow.

This mini review was a fun one for @sosamariaj and I where we dove into the mysteries of brain perivascular fibroblasts! Thank you to @AndyShih_Lab for guidance on this one! Please enjoy π!

Mural cell calcium imaging revealed a de-coupling of calcium activity from vessel dynamics in transitional vessels. So, mural cells are signaling but fail to translate these signals into contraction/relaxation.

Capillary injuries and regression are hallmarks of many neurological diseases, but they are exceedingly small and evade detection by most clinical imaging. Studies in animal models can help us understand how small injuries produce outsized effects through their remote actions.

Another wonderful study led by post-doc and K99/R00 fellow @stephkbeee, supported by PhD student @NielsonCara and lab manager @sosamariaj.
@stephkbee is on the faculty job market. A world-class two-photon imager and so much more!

It's all connected... In this study, we show that tiny injuries created deep in the brain's capillary bed can contribute broadly to blood flow impairment by constricting upstream supply vessels. biorxiv.org/content/10.1101/β¦

Focal capillary injuries were made using precision laser ablation, and the effects of these injuries were carefully monitored across vascular zones.

Selective and long-lasting constrictions were seen in transitional vessels, located hundreds of micrometers upstream, particularly when injuries were severe enough to cause capillary regression. These transitional vessels are the "spigots" for flow into the capillary bed.

We team up with @drew_lab_nvc to examine anatomical and functional changes in aged mouse brain. We found that aging induces selective regional vascular and pericyte degeneration, slowed NVC response, and lower oxygen carrying capacity.

The first review from the @vcoelhosantos lab! Surprisingly little known about how early life hypoxic events affect cerebrovascular function and resilience in adulthood.

Does perinatal intermittent hypoxia affect cerebrovascular network development?
Unfortunately, we donβt have the answer yet but we have a hypothesis! @AndyShih_Lab
