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 https://t.co/3ncBYc1vhv
Growth hormone acts on #pericytes, stimulating #angiogenesis and supporting #oligodendrocyte survival & growth after neonatal hypoxia.
An impressive study by the Mei Lab (https://t.co/Tzt4WV0BBv) in @NeuroCellPress. Preview written with @vcoelhosantos (https://t.co/fxXwWGbVDl)
@stephkbeee @SiegenthalerLab @sosamariaj @NielsonCara@stephkbeee, it's so exciting to see your dream come true after all the long hours in the lab. You will be an amazing PI and I'm excited to see your research grow! Prospective trainees, keep your eyes on the future Bonney lab for cool imaging projects!
@OrlaBonBon@stephkbeee Orla, it was so much fun that the time flew by too quickly. The van Veluw lab is very lucky to have such a great scientist and thoughtful team member!
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.

@AmrnMughal Thank you Amreen! Also, I see you have started your new lab! You deserve the REAL congrats! Happy to talk imaging and veins/venules in the future.
@alankrit97 Thanks Alankrit. It's possible that some out of focus damage occurred, but if the concern was inadvertent, direct damage to arterioles, it is less likely. The selected capillary targets were not underneath pial vessels, and distant from the transitional zone in the x-y dimension.
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. https://t.co/D38oMFbIwD
