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. nature.com/articles/s4159…

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/pn…


















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. biorxiv.org/content/10.110…





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/10.110…
