When the stars of glial scar borders and stroke recovery “have a baby”, it gives this 😅 #astrocytes #stroke #cerebrovascular
Regionally mapped astrocytic responses to cortical and white matter stroke show differential roles in astrocyte-induced vascular remodeling
Stroke is a major cause of disability. Astrocytes respond to stroke in a gradated manner, but details of that response and its consequences for tissue…

Very cool new paper by @thegulab.bsky.social published in Cell, showing that arterial endothelial coupling via gap junctions determines the speed and spread of vasodilation induced by neuronal activity ! #cerebrovascular #bloodflow #endothelium
Brain endothelial gap junction coupling enables rapid vasodilation propagation during neurovascular coupling
Vasodilatory signals are rapidly communicated across long distances by endothelial-endothelial
gap junctions, enabling coordinated dilation of the arterial network during neurovascular
coupling.
