Cells of the blood–brain barrier: an overview of the neurovascular unit in health and disease

HL McConnell, A Mishra - The Blood-Brain Barrier: Methods and Protocols, 2022 - Springer
The brain is endowed with highly specialized vasculature that is both structurally and
functionally unique compared to vasculature supplying peripheral organs. The blood–brain …

Precapillary sphincters and pericytes at first-order capillaries as key regulators for brain capillary perfusion

SA Zambach, C Cai, HCC Helms… - Proceedings of the …, 2021 - National Acad Sciences
