Blood-Brain Barrier Overview: Structural and Functional Correlation
Brain endothelial cells exhibit a unique phenotype when compared to cells from other vascular regions. They have luminal/abluminal polarization, tight junctions, junctional adhesion molecules (JAMs), and specific transport mechanisms for limiting polar substances [33, 34].
The blood–brain barrier: Structure, regulation and drug delivery
May 25, 2023 · BBB is a natural barrier protecting the brain from the entrance of toxins and pathogens. However, intact BBB consisted of endothelial cells and tight junctions impedes the brain permeability of...
The Evolving Concept of the Blood Brain Barrier (BBB): From a …
Several barriers of the CNS, including the cerebral endothelial cells (CECs) of the blood brain barrier (BBB) tightly regulate transport into and out of the CNS. An early indication of a barrier at the cerebral blood vessels was recorded by Ridley (1653–1708) after injecting wax and mercury, resulting in three-dimensional vessel casts.
