Vascular endothelial cells in the central nervous system (CNS) form a barrier that restricts the movement of molecules and ions between the blood and the brain. This blood-brain barrier (BBB) is crucial to ensure proper neuronal function and protect the CNS from injury Pericytes and the blood-brain barrier: recent advances and implications for the delivery of CNS therapy. Armulik A, Mäe M, Betsholtz C. "Once the regulation of brain endothelial transcytosis is understood at the molecular level, it should be possible to exploit these mechanisms as targets for facilitated CNS drug delivery". PMID: 22826851 blood vessels occurs by induction of migratory endothelial tip cells in pre-existing vessels. These Pericytes and the blood–brain barrier: recent advances and implications for the delivery of CNS therapy “Once the regulation of brain endothelial transcytosis is understood at the molecular level, it should be possible to Brain endothelial cells are the major components of the blood-brain barrier (BBB), but the surrounding astrocytes and pericytes are important in the induction and maintenance of BBB function. 2015-04-17 · Pericytes are required for blood-brain barrier integrity during embryogenesis. Nature.2010;468: 562–566.
2020-01-11 · Pericytes are partially sandwiched between endothelial cells and astrocyte end feet and represent important constituents of the neurovascular unit, and they have traditionally been considered essential for normal blood–brain barrier function [ 3 ].
Pericytes play a crucial role in the formation and functionality of the blood–brain barrier. This barrier is composed of endothelial cells and ensures the protection and functionality of the brain and central nervous system. It has been found that pericytes are crucial to the postnatal formation of this barrier.
Pericyte-endothelial interactions are particularly prominent for blood-brain barrier (BBB) maintenance, with profound effects on basement membrane and endothelial tight junction structure and function. Pericytes regulate the blood–brain barrier Abstract.
Targeting pericytes som ett sätt att öppna BBB för läkemedelspassagen skulle vara ologisk (eftersom dessa celler ligger på hjärnans sida i stället för barriärens

It has been long assumed that this physical barrier is created largely by endothelial cells (ECs) in the central nervous system (CNS), while the role of pericytes (PCs), i.e., mural cells that surround and stabilize these vessels, has remained more enigmatic. In fact, it has
2020-07-28 · Formation, maintenance, and repair of the blood–brain barrier (BBB) are critical for central nervous system homeostasis. The interaction of endothelial cells (ECs) with brain pericytes is known to induce BBB characteristics in brain ECs during embryogenesis and can be used to differentiate human ECs from stem cell source in in vitro BBB models.

Blood–brain barrier pericytes regulate paracellular flow between cells, transendothelial fluid transport, maintain optimal chemical composition of the surrounding microenvironment, and protect endothelial cells from potential harmful substances.
