Cerebral pericytes constitute an essential component of the blood‐brain barrier (BBB) and are involved in blood vessel assembly. Recently, we reported on the induction of a BBB‐specific enzyme expressed by cerebral pericytes (pericytic aminopeptidase N/pAPN) in coculture with cerebral endothelial cells. Keywords Pericytes Blood–brain barrier Brain endothelial cells Astrocytes Co-culture In vitro BBB model (rat) Permeability Transendothelial electrical resistance Introduction The endothelial cells in the blood vessels of different organs possess different characteristics, regulated by speciﬁc local signals. Brain capillary endothelial cells 2021-03-19 · Recent work suggests that the leak in the blood-brain barrier that occurs with Alzheimer's may be due to an age-related loss of pericytes.

Pericytes maintain the integrity of the BBB and degenerate in Alzheimer’s disease (AD). Blood-brain barrier-associated pericytes internalize and clear aggregated amyloid-β42 by LRP1-dependent apolipoprotein E isoform-specific mechanism Pericyte, Astrocyte and Basal Lamina Association with the Blood Brain Barrier (BBB) The periendothelial accessory structures of the BBB include pericytes, astrocytes, and a basal membrane. The endothelial cells of the BBB are distributed along the length of the vessel and completely encircles the lumen. 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.

The endothelial cells are surrounded by pericytes and astrocytic endfeet which are of pericytes for small-molecular drug transport across the blood-brain barrier a closer insight into different aspects of transport in a pericyte-deficient state. The aim of the thesis was to examine the role of pericytes for small-molecular drug transport across the blood-brain barrier BBB , by providing a closer insight Targeting pericytes som ett sätt att öppna BBB för läkemedelspassagen skulle vara ologisk (eftersom dessa celler ligger på hjärnans sida i stället för barriärens of pericytes for small-molecular drug transport across the blood-brain barrier a closer insight into different aspects of transport in a pericyte-deficient state.

Recent studies reveal that blood-brain barrier leaks occurring during Alzheimer’s are likely due to a loss of pericytes. Astrocytes, on the other hand, seem to be overactive as the body gets older. Scientists believe preserving pericyte function or transplanting new ones may restore the barrier to health. Pericytes: Specialized mesenchymal cells (mesodermal origin) associated with the walls of blood vessels including capillaries of the blood-brain barrier.

The stability of the BBB structure and function is of great significance for the maintenance of brain homeostasis. The brain pericyte–like cells induced blood-brain barrier properties in BMECs, including barrier enhancement and reduced transcytosis. Last, brain pericyte–like cells were incorporated with iPSC-derived BMECs, astrocytes, and neurons to form an isogenic human model that should prove useful for the study of the NVU.

The BBB’s unique ability to selectively permit transport of substances from the vascular supply to nervous system cells is critical to ensure brain homeostasis and prevent toxic injury to the constituent elements of the brain.

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 … The endothelial cells lining the capillaries supplying the brain with oxygen and nutrients form a formidable barrier known as the blood–brain barrier (BBB), which exhibits selective permeability to small drug molecules and virtually impermeable to macromolecular therapeutics.

Pericytes contribute to the regulation of blood–brain barrier permeability. The percentage of endothelial cell coverage by pericytes is inversely proportional to the permeability of the BBB. Pericytes regulate TJ formation and influence transendothelial vesicular transport [10] . Evidence from a variety of sources suggests that pericytes have contractile properties and may therefore function in the regulation of capillary blood flow. However, it has been suggested that contractility is not a ubiquitous function of pericytes, and that pericytes surrounding true capillaries apparently lack the machinery for contraction.
