Tight junctions are one mode of cell–cell adhesion in epithelial and endothelial cellular
sheets. They act as a primary barrier to the diffusion of solutes through the intercellular …

The choroid plexus epithelium is a cuboidal cell monolayer, which produces the majority of
the cerebrospinal fluid. The concerted action of a variety of integral membrane proteins …

The adult brain functions within a well-controlled stable environment, the properties of which
are determined by cellular exchange mechanisms superimposed on the diffusion restraint …

There are two strains of MDCK cells, MDCK I and II. MDCK I cells show much higher
transepithelial electric resistance (TER) than MDCK II cells, although they bear similar …

An epithelial cell line (MDCK) was used to prepare monolayers which, in vitro, develop
properties of transporting epithelia. Monolayers were formed by plating cells at high …

We present and discuss the role of endothelial and astroglial cells in managing the blood-
brain barrier (BBB) and aspects of pathological alterations in the BBB. The impact of …

The urothelium, which lines the renal pelvis, ureters, urinary bladder, and proximal urethra,
forms a high-resistance but adaptable barrier that surveils its mechanochemical …

Careful examination of relevant literature shows that many of the most cherished concepts of
the blood-brain barrier are incorrect. These include an almost mythological belief in its …

Electrical circuit analysis was used to study the structural development of occluding
junctions (OJs) in cultured monolayers composed to T84 cells. The magnitude of the …

Mammalian choroid plexuses develop at four sites in the roof of the neural tube shortly after
its closure, in the order IVth, lateral, and IIIrd ventricles. Bone morphogenetic proteins and …
