1. The blood-brain barrier is essential for the maintenance and regulation of the neural microenvironment. The main characteristic features of blood-brain barrier endothelial cells are an extremely low rate of transcytotic vesicles and a restrictive paracellular diffusion barrier. 2. Endothelial blood-brain barrier tight junctions differ from epithelial tight junctions, not only by distinct mor...
Tight junction, one of the type of cell-cell junctions, controls the paracellular permeability across the lateral intercellular space and maintains the cell polarity. Tight junctions consist of transmembrane proteins: members of tight junction-associated MARVEL protein (TAMP) family, claudins and junctional adhesion molecules (JAMs), and various cytoplasmic proteins that are necessary for the c...
The mammalian protein ASIP/PAR-3 interacts with atypical protein kinase C isotypes (aPKC) and shows overall sequence similarity to the invertebrate proteins C. elegans PAR-3 and Drosophila Bazooka, which are crucial for the establishment of polarity in various cells. The physical interaction between ASIP/PAR-3 and aPKC is also conserved in C. elegans PAR-3 and PKC-3 and in Drosophila Bazooka an...
ERK (extracellular-signal-regulated kinase) activation leads to disruption of tight junctions in some epithelial monolayers, whereas it prevents disruption of tight junctions in other epithelia. The factors responsible for such contrasting influences of ERK on tight junction integrity are unknown. The present study investigated the effect of the state of cell differentiation on ERK-mediated reg...
