junctional complex

junc·tion·al com·plex

the attachment zone between epithelial cells, typically consisting of the zonula occludens, the zonula adherens, and the macula adherens (desmosome).

Caption: Figure 2: Cx channels form the intercellular junctional complex. TJ contains a complex of proteins spanning the intercellular cleft (occludin and claudin).
Apolar tissue: cells with polarities of any orientation, without apical belt-shaped junctional complexes, being submerged in the extracellular matrix (Rieger, 1986).
Dismantling of the apical junctional complex during EMT is necessary for epithelial cells to detach from one another and migrate away as individuals (Boyer et al., 2000).
At higher magnification, the plasma membrane of these cells possessed abundant microvillar projections with junctional complexes joining adjacent cells (Figure 4(d)).
The basal plasmalemma showed tight junctional complexes with adjacent cell membrane and in certain areas distinct intercellular canaliculi were present between the cells.
Furthermore, the mechanisms that affect adhesion molecules and junctional complexes and their significance in primary sclerosing cholangitis and extrahepatic cholestasis are elucidated.
With his collaborators, Palade described a transport system across the endothelium and identified the so-called Weibel-Palade bodies which play a role in coagulation and inflammation; he also described the neuronal synapses, the tight junctions and junctional complexes in glomerular cells and the secretory pathways of proteins from the endoplasmic reticulum towards the extracellular compartment.
The instrument will be used to measure parameters of cell monolayer formation and extent of cell contact through junctional complexes. The detection of these events and being able to distinguish between then can be achieved by impedance measures at different AC frequencies.
The junctional complexes between follicular cells in the apico-lateral borders were quite distinct with a prominent tight jun ction from which single cilium sometimes projected from it into the luminal colloid (Fig.1D).
Several junctional complexes, including adherens junctions and tight junctions, participate in this process [6].
