Tight junctions (blue dots) between cells are connected areas of the plasma membrane that stitch cells together. Adherens junctions (red dots) join the actin filaments of neighboring cells together.

The outermost layer of our organs achieves this with specialized seals between the cells known as tight junctions. Tight junctions are much like a joint between floor or wall tiles. They are belts ...

The lateral surfaces of epithelial cells also contain several other types of specialized junctions. Tight junctions form a seal between cells that is so strong that not even ions can pass across it.

Tight junctions regulate the passage of molecules ... of the cytoskeleton—in the organization of junctions between cells, and discovered that in its absence another form of actin, beta-actin ...

Scientists have identified tricellulin loss as the root cause of dry mouth in Sjögren's syndrome, and successfully reversed ...

A further barrier to nasal delivery is the existence of tight junctions between epithelial cells in the mucous membranes inside the nose, which can prevent the penetration of large molecules such as ...
