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.

Tight junctions are a type of cell-cell junction found in epithelia that forms a barrier that is impermeable to the majority of soluble molecules between the two sides of the epithelium.

The mechanisms that cause these symptoms are not fully understood. The stress of heat and oxidative damage during exercise causes disruption to intestinal epithelial cell tight junction proteins ...

A 3D model accurately mimicking the blood-brain barrier (BBB) in a laboratory environment has been successfully developed by ...
