Diffusion is a type of passive transport in which molecules move from an area of high concentration to low concentration. Diffusion occurs along the concentration gradient, or the gradual difference in the concentration of substances between two areas. Facilitated diffusion is how molecules move down ...

[7]. These cells tightly bind together to prevent paracellular drug transport across the BBB and contribute to the high transendothelial resistance (TEER) that limits the passive diffusion of external compounds between the brain and blood [8,9]. Both pericytes and astrocytes play a supporting role...
