Paracellular transport
From Wikipedia, the free encyclopedia
Paracellular transport refers to the transfer of substances between cells of an epithelium.[1][2]
It is in contrast to "transcellular transport", where the substancees travel through the cell, passing through both the apical membrane and basolateral membrane.[3][4][5]
The distinction is in particular significance in renal physiology. Transcellular transport is more likley to involve energy expenditure than paracellular transport.[6]
In paracellular transport, the substances usually travel through tight junctions.
