Shuttle-mediated transcytosis
Did you know?
Transcytosis can be receptor-mediated and consists of three steps: 1) receptor-mediated endocytosis of the molecule on one side of the cell, e.g. the luminal side; 2) movement of the molecule through the intracellular compartment typically within the endosomal system; and 3) exocytosis of the molecule to the … See more Transcytosis (also known as cytopempsis) is a type of transcellular transport in which various macromolecules are transported across the interior of a cell.
