...) lysosomal degradation proteolytic release transcytosis Epithelial cells form a tight monolayer of cells that line the internal surfaces of our organs and the external surfaces of our bodies. Many of these are specialized for absorption and secretion. The entire organization of the epithelium...

... domain. Physical association of GG-pIgR with pIgA in bile and intestine demonstrates that this protein is a functional receptor. Thus, as shown for mammals, this receptor interacts with J-chain-containing polymeric IgA (pIgA) at the basolateral epithelial cell surface resulting in transcytosis...

Michael DANIELSEN The brush border of small intestinal enterocytes is highly enriched in cholesterol- and glycosphingolipid-containing membrane microdomains, commonly termed as lipid ‘rafts’. Functionally, transcytosis...
