The Difference of Aquaporin 5 Distribution in Acinar and Ductal Cells in Lacrimal and Parotid Glands

Abstract

AQP5 distribution in acinar cells and ductal cells was completely opposite in the lacrimal and parotid glands. The physiological role of AQP5 might be dependent on the characteristic tissue distribution of the protein in the lacrimal and parotid glands.
