Metabolism and Transport of Purinergic Receptor Agonists in Rabbit Conjunctival Epithelial Cells

The role of extracellular nucleotides as signaling molecules is well established in a number of biological systems. Their function in the regulation of ion1, 2 and fluid3 transport has been investigated in the pigmented rabbit conjunctiva where active Cl− secretion has been implicated as the driving force for fluid secretion.3 These agonists interact with two classes of receptors located on the cell membrane: P2X ligand-gated ion channels and P2Y G-protein-coupled receptors.4 Receptor mapping techniques have revealed the presence of P2Y type receptors in ocular epithelial cells.5
