Cholinergic Neurotransmission in the Mammalian Retina.
Abstract
The cholinergic cells in the retina consist of matching subpopulations of amacrine and displaced amacrine cells which ramify narrowly in the inner plexiform layer (IPL). Previous cytochemical studies revealed that the hydrolytic enzyme acetylcholinesterase (AChE), which terminates the action of acetylcholine (ACh), is more widespread in its distribution than the enzyme choline acetyltransferase (ChAT), which is responsible for ACh synthesis. Cytochemical techniques were utilized to further define the sites of cholinergic interaction in the retina. Autoradiographic studies showed that both the muscarinic receptor ligand (3H)propylbenzilyl choline mustard and the putative nicotinic receptor ligand (3H)alpha-bungarotoxin bind preferentially in the IPL.
