Abstract
Most neurons in the central nervous system and peripheral nervous system do not express water transporting protein, aquaporin (AQP). In the present study, we have demonstrated the presence of AQP1 immunoreactivity in a particular neuronal subtype in the enteric nervous system (ENS) of the rat ileum. AQP1-immunoreactive (IR) neurons simultaneously expressed a neuronal marker HuC/D. Moderate numbers of AQP1-IR neuronal somata were found in the myenteric plexus, and a very few were found in the submucosal plexus. AQP1-IR neurons can be classified as Dogiel type I cells, which have several short processes and a single long process. Many AQP1-IR fibers were found both in the myenteric and submucosal plexi. Many AQP1-IR varicose fibers were closely associated with neuronal somata in the ganglia, whereas other AQP1-IR fibers penetrated into the muscle layers. These results suggest that AQP1-IR neurons probably play a significant role within the ENS to control gut functions.
