Abstract

Nitric oxide synthase (NOS) immunoreactivity occurs in two groups of neurons in the guinea pig small intestine: descending interneurons that are also immunoreactive for choline acetyltransferase (ChAT), and inhibitory motor neurons that lack ChAT immunoreactivity. Interneurons that are involved in local reflexes would be expected to have inputs from intrinsic primary afferent (sensory) neurons, most of which are calbindin-immunoreactive. We examined this possibility using triple staining for NOS, ChAT and calbindin immunoreactivity and investigated the relationships between calbindin-immunoreactive varicosities and the cell bodies of NOS-immunoreactive neurons, using high-resolution confocal..
