Localization of NADPH oxidase in sympathetic and sensory ganglion neurons and perivascular nerve fibers
Abstract: Superoxide anion (O2−•) production was previously reported to be increased in celiac ganglia (CG) during DOCA–salt hypertension, possibly via activation of the reduced nicotinamide-adenine dinucleotide phosphate (NADPH) oxidase. This suggested a role for neuronal NADPH oxidase in autonomic neurovascular control. However, the expression and localization of NADPH oxidase in the peripheral neurons are not fully known. The purpose of this study was to examine the subcellular localization of NADPH oxidase in sympathetic and sensory ganglion neurons and perivascular nerve fibers. In rat CG, p22phox and neuropeptide Y (NPY) were colocalized in all neurons. P22phox was also localized to dorsal root ganglia (DRG) neurons that contain calcitonin gene related peptide (CGRP).
