Abstract

Calretinin immunoreactivity was present in a subset of preganglionic neurons retrogradely labelled from the cat adrenal gland. Overall, one-third of adrenal preganglionic neurons showed calretinin immunoreactivity, and their proportion increased in the more caudal spinal cord segments. Calretinin-immunoreactive nerve terminals were prominent within the adrenal gland, but were found only in areas of noradrenergic chromaffin cells (approximately one-third of the area of the adrenal medulla). Synaptophysin immunoreactivity was used to label terminals with and without calretinin immunoreactivity. Nerve terminals lacking calretinin immunoreactivity were present among the adrenergic chromaffin-cel..
