title: Immunocytochemical localization of ACTH perikarya in nucleus tractus solitarius: evidence for a second opiocortin neuronal system.
abstract: Immunocytochemical localization of ACTH-opiocortin perikarya was demonstrated in the medulla of colchicine-treated rat. Neuronal cell bodies and fibers containing ACTH-immunoreactivity were abundant in the caudal region of the nucleus tractus solitarius, specifically within pars commisuralis. Location of these opiocortin neurons within the nucleus tractus solitarius provides additional evidence for a role of these peptides in cardiovascular functions.
