Abstract

Autonomic sympathetic postganglionic neurons normally express distinct combinations of neuropeptides which are often highly correlated with the projection of the neurons. When sympathetic postganglionic neurons are axotomized, they can express quite different neuropeptides, notably substance P, vasoactive intestinal peptide or galanin. In this study, we have examined rat sympathetic postganglionic neurons in the superior cervical ganglion that project to the skin, the vasculature of the skeletal muscle or to the submandibular salivary gland, and assessed whether the neuropeptides that they express after axotomy depend on which target tissue they previously innervated. In all three population..
