Release-depletion and receptor-mediated neuronal internalization of endogenous neurotensin in the stellate ganglion of the cat.


The release and depletion of neurotensin in sympathetic preganglionic axon terminals and internalization in principal ganglion cells were investigated in the cat stellate ganglion by means of combined immunohistochemical staining, image analysis and confocal microscopy. Neurotensin stored in preganglionic boutons was released by 40 or 5 Hz electrical… (More)
