Localization of substance P-like immunoreactivity in cell bodies of the feline dorsal vagal nucleus.
Using the peroxidase-antiperoxidase (PAP) technique, substance P-like immunoreactivity (SPLI) was localized in the dorsal vagal nucleus as punctate varicosities in non-treated cats. In animals treated with colchicine 48 h prior to sacrifice, SPLI varicosities as well as significant numbers of cell bodies found throughout the entire extent of the dorsal vagal nucleus. Results of this study not only confirm the presence of SPLI in the dorsal vagal nucleus but also suggest a possible additional source of SPLI which has been reported to be present in the vagus nerve.
