our results indicate that the preprotachykinin gene encoding the tachykinin peptides , substance p and neurokinin a , is transcribed in a population of enteric neurons that have a regional distribution comparable to the previously described tachykinin-like immunoreactive neurons , suggesting that specific mrnas and the posttranslationally processed peptides are localized in the same structures .
