Substance P receptor-mediated secretion of respiratory glycoconjugate from feline airways in vitro.


The effect of substance P (SP) and other tachykinins on respiratory glycoconjugate (RGC) release was studied in a feline tracheal organ culture system. SP in concentrations of 10(-5) and 10(-6) M stimulated an increase in RGC release of 35 +/- 8% and 18.5 +/- 5%, respectively. The addition of the protease inhibitor aprotinin or the enkephalinase inhibitor… (More)
