title: Bradykinin stimulation of inositol phosphate and calcium responses in insensitive to pertussis toxin in NG115-401L neuronal cells.
abstract: Stimulation of NG115-401L neuronal cells with bradykinin produces a dose-dependent increase in inositol phosphate production which is not blocked, rather slightly increased, after treatment with pertussis toxin. Nevertheless, pertussis toxin stimulates ADP-ribosylation of a 41K membrane protein, and blocks opioid receptor-mediated inhibition of stimulated cAMP production in these cells. These results suggest that bradykinin responses in the NG115-401L cells are pertussis-insensitive, unlike bradykinin responses reported in other neuronal cell lines.
