Résumé: La contraction du muscle excitable, comme le muscle cardiaque et le muscle lisse vasculaire, dépend surtout de l'entrée du Ca2+ à l'intérieur de la cellule (ou la libération du [Ca]i) via des canaux voltages dépendants (de type T ou L) ou des canaux opérés par récepteurs. Le but de cette étude est de vérifier si certaines hormones comme l'insuline, l'endotheline-1 et la bradykinine augmentent le [Ca]i des cellules cardiaques et vasculaires via la stimulation des canaux calciques par un mécanisme qui est indépendant de l'activation des récepteurs. De plus, on a étudié les effets d'un agent pharmacologique, le BRL 34915, un ouvreur des canaux KATP afin de vérifier l'hypothèse que certains canaux Ca2+ dépendants du voltage peuvent être...
