L'élévation de la concentration calcique cytoplasmique est un élément central de la signalisation cellulaire. L'entrée de calcium du milieu extérieur dans le cytosol est un processus essentiel qui assure la pérennité des signaux calciques en permettant le remplissage des stocks calciques intracellulaires situés principalement dans le réticulum endoplasmique (RE). Dans les cellules non excitables, deux différents types d'influx prédominent, l'un activé par la vidange du RE le SOCE (Store-Operated Ca2+ Entry) l'autre activé par des seconds messagers indépendamment du remplissage des stocks calciques le RACE (Receptor-Activated Ca2+ Entry). Dans un premier temps nous avons étudié le processus de remplissage du RE qui accompagne l'influx SOCE a...
