Thèmes de recherche

Expression et fonctionnalité de canaux ioniques (canaux sodiques NaV et récepteurs purinergiques P2X) dans des cellules cancéreuses d'origine épithéliale (cellules mammaires). Rôles dans les phénomènes de migration et d'invasivité. Régulation de ces canaux par des acides gras polyinsaturés à longue chaîne d'origine alimentaire.
