Abstract

Cette invention a trait à des conjugats polymère-lipide-cationique (CPL) tel que des conjugats poly(éthylène glycol)-lipide-cationique distaux pouvant être incorporés à des liposomes classiques ou à des liposomes furtifs ou à toute autre formulation à base de lipide pour renforcer l'absorption cellulaire. Les CPL selon l'invention comportent une fraction lipidique, un polymère hydrophile et une fraction polycationique. L'invention concerne également une méthode permettant de renforcer la libération intracellulaire d'acides nucléiques.
