NANOPARTICULES, LEUR PROCÉDÉ DE PRÉPARATION ET LEUR UTILISATION EN TANT QU'EXCIPIENT POUR DES MOLÉCULES HYDROPHOBES AMPHIPATHIQUES DANS DES DOMAINES DE LA MÉDECINE, NOTAMMENT DANS LE TRAITEMENT DU CANCER ET DES ALIMENTS COMPOSÉS ASSOCIÉS
The present invention regards nanoparticles comprising a sterol and a component derived from Quillaja saponaria Molina selected from quillaja acid and quillaja saponin, which nanoparticles do not comprise a phospholipid. It also relates to a composition comprising the nanoparticles, and the use thereof as adjuvant, especially in vaccines, as carriers for amphipathic or hydrophobic molecules and as agents for treatment of cancer. Further, it regards a method for producing the phospholipid-free nanoparticles, a method for the treatment of cancer and a method for assessing the applicability of the cancer treating method.
