NOUVEAUX LIPOSOMES DE VACCINATION GENIQUE

摘要

The present invention relates to liposomes composed of DOPE and/or of a variant of DOPE bearing at least one ligand for targeting dendritic cells, of DOTAP and/or of a variant of DOTAP bearing at least one ligand for targeting dendritic cells and of cardiolipin and/or of a variant of cardiolipin bearing at least one ligand for targeting dendritic cells; and to the use thereof as a genetic material carrier for preparing lipoplexes. The lipoplexes according to the invention are advantageous because of the limited cytotoxicity thereof in vivo; they are therefore of particular interest for gene vaccination; in a form encapsulated in a biodegradable and nonimmunogenic cell such as an alginate gel, they are particularly suitable in particular for oral vaccination of aquatic animals.
