Folate PEGylated archaeal lipids: cell targeting and drug delivery.

International audienceArchaeosomes are of interest for potential biotechnological applications such as biomaterial delivery. Indeed, the archaeal lipid analogues improve the stability of delivery systems, including oral administration [1,2]. We developed new archaeal lipid analogues equipped with cell targeting ligands such as folic acid (FA) [3]. In vitro transfection efficiencies of formulations including these lipids were evaluated on several cell lines, and have shown good efficiencies at neutral charge ratios and a clear ligand mediated cell internalisation
