摘要：

The présent invention relates to cell-penetrating peptides char-acterized in that it comprises an amino acid séquence selected in the group consisting of X1LX2RALWX9LX3X9X4LWX9LX5X6X7X8, X1LX2LARWX9LX3X9X4LWX9LX5X6X7X8 and X1LX2ARLWX9LX3X9X4LWX9LX5X6X7X8, wherein X1 is beta-A or S, X2 is F or W, X3 is L, W, C or I, X4 is S, A, N or T, Xs is L or W, X6 is W or R, X7 is K or R, X8 is A or none, and X9 is R or S. Thèse peptides exhibit high efficiency, low toxicity and a natural tropism for lung tissues, and can be used either in simple complex with the cargo to be vectorised, or in nanoparticles comprising two layers of cell-penetrating peptides around the cargo.
