英文摘要
Novel charge-invertible nanoparticles were developed that can respond to the acidic pH of a tumor. We designed a unique peptide(referred to as a slightly acidic pH sensitive peptide : SAPSP), as a pH responsive device for intelligent nanoparticles consisting of cationic liposomes. The cellular uptake of SAPSP-modified liposomes(SAPSP-lipo) increased at tumoral pH(pH 6. 5) due to conversion of the liposomal surface charge from negative to positive. In addition, siRNA-encapsulated SAPSP-lipo induced a significant knock down effect, but only at pH 6. 5. These results indicate that SAPSP-lipo represents a novel intelligent drug delivery system that can respond to tumoral pH for use in cancer therapy.
