제목 Gene Delivery of PAMAM Dendrimer Conjugated with KRTR peptides originated from Influenza B Virus Nucleoprotein
초록 The polyamidoamine (PAMAM) dendrimer is one of the cationic polymers that are widely used in nonviral gene therapy research, and PAMAM shows a sufficient biocompatibility and relatively low cytotoxicity. it has poor transfection efficiency In comparison to polyethylenimine (PEI, 25 kDa). To improve transfection efficiency, we introduced the KRTR peptide derived from influenza B virus nucleoprotein into PAMAM. We synthesized PAMAM-RTRK and PAMAM-HRTRK to determine the difference in their cytotoxicity. PAMAM-RTRK and PAMAM-HRTRK showed a transfection efficiency that corresponded to that of PEI in HepG2 and A549 cell lines. These results imply that the combination of histidine with the KRTR peptide could potentially provide a novel PAMAM-based vector that could be used prolonged gene therapy by reducing cytotoxicity and enhancing gene expression.
