dc.description.abstract | Acute lung injury (ALI) is a lung inflammatory disease for which pulmonary delivery of drug and genecould be a useful strategy. In this study, cholesterol-conjugated polyamidoamine (PAM-Chol) was synthesized and characterized as a carrier for combined delivery of anti-inflammatory gene and drug into the lungs by inhalation. The PAM-Chol formed self-assembled micelles in an aqueous solution with a critical micelle concentration of 0.22 mg ml−1. An in vitro transfection assay to L2 lung epithelial cells showed that the PAM-Chol micelle had higher transfection efficiency than lipofectamine and polyethylenimine (25 kDa, PEI25k). As the anti-inflammatory drug, resveratrol was loaded into the cores of the PAM-Chol micelles using the oil-in-water emulsion/solvent evaporation method. In lipopolysaccharide (LPS)-activated macrophage cells, resveratrol-loaded PAM-Chol (PAM-Chol/Res) and curcumin-loaded PAM-Chol (PAM-Chol/Cur) reduced pro-inflammatory cytokines, confirming the possibility of delivering hydrophobic drug by PAM-Chol. In in vitro transfection assays to L2 cells, the PAM-Chol/Res or PAM-Chol/Cur micelles had similar transfection efficiency to that of PAM-Chol. The delivery of resveratrol or curcumin with the heme oxygenase-1 gene (pHO-1) by inhalation was evaluated in an ALI animal model. Resveratrol and curcumin delivery using the PAM-Chol micelles inhibited the nuclear translocation of nuclear factor-κB (NF-κB) and reduced pro-inflammatory cytokines in the lungs. pHO-1 delivery using PAM-Chol induced HO-1 expression and reduced pro-inflammatory cytokines. However, the highest anti-inflammatory effects were obtained with combined delivery of pHO-1 and drug using the pHO-1/PAM-Chol/drug complex, as demonstrated in cytokine assays and immunohistochemical studies. Therefore, the PAM-Chol micelle is an efficient carrier of hydrophobic drug and pHO-1 into the lungs and could be useful for the treatment of ALI by inhalation. | - |
