Gene delivery remains to be a very challenging field to efficiently transport the therapeutic gene and to modulate proteins with the desired function at the target site. The physiochemical and biological barriers are the major hurdles that need to be considered, particularly when administered systematically, in order to optimize the therapeutic efficacy. Numerous modifications have been extensively investigated aiming to provide protection from the plasma degradation, enhancement of transfection, target specificity, and most importantly, minimizing the side effects such as cellular toxicity and immune response. This article provides a review with respect to the in vitro and in vivo toxicity, as well as cellular and physiological interactions with the gene delivery system composed from viral vectors, cationic lipids and polymers. Recent progress and development are also addressed, with promising results that may be further adopted for clinical use.

More about this publication?
  • Current Drug Metabolism aims to cover all the latest and outstanding developments in drug metabolism and disposition. The journal serves as an international forum for the publication of timely reviews in drug metabolism. Current Drug Metabolism is an essential journal for academic, clinical, government and pharmaceutical scientists who wish to be kept informed and up-to-date with the latest and most important developments. The journal covers the following areas:

    In vitro systems including CYP-450; enzyme induction and inhibition; drug-drug interactions and enzyme kinetics; pharmacokinetics, toxicokinetics, species scaling and extrapolations; P-glycoprotein and transport carriers; target organ toxicity and interindividual variability; drug metabolism and disposition studies; extrahepatic metabolism; phase I and phase II metabolism; recent developments for the identification of drug metabolites and adducts.
