We report on the development of a multifunctional envelope-type nano device (MEND) based on our packaging concept "Programmed packaging" to control not only intracellular trafficking but also the biodistribution of encapsulated compounds such as nucleic acids/proteins/peptides. Our strategy for achieving this is based on molecular mechanisms of cell biology such as endocytosis, vesicular traffi...
The ability to express transgenes selectively within the lung will greatly facilitate the development of gene therapy for a variety of human diseases. We have demonstrated that aerosol administration of a chloramphenicol acetyltransferase (CAT) expression plasmid complexed to cationic liposomes produces high-level, lung-specific CAT gene expression in mice in vivo. Significant levels of CAT act...
Extracellular vesicles (EVs) are the substances that conveyed by most sorts of cell, which play a critical role in cell-to-cell communication. Exosomes among commonly explored EVs. contain lipids, RNAs and proteins. Many examinations have shown exosomes derived from cells different biological roles normal as well diseased condition. Recent investigations natural drug delivery vehicles, they abi...
Objective(s): Polyethylenimine (PEI) is one of the most widely used polymers in gene delivery. The aim of this study was to modify PEI by replacing some of its primary amines with Brevinin 2R (BR-2R) peptide in order to increase the efficiency of gene delivery.Materials and Methods: Polyethylenimine was modified by BR-2R peptide by two d...
Gene delivery is a promising technique that involves in vitro or in vivo introduction of exogenous genes into cells for experimental and therapeutic purposes. Successful gene delivery depends on the development of effective and safe delivery vectors. Two main delivery systems, viral and non-viral gene carriers, are currently deployed for gene therapy. While most current gene therapy clinical tr...
Development of an effective, safe, and convenient method for gene delivery to the pancreas is a critical step toward gene therapy for pancreatic diseases. Therefore, we tested the possibility of applying the principle of hydrodynamic gene delivery for successful gene transfer to pancreas using rats as a model. The established procedure involves the insertion of a catheter into the superior mese...
Gene expression within a cell population can be directly altered through gene delivery approaches. Traditionally for nonviral delivery, plasmids or siRNA molecules, encoding or targeting the gene of interest, are packaged within nanoparticles. These nanoparticles are then delivered to the media surrounding cells seeded onto tissue culture plastic; this technique is termed bolus delivery. Althou...
