Objective(s): Interleukin-36 receptor antagonist (IL-36Ra) is a new member of the IL-1 family that exhibits anti-inflammatory activity in a variety of inflammatory and immune diseases. Our purpose was to determine the effect of IL-36Ra on liver injury in a mouse hepatitis model induced by concanavalin A (ConA). Materials and Methods: Mic...

objective(s): pei based nanoparticle (np) due to dual capabilities of proton sponge and dna binding is known as powerful tool for nucleic acid delivery to cells. however, serious cytotoxicity and complicated conditions, which govern nps properties and its interactions with cells practically, hindered achievement to high transfection efficiency. here, we have tried to optimize the properties of ...

Sustained gene delivery of interferon (IFN) γ can be an effective treatment, but our previous study showed high levels of IFNγ-induced adverse events, including the loss of body weight. These unwanted events could be reduced by target-specific delivery of IFNγ after in vivo gene transfer. To achieve this, we selected the heparin-binding domain (HBD) of extracellular superoxide dismutase as a mo...

chitosan-graft-polyethylenimine (chi-g-pei) copolymer has been used for theimprovement of low transfection efficiency of chitosan. the present study aims to test thepulmonary toxicity and efficiency of chi-g-pei as an aerosol gene carrier. mice were exposedto aerosol containing green-fluorescent protein (gfp)-polyethylenimine (pei) or gfp-chig-pei complexes for 30 min during the development of ...

A new siRNA delivery system using a cationic glyco-star polymer is described. Spermine-modified 8-arm amylose star polymer (with a degree of polymerization of approximately 60 per arm) was synthesized by chemoenzymatic methods. The cationic star polymer effectively bound to siRNA and formed spherical complexes with an average hydrodynamic diameter of 230 nm. The cationic 8-arm star polymer comp...

Hydrodynamic gene delivery has proven to be a safe and efficient procedure for gene transfer, able to mediate, in murine model, therapeutic levels of proteins encoded by the transfected gene. In different disease models and targeting distinct organs, it has been demonstrated to revert the pathologic symptoms and signs. The therapeutic potential of hydrofection led different groups to work on th...

Non-viral gene therapy offers the potential to deliver nucleic acids producing therapeutic proteins to treat genetic diseases without the limitations observed with viral vectors. Before the therapeutic potential of non-viral gene delivery can be realized, several barriers to efficient gene delivery must be overcome. One delivery barrier of interest is the enhancement of endosomal escape to prev...

One of the major research focuses in the field of gene therapy is the development of clinically applicable, safe, and effective gene-delivery methods. Since the first case of human gene therapy was performed in 1990, a number of gene-delivery methods have been developed, evaluated for efficacy and safety, and modified for human application. To date, viral-vector-mediated deliveries have shown e...
