Uses of viral vectors have thus far eclipsed uses of non-viral vectors for gene therapy delivery in the clinic. Viral vectors, however, have certain issues involving genome integration, the inability to be delivered repeatedly, and possible host rejection. Fortunately, development of non-viral DNA vectors has progressed steadily, especially in plasmid vector length reduction, now allowing these...
Recent advances in designing safe and efficient viral vectors have spearheaded unprecedented growth clinical trials regulatory approvals for experimental gene therapies. Still, important challenges remain therapies that require systemic administration into the circulation, including patient’s immune response need precise activation target cell population while sparing other tissues. Extensive r...
Objective: Transient expression of therapeutic genes within lung allografts may modulate the pathological processes following allotransplantation. Whilst ef®cient gene transfer to lungs has been reported with viral vectors, their usefulness is limited on the grounds of safety. Since non-viral systems overcome many of these safety issues, our studies were designed to evaluate the ef®ciency of se...
The Sleeping Beauty (SB) transposon system is a non-viral gene delivery platform that combines simplicity, inexpensive manufacture, and favorable safety features in the context of human applications. However, efficient correction of hematopoietic stem and progenitor cells (HSPCs) with non-viral vector systems, including SB, demands further refinement of gene delivery techniques. We set out to i...
Therapeutic approaches using gene-based medicines promise alternatives or adjuncts to conventional cancer treatment. Because of its non-invasive nature, ultrasound, as a membrane-permeabilising stimulus has the potential to be highly competitive with viral gene delivery and existing non-viral alternatives. In optimising ultrasound-mediated, microbubble-assisted (MB101) gene tranfection in vitro...
background type 1 diabetes mellitus is one of the metabolic diseases that cause insulin-producing pancreatic ß cells be destroyed by immune system self-reactive t cells. recently, new treatment methods have been developed including use of the stem cells, ß islet cells transplantation and gene therapy by viral and non-viral gene constructs. objectives the aim of this project was preparing the n...
Infectious Pancreatic Necrosis Virus (IPNV) is a member of the family Birnaviridae that has been linked to high mortalities in salmonids. Bacterial based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. VP2 is a structural viral protein of IPNV with immunogenicity effects. In this study IPNV was isolated from diseased fry ...
Sleeping Beauty (SB) is the first synthetic DNA transposon that was shown to be active in a wide variety of species. Here, we review studies from the last two decades addressing both basic biology and applications of this transposon. We discuss how host-transposon interaction modulates transposition at different steps of the transposition reaction. We also discuss how the transposon was transla...

A major obstacle in applying gene therapy to clinical practice is the lack of efficient and safe gene delivery techniques. Viral delivery has encountered a number of serious problems including immunological reactions and malignancy. Non-viral delivery methods (liposomes, sonoporation and electroporation) have either low efficiency invivo or produce severe collateral damage to ocular tissues. We...
