Targeted Gene Delivery by Intravenous Injection of Retroviral Vectors

Targeted synthetic gene delivery vectors.

Synthetic gene delivery vehicles have made significant progress in the past decade in demonstrating strong potential for targeted delivery to specific cells, low toxicity and immunogenicity and large carrying capacity. However, significant advances must still be made to increase the efficiency of both polymer and lipid vehicles. Furthermore, techniques to generate more effective targeting moiet...

Enhanced gene transfer activity of peptide-targeted gene-delivery vectors.

We have evaluated the capacity of the cell-binding heptapeptide SIGYPLP to enhance transgene expression using non-viral and viral gene delivery vectors. Targeted polyplex based vectors showed good levels of DNA uptake in freshly isolated human umbilical vein endothelial cells (HUVECs) compared to untargeted controls, whilst displaying only modest increases in reporter gene activity. The targete...

Tropism-Modification Strategies for Targeted Gene Delivery Using Adenoviral Vectors

Achieving high efficiency, targeted gene delivery with adenoviral vectors is a long-standing goal in the field of clinical gene therapy. To achieve this, platform vectors must combine efficient retargeting strategies with detargeting modifications to ablate native receptor binding (i.e. CAR/integrins/heparan sulfate proteoglycans) and "bridging" interactions. "Bridging" interactions refer to co...

Gene Delivery to Adipose Tissue Using Transcriptionally Targeted rAAV8 Vectors

In recent years, the increasing prevalence of obesity and obesity-related co-morbidities fostered intensive research in the field of adipose tissue biology. To further unravel molecular mechanisms of adipose tissue function, genetic tools enabling functional studies in vitro and in vivo are essential. While the use of transgenic animals is well established, attempts using viral and non-viral ve...
