Infectious large capacity vectors for gene therapy [ 2003 - 2005 ]

Research Grant

Researchers: Dr Michael James (Principal investigator)

Brief description The next 25 to 50 years will witness the culmination of a demographic shift in the age of the population which will be associated with an increasing importance of both inherited predispositions to late-onset chronic, complex diseases and natural degenerative processes. Medicine has historically sought to manage and cure the symptoms of disease. The focus for therapy has begun to switch from alleviating the ailments to establishing and resolving their causes. On the back of the Human Genome Project, genetics research will identify genes that are central to these processes, leading to gene-based medicine. Some of this new treatment will be drug-based but an alternative is the correction of the defective genes themselves gene therapy to either replace inherited faulty genes or to provide novel or modified genes that may help the repair and maintenance of tissue, or combat abnormal processes such as cancer. Gene therapy is a field still in its infancy with just a few qualified successes reported in the past few years. Persistent expression of a transgene at therapeutic levels is required for successful gene therapy. Most of the currently used vector and virus systems have a small capacity and usually employ a reduced (cDNA) copy of the transgene lacking natural control mechanisms. These are prone to vector loss and promiscuous expression or loss of expression. The delivery of genomic DNA up to 20 times this size would enable genes to be transferred in entirety, including their natural regulatory elements. This project aims to develop a vector system based on Herpesviruses that tackles some of the problems with the current generation of gene therapy vectors. This system is particularly aimed at providing long-term gene expresssion at physiological levels and safe, efficient delivery systems through the use of genomic DNA.
