CpG methylation of a plasmid vector results in extended transgene product expression by circumventing induction of immune responses.
Gene therapy has the potential to cure inherited diseases if the delivered genes achieve long-term expression at therapeutic levels in the targeted tissues. Expression is commonly short-lived due to induction of cell-mediated immune responses to the gene therapy vehicle and/or the transgene product, which can be perceived as "foreign" by the host's immune system. Plasmid expression vectors have been used to deliver genes. Bacterial DNA carries immunostimulatory sequences in the form of unmeth...Expand abstract
