Using the technology of Sleeping Beauty transposons for genetic engineering and cell-mediated immunity

Sustainable production of transgenes in human cells can be combined of both viral and non-viral methods for gene therapy. Efficient transfection into primary cells is proposed by recombinant virus technology; even though provided by reports of successful treatment, it still has a lot of disadvantages. As of today, the use of plasmids can be a viable alternative to viral vectors for its reduced costs, low immunogenicity, and effective insertion. In the past decades, Sleeping Beauty transposons (SB) have been developed as a non-viral vector system for gene therapy, with the shared benefits of both vectors and naked DNA. The SB system has been successfully used in human T cells for generating specific chimeric antigen receptors (CAR). This article is aimed to introduce transposon technology for a safe genetransfer into human cells with the emphasis on SB systems. Moreover, viral and non-viral gene transfer systems are described by considering both the advantages and disadvantages.
