The application of gene therapy in autoimmune diseases

The application of gene therapy in autoimmune disease represents a novel use of this technology. The goal of gene therapy in the treatment of autoimmune disease is to restore 'immune homeostasis' by countering the pro-inflammatory effects of the CD4+ T cells in the lesions of autoimmunity. This can be accomplished by adoptive therapy with transduced T cells which can specifically home to the site of inflammation and secrete 'regulatory' protein(s) to ameliorate the inflammation or by direct targeting of the retroviral vector to activated T cells in the sites of inflammation. Transduction of autoantigen recognizing CD4+ T cells, to secrete anti-inflammatory products, may become the 'magic bullet' to combat the ravages of autoimmune inflammation and tissue destruction.
