Delivery of therapeutic agents via intratracheal administration is an attractive strategy for the treatment and prevention of aerodigestive tract cancers, as well as the prevention of ischemia-reperfusion injury and acute rejection following lung transplantation. Relative to viral delivery systems, naked plasmid vectors are markedly less efficient with regard to gene transfer to respiratory epithelia. However, plasmid vectors are easier and less costly to produce in large quantity, and are significantly less immunogenic than viral vectors; hence naked plasmid vectors may be utilized for repeated administration. Although presently not applicable for gene therapy of pulmonary neoplasms, naked plasma vectors expressing cytokines which function by paracrine mechanisms may be effective in attenuating the inflammatory processes associated with ischemia-reperfusion, or allograft rejection . . .
