title: [Recent advances in DNA vaccines against allergic airway disease: a review].
abstract: DNA vaccine is used in infectious diseases initially, and later is applied in neoplastic diseases, allergic diseases and other fields with the further understanding of DNA vaccine and the development of genetic engineering. DNA vaccine transfers the genes encoding exogenous antigens to plasmid vector and then is introduced into organism. It controls the antigen proteins synthesis, thus induces specific humoral and cellular immune responses. So it has a broad application prospect in allergic diseases. Compared with the traditional protein vaccines used in specific immunotherapy, DNA vaccine has many advantages, including high purity and specificity, and improvement of patients' compliance etc. However, there are still two unsolved problems. First, the transfection rate of unmodified naked DNA plasmid is not high, Second, it's difficult to induce ideal immune response. In this study, we will review the progress of DNA vaccine applications in respiratory allergic diseases and its various optimization strategies.
