    • The present invention relates to novel DNA vaccines, configured to induce a robust and sustained immune response, and methods of use thereof. DNA vaccines proposed herein are configured to achieve this immune response by fusing the extracellular domain of a viral fusion protein to selected antigens or antigen-binding polypeptides. After the expression and secretion of the viral fusion-antigen protein from the initially transfected cells, the natural ability of the viral fusion protein to fuse to cell membranes and actively enter cells will allow for passive delivery of the fused target epitopes into neighboring cells, thus inducing a more robust immune response. The presented method described herein allows for the use of this DNA vaccine against known antigens present in proteins produced by infectious agents or cancer cells within a subject, against unknown antigens produced by infectious agents or cancer cells within a subject, or against naturally-occurring or synthetically-derived antigens delivered by other routes, such as injection.
    • 本发明涉及新型DNA疫苗,其被配置为诱导稳健和持续的免疫应答,以及其使用方法。 通过将病毒融合蛋白的胞外结构域与选择的抗原或抗原结合多肽融合来配置本文提出的DNA疫苗以实现该免疫应答。 在从最初转染的细胞表达和分泌病毒融合抗原蛋白后,病毒融合蛋白融合到细胞膜并主动进入细胞的天然能力将允许被融合的靶表位被动递送到相邻细胞中,因此 诱导更强大的免疫应答。 本文所述的方法允许使用这种DNA疫苗针对存在于受试者体内的感染因子或癌细胞产生的蛋白质中的已知抗原,针对受试者体内的感染因子或癌细胞产生的未知抗原,或针对天然存在的或 通过其他途径(如注射)递送的合成衍生抗原。
