    • Methods of inducing an immune response against an immunogen in an individual are disclosed. The methods comprise administering to the individual, one or more nucleic acid molecules that comprise a nucleotide sequence that encodes an immunogen and a nucleotide sequence that encodes an Major Histocompatibility Complex antigen. The nucleotide sequences that encode the immunogen and the Major Histocompatibility Complex antigen are expressed when taken up by cells of the individual and an immune response against the immunogen is induced in the individual. Methods of reducing rejection of unmatched donor cells, tissue or organ in an individual undergoing cell, tissue or organ transplantation are disclosed. The methods comprise administering to the individual, one or more nucleic acid molecules that comprise a nucleotide sequence that encodes a death signal or toxin and a nucleotide sequence that encodes a Major Histocompatibility Complex antigen that is matched to the donor cells, tissue or organ. The nucleotide sequences that encode the Major Histocompatibility Complex antigen and death signal or toxin are expressed when taken up by cells of the individual. T cell death through interaction with the death signal or toxin results in a reduction of rejection of unmatched donor cells, tissue or organ. Methods of reducing a dominant immune response in an individual and methods of expanding a subpopulation of T cells associated with a specific immune response are also described. Plasmids and compositions comprising plasmids useful for practicing the method are described.
    • 公开了在个体中诱导针对免疫原的免疫应答的方法。 所述方法包括向个体施用包含编码免疫原的核苷酸序列的一个或多个核酸分子和编码主要组织相容性复合物抗原的核苷酸序列。 编码免疫原和主要组织相容性复合物抗原的核苷酸序列在个体细胞吸收时被表达,并且在个体中诱导针对免疫原的免疫应答。 公开了在经历细胞,组织或器官移植的个体中减少不匹配的供体细胞,组织或器官的排斥的方法。 所述方法包括向个体施用包含编码死亡信号或毒素的核苷酸序列的一个或多个核酸分子和编码与供体细胞,组织或器官相匹配的主要组织相容性复合物抗原的核苷酸序列。 编码主要组织相容性复合物抗原和死亡信号或毒素的核苷酸序列由个体细胞摄取时表达。 通过与死亡信号或毒素的相互作用导致的T细胞死亡导致不匹配的供体细胞,组织或器官的排斥减少。 还描述了减少个体中显性免疫应答的方法和扩增与特异性免疫应答相关的T细胞亚群的方法。 描述了包含用于实施该方法的质粒的质粒和组合物。
