    • The present invention provides methods and compositions for modulating an individual's immune response to antigens. It is an aspect of the present invention that allergic responses to antigens, which in some cases lead to asthma and even anaphylaxis, can be treated or prevented by administering compositions having immunostimulatory oligonucleotides having unmethylated CpG sequences. It is another aspect of the present invention that allergies to antigens, especially one that result in asthma and anaphylaxis, can be treated or prevented by administering compositions containing immunostimulatory oligonucleotides having unmethylated CpG dinucleotide sequences and further comprising antigen(s), fragments of the antigen, mixtures of fragments of the antigen, antigens modified to reduce Th2-type immune responses, and fragments of the antigen modified to reduce Th2-type immune responses. Cellular systems for studying immunostimulation by CpG containing nucleic acids include in vivo, in vitro or ex vivo systems.
    • 本发明提供了调节个体对抗原的免疫应答的方法和组合物。 本发明的一个方面是通过施用具有具有非甲基化CpG序列的免疫刺激性寡核苷酸的组合物来治疗或预防对某些情况下导致哮喘甚至过敏反应的抗原的过敏反应。 本发明的另一方面是通过施用含有具有非甲基化CpG二核苷酸序列的免疫刺激性寡核苷酸的组合物,并且进一步包含抗原,抗原片段,可以治疗或预防抗原,特别是导致哮喘和过敏反应的抗原 ,抗原片段的混合物,被修饰以减少Th2型免疫应答的抗原,以及被修饰以减少Th2型免疫应答的抗原片段。 用于研究含有CpG的核酸的免疫刺激的细胞系统包括体内,体外或离体系统。
