The disclosure features isolated polynucleotides, such as mRNAs, encoding a polypeptide that disrupts immune cell activity, such as T cell or B cell activity, including mRNAs comprising one or more modified nucleobase. The immune cell disruptor polynucleotides encode a polypeptide that comprises a first domain that mediates association of the polypeptide with an immune cell component and a second domain that mediates inhibition of immune cell activity when the polypeptide is expressed in the immune cell. The disclosure also features methods of using the same, for example, for inhibiting immune responses when administered to a subject, such as to inhibit autoimmune reactions.
该披露涉及孤立的多聚核苷酸,如编码破坏免疫细胞活性的多聚核苷酸,例如T细胞或B细胞活性的mRNA,包括包含一个或多个修饰的核碱基的mRNA。这些免疫细胞破坏多聚核苷酸编码一个包括第一个结构域的多肽,该结构域介导多肽与免疫细胞组分的结合,以及一个介导当多肽在免疫细胞中表达时抑制免疫细胞活性的第二结构域。该披露还涉及使用相同的方法,例如,将其用于向受试者施用时抑制免疫反应,例如用于抑制自身免疫反应。
