    • A method and compound for suppressing an immune response in a mammalian subject, for the treatment or prevention of an autoimmune condition or transplantation rejection are disclosed. The compound is an antisense oligonucleotide analog compound having a targeting sequence complementary to a preprocessed CTLA-4 mRNA region identified by SEQ ID NO: 22 in SEQ ID NO: 1, spanning the splice junction between intron 1 and exon 2 of the preprocessed mRNA of the subject. The compound is effective, when administered to a subject, to form within host cells, a heteroduplex structure (i) composed of the preprocessed CTLA-4 mRNA and the oligonucleotide compound, (ii) characterized by a Tm of dissociation of at least 45° C., and (iii) resulting in an increased ratio of processed mRNA encoding ligand-independent CTLA-4 to processed mRNA encoding full-length CTLA-4.
    • 公开了用于抑制哺乳动物受试者的免疫应答的方法和化合物,用于治疗或预防自身免疫病症或移植排斥反应。 该化合物是具有与SEQ ID NO:1中SEQ ID NO:22鉴定的预处理的CTLA-4mRNA区域互补的靶序列的反义寡核苷酸类似物化合物,其跨越了预处理mRNA的内含子1和外显子2之间的剪接连接 主题。 该化合物在给受试者施用时在宿主细胞内形成,由预处理的CTLA-4mRNA和寡核苷酸化合物组成的异源双链体结构(i),(ii)特征在于解离的Tm至少为45° (iii)导致编码与配体无关的CTLA-4的加工的mRNA与编码全长CTLA-4的加工的mRNA的比例增加。
