    摘要： Novel oligonucleotides having immune inhibitory effects, and methods for their use, are provided. The inhibitory oligonucleotides include those that specifically inhibit certain Toll-like receptors, including TLR7, TLR8, and TLR9. Certain of the immunoinhibitory oligonucleotides inhibit a combination of TLRs selected from TLR7, TLR8, and TLR9. Inhibitors of TLR9 are characterized by a 5′ CC dinucleotide appropriately spaced upstream of a G-rich oligomer. Inhibitors of TLR8 include specific simple dinucleotides and oligonucleotides ending at their 3′ termini with the specific dinucleotides. TLR7 inhibitors include oligonucleotides having a phosphorothioate backbone. Also provided are combinations and conjugates involving the inhibitory oligonucleotides of the invention and other agents, where the other agents include TLR agonists and antigens. Compositions of the invention can be used to shape an immune response, reduce unwanted specific TLR-mediated immunostimulation, and to treat conditions including allergy, asthma, infection, and cancer.

    摘要翻译： 提供了具有免疫抑制作用的新型寡核苷酸及其使用方法。 抑制性寡核苷酸包括特异性抑制某些Toll样受体的那些，包括TLR7，TLR8和TLR9。 某些免疫抑制性寡核苷酸抑制了选自TLR7，TLR8和TLR9的TLR的组合。 TLR9的抑制剂的特征在于在富G寡聚体上游适当间隔5'CC二核苷酸。 TLR8的抑制剂包括特异性简单二核苷酸和寡核苷酸终止于其3'末端与特异性二核苷酸。 TLR7抑制剂包括具有硫代磷酸酯骨架的寡核苷酸。 还提供了涉及本发明的抑制性寡核苷酸和其它试剂的组合和缀合物，其中其它试剂包括TLR激动剂和抗原。 可以使用本发明的组合物来形成免疫应答，减少不需要的特异性TLR介导的免疫刺激，并且治疗包括变态反应，哮喘，感染和癌症的病症。
