In one aspect, the invention provides methods of increasing immune response by administering postcellular signaling factors produced by cells exposed to a stress condition. In one aspect, the invention provides methods of increasing immune response by administering in combination (a) a Stimulator of Interferon Genes (STING) agonist and (b) a purinergic receptor agonist. The increase in immune response may be used, for example, for treatment of infection or cancer. The invention also provides screening assays for identification of compounds that induce production of postcellular signaling factors which are also immunostimulatory agents. The invention further provides methods for identifying postcellular signaling factors with immunostimulatory activity. In another aspect, the invention provides methods of decreasing immune response by administering to a cell, tissue or subject a purinergic receptor antagonist alone or in combination with a Stimulator of Interferon Genes (STING) antagonist.
一方面,本发明提供了通过施用暴露于应激条件下的细胞产生的细胞后信号因子来提高免疫应答的方法。在一个方面,本发明提供了通过联合施用(a)干扰素基因刺激剂(STING)激动剂和(b)嘌呤能受体激动剂来增加免疫反应的方法。免疫反应的增强可用于治疗感染或癌症等。本发明还提供了筛选测定法,用于鉴定能诱导产生细胞后信号因子的化合物,这些细胞后信号因子也是免疫刺激剂。本发明进一步提供了鉴定具有免疫刺激活性的细胞后信号因子的方法。在另一方面,本发明提供了通过向细胞、组织或受试者单独施用嘌呤能受体拮抗剂或与干扰素基因刺激剂(STING)拮抗剂联合施用来降低免疫反应的方法。
