产品活性：Polyinosinic-polycytidylic acid (Poly(I:C)) 是双链 RNA 的合成类似物，是一种 TLR3 和视黄酸诱导型基因 I 受体 (RIG-I 和 MDA5) 的激动剂。Polyinosinic-polycytidylic acid 可以用作疫苗佐剂，以增强先天性和适应性免疫反应，并改变肿瘤的微环境，还可以直接触发癌细胞发生凋亡 (apoptosis)。

生物活性：聚肌胞苷酸 (Poly(I:C)) 是一种合成的双链 RNA (dsRNA)，是一种 Toll 样受体 3 (TLR3) 激动剂。聚肌胞苷酸存在于某些病毒中，因此通常用于模拟细胞外 dsRNA 的作用。

体外：Polyinosinic-polycytidylic acid (0.5-5 μg/mL, 3-24 h) 呈现剂量和时间依赖性增加诱导永生化气道上皮细胞的细胞旁通透性[4]。 Polyinosinic-polycytidylic acid (5 μg/mL, 24 h) 对 16HBE14o- 细胞没有细胞毒性[4]。 Polyinosinic-polycytidylic acid (5 μg/mL, 6 h) 在 16HBE14o- 细胞中诱导上皮顶端连接复合体和紧密连接的破坏[4]。 MCE尚未独立证实这些方法的准确性。仅供参考。

体内：Polyinosinic-polycytidylic acid (2.5-10 mg/mL, Stereotaxic injection, single dose) 在脑黑质和背外侧纹状体中诱导持续的炎症反应[2]。 Polyinosinic-polycytidylic acid (10 μg/mouse, Intraperitoneal injection, single dose) 降低小鼠的肺肿瘤生长[3]。 Polyinosinic-polycytidylic acid (1.25 mg/kg, Intraperitoneal injection, single dose) 在 MCAO 模型小鼠中通过 TLR3 下调TLR4/MyD88 信号通路发挥脑缺血再灌注损伤的治疗作用[5]。 MCE has not independently confirmed the accuracy of these methods. They are for reference only.
