產(chǎn)品活性：Polyinosinic-polycytidylic acid (Poly(I:C)) 是雙鏈 RNA 的合成類似物，是一種 TLR3 和視黃酸誘導(dǎo)型基因 I 受體 (RIG-I 和 MDA5) 的激動劑,。Polyinosinic-polycytidylic acid 可以用作疫苗佐劑,，以增強(qiáng)先天性和適應(yīng)性免疫反應(yīng)，并改變腫瘤的微環(huán)境,，還可以直接觸發(fā)癌細(xì)胞發(fā)生凋亡 (apoptosis),。

生物活性：聚肌胞苷酸 (Poly(I:C)) 是一種合成的雙鏈 RNA (dsRNA)，是一種 Toll 樣受體 3 (TLR3) 激動劑,。聚肌胞苷酸存在于某些病毒中,，因此通常用于模擬細(xì)胞外 dsRNA 的作用。

體外：Polyinosinic-polycytidylic acid (0.5-5 μg/mL, 3-24 h) 呈現(xiàn)劑量和時間依賴性增加誘導(dǎo)永生化氣道上皮細(xì)胞的細(xì)胞旁通透性[4],。 Polyinosinic-polycytidylic acid (5 μg/mL, 24 h) 對 16HBE14o- 細(xì)胞沒有細(xì)胞毒性[4],。 Polyinosinic-polycytidylic acid (5 μg/mL, 6 h) 在 16HBE14o- 細(xì)胞中誘導(dǎo)上皮頂端連接復(fù)合體和緊密連接的破壞[4]。 MCE尚未獨(dú)立證實(shí)這些方法的準(zhǔn)確性,。僅供參考,。

體內(nèi)：Polyinosinic-polycytidylic acid (2.5-10 mg/mL, Stereotaxic injection, single dose) 在腦黑質(zhì)和背外側(cè)紋狀體中誘導(dǎo)持續(xù)的炎癥反應(yīng)[2]。 Polyinosinic-polycytidylic acid (10 μg/mouse, Intraperitoneal injection, single dose) 降低小鼠的肺腫瘤生長[3],。 Polyinosinic-polycytidylic acid (1.25 mg/kg, Intraperitoneal injection, single dose) 在 MCAO 模型小鼠中通過 TLR3 下調(diào)TLR4/MyD88 信號通路發(fā)揮腦缺血再灌注損傷的治療作用[5],。 MCE has not independently confirmed the accuracy of these methods. They are for reference only.
