双链聚肌胞性质、用途与生产工艺

生物活性 Polyinosinic-polycytidylic acid sodium (Poly(I:C) sodium) 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 sodium 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。
靶点

TLR3, RIG-I, MDA5, apoptosis

体外研究

Polyinosinic-polycytidylic acid (20 ng/mL; 24 hours; WM793, WM278, WM239A, WM9 and 1205Lu cells) treatment strongly reduces viability from 100% in controls to 20%–50% within 24 hours.
Polyinosinic-polycytidylic acid (200 ng/mL; 24 hours; 1205Lu cells) treatment induces apoptosis in 1205Lu cells.
Polyinosinic-polycytidylic acid (3 ng/mL; 24 hours; 1205Lu cells) treatment induces IFN-β expression in melanoma cells. Silencing of RIG-I and MDA-5 confirmed that induction of IFN-β by Polyinosinic-polycytidylic acid required RIG-I and MDA-5, respectively, and that required IPS-1.
Polyinosinic-polycytidylic acid (5 ng/mL; 24 hours; 1205Lu cells) treatment reveals active subunits of caspase-9 and caspase-8 in melanoma cells.
Polyinosinic-polycytidylic acid sodium is prepared for injection by resuspending in sterile saline, heating to 50 °C at a concentration of 2 mg/ml to ensure complete solubilisation and then allowing to cool naturally to room temperature to ensure proper annealing of double-stranded RNA. Poly I:C is stored at -20 °C until use.
