应用
TLR3可识别双链RNA并作为应对病毒病原体免疫反应的一种主要效应子。 聚肌胞苷-聚胞苷酸（Poly(I) • Poly(C)）是一种可作为在TLR3水平对细胞信号转导进行研究的模型RNA的双链均聚物。 Poly(IC)是一种TRIF依赖性toll样受体-3（TLR3）配体。
生化/生理作用
将Poly(I:C)转染至NIT-1细胞中，已被用作细胞内dsRNA诱导的β细胞凋亡的模型。转染后18小时，45％的细胞发生凋亡，并且其NF-kB、p50/p65核转位、caspase 3和8切割以及caspase 12的转录诱导、Fas、IL-15和TNF受体相关配体（TRAIL）水平均增加。有人提出Poly(I:C)是最合适的稳定成熟树突状细胞（DC）诱导剂之一。这些成熟DC能够在CD40连接后分泌生物活性IL-12，因此注射后能够在体内产生有效的免疫应答。Poly(I:C)被用作有效的佐剂，以增强对肽类疫苗的特异性抗肿瘤免疫应答。
其他说明
双链均聚物。
制备说明
本品需要离子强度，以维持双链结构。为了防止变形，可用生理性盐溶度（如盐水溶液）的溶液将其重悬。重悬过程可能需要加热（50 °C）及冷却以实现重新退火。
