Application
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。
Biochem/physiol Actions
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。
Preparation Note
该产物需要离子强度以维持其双链结构。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。
Other Notes

Foxp3+ regulatory T (Treg) cells restrict immune pathology in inflamed tissues; however, an inflammatory environment presents a threat to Treg cell identity and function. Here, we establish a transcriptional signature of central nervous system (CNS) Treg cells that accumulate during

The integrated stress response (ISR) is a cellular response system activated upon different types of stresses, including viral infection, to restore cellular homeostasis. However, many viruses manipulate this response for their own advantage. In this study, we investigated the association
