PolyiNOSinic-polycytidylic acid sodium 是双链 RNA 的合成类似物,是TLR3和视黄酸诱导型基因 I 受体激动剂。它可以用作疫苗佐剂,直接触发癌细胞发生凋亡,还增强先天性和适应性免疫反应,并改变肿瘤的微环境。
产品描述
Polyinosinic-polycytidylic acid sodium is a synthetic analog of double-stranded RNA and an agonist of toll-like receptor 3 (TLR3) and retinoic acid inducible gene I (RIG-I)-like receptors (RIG-I and MDA5).
体外活性
Polyinosinic-polycytidylic acid (polyi:c) is a synthetic analog of double-stranded RNA and an agonist of toll-like receptor (TLR) 3 and retinoic acid inducible gene I (RIG-I)-like receptors (RLRs), including RIG-I and melanoma differentiation-associated gene 5 (MDA5).?The effect of polyi:c on tumor immunotherapy has been well explored for several decades.?The accumulated evidence suggests that polyi:c could be used as a vaccine adjuvant to enhance innate and adaptive immune responses, and to alter the tumor microenvironment.?Recent studies have also shown that activation of TLR3 and RLR signaling by polyi:c can directly trigger apoptosis in some cancer cells[2].
体内活性
Polyinosinic-polycytidylic acid inhibits tumor growth in NOD/SCID immunodeficient mice injected with 1205Lu cells. The level of human DNA is 50% lower in mice treated with Polyinosinic-polycytidylic acid[1].
