Polyinosinic-polycytidylic acid

MCE 國際站：Polyinosinic-polycytidylic acid

CAS：24939-03-5

品牌：MedChemExpress (MCE)

存儲條件：Powder: -20°C, 3 years.In solvent: -80°C, 6 months; -20°C, 1 month.

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胞外 dsRNA 的作用。

體外：Polyinosinic-polycytidylic acid (0.5-5 μg/mL, 3-24 h) 呈現劑量和時間依賴性增加誘導永生化氣道上皮細胞的細胞旁通透性[4]。 Polyinosinic-polycytidylic acid (5 μg/mL, 24 h) 對 16HBE14o- 細胞沒有細胞毒性[4]。 Polyinosinic-polycytidylic acid (5 μg/mL, 6 h) 在 16HBE14o- 細胞中誘導上皮頂端連接復合體和緊密連接的破壞[4]。 MCE has not independently confirmed the accuracy of these methods. They are for reference only.

體內：Polyinosinic-polycytidylic acid (2.5-10 mg/mL, Stereotaxic injection, single dose) 在腦黑質和背外側紋狀體中誘導持續的炎癥反應[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TLR4/MyD88 信號通路發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. Animal Model: lung tumor-bearing mice[3] Dosage: 10 μg/mouse Administration: Intraperitoneal injection (i.p.) Result: Induced a significant decrease in the growth of pulmonary metastases in tumor-bearing mice. Reduced the amount of lung foci to ≈ 40%. Significantly increased BAL fluid cell numbers. Increased the level of INF-γ and IL-17A, decreased the levels of IL-13. Increased TLR3 expression. Animal Model: Middle cerebral artery occlusion (MCAO) model mice[5] Dosage: 1.25 mg/kg Administration: Intraperitoneal injection (i.p.) Result: Reduced focal cerebral I/R injury. Increased the expression of Bcl2, Hsp27, and Hsp70, decreased Bax expression, and reduced cellular degeneration and apoptosis. Protected against cerebral ischemia and conferred protection against cerebral I/R injury through the downregulation of TLR4 signaling via TLR3.
