MCE 國(guó)際站：Polyinosinic-polycytidylic acid

CAS：24939-03-5

品牌：MedChemExpress (MCE)

存儲(chǔ)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(dòng)劑。聚肌胞苷酸存在于某些病毒中，因此通常用于模擬細(xì)胞外 dsRNA 的作用。

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

體內(nèi)：Polyinosinic-polycytidylic acid (2.5-10 mg/mL, Stereotaxic injection, single dose) 在腦黑質(zhì)和背外側(cè)紋狀體中誘導(dǎo)持續(xù)的炎癥反應(yīng)[2]。 Polyinosinic-polycytidylic acid (10 μg/mouse, Intraperitoneal injection, single dose) 降低小鼠的肺腫瘤生長(zhǎng)[3]。 Polyinosinic-polycytidylic acid (1.25 mg/kg, Intraperitoneal injection, single dose) 在 MCAO 模型小鼠中通過(guò) TLR3 下調(diào)TLR4/MyD88 信號(hào)通路發(fā)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.
