Molecules:黄连碱能够抑制肥大细胞的脱粒和卵清蛋白诱导的过敏性鼻炎

2018-12-08 AlexYang MedSci原创

黄连碱是黄连异喹啉生物碱中的一种主要的组分。黄连碱对过敏性鼻炎的作用还没有调查。最近,有研究人员在小鼠模型中报道了黄连碱的作用的相关机制。研究发现,黄连碱能够显著的减少β-氨基己糖苷酶、组氨、白介素-4(IL-4)和肿瘤坏死因子α(TNF-α)的水平。黄连碱也能够预防形态学的变化,比如恢复长条形,抑制甲苯胺蓝染色颗粒的释放、重组抑制丝状肌动蛋白(F-actin)等。另外,黄连碱能够阻断磷酸肌醇3-

黄连碱是黄连异喹啉生物碱中的一种主要的组分。黄连碱对过敏性鼻炎的作用还没有调查。最近,有研究人员在小鼠模型中报道了黄连碱的作用的相关机制。

研究发现,黄连碱能够显著的减少β-氨基己糖苷酶、组氨、白介素-4(IL-4)和肿瘤坏死因子α(TNF-α)的水平。黄连碱也能够预防形态学的变化,比如恢复长条形,抑制甲苯胺蓝染色颗粒的释放、重组抑制丝状肌动蛋白(F-actin)等。另外,黄连碱能够阻断磷酸肌醇3-激酶(PI3K)/Akt在RBL-2H3细胞中的磷酸化。进一步的是,结果还表明了黄连碱能够抑制OVA诱导的过敏性鼻炎症状,比如鼻部摩擦和OVA诱导的特异性lgE、组氨、IL-4和TNF-α水平。

最后,研究人员指出,他们的数据表明了黄连碱对肥大细胞的炎症响应具有抑制作用,并且黄连碱有可能作为一种潜在的抗过敏药物。
