Immunotherapy:MiR-146a类似物能够减轻过敏性鼻炎

2019-08-15 AlexYang MedSci原创

最近,有研究人员调查了microRNA(miR)-146a在过敏性鼻炎(AR)中的治疗潜力情况。研究人员将雌性BALB/c小鼠随机分配到AR和miR-146a组。在第21-28天每天进行卵清蛋白(OVA)挑战之前,研究人员进行了鼻孔miR-146a给药。研究发现,miR-146a的表达水平在AR鼻粘膜中显著减少。miR-146a类似物能够显著的减轻打喷嚏和挠鼻事件,并减少卵清蛋白特异性lgE水平,

最近,有研究人员调查了microRNA(miR)-146a在过敏性鼻炎(AR)中的治疗潜力情况。

研究人员将雌性BALB/c小鼠随机分配到AR和miR-146a组。在第21-28天每天进行卵清蛋白(OVA)挑战之前,研究人员进行了鼻孔miR-146a给药。研究发现,miR-146a的表达水平在AR鼻粘膜中显著减少。miR-146a类似物能够显著的减轻打喷嚏和挠鼻事件,并减少卵清蛋白特异性lgE水平,以及减少肥大细胞和嗜碱性细胞相关的炎症细胞因子水平,另外还能对辅助性T2释放因子产生影响。更多的是,miR-146a类似物能够抑制Toll样受体4(TLR4)/TRAF6/NF-κB信号通路相关蛋白的表达。

最后,研究人员指出,miR-146a在AR中的抗炎症作用可能是通过抑制Toll样受体4(TLR 4)/TRAF 6/NF-κB信号通路相关蛋白的表达来起作用的。
