Allergy Asthma Immunol Res:1, 25-二羟维生素D3鼻内治疗能够减轻过敏性鼻炎症状

2019-02-04 AlexYang MedSci原创

维生素D是一种强有力的免疫调控因子。然而,在过敏性鼻炎中的角色仍旧不清楚。最近,有研究人员在过敏性鼻炎小鼠中评估了鼻内使用维生素D的抗过敏效果情况。研究人员将BALB/c小鼠在鼻内进行OVA鼻内挑战之前利用卵清蛋白(OVA)和明矾进行敏感化。之后,研究人员对其进行1, 25-二羟维生素D3给药或者溶剂给药。研究发现在治疗组,过敏性症状评分、嗜酸性粒细胞浸润和鼻组织中的IL-4和IL-13的mRNA

维生素D是一种强有力的免疫调控因子。然而,在过敏性鼻炎中的角色仍旧不清楚。最近,有研究人员在过敏性鼻炎小鼠中评估了鼻内使用维生素D的抗过敏效果情况。

研究人员将BALB/c小鼠在鼻内进行OVA鼻内挑战之前利用卵清蛋白(OVA)和明矾进行敏感化。之后,研究人员对其进行1, 25-二羟维生素D3给药或者溶剂给药。研究发现在治疗组,过敏性症状评分、嗜酸性粒细胞浸润和鼻组织中的IL-4和IL-13的mRNA水平与阳性对照组相比显著更低。IL-5 mRNA水平、血清总lgE和OVA特异性lgE和lgG1水平在治疗组降低;然而,上述差异并不显著。在颈部淋巴结(LNs)部位,CD86表达在治疗组中下调。另外,IL-4分泌在来源于LNs的淋巴培养物中显著减少。

最后,研究人员指出,他们的结果确定了1, 25-二羟维生素D3的抗过敏效果,能够降低CD11c+MHCIIhigh 细胞中CD86的表达和颈部LNs中2型T辅助细胞调控的炎症。因此,局部应用1, 25-二羟维生素D3可以作为过敏性鼻炎未来的一种治疗方法。
