J Immunol Res:双酚A会加重过敏性鼻炎的过敏性炎症

双酚A(BPA)存在于许多塑料制品中,因此是一种常见的环境内分泌干扰物。与塑料相关的健康问题,包括过敏性疾病,正引起越来越多的关注。然而,很少有研究探讨双酚A对过敏性鼻炎(AR)的影响。最近,有研究人员调查了双酚A是否与卵清蛋白(OVA)诱导的AR小鼠的过敏性炎症直接相关。

研究人员首先构建了OVA诱导的小鼠模型,在BPA给药后,研究人员评估了鼻腔症状,并通过ELISA检测了血清OVA特异性IgE水平。研究发现,与单纯OVA诱导的小鼠相比,添加BPA增加了鼻腔症状和血清OVA特异性IgE水平。与单独OVA暴露后相比,OVA和BPA共同暴露能够显著增加IL-4和IL-13蛋白水平。双酚A加OVA与单独暴露OVA后相比,IL-10蛋白水平趋于下降。与单独暴露于OVA后相比,OVA和BPA的共同暴露显著增加了GATA-3的mRNA水平,并降低了Foxp3和Helios的mRNA水平。与OVA单独暴露后的水平相比,BPA能够增加Th2细胞的比例,降低Tregs的比例。

BPA能够减少Tregs的比例

最后,研究人员指出,双酚A通过加剧AR过敏症状、增加血清中OVA特异性IgE水平以及损害Th2和Treg反应而产生不良作用。
