Front Neurosci:香烟烟雾对鼻呼吸道和嗅觉粘膜影响研究

香烟烟雾(CS)能够加重过敏气道炎症。然而,一些研究表明抽烟与低风险过敏性鼻炎相关。因此,CS对过敏性鼻炎的影响仍旧不清楚。最近,有研究人员调查了CS对过敏性鼻炎小鼠呼吸道粘膜(RM)和嗅觉上皮(OE)的影响,并且上述影响可能依赖鼻组织组成的不同而有所差异。

研究人员使用的是8周大的雄性BALB/c小鼠。研究人员通过鼻内给药10个剂量的CS溶液(CSS)建立了一个抽烟小鼠模型,过敏性鼻炎小鼠模型则通过腹腔卵清蛋白(OVA)注射和鼻内OVA挑战来建立。研究人员通过组织学、血清和遗传分析调查了CS对有或无过敏性鼻炎小鼠的鼻RM和OE影响。研究发现,尽管CSS不能够诱导过敏性响应或者RM和OE损伤,短期CSS处理能够增强过敏性响应,包括增加嗜酸性细胞和炎症细胞的浸润,并上调OVA敏化小鼠鼻RM中白介素-5的表达。明显的是,重复的OVA敏化能够损伤部分OE,但在OVA诱导的过敏小鼠中,CSS处理不能恢复上述损伤。

最后,研究人员指出,短期CSS接触能够增强鼻RM中的过敏响应,并不改变OE的结构。这些结果表明了过敏性鼻炎患者可能经历了CS后过敏症状加重的情况。
