Allergy Asthma Immunol Res:慢性鼻窦炎不同亚型中鼻组织特征性细胞因子研究

2019-02-03 AlexYang MedSci原创

慢性鼻窦炎(CRS)的内分型在过去十年已经建立。然而,CRS准确的免疫情况仍旧还存在矛盾,原因是其具有很多的免疫异质性。因此,最近有研究人员根据慢性鼻窦炎不同鼻组织调查了不同的免疫调节因子情况,并做了相关比较。研究人员从对照、不具有NP的CRS患者(CRSsNP)和具有NP的CRS患者(CRSwNP)中分别搜集了钩突粘膜(UP)和鼻息肉(NP)组织。研究发现,在嗜酸性NP患者中,特征性炎症调控因子

慢性鼻窦炎(CRS)的内分型在过去十年已经建立。然而,CRS准确的免疫情况仍旧还存在矛盾,原因是其具有很多的免疫异质性。因此,最近有研究人员根据慢性鼻窦炎不同鼻组织调查了不同的免疫调节因子情况,并做了相关比较。

研究人员从对照、不具有NP的CRS患者(CRSsNP)和具有NP的CRS患者(CRSwNP)中分别搜集了钩突粘膜(UP)和鼻息肉(NP)组织。研究发现,在嗜酸性NP患者中,特征性炎症调控因子包括白介素-5(IL-5)、C-C基序趋化因子配体-24(CCL-24)、单核细胞趋化蛋白-4(MCP-4)和血管细胞粘附因子-1(VCAM-1),而非嗜酸性NP患者中的特征性因子包括IL-17A、IL-1β和基质金属肽酶-9(MMP-9)。尽管在嗜酸性和非嗜酸性NP之间,炎症细胞因子存在差异,在同一受试者中,与UP相比,NP中的IL-5、CCL-11、IL-23、IL-2Rα、VCAM-1、MMP-3和MMP-9均上调。在主成分分析中(PCA),研究人员观察到Th2免疫响应在区分CRS亚型不同鼻组织中是有用的,并且在非嗜酸性NP和嗜酸性NP之间具有部分重叠。

最后,研究人员指出,不考虑CRS亚型且与UP相比,NP中上调的调节因子为Th2相关的,而不同的NP亚型中,特征性标记是不同的。不考虑CRSwNP亚型,他们的发现表明了Th2炎症响应因子在NP的发展过程中具有作用。
