目的
2
局部免疫球蛋白高表达是慢性鼻窦炎伴鼻息肉(CRSwNP)重要病理特征,本研究主要探讨亚洲CRSwNP中边缘区 B 和 B-1 (MZB1)与局部免疫球蛋白表达的关系。
方法
2
通过聚合酶链式反应(PCR)、luminex、免疫组化染色对40例CRSwNP患者的鼻息肉组织和6名健康对照者的下鼻甲分别进行mRNA水平和蛋白质水平的检测,通过单因素方差分析、独立样本
t
检验和Pearson相关性分析进行统计检验。
结果
2
与健康对照组相比,2型CRSwNP中
MZB1
(
P
<0.01)和
HSP90B1
(
P
<0.01)的mRNA表达水平显著升高,免疫组织化学染色显示MZB1蛋白表达在2型CRSwNP中表达显著增加。此外,MZB1与鼻息肉组织中的免疫球蛋白E(IgE)的表达呈线性相关(
P
<0.01,
r
=0.52)。MZB1与2型CRSwNP鼻息肉组织中的白细胞介素-5(IL-5)(
P
<
0.05,
r
=0.4)、白细胞介素-13,( IL-13)(
P
<
0.05,
r
=0.44)的表达也呈线性相关。MZB1与鼻息肉组织嗜酸性粒细胞数线性相关有统计学意义(
P
<
0.05,
r
=0.72)。
结论
2
与对照组相比,MZB1在亚洲CRSwNP中表达显著增加,尤其是2型CRSwNP,并且与鼻息肉组织中IgE的高表达和CRSwNP疾病严重程度相关。
Objective
2
The heightened expression of local immunoglobulins is a significant pathological characteristic of chronic rhinosinusitis with nasal polyps (CRSwNP), particularly in the Asian population. This study is centered on exploring the association between MZB1 and the localized aggregation of immunoglobulins in Asian individuals with CRSwNP.
Methods
2
Nasal polyp tissues obtained from 40 CRSwNP patients and inferior turbinates from 6 healthy controls underwent examination for both mRNA and protein levels. The assessments were conducted using polymerase chain reaction, luminex, and immunohistochemical staining. Statistical analyses, including one-way Anova (ANOVA), independent samples
t
-test, and Pearson's correlation analysis, were employed for comprehensive data evaluation.
Results
2
The mRNA expression levels of MZB1(
P
<
0.01) and
HSP90B1
(
P
<
0.01) were significantly higher in type 2 CRSwNP patients compared with those in healthy controls. Immunohistochemical staining revealed a significant increase in MZB1 protein expression in type 2 CRSwNP. MZB1 demonstrated correlation with the expression of immunoglobulin E in nasal polyp tissues (
P
<
0.01,
r
= 0.52). Additionally,MZB1correlated with the expression ofIL-5(
P
<
0.05,
r
= 0.4) and IL-13 (
P
<
0.05,
r
= 0.44) in nasal polyp tissues. Furthermore,MZB1showed correlation with the number of eosinophils in nasal polyp tissues (
P
<
0.05,
r
= 0.72).
Conclusion
2
The expression of MZB1 is notably elevated in Asian CRSwNP, particularly in type 2 CRSwNP, when compared with controls.MZB1expression correlates significantly with high IgE expression and disease severity in nasal polyp tissues.
