INTRODUCTION T helper type 9 (Th9) cells have been shown to play a key role in initiating allergic reactions and promoting airway inflammation. However, to the best of our knowledge, their role has not been analyzed in infants with recurrent wheezing. MATERIAL AND METHODS We performed a case-control study including 34 infants with recurrent wheezing and the same number of healthy infants as controls; all subjects were aged 1- to 3-years-old. The Th9 cell populations in the peripheral blood of these subjects were analyzed using flow cytometry, along with the assessment of Th9- and Th2-related plasma cytokine levels, including interleukin (IL)-1β, IL-4, IL-5, IL-9, IL-10, IL-13, IL-17A, and IL-33, and transforming growth factor β1 (TGF-β1) using a Luminex 200 immunoassay. RESULTS Our results indicatedthat infants with recurrent wheezing had higher percentages of Th9 cells (median, 0.69%; range, 0.46-1.08%) as compared to healthy infants (median, 0.25%, range, 0.13-0.36%; p < 0.05). In addition, infants with recurrent wheezing also exhibited higher plasma levels of cytokines IL-4, IL-9, IL-10, IL-33, and TGF-β1. Furthermore, the percentage of Th9 cells was positively correlated with the levels of IL-4 (r = 0.408, p < 0.05) and IL-9 (r = 0.644, p < 0.05) in the peripheral blood of wheezing infants. CONCLUSIONS Our findings suggest that the percentage of Th9 cells is increased in infants with recurrent wheezing; thus, Th9 cells may play an important role in the pathogenesis of recurrent wheezing.

反复喘息婴儿外周血Th9细胞群及相关细胞因子的变化。

引言 T 辅助 9 型 (Th9) 细胞已被证明在引发过敏反应和促进气道炎症中起关键作用。然而,据我们所知,尚未分析它们在反复喘息婴儿中的作用。材料与方法 我们进行了一项病例对照研究,包括 34 名反复喘息的婴儿和与对照组相同数量的健康婴儿。所有受试者的年龄为 1 至 3 岁。使用流式细胞术分析这些受试者外周血中的 Th9 细胞群,同时评估 Th9 和 Th2 相关的血浆细胞因子水平,包括白细胞介素 (IL)-1β、IL-4、IL-5、IL- 9、IL-10、IL-13、IL-17A 和 IL-33,以及使用 Luminex 200 免疫测定法的转化生长因子 β1 (TGF-β1)。结果 我们的结果表明,与健康婴儿(中位数,0.25%,范围,0.13-0.36%;p < 0.05)相比,反复喘息婴儿的 Th9 细胞百分比更高(中位数,0.69%;范围,0.46-1.08%)。此外,反复喘息婴儿的血浆细胞因子 IL-4、IL-9、IL-10、IL-33 和 TGF-β1 水平也较高。此外,Th9细胞百分比与喘息婴儿外周血中IL-4(r = 0.408,p < 0.05)和IL-9(r = 0.644,p < 0.05)水平呈正相关。结论 我们的研究结果表明,反复喘息婴儿的 Th9 细胞百分比增加。因此,Th9 细胞可能在反复喘鸣的发病机制中起重要作用。0.13-0.36%;p < 0.05)。此外,反复喘息婴儿的血浆细胞因子 IL-4、IL-9、IL-10、IL-33 和 TGF-β1 水平也较高。此外,Th9细胞百分比与喘息婴儿外周血中IL-4(r = 0.408,p < 0.05)和IL-9(r = 0.644,p < 0.05)水平呈正相关。结论 我们的研究结果表明,反复喘息婴儿的 Th9 细胞百分比增加。因此,Th9 细胞可能在反复喘鸣的发病机制中起重要作用。0.13-0.36%;p < 0.05)。此外,反复喘息婴儿的血浆细胞因子 IL-4、IL-9、IL-10、IL-33 和 TGF-β1 水平也较高。此外,Th9细胞百分比与喘息婴儿外周血中IL-4(r = 0.408,p < 0.05)和IL-9(r = 0.644,p < 0.05)水平呈正相关。结论 我们的研究结果表明,反复喘息婴儿的 Th9 细胞百分比增加。因此,Th9 细胞可能在反复喘鸣的发病机制中起重要作用。05)在喘息婴儿的外周血中。结论 我们的研究结果表明,反复喘息婴儿的 Th9 细胞百分比增加。因此,Th9 细胞可能在反复喘鸣的发病机制中起重要作用。05)在喘息婴儿的外周血中。结论 我们的研究结果表明,反复喘息婴儿的 Th9 细胞百分比增加。因此,Th9 细胞可能在反复喘鸣的发病机制中起重要作用。
