T cell-derived IL-4 inhibits the expression of several inflammatory cytokine genes. In this study, IL-4 downregulated TNF-alpha and -beta, IL-1 beta IL-6 and IFN-gamma steady-state mRNA and protein production by blood leukocytes. In a detailed kinetic analysis, cytokine mRNA levels were significantly decreased in the presence of IL-4, suggesting an early and prolonged downregulatory effect. These findings support the general thesis that IL-4 is an important regulator of the inflammatory immune response.
T细胞衍生的白细胞介素-4抑制多种炎性细胞因子基因的表达。在本研究中,白细胞介素-4下调了血液白细胞中肿瘤坏死因子-α和-β、白细胞介素-1β、白细胞介素-6以及干扰素-γ的稳态信使核糖核酸(mRNA)和蛋白质生成。在一项详细的动力学分析中,在白细胞介素-4存在的情况下,细胞因子mRNA水平显著降低,提示存在早期且持久的下调效应。这些发现支持了白细胞介素-4是炎性免疫反应的重要调节因子这一总体论点。
