免疫调节细胞因子白细胞介素10(IL-10)主要由辅助性T细胞2型(TH 2)细胞表达,但在慢性感染期间也由TH 1细胞表达。在这里,我们观察到的可塑性IL-10和IL-13的表达慢性TH 1刺激后,此外,IL-10和IL-13的表达调控的转录因子E4 BP 4。慢性刺激的E4 BP 4缺陷型(Nfil 3 −/−;此处称为“E4 bp 4 −/− ")TH 1细胞、调节性T细胞(Treg细胞)和自然杀伤T细胞(NKT细胞)的IL-10和IL-13表达减弱。E4 bp 4的增强表达启动了常规TH 1细胞产生IL-10和IL-13。E4 bp 4 −/− TH 2细胞表现出IL-10产生受损,而对IL-13没有影响。我们的研究结果表明,E4 BP 4在控制TH 1细胞中IL-13和TH 1细胞、TH 2细胞、Treg细胞和NKT细胞中IL-10的可塑性方面具有多种功能。
The immunoregulatory cytokine interleukin 10 (IL-10) is expressed mainly by T helper type 2 (TH2) cells but also by TH1 cells during chronic infection. Here we observed plasticity in the expression of IL-10 and IL-13 after chronic TH1 stimulation; furthermore, the expression of Il10 and Il13 was regulated by the transcription factor E4BP4. Chronically stimulated E4BP4-deficient (Nfil3−/−; called ‘E4bp4−/−’ here) TH1 cells, regulatory T cells (Treg cells) and natural killer T cells (NKT cells) had attenuated expression of IL-10 and IL-13. Enforced expression of E4bp4 initiated the production of IL-10 and IL-13 by conventional TH1 cells. E4bp4−/− TH2 cells showed impairment of IL-10 production with no effect on IL-13. Our results indicate that E4BP4 has multiple functions in controlling the plasticity of IL-13 in TH1 cells and IL-10 in TH1 cells, TH2 cells, Treg cells and NKT cells.
NFIL3/E4BP4是在体内开发和成熟所必需的。
