哮喘是一种以慢性炎症为特征的慢性过敏性疾病。I型和II型(CD 4+)T辅助细胞的平衡至关重要。在哮喘中,存在TH 2细胞因子如IL-4、IL-5和IL-13的过表达。编码这些细胞因子的基因位于人类相同的染色体区域5q31.1。在这里,我们证实了转录因子NFAT和GATA 3在调节人IL-4和IL-13中的核心作用。染色质构象捕获(3C)证明在人TH 2极化的HuT-78细胞中形成含有剪接的IL-4和IL-13 DNA序列的特异性连接产物。这表明在GATA 3和NFAT 1的控制下,TH 2细胞因子的协调表达是由于通过DNA成环形成染色质枢纽。
Asthma is a chronic allergic disorder characterised by chronic inflammation. The balance of type I and type II (CD4+) T helper cells is of critical importance. In asthma there is an overexpression of TH2 cytokines, such as IL-4, IL-5 and IL-13. The genes encoding these cytokines are located together the same chromosomal region, 5q31.1 in humans. Here we confirm a central role for the transcription factors NFAT and GATA3 in the regulation of human IL-4 and IL-13. Chromatin Conformation Capture (3C) demonstrated the formation of specific ligation products containing spliced IL-4 and IL-13 DNA sequences in human TH2 polarised HuT-78 cells. This suggests that co-ordinate expression of TH2 cytokines, under the control of GATA3 and NFAT1 is due to the formation of a chromatin hub by DNA looping.
