先天性淋巴样细胞(ILC)位于粘膜表面并控制对肠道感染的免疫。2型先天性淋巴样细胞(ILC 2)产生细胞因子,如IL-5和IL-13,是对抗蠕虫感染的免疫防御所必需的,并参与气道高反应性的发病机制。在这里,我们研究了转录因子GATA 3对ILC 2分化和维持的作用。我们发现,ILC 2和它们的谱系特异性骨髓前体(ILC 2 P),如这里所确定的,其特征在于连续高表达的GATA 3。对所有ILC中GATA 3暂时缺失的小鼠的分析表明,GATA 3是ILC 2的分化和维持所必需的,但不是RORγt+ ILC所必需的。因此,我们的数据表明GATA 3对于ILC 2命运决定是必不可少的,并揭示了控制ILC和T辅助细胞命运的转录程序之间的相似性。
Innate lymphoid cells (ILCs) reside at mucosal surfaces and control immunity to intestinal infections. Type 2 innate lymphoid cells (ILC2) produce cytokines such as IL-5 and IL-13 and are required for immune defense against helminth infections and are involved in the pathogenesis of airway hyperreactivity. Here, we have investigated the role of the transcription factor GATA3 for ILC2 differentiation and maintenance. We showed that ILC2 and their lineage-specified bone marrow precursor (ILC2P), as identified here, were characterized by continuous high expression of GATA3. Analysis of mice with temporary deletion of GATA3 in all ILCs showed that GATA3 was required for the differentiation and maintenance of ILC2 but not for RORγt+ ILCs. Thus, our data demonstrate GATA3 is essential for ILC2 fate decisions, and reveal similarities between the transcriptional programs controlling ILC and T helper cell fates.
