过敏性哮喘是一种复杂的慢性炎症性疾病,与气道高反应性 (AHR) 相关,并由 Th2 细胞因子分泌驱动。 2 型先天淋巴细胞 (ILC2) 产生大量 Th2 细胞因子,有助于 AHR 的发生。在这里,我们证明 ILC2 表达 α7-烟碱乙酰胆碱受体 (α7nAChR),该受体被认为在多种炎症性疾病中具有抗炎作用。我们发现,特定激动剂与 ILC2 上的 α7nAChR 结合可降低 ILC2 效应器功能并抑制 ILC2 依赖性 AHR,同时降低 ILC2 关键转录因子 GATA-3 和关键炎症调节剂 NF-κB 的表达,并降低上游激酶 IKKα/β 的磷酸化。此外,在人源化 ILC2 小鼠模型中,特定的 α7nAChR 激动剂可减少细胞因子的产生和 AHR。总的来说,我们的数据表明,ILC2 表达的 α7nAChR 是治疗 ILC2 介导的哮喘的潜在治疗靶点。 气道高反应性是由 ILC2 和 Th2 细胞产生的 2 型细胞因子驱动的。在这里,作者表明,α7-烟碱受体激动剂 (GTS-21) 可以抑制 ILC2 反应,并且可以在人源化小鼠模型中治疗链格孢属诱导的气道高反应性。
Allergic asthma is a complex and chronic inflammatory disorder that is associated with airway hyperreactivity (AHR) and driven by Th2 cytokine secretion. Type 2 innate lymphoid cells (ILC2s) produce large amounts of Th2 cytokines and contribute to the development of AHR. Here, we show that ILC2s express the α7-nicotinic acetylcholine receptor (α7nAChR), which is thought to have an anti-inflammatory role in several inflammatory diseases. We show that engagement of a specific agonist with α7nAChR on ILC2s reduces ILC2 effector function and represses ILC2-dependent AHR, while decreasing expression of ILC2 key transcription factor GATA-3 and critical inflammatory modulator NF-κB, and reducing phosphorylation of upstream kinase IKKα/β. Additionally, the specific α7nAChR agonist reduces cytokine production and AHR in a humanized ILC2 mouse model. Collectively, our data suggest that α7nAChR expressed by ILC2s is a potential therapeutic target for the treatment of ILC2-mediated asthma. Airway hyperreactivity is driven by type 2 cytokines produced by ILC2 and Th2 cells. Here the authors show that an α7-nicotinic receptor agonist (GTS-21) inhibits ILC2 responses and is therapeutic against Alternaria-induced airway hyperreactivity in a humanized mouse model.
