哮喘是一种阻塞性炎症性气道疾病。气道阻塞是由气道平滑肌细胞的高反应性收缩介导的,这种收缩是由T淋巴细胞引起的炎症诱导和复合的。参与这些细胞类型的活化的一个重要信号转导途径涉及称为二酰基甘油(DAG)的脂质第二信使的产生。DAG水平在细胞中由称为DAG激酶(DGK)的负调节剂控制。本文就DAG信号通路在变应性气道疾病和哮喘中如何减弱免疫细胞和气道平滑肌细胞的病理功能进行综述。此外,我们还讨论了如何通过抑制DGK来增强DAG信号通路可能代表这些疾病的一种新的治疗策略。
Asthma is an obstructive inflammatory airway disease. Airway obstruction is mediated by hyperresponsive airway smooth muscle cell contraction, which is induced and compounded by inflammation caused by T lymphocytes. One important signal transduction pathway that is involved in the activation of these cell types involves the generation of a lipid second messenger known as diacylglycerol (DAG). DAG levels are controlled in cells by a negative regulator known as DAG kinase (DGK). In this review, we discuss how the DAG signaling pathway attenuates the pathological function of immune cells and airway smooth muscle cells in allergic airway disease and asthma. Furthermore, we discuss how the enhancement of the DAG signaling pathway through the inhibition of DGK may represent a novel therapeutic strategy for these diseases.
