调节性T细胞(Regulatory T cells,Tcells)是维持免疫稳态的重要介质。它们通过抑制炎症和促进自身耐受来调节免疫反应。除了它们的免疫调节作用外,越来越多的证据强调了TGFAP在血管生成(形成新血管的过程)中的动态作用。虽然血管生成对于正常组织再生至关重要,但它也是包括恶性肿瘤和慢性炎症在内的病理过程的标志。有趣的是,已显示TGFAP在血管生成中的作用是高度组织特异性和背景特异性的,因此可以产生促血管生成或抗血管生成作用。由于这些原因,有相当大的兴趣,在不同的疾病状态下,确定Treg介导的血管生成的调节的分子基础。本文综述了TGFAP在血管生成中的作用和TGFAP调节血管生成的机制,并讨论了这些机制在稳态和病理环境中的差异。
Regulatory T cells (Tregs) are crucial mediators of immune homeostasis. They regulate immune response by suppressing inflammation and promoting self-tolerance. In addition to their immunoregulatory role, a growing body of evidence highlights the dynamic role of Tregs in angiogenesis, the process of forming new blood vessels. Although angiogenesis is critically important for normal tissue regeneration, it is also a hallmark of pathological processes including malignancy and chronic inflammation. Interestingly, the role of Tregs in angiogenesis has been shown to be highly tissue- and context-specific and as a result, can yield either pro or antiangiogenic effects. For these reasons, there is considerable interest in determining the molecular underpinnings of Treg-mediated modulation of angiogenesis in different disease states. The present review summarizes the role of Tregs in angiogenesis and mechanisms by which Tregs regulate angiogenesis and discusses how these mechanisms differ in homeostatic and pathological settings.
