Abstract

Angiogenesis and lymphangiogenesis, the growth of new vessels from preexisting ones, have received increasing interest due to their role in tumor growth and metastatic spread. However, vascular remodeling, associated with vascular hyperpermeability, is also a key feature of many chronic inflammatory diseases including asthma, atopic dermatitis, psoriasis, and rheumatoid arthritis. The major drivers of angiogenesis and lymphangiogenesis are vascular endothelial growth factor- (VEGF-)A and VEGF-C, activating specific VEGF receptors on the lymphatic and blood vascular endothelium. Recent experimental studies found potent anti-inflammatory responses after targeted inhibition of activated blood vessels in models of chronic inflammatory diseases. Importantly, our recent results indicate that specific activation of lymphatic vessels reduces both acute and chronic skin inflammation. Thus, antiangiogenic and prolymphangiogenic therapies might represent a new approach to treat chronic inflammatory disorders, including those due to chronic allergic inflammation.

摘要

血管生成和淋巴管生成,即从已有的血管生长出新的血管,因其在肿瘤生长和转移扩散中的作用而受到越来越多的关注。然而,与血管通透性增加相关的血管重塑也是许多慢性炎症性疾病的关键特征,包括哮喘、特应性皮炎、银屑病和类风湿性关节炎。血管生成和淋巴管生成的主要驱动因素是血管内皮生长因子(VEGF)-A和VEGF-C,它们激活淋巴管和血管内皮上的特定VEGF受体。最近的实验研究发现,在慢性炎症性疾病模型中,靶向抑制活化血管后会产生强大的抗炎反应。重要的是,我们最近的结果表明,淋巴管的特异性激活可减轻急性和慢性皮肤炎症。因此,抗血管生成和促淋巴管生成疗法可能代表了一种治疗慢性炎症性疾病的新方法,包括那些由慢性过敏性炎症引起的疾病。
