项目摘要
It is well known that type 2 immunity is important for allergicinflammation. To examine how IL-4 or IL-13, signature type 2 cytokines, contributes to the pathogenesis of allergic inflammation, we in this study analyzed functions of periostin,an extracellular matrix protein induced by IL-4 or IL-13. We found that periostin playsan important role for the chronicity of allergic inflammation in atopic dermatitis. IL-4 or IL-13 induces periostin production in fibroblasts. Periostin induces TSLP production in keratinocytes by binding to integrin molecules on their cell surface. Then TSLP induces Th2 differentiation in naive T cells. Thus, the vicious cycle composed of IL-4/IL-13, periostin, integrin, and TSLP is important for the pathogenesisof atopic dermatitis. The finding that the neutralizing antibodies against av integrin inhibited dermatitis suggests that periostin can be a therapeutic target against atopic dermatitis. We also found that periostin is involved in the pathogenesis of variousinflammatory diseases such as pulmonary fibrosis, scleroderma, gallbladder carcinoma,IgG4-related sclerosing sialadenitis, eosinophilic otitis media, allergic rhinitis and chronic rhinosinusitis, and proliferative diabetic retinopathy. Furthermore, we found that periostin plays an important role in wound repair, which is a physiological function of periostin. The underlying mechanism of the chronicity of allergic inflammationby periostin is the first example showing some host factor is involved in it. It is hopedthat development of inhibitors targeting periostin will lead to development of therapeutic agents against atopic dermatitis having a novel mechanism.
众所周知,2型免疫对于过敏性炎症是重要的。为了研究IL-4或IL-13,标志性2型细胞因子,如何有助于过敏性炎症的发病机制,我们在这项研究中分析了骨膜蛋白,IL-4或IL-13诱导的细胞外基质蛋白的功能。我们发现骨膜蛋白在特应性皮炎变应性炎症的慢性化中起重要作用。IL-4或IL-13诱导成纤维细胞中的骨膜蛋白产生。骨膜蛋白通过与角质形成细胞表面的整合素分子结合诱导角质形成细胞产生TSLP。然后TSLP诱导初始T细胞中的Th 2分化。因此,IL-4/IL-13、骨膜蛋白、整合素和TSLP组成的恶性循环在特应性皮炎的发病机制中是重要的。抗α v整联蛋白中和抗体抑制皮炎的发现表明骨膜蛋白可以成为特应性皮炎的治疗靶点。我们还发现骨膜蛋白参与了多种炎症性疾病的发病机制,如肺纤维化、硬皮病、胆囊癌、IgG 4相关的硬化性涎腺炎、嗜酸性中耳炎、变应性鼻炎和慢性鼻窦炎以及增殖性糖尿病视网膜病变。此外,我们发现骨膜蛋白在创伤修复中起重要作用,这是骨膜蛋白的生理功能。骨膜蛋白致过敏性炎症慢性化的潜在机制是第一个显示宿主因子参与其中的例子,希望开发以骨膜蛋白为靶点的抑制剂将导致开发具有新机制的特应性皮炎治疗药物。
