中文摘要
最近的研究表明,过敏性结膜炎患者角膜病变程度与结膜炎症程度之间存在相关性。包括我们在内的一些研究人员也证明,角膜成纤维细胞通过其有效释放/表达许多细胞因子、趋化因子和粘附分子而成为结膜炎症的促进剂。相比之下,角膜上皮细胞被认为是结膜炎症的淬灭剂,因为它们具有将角膜细胞与泪液中的生物活性物质分离的能力。在当前的研究中,使用大鼠实验性过敏性结膜炎模型,我们检查了角膜上皮剥离对1)结膜炎的临床表现,2)细胞因子、趋化因子和粘附分子的释放/表达的影响。结果1)角膜上皮剥脱可增强变应性结膜炎晚期的临床表现,但对角膜上皮的损伤程度无明显影响。它还增加了结膜中的嗜酸性粒细胞的数量在后期阶段。2)角膜上皮剥脱促进结膜组织中趋化因子TARC、RANTES、MCP-1和粘附分子ICAM-1的释放和表达。结论:(1)在大鼠实验性变应性结膜炎模型中,角膜上皮细胞作为变应性炎症的抑制剂,具有抑制炎症反应的作用。(2)在大鼠实验性变应性结膜炎模型中,角膜上皮细胞具有抑制炎症反应的作用。角膜上皮剥脱可能至少部分地通过激活角膜的结构细胞而增强变态反应的晚期。角膜上皮修复的延迟导致结膜过敏性炎症的恶化。
英文摘要
Recent studies have shown the correlation between the degree of corneal lesion and that of conjunctival inflammation in individuals with allergic conjunctivitis. It is also demonstrated by several researchers, including us, that corneal fibroblasts are the promoter of conjunctival inflammation through their potent release/expression of many cytokines, chemokines and adhesion molecules. In contrast, corneal epithelial cells are considered to be the quencher of conjunctival inflammation by their ability to separate corneal cells from bioactive substances in the tear fluids.In the current study, using rat experimental allergic conjunctivitis models, we examined the effect of corneal epithelial peeling on 1) clinical picture of conjunctivitis, 2)release/expression of cytokines, chemokines and adhesion molecules. We also examined 3) the effect of conjunctival allergic inflammation on the repair of corneal epithelium.Result1) Corneal epithelial peeling enhanced the clinical picture of the late phase of allergic conjunctivitis. It also enhanced the number of eosinophils in the conjunctiva at the late phase. It had no effect on the early phase.2) Corneal epithelial peeling enhanced the release/expression of chemokines TARC, RANTES, MCP-I and adhesion molecule ICAM-1 in the conjunctiva. It enhanced the release/expression of chemokines TARC, RANTES, IP-10, MCP-1 and adhesion molecule ICAM-1 and VCAM-1 in the cornea.3) Induction of allergic conjunctivitis delayed the repair of corneal epithelium.DiscussionIn rat experimental allergic conjunctivitis model, corneal epithelium serves as a quencher of allergic inflammation. Corneal epithelial peeling enhances the late phase of allergic reaction possibly, at least in part, through the activation of structural cells of the cornea. Delayed epithelial repair of the cornea contribute the exacerbation of allergic inflammation in the conjunctiva.
