Through the expression of inflammatory mediators and immune-related molecules, epithelial cells function as immune effector cells in a wide variety of tissues; the expression of the CD40 receptor on these cells contributes this role. Engagement of CD40 activates epithelial cells and results in their release of pro- and anti-inflammatory mediators as well as pro-fibrotic molecules. As such, epithelial CD40 has been implicated in the pathogenesis of inflammatory disorders, generation of self-tolerance, and rejection of allografts.
通过炎症介质和免疫相关分子的表达,上皮细胞在多种组织中作为免疫效应细胞发挥作用;这些细胞上CD40受体的表达促成了这一作用。CD40的激活会使上皮细胞活化,并导致其释放促炎和抗炎介质以及促纤维化分子。因此,上皮细胞CD40与炎症性疾病的发病机制、自身耐受性的产生以及同种异体移植物的排斥反应有关。
