The exact etiology and pathology of IBD remain unknown. Available evidence suggests that an abnormal immune response against the microorganisms in the intestine is responsible for the disease in genetically susceptible individuals. Dysregulation of immune response in the intestine plays a critical role in the pathogenesis of IBD, involving a wide range of molecules including cytokines. On the other hand, besides T helper (Th) 1 and Th2 cell immune responses, other subsets of T cells, namely Th17 and regulatory T cells, are likely associated with disease progression. Studying the interactions between various constituents of the innate and adaptive immune systems will certainly open new horizons of the knowledge about the immunologic mechanisms in IBD.

银屑病是一种免疫介导的多基因遗传性皮肤病,其发病机制尚未明确,目前认为可能是遗传、环境和免疫学因素共同作用的结果,在免疫机制方面,白细胞介素(interleukin,IL)-23 /辅助T细胞(helper T cells,Th)17途径已被确定为关键轴,促炎细胞...银屑病是一种免疫介导的多基因遗传性皮肤病,其发病机制尚未明确,目前认为可能是遗传、环境和免疫学因素共同作用的结果,在免疫机制方面,白细胞介素(interleukin,IL)-23 /辅助T细胞(helper T cells,Th)17途径已被确定为关键轴,促炎细胞因子IL-17A是其主要作用因子。有研究表明,银屑病患者血清中免疫球蛋白(immune globulin,Ig)E浓度增加。与非病变皮肤相比,病变皮肤有更多的特异性IgE的Fc段高亲和力受体I (receptor I for the Fc region of IgE,FceRI)相关细胞,包括肥大细胞,表皮树突状细胞,朗格汉斯细胞和巨噬细胞,现就银屑病发病机制中IL-17关键轴与IgE的相互作用进行综述。展开更多
