Inflammatory bowel diseases (IBD) are characterized by wasting and chronic intestinal inflammation triggered by various cytokine-mediated pathways. In recent years, it was shown that T helper 17 (Th17) cells are involved in the pathogenesis of IBD, which makes them an attractive therapeutic target. Th17 cells preferentially produce interleukin (IL)-17A-F as signature cytokines. The role of the interplay between host genetics and intestinal microbiota in the pathogenesis of IBD was demonstrated. Probiotics are live microorganisms that when orally ingested in adequate amounts, confer a health benefit to the host by modulating the enteric flora or by stimulating the local immune system. Several studies indicated the effectiveness of probiotics in preventing and treating IBD (ulcerative colitis, and Crohn's disease). Furthermore, there is mounting evidence of probiotics selectively targeting the Th17 lineage in the prevention and management of inflammatory and autoimmune diseases such as IBD. This review highlights critical roles of Th17 cells in the pathogenesis of IBD and the rationale for using probiotics as a novel therapeutic approach for IBD through manipulation of Th17 cells. The potential molecular mechanisms by which probiotics modulate Th17 cells differentiation and production are also discussed.
炎症性肠病(IBD)的特征是由各种细胞因子介导的途径引发的消瘦和慢性肠道炎症。近年来,研究表明辅助性T细胞17(Th17)参与了IBD的发病机制,这使其成为一个有吸引力的治疗靶点。Th17细胞优先产生白细胞介素(IL)-17A-F作为标志性细胞因子。宿主遗传学和肠道微生物群之间的相互作用在IBD发病机制中的作用已得到证实。益生菌是活的微生物,当适量口服时,可通过调节肠道菌群或刺激局部免疫系统为宿主带来健康益处。多项研究表明益生菌在预防和治疗IBD(溃疡性结肠炎和克罗恩病)方面具有有效性。此外,越来越多的证据表明,益生菌在预防和管理IBD等炎症性和自身免疫性疾病中选择性地靶向Th17谱系。本综述强调了Th17细胞在IBD发病机制中的关键作用,以及通过操纵Th17细胞将益生菌用作IBD新型治疗方法的基本原理。还讨论了益生菌调节Th17细胞分化和产生的潜在分子机制。
