Sulforaphene (LFS-01) is a natural compound derived from traditional herbal medicine. Here, we show that oral administration of LFS-01 is able to dramatically alter the skewed gut microbiota and reverse colitis in model mice associated with an increase of intestinal γδT cells. Through 16S rDNA sequencing, we showed that LFS-01 can selectively suppress enteric pathogens such as and whereas the protective strains including and were significantly expanded after LFS-01 treatment. Interestingly, we demonstrated that LFS-01 administration can significantly promote the IL-17+γδT cells in model mice in response to the expanded . We verified that the intracellular components of can stimulate the growth of IL-17+γδT cells upon preincubation. The increased IL-17A after LFS-01 treatment in turn recovers the disrupted occludin subcellular location and protects the epithelial barrier in the colon of model mice. Remarkably, LFS-01 does not show apparent toxicity to animals and we demonstrated that LFS-01 also exerts strong protective effects in TNBS-induced colitis rats. Therefore, LFS-01 holds great promise for the treatment of inflammatory bowel disease (IBD) and warrants translation for use in clinical trials. Our work provided a new avenue for the treatment of IBD based on the strategy of harnessing intestinal symbiosis.
萝卜硫素(LFS - 01)是一种源自传统草药的天然化合物。在此,我们表明口服LFS - 01能够显著改变模型小鼠中失衡的肠道微生物群,并逆转与肠道γδT细胞增加相关的结肠炎。通过16S rDNA测序,我们发现LFS - 01可以选择性抑制诸如[具体病原体1]和[具体病原体2]等肠道病原体,而包括[具体有益菌1]和[具体有益菌2]在内的保护性菌株在LFS - 01处理后显著增加。有趣的是,我们证明给予LFS - 01能够显著促进模型小鼠中IL - 17 + γδT细胞对扩增的[具体有益菌]的反应。我们证实,[具体有益菌]的细胞内成分在预孵育后能够刺激IL - 17 + γδT细胞的生长。LFS - 01处理后IL - 17A的增加反过来恢复了模型小鼠结肠中被破坏的闭合蛋白亚细胞定位,并保护了上皮屏障。值得注意的是,LFS - 01对动物未表现出明显毒性,并且我们证明LFS - 01在三硝基苯磺酸(TNBS)诱导的结肠炎大鼠中也发挥了强大的保护作用。因此,LFS - 01在治疗炎症性肠病(IBD)方面具有巨大潜力,值得转化用于临床试验。我们的工作为基于利用肠道共生策略治疗IBD提供了一条新途径。
