Rövid összefoglaló (regiszter, angolul)

Through a series of studies,the investigators has discovered for the first time that gut microbiota-derived DL-endopeptidase is a core regulator of the NOD2 pathway. This research also reveals a novel etiological mechanism in which deficiency of gut bacterial DL-endopeptidase leads to dysfunctional NOD2 signaling, thereby promoting the pathogenesis of inflammatory bowel disease (IBD).( The findings have been published in Cell Host \& Microbe and Nature Communications.) Based on this, the investigators has successfully screened a high DL-endopeptidase-producing active strain, Lactobacillus rhamnosus CALM 607 (abbreviated as LR607), from the traditional probiotic Lactobacillus rhamnosus.(Its unique advantages include: 1) Independent intellectual property rights (patent applied for);2) DL-endopeptidase production and NOD2 regulatory ability 2.7 times higher than that of the conventional strain LGG;3) Preclinical experiments have demonstrated its potential to alleviate intestinal inflammation.) The investigators' Phase I clinical trial (data pending publication) has confirmed that LR607 has good safety and tolerability in healthy volunteers, providing a safety foundation for subsequent clinical studies. Therefore, the investigators aim to investigate the DL-endopeptidase-producing probiotic LR607 through randomized controlled clinical intervention studies, to evaluate its adverse effects in adjunctive therapy and comprehensively assess its impact on the gut microbiome-NOD2 pathway, intestinal inflammation, and the progression of IBD.
