研究目的:

1)明确补充FN041缓解儿童湿疹的效果。 2)揭示FN041在小肠产生吲哚-3-乳酸,通过wnt通路激活肠上皮细胞和树突细胞视黄醇代谢,促进肠系膜淋巴结调节性T细胞分化增殖,缓解湿疹的作用机理。  

Objectives of Study:

1) To demonstrate the effect of children consumption of Limosilactobacillus reuteri FN041 in alleviating eczema in children. 2) This study reveals that Limosilactobacillus reuteri FN041 produces indole-3-lactic acid in the small intestine, activates retinol metabolism in intestinal epithelial cells and dendritic cells through the wnt pathway, promotes the differentiation and proliferation of regulatory T cells in mesenteric lymph nodes, and alleviates eczema
