益生菌 Escherichia coli Nissle1917功能研究进展. 大肠埃希菌Nissle1917，简称EcN，是益生菌中为数不多的革兰氏阴性菌，在临床上主要用于克罗恩病、溃疡性结肠炎等胃肠功能障碍。. 其机制在于EcN能在人体肠道定殖，并阻止病原菌对肠道黏膜的侵袭，对肠道黏膜屏障

OBJECTIVES Different probiotic strains used in clinical trials have shown prophylactic properties in different inflammatory diseases of the gastrointestinal tract. This study was aimed to investigate the influence of Escherichia coli strain Nissle 1917 (EcN) components on the integrity of the Caco-2 cell monolayer (human adenocarcinoma cell line).
Escherichia coli Nissle 1917 (EcN) has been proven to be operative for curing the inflammatory intestinal illnesses [ 16 – 18] and acute diarrhea [ 19 ]. EcN is a nonpathogenic gram-negative strain utilized in numerous gastrointestinal issues consisting of diarrhea [ 20 ], uncomplicated diverticular malady [ 21] and IBD, specifically UC [ 22 ].

In this study, probiotic facultative anaerobe Escherichia coli Nissle 1917 (EcN) was functionalized and formed self-propelled microrobots to actively deliver therapeutic drug and photosensitizer to the deep hypoxic regions of tumors.

Probiotic bacteria like E. coli Nissle 1917 (EcN), Lactobacillus species, Streptococcus species, and Bifidobacterium species work to boost the immune system either individually or in combination with other probiotic strains. Probiotics biofilm presence in a healthy gut promotes nutrient exchange between the host and microbiota, and it increases . 476 452 194 377 33 159 491 43
