2’-Fucosyllactose alleviate immune checkpoint blockade-associated colitis by reshaping gut microbiota and activating AHR pathway by Shikai Yan, Leilei Yu, Fengwei Tian, Jianxin Zhao, Wei Chen, Qixiao Zhai

“…In addition, administration of 2’FL increased the abundance of Bifidobacterium and Lactobacillus, and elevated the levels of microbial metabolites, such as indole-3-lactic acid (ILA), which activated the aryl hydrocarbon receptor ligands (AHR) pathway. The protective effect of 2’FL was abolished upon depletion of gut microbiota, and ILA treatment partially simulated the protective effect of 2’FL. …”

Microbial metabolites and immune modulation by Hassan Ghasemi

“…These interactions regulate inflammation by modulating the production of pro-inflammatory cytokines and altering dendritic cell activity, which is critical for antigen presentation and immune tolerance.7 The microbial metabolism of tryptophan, an essential amino acid derived from dietary proteins, results in the production of indole derivatives that activate the aryl hydrocarbon receptor (AhR). This receptor is pivotal in maintaining intestinal homeostasis, regulating barrier function, and promoting mucosal immunity. …”
