Human milk oligosaccharide 2′-FL improves gut permeability during early NAFLD development. (A) Gut permeability measured by FITC-labeled dextran at an early (at t = 12 w) and late (at t = 27 w) time point of the disease process equaling 4 and 19 weeks of 2′-FL supplementation, respectively. (B) Plasma LPS-binding protein (LBP) measured in week 28 of the study. Data is from n = 18 mice per treatment group presented as mean ± SEM, *p < 0.05, ***p < 0.001 compared to HFD + vehicle. (C) Fecal microbiota composition was analyzed by 16S sequencing and composition changes over time were visualized by non-metric multidimensional scaling (NMDS) using the Bray-Curtis index. Every dot represents the microbiota composition of one mouse. A greater distance between dots indicates more dissimilarity. Blue arrows indicate 2′-FL induced microbiota composition shifts. (D) Fecal Bifidobacterium abundance over time.
