The expression of several receptors that are shown in literature to recognize HMOs were measured on A) monocytes and B-G) moDC, TGFβDC and vitD3DC. The expression of Siglec-5, Siglec-7, TLR4, CD206, Galactin-3 and DC-SIGN (open histograms) and their matching isotype control (shaded histograms) were measured on monocytes. The expression of B) CD206, C) DC-SIGN, D) Siglec-5, E) TLR4, F) Galactin-3 and G) Siglec-7 was shown by scatter plots (n = 3–5) and histogram of one representative donor. Normal distribution was assumed due to the low sample size. Significance was tested by a repeated measures ANOVA with a Tukey’s multiple comparison post-hoc test.
