NIHMS782578-supplement-Supp_File_6.xlsx (75K) GUID:?5F84E5FB-19A5-4DC9-B294-DE857EF67799 Abstract Human milk glycans (HMGs) are prebiotics, pathogen receptor decoys, and regulators of host physiology and immune responses. Mechanistically, human lectins (glycan-binding proteins, hGBPs) expressed by dendritic cells (DC) are of major interest, as these cells directly contact HMGs. To explore such interactions, we screened many C-type lectins and Siglecs expressed by DC for glycan binding on microarrays presenting over 200 HMGs. Unexpectedly, DC-SIGN showed robust binding to many HMGs, whereas other C-type lectins failed Rabbit Polyclonal to Caspase 9 (phospho-Thr125)<\/a> to bind, and Siglecs-5 and -9 showed weak binding to a few glycans. By contrast, most hGBPs bound to multiple glycans on other microarrays lacking HMGs. An -linked fucose residue was characteristic of HMGs bound by DC-SIGN. Binding of DC-SIGN to the simple HMGs 2-fucosyllactose (2-FL) and 3-fucosyllactose (3-FL) was confirmed by circulation cytometry to beads conjugated with 2-FL or 3-FL, as well as the ability of the free glycans to inhibit DC-SIGN binding. 2-FL experienced an IC50 of ~1 mM for DC-SIGN, which is within the physiological concentration of 2-FL in human milk. These results demonstrate that DC-SIGN among the many hGBPs expressed by DC binds to -fucosylated HMGs, and suggest that such interactions may be important in influencing immune responses in the developing infant. are thus unclear. Unexpectedly, given the fact that sialic acid is usually a common residue in HMGs, the only Siglecs tested that showed some binding to HMGs were Siglecs-5 and -9 (Fig. 1), consistent with the possibility that glycan acknowledgement by Siglecs is usually complex and the presence of sialic acid is necessary but not sufficient in most cases. Siglec-5 binding was poor and only occurred at high Siglec-5 concentrations, Linagliptin (BI-1356) while Siglec-9 binding was stronger but binding to the free, underivatized HMGs 6-SL was still poor (Fig. 6). Instead, Siglec-9 bound strongly to 6-SL derivatized at the reducing end with an aglycone linker, AEAB and especially GGAEAB. This finding suggests that the aglycone element and\/or multivalent demonstration could be a key point in Siglec-9 and additional Siglecs for binding glycoconjugate ligands, or that particular sialylated glycans however to become identified are solid ligands for Siglecs. This locating from the potential importance the aglycone in Siglec binding could also clarify why the binding of Siglecs towards the CFG microarray with this study Linagliptin (BI-1356) includes a generally.<\/p>\n","protected":false},"excerpt":{"rendered":"
