Title
Sweet preferences of MGL: carbohydrate specificity and function.
Affiliation
Department of Molecular Cell Biology and Immunology, VU University MedicalCenter, Amsterdam, The Netherlands.
Abstract
C-type lectins play important roles in both innate and adaptive immuneresponses. In contrast to the mannose- or fucose-specific C-type lectins DC-SIGNand mannose receptor, the galactose-type lectins, of which only macrophagegalactose-type lectin (MGL) is found within the immune system, are less wellknown. MGL is selectively expressed by immature dendritic cells and macrophageswith elevated levels on tolerogenic or alternatively activated subsets. HumanMGL has an exclusive specificity for rare terminal GalNAc structures, which arerevealed on the tumor-associated mucin MUC1 and CD45 on effector T cells. Thesefindings implicate MGL in the homeostatic control of adaptive immunity. Wediscuss here the functional similarities and differences between MGL orthologsand compare MGL to its closest homolog, the liver-specific asialoglycoproteinreceptor (ASGP-R).
