N-acetylglucosamine-6-O-sulfotransferases 1 and 2 cooperatively control lymphocyte homing through L-selectin ligand biosynthesis in high endothelial venules.
Kawashima H., Petryniak B., Hiraoka N., Mitoma J., Huckaby V., Nakayama J., Uchimura K., Kadomatsu K., Muramatsu T., Lowe J.B., Fukuda M.
Lymphocyte homing is mediated by specific interactions between L-selectin on lymphocytes and sulfated carbohydrates restricted to high endothelial venules in lymph nodes. Here we generated mice deficient in both N-acetylglucosamine-6-O-sulfotransferase 1 (GlcNAc6ST-1) and GlcNAc6ST-2 and found tha ... >> More
Lymphocyte homing is mediated by specific interactions between L-selectin on lymphocytes and sulfated carbohydrates restricted to high endothelial venules in lymph nodes. Here we generated mice deficient in both N-acetylglucosamine-6-O-sulfotransferase 1 (GlcNAc6ST-1) and GlcNAc6ST-2 and found that mutant mice had approximately 75% less homing of lymphocytes to the peripheral lymph nodes than did wild-type mice. Consequently, these mice had lower contact hypersensitivity responses than those of wild-type mice. Carbohydrate structural analysis showed that 6-sulfo sialyl Lewis X, a dominant ligand for L-selectin, was almost completely absent from the high endothelial venules of these mutant mice, whereas the amount of unsulfated sialyl Lewis X was much greater. These results demonstrate the essential function of GlcNAc6ST-1 and GlcNAc6ST-2 in L-selectin ligand biosynthesis in high endothelial venules and their importance in immune surveillance. << Less

L-selectin mediates lymphocyte homing by facilitating lymphocyte adhesion to addressins expressed in the high endothelial venules (HEV) of secondary lymphoid organs. Peripheral node addressin recognized by the MECA-79 antibody is apparently part of the L-selectin ligand, but its chemical nature has been undefined. We now identify a sulfated extended core1 mucin-type O-glycan, Gal beta 1-->4(sulfo-->6)GlcNAc beta 1-->3Gal beta 1-->3GalNAc, as the MECA-79 epitope. Molecular cloning of a HEV-expressed core1-beta 1,3-N-acetylglucosaminyltransferase (Core1-beta 3GlcNAcT) enabled the construction of the 6-sulfo sialyl Lewis x on extended core1 O-glycans, recapitulating the potent L-selectin-mediated, shear-dependent adhesion observed with novel L-selectin ligands derived from core2 beta1,6-N-acetylglucosaminyltransferase-I null mice. These results identify Core1-beta 3GlcNAcT and its cognate extended core1 O-glycans as essential participants in the expression of the MECA-79-positive, HEV-specific L-selectin ligands required for lymphocyte homing. << Less
