E-selectin receptors on human leukocytes.

Selectins on activated vascular endothelium mediate inflammation by binding to complementary carbohydrates on circulating neutrophils. The human neutrophil receptor for E-selectin has not been established. We report here that sialylated glycosphingolipids with 5 N-acetyllactosamine (LacNAc, Galbeta1-4GlcNAcbeta1-3) repeats and 2 to 3 fucose residues are major functional E-selectin receptors on human neutrophils.
