Lymphocyte trafficking to lymph nodes (LNs) is initiated by the interaction between lymphocyte L-selectin and certain sialomucins, collectively termed peripheral node addressin (PNAd), carrying specific carbohydrates expressed by LN high endothelial venules (HEVs). Here, we identified a novel HEV-associated sialomucin, nepmucin (mucin not expressed in(More)
After an inflammatory stimulus, lymphocyte migration into draining lymph nodes increases dramatically to facilitate the encounter of naive T cells with Ag-loaded dendritic cells. In this study, we show that CD73 (ecto-5'-nucleotidase) plays an important role in regulating this process. CD73 produces adenosine from AMP and is expressed on high endothelial(More)
Chemokines displayed on the luminal surface of blood vessels play pivotal roles in inflammatory and homeostatic leukocyte trafficking in vivo. However, the mechanisms underlying the functional regulation of chemokines on the endothelial cell surface remain ill-defined. A promiscuous chemokine receptor, the Duffy antigen receptor for chemokines (DARC), has(More)
