Inducible cell adhesion molecule 110 (INCAM-110) is a 110-kD glycoprotein expressed on cytokine-activated human vascular endothelial cells. mAb blocking studies indicate that INCAM-110 and intercellular adhesion molecule 1 (ICAM-1) independently support the adhesion of lymphocytes to activated human umbilical vein endothelial cell monolayers.(More)
Inducible cell adhesion molecule 110 (INCAM-110), is a 110-kd adhesion receptor for lymphocytes and monocytes identified on cytokine-activated endothelium. Using immunoperoxidase techniques, little or no INCAM-110 was detected on endothelium in normal human tissues. In contrast, INCAM-110 was expressed in postcapillary venules in a variety of active(More)
Current concepts of the pathogenesis of atherosclerosis have been reviewed, emphasizing some of the similarities of the mechanisms and events involved to those in inflammation. Figure 2 is a schematic summary of these events. Hyperlipidemia, or some component of hyperlipidemic serum, as well as other risk factors, are thought to cause endothelial injury,(More)
Recombinant human interferon (IFN)-gamma (2 X 10(4) or 2 X 10(5) U), tumor necrosis factor (TNF, 10(4) or 10(5) U), or both were injected intracutaneously into baboons (Papio anubis), and biopsies were examined at various intervals for evidence of altered endothelial cell antigen expression, endothelial morphology, and leukocyte infiltration. IFN-gamma(More)
Endothelium is central to the cellular infiltration that develops during inflammation, and a prominent feature of its involvement is the expression of adhesion molecules for circulating leukocytes. In the present study, we assessed the kinetics of endothelial adhesion molecule expression during the cutaneous endotoxin response in baboons. Immunostained(More)
Human B lymphocytes localize and differentiate within the microenvironment of lymphoid germinal centers. A frozen section binding assay was developed for the identification of those molecules involved in the adhesive interactions between B cells and lymphoid follicles. Activated human B cells and B cell lines were found to selectively adhere to germinal(More)
Cell-mediated immune reactions are initiated and regulated by antigen specific CD4+ helper T cells. However, T cells cannot function independently. In order for a CD4+ T cell to recognize antigen, it must be presented in association with a class II major histocompatibility complex molecule by another cell type and, in order to lead to functional T-cell(More)
The carbohydrate structure sialyl-Lewis X (SLex) can function as a ligand for E-selectin, formerly known as endothelial leukocyte adhesion molecule-1 (ELAM-1). This study was performed to analyze the expression of SLex by leukocytes and other cell types in the context of inflammatory and immune processes. Human peripheral blood cells were examined by flow(More)
In germinal centers, B lymphocytes are intimately associated with follicular dendritic cells (FDCs). It has been hypothesized that FDCs are involved in the regulation of B-cell growth and differentiation through cell-cell interactions. In this study, highly enriched preparations of FDCs were isolated by cell sorting using the FDC restricted monoclonal(More)
Follicular lymphomas recapitulate the architecture of germinal centers (GCs) of normal secondary lymphoid follicles. Using an in vitro binding assay, it has recently been demonstrated that the normal B lymphocytes bind to GCs. This interaction is mediated by a receptor-ligand pair consisting of the beta 1 integrin very late antigen 4 (VLA-4) on the B cell,(More)
