Two classes of adhesion molecules have well-defined roles in the attachment of unstimulated polymorphonuclear leukocytes (PMN) to cytokine-treated endothelial cells. Endothelial-leukocyte adhesion molecule 1(ELAM-1) on endothelial cells interacts with specific carbohydrate residues on the PMN, and the leukocyte integrins (CD18 antigens) on PMN interact with intracellular adhesion molecule 1 and...

This study examines the role of endothelial leukocyte adhesion molecule-1 (ELAM-1) in the development of the acute airway inflammation (cell influx) and late-phase airway obstruction in a primate model of extrinsic asthma. In animals sensitive to antigen, a single inhalation exposure induced the rapid expression of ELAM-1 (6 h) exclusively on vascular endothelium that correlated with the influx...

The carbohydrate antigen, sialyl Lex, is known to be a ligand for the cell adhesion molecule called ELAM-1 (E-selectin, endothelial cell leukocyte adhesion molecule-1), which is present on cytokine-activated human endothelial cells. Recently, we reported that another carbohydrate antigen, sialyl Lea, can also serve as a ligand for ELAM-1 (A. Takada, K. Ohmori, N. Takahashi, K. Tsuyuoka, K. Yago...

Neutrophil adhesion to interleukin-1 (IL-1)-stimulated human umbilical vein endothelial cells (HUVEC) involves the CD18 family of leukocyte integrins (lymphocyte function-associated antigen-1 [LFA-11, Mac-1, and ~150.95) and LECAM-1 (DREG-56/LEU-8/LAM-l antigen) on neutrophils and intercellular adhesion molecule-l (ICAM-l) and endothelial leukocyte adhesion molecule-1 (ELAM-1) on the endotheliu...

The clinical complications associated with severe and cerebral malaria occur as a result of the intravascular mechanical obstruction of erythrocytes infected with the asexual stages of the parasite, Plasmodium falciparum. We now report that a primary P. falciparum-infected erythrocyte (parasitized red blood cell [PRBC]) isolate from a patient with severe complicated malaria binds to cytokine-in...

Pretreatment of endothelial cells with cytokines enhances the adherence of leukocytes, a process that is mediated by surface proteins expressed on both cell types. A three-dimensional model system for the simultaneous determination of leukocyte adherence and migration was used to study the contribution of CD11/CD18, endothelial leukocyte-adhesion molecule-1 (ELAM-1) and VLA-4 in neutrophil and ...

PURPOSE To explore whether geographic mobility is associated with career advancement of women in U.S. medical schools who are entering mid- to executive-level positions. METHOD Using an existing dataset of 351 participants in academic medicine who attended the Executive Leadership in Academic Medicine (ELAM) Program for Women (1996-2005) (adjusted to 345 participants in some analyses because ...

based on the historical data, marhashi has been one of the eventful regions of iran during the second and third millennium b. c. it has been also one of the important confederates of ancient elam during the most of its life time. the mesopotamia texts cited to its name beside the name of ancient elam. the goal of this research is to determine the position of marhashi region through study and ex...

To understand the molecular events which are important in leucocyte trafficking in cutaneous inflammation, poison ivy/oak extract was applied topically to the skin, and the simultaneous assessment of a variety of clinical and immunopathological parameters performed. The clinical response of subjects was divided into three main groups: I, 2-24h after application, before the onset of erythema; II...

Interaction of leucocytes with human corneal endothelial cells (HCECs) can be observed in several clinicopathological conditions, such as uveitis, keratitis, and corneal graft rejection. Since leucocyte-endothelial cell interactions involve various adhesion receptors we have analysed the expression and distribution pattern of the neural cell adhesion molecule (NCAM), the intercellular adhesion ...
