Platelet adhesion to vascular endothelial cells is a pathophysiologically relevant cell-to-cell interaction. However, the mechanisms underlying this cellular interaction are incompletely understood. In search of the ligand for CD226 adhesion molecule expressed on platelets, we found that human umbilical vein endothelial cells (HUVEC) express significant amount of putative CD226 ligand. We demon...
Tumor necrosis factor-alpha, interleukin-1, and endotoxin stimulate the expression of vascular endothelial cell (EC) adhesion molecules. Here we describe a novel pathway of adhesion molecule induction that is independent of exogenous factors, but which is dependent on integrin signaling and cell-cell interactions. Cells plated onto gelatin, fibronectin, collagen or fibrinogen, or anti-integrin ...
Leukocyte migration across endothelial cell borders (paracellular) and through endothelial cells (transcellular) appear to be distinct processes. During paracellular migration, membrane from a parajunctional reticulum of interconnected vesicles, the endothelial lateral border recycling compartment (LBRC), moves to surround the leukocyte in a kinesin-mediated, microtubule-dependent manner. We sh...
Background: Atherosclerosis is a chronic inflammation that interferes with blood arteries functions due to the accumulation of low density lipids and cholesterol. Objective: To investigate the effect of aqueous extract and saponin fraction of Tribulus terrestris L. (TT) on the proteome and expression of intracellular adhesion molecule-1 (ICAM-1), vascu...
In sickle cell anemia (SCA), inflammatory (i.e., intravascular sickling and transient vasoocclusive) events result in chronic endothelial activation. In addition to sickling behavior, sickle (SS) red blood cells exhibit abnormal interaction with the vascular endothelium, which is considered to have an important role in initiation of vasoocclusion. Upregulation of endothelial adhesion molecules ...
Periodontitis is a response of highly vascularized tissues to the adjacent microflora of dental plaque. Progressive disease has been related to consortia of anaerobic bacteria, with the gram-negative organism Porphyromonas gingivalis particularly implicated. The gingipains, comprising a group of cysteine proteinases and associated hemagglutinin domains, are major virulence determinants of this ...
OBJECTIVE Beyond their eminent role in hemostasis and thrombosis, platelets are recognized as mediators of inflammation. Platelet cluster of differentiation 40 (CD40) ligand (CD40L and CD154) plays a key role in mediating platelet-induced inflammation in atherosclerosis. CD40, the receptor for CD40L, is present on platelets; however, the role of CD40 on this cell type is until now undefined. ...
