The glycoprotein P-selectin belongs to the selectin family of cell adhesion molecules. In this study, we cloned the full-length cDNA of P-selectin from zebrafish (Danio rerio) by the method of rapid amplification of cDNA ends polymerase chain reaction (RACE-PCR). Zebrafish P-selectin cDNA is 2,800 bp and encodes a putative 868 amino acid protein with a theoretical molecular weight of 122.36 kDa...

ate like James Bond, in thrilling ways, but under obscure Computational Modeling of Genetic and acronyms that confound the novice reader. Chapter 8 Biochemical Networks begins with an overview of how armies of leukocytes Edited By James M.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by loss of tolerance toward self-nucleic acids, autoantibody production, interferon expression and signaling, defect in the regulatory T (T reg ) cell compartment. In this work, we identified that platelets from patients with active SLE preferentially interacted cells via P-selectin/P-selectin glycoprotein ligand-...

Neutrophil accumulation at sites of inflammation is mediated by specific groups of cell adhesion molecules including the b2 (CD18) integrins on leukocytes and the selectins (Pand E-selectin on the endothelium and L-selectin on the leukocyte). This is supported by studies of patients with leukocyte adhesion deficiency syndromes whose leukocytes are genetically deficient in the expression of b2 i...

Leukocyte migration from the blood into tissues is pivotal in immune homeostasis and in inflammation. During the multistep extravasation cascade, endothelial selectins (P- and E-selectin) and vascular adhesion protein-1 (VAP-1), a cell-surface-expressed oxidase, are important in tethering and rolling. Here, we studied the signaling functions of the catalytic activity of VAP-1. Using human endot...

The selectins are transmembrane, Ca(2+)-dependent lectins that mediate leucocyte rolling on vascular surfaces, the first adhesive step during inflammation and immune surveillance. Leucocytes express L-selectin, activated platelets express P-selectin, and activated endothelial cells express E- and P-selectin. Rolling involves force-regulated, rapidly reversible interactions of selectins with a l...

he colonization of the liver by colorectal cancer (CRC) cells is a complicated process which includes many stages, until macrometastases occur. The entrapment of malignant cells within the hepatic sinusoids and their interactions with resident non-parenchymal cells are considered very important for the whole metastatic sequence. In the sinusoids, cell connection and signalling is mediated by mu...

OBJECTIVES The pathogenesis of Behçet's disease (BD) is closely related to endothelial cells, leucocyte functions and autoimmunity. The aim of this study was to investigate circulating selectin adhesion molecules, which are known to play a significant part in the immune response especially by regulating interactions of the leucocytes with endothelium, in BD. METHODS Plasma E-, L-, and P-selec...
