Abstract

There is the whole proteins family, localized on cellular surfaces and regulating lymphocyte-endoteliocyte interaction process, called ekto-peptides. VAP-1 (vascular adhesive protein-1) also belongs to it. Human VAP-1 is the dimeric membrane protein with molecular weight of 180 kD consisting of short N-trailer cytoplasmatic tail, transmembrane domain and most extracellular part. VAP-1 stimulates lymphocytes rolling, adhesion and transmigration through endothelial vessels lining, and also polymorphic and nuclear leukocytes. During studying of VAP-1 expression in kidneys, it is found in peritubular capillaries and perithelial cells of the, and also in smooth muscle cells of larger vessels. Almost completely absent is VAP-1 expression in glomerular endothelial cells.Further studying of signal VAP-1-mediated pathway influence on glomerulonephritis course and outcomes will provide to expand ideas of disease pathogenesis and new influence ways on chronic kidney disease progressing.
