Circulating selectin- and immunoglobulin-type adhesion molecules in acute ischemic stroke
Abstract
Cellular adhesion molecules mediate adhesion between endothelial cells and leukocytes as a precondition for extravasation of leukocytes at sites of tissue injury. The pattern of release of circulating adhesion molecules has been characterized in patients with acute ischemic stroke. Serum concentrations of soluble selectin-type adhesion molecules (solube endothelial leukocyte adhesion molecule-1 [sELAM-1], soluble lymph node homing receptor [sL-selectin]) and immunoglobulin-type adhesion molecules (soluble vascular cell adhesion molecule-1 [sVCAM-1], soluble intercellular adhesion molecule-1 [sICAM-1]) were serially determined (at hours 4, 8, and 10 and at days 1, 3, and 5) in 22 patients with acute ischemic stroke. As control subjects, age- and sex-matched individuals with (n = 40) and without (n = 22) vascular risk factors were studied. We observed increased concentrations of sICAM-1 and decreased levels of sL-selectin in patients with risk factors even in the absence of stroke. Patients with acute stroke had, in addition, an initial transient increase of sELAM-1 and a persistent increase of sVCAM-1. The results suggest a chronic alteration of expression of adhesion molecules sICAM-1 and sL-selectin in subjects with risk facto...Continue Reading

Adhesion Molecules in Health and Disease
Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
