Circulating adhesion molecules in sera of asthmatic children
Abstract
Infiltration of cells into the lung in asthma is regulated by several expressions of cell adhesion molecules (CAMs) on cells present in the airways, and may play a role in the pathogenesis of bronchial asthma. We sought to evaluate the role of serum concentrations of the soluble forms of intercellular adhesion molecule-1 (sICAM-1), vascular cell adhesion molecule-1 (sVCAM-1), and E-selectin (sE-selectin) in the control of disease activity in acute asthma. Circulating levels of sICAM-1, sVCAM-1, and sE-selectin in sera from 15 normal control subjects and from 20 allergic asthmatic children with acute exacerbations who had returned to stable condition were determined by using commercially available enzyme-linked immunosorbent assay kits. The mean concentration of serum sICAM-1 levels was significantly higher during an acute exacerbation of asthmatic children than in those with stable asthma (19.41 +/- 10.65 ng/mL vs. 13.46 +/- 5.44 ng/mL; P < 0.001) or in control subjects (9.83 +/- 2.02 ng/mL; P < 0.001). For sVCAM-1 and sE-selectin, the mean serum concentration of sVCAM-1 was slightly higher in children during an acute exacerbation asthma than when stable. However, the differences did not reach statistical significance. The mean...Continue Reading

Allergy and Asthma
Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
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. Discover the latest research on adhesion molecule and their role in health and disease here.
Asthma
This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
