Abstract: | The adherence of neutrophils to the endothelium is a crucial early event in the inflammatory and immunological reaction. Neutrophil-endothelial cell interactions are known to be mediated by adhesion molecules that are expressed on each cell. Among the adhesion molecules expressed on leukocytes, the CD11/CD18 integrin family plays a major role in the adhesion and transendothelial migration of neutrophils. The two most extensively characterized endothelial cell adhesion molecules are intercellular adhesion molecule-1 and E-selectin. These adhesion molecules are involved in the pathogenesis of several digestive diseases such as Helicobacter pylori, non steroidal anti inflammatory drug- or stress-induced gastric mucosal injury, inflammatory bowel diseases. |
