Abstract

Leukocyte activation, adhesion, and emigration serve a protective role during a well-contained inflammatory response. However, under certain pathologic conditions such as endotoxemia, inflammatory bowel disease, and ischemia-reperfusion injury, leukocytes may turn against the host and aggravate--rather than prevent--tissue damage. Numerous experimental studies have been performed during the last decade to investigate the pathophysiologic role of leukocyte accumulation and adhesion during ischemia/reperfusion injury of various organs, in particular of the myocardium. Most of the latter studies investigated whether the consequences of experimental myocardial infarction could be attenuated by interventions aimed at the inhibition of chemotactic leukocyte infiltration or adhesion (or both) to microvascular endothelial cells. Although many promising results were reported, the consequent step towards an introduction of these strategies into experimental or even routine clinical management of patients with myocardial infarction has so far not been undertaken. In this manuscript, the authors try to give an overview on the state of the art of "antileukocyte" strategies in myocardial ischemia-reperfusion injury and to offer explanations ...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.
