Adhesion molecules in cell interactions.

Author information

Imperial Cancer Research Fund, London, UK.


During a successful immune response, several families of adhesion molecules participate in a cascade of binding events that lead to the binding of leukocytes, both to each other and to cell types such as the endothelium and epithelium. A central theme emerging from recent studies is that the function of an adhesion receptor cannot be inferred from its expression alone; rather, adhesion receptors are 'selected' to perform distinct effector functions based on their cell-background and factors present in the local microenvironment. Thus, adhesion receptors expressed on different cell-types may find themselves in different states of 'activation-readiness' and may be further selected by prevailing conditions in the microenvironment to bind tissue-specific ligands and mediate leukocyte effector functions such as homing or transendothelial migration.
