Intercellular adhesion molecule-1 is a cell surface receptor for hyaluronan

Abstract

Our laboratory has previously characterized and purified the hyaluronan receptor by hyaluronan affinity chromatography of rat liver endothelial cells. We have now isolated the receptor from whole rat liver and have obtained sufficient quantities for amino acid sequence analysis. Four peptides of various lengths were obtained from affinity-purified receptor and found to have identity with rat intercellular adhesion molecule-1. This glycoprotein is normally expressed in low amounts on the endothelial cells, but is up-regulated in inflamed and malignant tissues, and mediates cell-cell adhesion as a ligand for lymphocyte function-associated antigen-1 and the macrophage-associated Mac-1. The affinity of intercellular adhesion molecule-1 for hyaluronan is likely to have important implications for cell adhesion in normal and in disease states such as inflammation, atherosclerosis, and cancer.

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.
