The intercellular adhesion molecule (ICAM) family of proteins. New members and novel functions

Macromolecular adhesive associations between cells are important for transmitting spatial and temporal information that is critical for immune system function. One such group of proteins, the intercellular adhesion molecules (ICAMs), has grown as newly identified members are revealed. In addition, the functions of the ICAMs, in general, have begun to be better understood, including intracellular signaling events. This information has led to the design of novel therapeutic agents that may prove effective in a variety of disease states.
