'''Intercellular adhesion molecule''' (ICAM) is part of the immunoglobulin superfamily. ICAM binds to leukocyte function associated molecule 1 (LFA-1) and macrophage-1 antigen during inflammation<ref>PMID:8834767</ref>. ICAM contains 5 Ig-like domains. | '''Intercellular adhesion molecule''' (ICAM) is part of the immunoglobulin superfamily.

*'''ICAM-1''' is Ig-like cell adhesion molecule which has a role in inflammatory processes and in T-cell mediated host defines system. | |||
*'''ICAM-2''' mediates adhesive interactions important for antigen-specific immune response. | |||
*'''ICAM-3''' acts as recognition receptor in the phagocytosis of macrophages in engulfment of apoptotic neutrophils<ref>PMID:23775590</ref>. | |||
*'''ICAM-5''' has 2 types of binding activities: binding between neutrons and binding between neuron and leukocytes. | |||
