Background: ICAM-1/CD54

ICAM-1 (intercellular adhesion molecule-1), also known as CD54, is a transmembrane cell adhesion glycoprotein and a member of the immunoglobulin supergene family. The ICAM sub-family consists of five members, ICAM-1 through ICAM-5, and they vary in their tissue expression and number of Ig-like domains in the extracellular domain (ECD). Full-length ICAM-1 contains 5 Ig-like domains in the ECD, a single transmembrane domain and short intracellular domain. Alternative splicing of ICAM-1 results in at least six membrane-bound forms and one soluble form (1). The ECD of mature, full-length mouse ICAM-1 shares 78% and 54% amino acid sequence identity with rat and human ICAM-1, respectively. ICAM-1 plays an important role in both innate and adaptive immune responses and is up-regulated on endothelial and epithelial cells at sites of inflammation (2, 3). ICAM-1 mediates the vascular adhesion and paracellular migration of leukocytes expressing activated LFA-1 (CD11a/CD18) and Mac-1 (CD11b/CD18) (2, 3). It also binds several non-integrin ligands including CD43/Sialophorin, Fibrinogen, Hyaluronan, rhinoviruses, and Plasmodium falciparum-infected erythrocytes (4-8). Soluble ICAM-1 promotes angiogenesis and serves an indicator of vascular endothelial cell activation or damage (9). Elevated levels of soluble ICAM-1 are associated with cardiovascular disease, type 2 diabetes, organ transplant dysfunction, oxidant stress, increased abdominal fat mass, hypertension, liver disease, certain malignancies, and cerebral malaria (10-18). More recently, ICAM-1 was shown to be a novel regulator of group 2 innate lymphoid cells (ILC2s) which play a key role in allergic airway inflammation (19).
