<unk>  <unk>  is an integrin found on<unk> s and other leukocytes.<unk>  plays a key role in emigration, which is the process by which leukocytes leave the bloodstream to enter the tissues.<unk>  also mediates firm arrest of leukocytes. Additionally,<unk>  is involved in the process of cytotoxic T cell mediated killing as well as antibody mediated killing by granulocytes and monocytes. As of 2007,<unk>  has 6 known ligands: ICAM-1, ICAM-2, ICAM-3, ICAM-4, ICAM-5, and JAM-A.<unk> /ICAM-1 interactions have recently been shown to stimulate signaling pathways that influence T cell differentiation.<unk>  belongs to the integrin superfamily of adhesion molecules.
