Lymphocyte function-associated antigen 1

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