LFA-1 was originally described as CTL-specific accessory molecule, critically important in CTL-mediated cytotoxicity (Davignon et al., 1981; Sanchez-Madrid et al., 1982). In accordance, LFA-1-deficient mice show impaired activity of peripheral cytotoxic T cells and reduced antitumor immunity (Schmits et al., 1996).

1 Importantly, integrins have the ability to modulate their adhesive properties within seconds after chemokine stimulation. 11 We and others have previously shown that TCR activation, chemokines, and ligands to LFA-1 regulate α 4 β 1 … LFA-1 (lymphocyte function-associated antigen-1) plays a role in intercellular adhesion and lymphocyte trafficking and activation and is an attractive anti-inflammatory drug target. The alpha-subunit of LFA-1, in common with several other integrins, has an N-terminally inserted domain (I-domain) of approximately 200 amino acids that plays a central role in regulating ligand binding to LFA-1 The lymphocyte function-associated antigen-1 (LFA-1) (also known as CD11a/CD18 and αLβ2), is just one of many integrins in the human body, but its significance is derived from its exclusive presence in leukocytes. In this review, we summarize the studies relating LFA-1 and its major ligand ICAM-1 (or CD54) with cancer, through the function of lymphocytes and myeloid cells on tumor cells. The LFA-1 antagonist, BIRT377, similarly reverses allodynia in males and females. Mice were either sham or treated with perisciatic 5-0 suture. (A) All groups of mice show similar BL threshold hindpaw sensitivity.

The LFA-1 integrin is known to mediate adhesion between T cells and antigen-presenting cells. New evidence, however, is provided for its role in transmitting signals that promote T cell activation In order for LFA-1 to bind to ICAM1, LFA-1 must be activated to a high affinity state, a process which can be imaged via radiolabeled DANBIRT [33]. 3D autoradiography was implemented in the study to allow both functional and advanced anatomical assessment of the presence of LFA-1 expression in cardiovascular tissues.

Lymphocyte stoppage on dendritic cells (DC) requires activation of LFA-1 by T cell receptor (TCR) signals, but the molecular basis of this activation is elusive.

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. Additionally, LFA-1 is involved in the process of cytotoxic T cell mediated killing as well as antibody mediated killing by granulocytes and monocytes.
