| lymphocyte function associated antigen | A member of the integrin family that is expressed on all leukocytes and binds to ICAM-1 and ICAM-2 on a variety of cells. (05 Mar 2000) |
|---|---|
| lymphocyte function-associated antigen-1 | A heterodimer molecule widely expressed on cells of haematopoietic origin. Cd11a antigen comprises the alpha chain and the CD18 antigen (antigens, CD18) the beta chain. Lfa-1 is a major receptor of T-cells, B-cells, and granulocytes. It mediates the leukocyte adhesion reactions underlying cytolytic conjugate formation, helper T-cell interactions, and antibody-dependent killing by natural killer cells and granulocytes. Intracellular adhesion molecule-1 (icam-1) has been defined as a ligand for lfa-1. (12 Dec 1998) |
| lymphogranuloma venereum antigen | A sterile preparation of inactivated chlamydiae grown in the yolk sac of domestic fowl and used as an antigen in the Frei test. (05 Mar 2000) |
| Lyt antigen | A set of plasmalemmal surface glycoproteins on mouse T lymphocytes. Possession of Lyt 1 partly defines a T helper cell and of Lyt 2, 3 suppressor and cytotoxic cells. Formerly known as Ly antigens. See: Lyb antigen. (18 Nov 1997) |
