The interaction between the E-rosette receptor (CD2) expressed on the cell surface of T lymphocytes and its natural ligand CD58 (LFA-3), a broadly distributed cell surface molecule, represents a potential target for immune modulation. To explore this possibility, we have expressed a soluble recombinant form of human CD58 which exerts potent biological effects in that it acts as a competitive inhibitor for cell surface CD58 in its binding to CD2 positive lymphocytes. Thus, recombinant CD58 blocks NK-mediated cytotoxicity, the mixed lymphocyte reaction, and the T lymphocyte adhesion to CD58 positive cells. In contrast, recombinant CD58 synergized with mitogenic CD2R monoclonal antibodies (anti-T11(2/3) or 9.1) in T cell triggering.

UI MeSH Term Description Entries
D007694 Killer Cells, Natural Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

Specific protein-binding measures are often used as assays in diagnostic assessments. Plasma Protein Binding Capacity,Binding, Protein
D011971 Receptors, Immunologic Cell surface molecules on cells of the immune system that specifically bind surface molecules or messenger molecules and trigger changes in the behavior of cells. Although these receptors were first identified in the immune system, many have important functions elsewhere.

D000276 Adjuvants, Immunologic Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.
