| muromonab-CD3 | <chemical> Anti-CD3 monoclonal antibody that exerts immunosuppressive effects by inducing peripheral T-cell depletion and modulation of the T-cell receptor complex (CD3/ti). This biochemically purified IgG immunoglobulin is obtained through the fusion of mouse myeloma cells to lymphocytes from immunised animals to produce hybridomas that secrete specific antibodies to the t3 (CD3) antigens of human T-lymphocytes. It is often used as an immunosuppressive agent in transplantation. Pharmacological action: immunosuppressive agents. (12 Dec 1998) |

| antigens, CD3 | <immunology> A complex of at least five membrane-bound polypeptides in mature T-lymphocytes that are non-covalently associated with one another and with the T-cell receptor (receptors, antigen, T-cell). The CD3 complex includes the gamma, delta, epsilon, zeta, and eta chains (subunits). When antigen binds to the T-cell receptor, the CD3 complex transduces the activating signals to the cytoplasm of the T-cell. The CD3 gamma and delta chains (subunits) are separate from and not related to the gamma/delta chains of the T-cell receptor (receptors, antigen, T-cell, gamma-delta). (12 Dec 1998) |
| receptor-CD3 complex, antigen, T-cell | Molecule composed of the non-covalent association of the T-cell antigen receptor (receptors, antigen, T-cell) with the CD3 complex (antigens, CD3). This association is required for the surface expression and function of both components. The molecule consists of up to seven chains: either the alpha/beta or gamma/delta chains of the T-cell receptor, and four or five chains in the CD3 complex. (12 Dec 1998) |
