Monoclonal antibodies clustered as CD3 recognize the constant structure of the CD3/TcR (T cell receptor) complex.
This complex is present on mature T cells and during thymopoiesis.
CD3/TcR is called the T cell receptor complex.
This complex is composed of different structures, i.e.
TcRa, TcRb, TcRg, TcRd, CD3g, CD3d, CD3e, the x-chain, and the h-chain.
Less than 10% of human peripheral T cells express the g/d TcR complex.
The function of a/b and g/d heterodimers is the recognition of peptide antigen bound to MHC, followed by T cell activation.
Recent data suggest that CD3 chains are able to function autonomously in signal transduction.
T cells play a major role in activation processes of the immune system.
Detection of these cells is important during immune monitoring.
In addition, a large number of leukemias are T cell-related disorders, in which antibodies recognizing CD3/TcR complex are important diagnostic tools.
Differentiation between AML, T-ALL and B-ALL can be made by immunophenotyping with (early) differentiation markers.
Cell surface detection using CD3 antibodies can be applied for detection of mature T-ALL, while immature T-ALL express cytoplasmic (cyCD3) but no surface CD3.
CD3 antibodies are used, in characterization of various subtypes of chronic lymphoid leukemias.
Examples of these chronic T cell leukemias are T-CLL (Sezary Syndrome) and the peripheral T cell lymphoma (ATLL) which co-express CD2, CD3, CD4 and CD5 antigens.
