Background

CD3 (cluster of differentiation marker 3) is a multi-subunit transmembrane protein that is expressed on the surface of T-cells and forms a complex with the T-cell receptor (TCR) (1-3). CD3 consists of four distinct membrane protein isoforms: CD3-delta (delta), CD3-epsilon (epsilon), CD3-gamma, and CD3-zeta (1-3). The CD3 subunits organize into a complex containing three sets of dimers: CD3-epsilondelta, CD3-epsilongamma, CD3-zetazeta. The CD3 complex binds to the TCR heterodimer (alphabeta or gammadelta) to form the transmembrane TCR-CD3 complex (2-3). Structurally, the CD3 protein chains have an extracellular region, a transmembrane domain, and a cytoplasmic trail region (2-3). The CD3-epsilondelta and CD3-epsilongamma heterodimers also contain an extracellular immunoglobulin (Ig)-like domain, classifying them as part of the immunoglobulin superfamily (2-3). The cytoplasmic tail of each CD3 chain also contains one (delta, epsilon, gamma) or three (zeta) immunoreceptor tyrosine-based activation motifs (ITAMs), for a total of 10 ITAMs in the whole CD3 complex (2-3). Following, TCR binding to peptide major histocompatibility complex (p-MHC), the CD3 ITAMs are phosphorylated by the Src kinase Lck and are important for recruiting ZAP70 and initiating TCR signaling cascade activation (2). While similar in structure, the CD3 chains vary in length and molecular weight (4). The CD3-delta is 171 amino acids (aa) in length with a theoretical molecular weight of 18.9 kDa (4, 5). The CD3-epsilon is 204 aa long and has a theoretical molecular weight of 23 kDa (4, 5). CD3-gamma is 182 aa long with a theoretical molecular weight of 20.4 kDa (4, 5). Finally, CD3-zeta is 164 aa in length with a theoretical molecular weight of 18.6 kDa (4, 5).

CD3 proteins are expressed on the surface of thymocytes during thymocyte development, proliferation, and maturation to T-cells (4, 6, 7). During T-cell development CD4-CD8- double negative (DN) cells differentiate to CD4+CD8+ double positive (DP) cells before progressing to single positive (SP) CD4+ helper T-cells or CD8+ cytotoxic T-cells (4, 6, 7). As CD3 plays an important role in thymocyte development, it is understandable that CD3 defects and mutations in CD3 protein chains cause severe combined immunodeficiencies (SCIDs) (8). Additionally, a subset of CD3+ T-cells that co-express CD20 are described in a variety of diseases including rheumatoid arthritis, multiple sclerosis, CD20+ T-cell leukemia/lymphoma, and HIV (9). Clinical trials and animal models have shown that anti-CD3 monoclonal antibodies are a promising treatment modality for inflammatory disorders and autoimmune diseases, such as type I diabetes (10).
