Background: CD3
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).
