Background: CD20

CD20 is a non-glycosylated phosphoprotein that is expressed on the surface of normal and malignant B cells and functions in mediating calcium transport and B cell differentiation (1,2). CD20 is encoded by the membrane-spanning 4-domain family A member 1 (MS4A1) gene and, in humans, is located on chromosome 11q12 (1). The CD20 protein is 297 amino acids (aa) in length with a theoretical molecular weight (MW) of 33 kDa (1,2). Structurally, the CD20 protein has four membrane-spanning domains, two extracellular loop domains, and intracellular N- and C-terminal domains (1,2). CD20 is expressed at specific stages of B cell maturation including pre-B cells, mature naive and activated B cells, and memory B cells, but is absent from plasmablasts and plasma cells (1,3,4). Expression of CD20 is often increased on malignant B cells associated with various B cell disorders such as chronic lymphocytic leukemia (CLL), multiple sclerosis (MS), and rheumatoid arthritis (2-4). Anti-CD20 monoclonal antibody (mAb)-based therapies have become an appealing target for treating these immune-related disorders and cancers (1-5). Rituximab, a chimeric mAb, was the first FDA approved CD20 monoclonal antibody for the treatment of non-Hodgkin's lymphoma that is now commonly used to treat MS (2,3). Since its initial approval in 1997, several other chimeric and humanized anti-CD20 mAbs have been developed including Ofatumumab, Ublituximab, and Obinutuzumab (1-5). B cell depletion via CD20 mAbs can occur under different mechanisms such as antibody-dependent cellular cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), complement-dependent cytotoxicity (CDC), and direct induction of apoptosis (1-4). Many ongoing studies are focused on combination therapies with CD20 mAbs as an addition to chemotherapy, B cell receptor (BCR) signaling inhibitors, or BH3 mimetics (1,2,4). Additionally, the effects of bispecific antibodies and CD20 chimeric antigen receptor (CAR) T cell therapies are under investigation for the treatment of B cell malignancies (4,5).
