CD20 is a protein that is expressed on the surface of B cells but not T cells[1]. It plays an important role in controlling the resting state of these B cells[2] and has been targeted by several monoclonal antibodies to treat various B cell lymphomas, leukemias, and autoimmune diseases[3] [4]. Understanding the biological function of this protein could lead to more effective treatments for these conditions. [5]
