Background
CD20 is a specific signature molecule on the surface of B lymphocytes and is expressed on more than 95% of normal or malignant B lymphocytes. There is no expression of CD20 antigen in hematopoietic stem cells, progenitor cells, and other normal tissues. It consists of 297 amino acids with a molecular weight of 33 kD. CD20 has no internalization or cell surface shedding after binding with anti-CD20 mAb, which is an ideal antigen in the treatdment of B lymphocyte-related diseases. Anti-CD20 mAb can kill most of the lymphoma cells expressing CD20 molecules and normal B cells. Innate normal B cells are not affected by anti-CD20 mAb and can reconstruct B cell population. Therefore, anti-CD20 monoclonal antibodies are increasingly used in the treatment of B cell-related diseases.
