How Does It Work?

Rituxan is an antibody that binds to a specific antigen (known as CD20 antigen) on the surface of B cells.
 B cells are a type of lymphocyte (white blood cell) that plays a role in the immune system and inflammation. By binding to the CD20 antigen, Rituxan signals the body to destroy the B cells (including cancerous B cells, if the medication is being used to treat cancer).
 
Interestingly, Rituxan is made by fusing part of a mouse antibody with part of a human antibody and is grown in the ovary cells of Chinese hamsters.
