Rituximab: A Brief Overview of its Mechanism
In this section, we will provide a concise summary of the mechanism of action of rituximab. By exploring the underlying principles of how rituximab works, we can gain a better understanding of its effectiveness in treating certain conditions.
Targeting B Cells
Rituximab, a monoclonal antibody, exerts its therapeutic effects by specifically targeting a type of white blood cell called B lymphocytes, also known as B cells. B cells play a crucial role in the immune response, producing antibodies that help the body fight off infections and other harmful agents.
Upon administration, rituximab binds to a protein called CD20, which is predominantly present on the surface of B cells. This binding initiates a series of events that lead to the destruction of these target cells. Rituximab triggers antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC), two processes that result in the elimination of CD20-positive B cells.
Impact on Disease Pathways
By specifically targeting B cells, rituximab interferes with disease pathways that involve these cells. Certain autoimmune disorders, such as rheumatoid arthritis and lupus, are characterized by an overactive immune response and the production of autoantibodies. Rituximab helps to reduce disease activity by depleting the population of B cells responsible for producing these autoreactive antibodies.
Moreover, rituximab has also shown efficacy in the treatment of some B cell malignancies, including non-Hodgkin’s lymphoma and chronic lymphocytic leukemia. By selectively targeting cancerous B cells, rituximab aids in suppressing the growth and progression of these malignancies.
