Mechanism of Action of Rituximab
Rituximab binds to the CD20 antigen on B-cells, inducing apoptosis and immune-mediated cytotoxicity. This targets cancerous or autoimmune B-cells, helping the immune system eliminate them effectively.
2.1 Targeting CD20 Antigen
Rituximab specifically targets the CD20 antigen, a transmembrane protein expressed on the surface of B-cells. By binding to CD20, rituximab triggers apoptosis and immune-mediated destruction of these cells. This action is critical for treating conditions like non-Hodgkin’s lymphoma and autoimmune diseases, where B-cells play a central role in pathogenesis.
