What is Monoclonal antibody therapy?

Monoclonal antibody therapy is a form of immunotherapy that uses monoclonal antibodies to bind monospecifically to certain cells or proteins. The objective is that this treatment will stimulate the patient's immune system to attack those cells. Alternatively, in radioimmunotherapy a radioactive dose localizes a target cell line, delivering lethal chemical doses. Antibodies have been used to bind to molecules involved in T-cell regulation to remove inhibitory pathways that block T-cell responses. This is known as immune checkpoint therapy.

It is possible to create a mAb that is specific to almost any extracellular/cell surface target. Research and development is underway to create antibodies for diseases.
