Antibody therapy, also known as immunotherapy, is a form of treatment that uses antibodies to specifically target and neutralize harmful substances in the body, such as toxins, viruses, or cancer cells. These antibodies can be produced by the body's immune system, synthesized in a lab, or derived from animals. Antibody therapy has become a promising approach for the treatment of various diseases, including cancer, autoimmune disorders, infectious diseases, and inflammatory conditions. By targeting specific molecules or proteins on the surface of cells, antibodies can directly inhibit their function or stimulate the immune system to attack them. This targeted approach minimizes damage to healthy tissues and reduces side effects compared to traditional treatments like chemotherapy or radiation therapy. Antibody therapy has shown promising results in clinical trials and is being increasingly used in the treatment of a variety of medical conditions.
