What is the primary use of monoclonal antibodies in medicine?

Monoclonal antibodies are specifically designed to bind to particular antigens found on the surface of cells or pathogens. This targeted approach allows them to selectively interact with diseases, providing an effective means of treatment for various conditions, especially cancers, autoimmune diseases, and some infectious diseases. By binding to specific targets, these antibodies can help in the recognition and destruction of diseased cells, modify immune responses, or deliver therapeutics directly to affected areas.

The development of monoclonal antibodies is rooted in their ability to provide a precise therapeutic effect while minimizing damage to healthy cells. This contrasts with broader, less targeted therapies that may have a more generalized impact. Therefore, their primary use in the medical field is centered on targeted therapy rather than general enhancement of metabolic processes, direct combat of infections, or pain management.
