From what source are most monoclonal antibodies derived?

• A. Plant cells
• B. Mouse or human immune cells
• C. Bacterial cultures
• D. Fungal cells

Answer: (B)

Most monoclonal antibodies are derived from mouse or human immune cells, specifically B cells. This process typically involves the fusion of a specific antibody-producing B cell (usually obtained from an immunized mouse) with a myeloma cell line to create a hybridoma. This hybridoma can then be cultured to produce large quantities of identical monoclonal antibodies that target a specific antigen. The significance of using immune cells is that they are the natural producers of antibodies in the body, allowing for the generation of targeted therapies that can either enhance or inhibit immune responses, depending on the treatment's intended purpose. By leveraging the immune system's ability to recognize pathogens, monoclonal antibodies can be engineered to treat various conditions, including cancers, autoimmune diseases, and infectious diseases. In contrast, other options like plant cells, bacterial cultures, or fungal cells are not used as primary sources for monoclonal antibodies, as they do not naturally produce the same types of specific antibodies that are critical for targeted therapy in humans.
