Question

With reference to monoclonal antibodies, often mentioned in news, consider the following statements:They are man-made proteins.They stimulate immunological function due to their ability to bind to specific antigens.They are used in treating viral infections like that of Nipah virusWhich of the statements given above is/are correct?

Accepted Answer

Monoclonal antibodies (mAbs) are laboratory- engineered proteins that mimic the immune system's natural ability to fight harmful pathogens. Hence statement I is correct. Produced from a single clone of B-cells, they are designed to bind to specific antigens such as those found on viruses, bacteria, or cancer cells. This targeted action allows them to neutralize threats, mark infected or malignant cells for destruction, or block harmful biological processes. Hence statement II is correct. mAbs are widely used in treating cancers, autoimmune disorders, and viral infections like COVID-19, Ebola, and Nipah. Their precision makes them powerful tools in both therapy and diagnostics. In India, the monoclonal antibody from Australia has been used on some individuals around the world. Its use was found to be safe. Hence statement III is correct.
