With reference to monoclonal antibodies, often mentioned in news, consider the following statements: I. They are man-made proteins. II. They stimulate immunological function due to their ability to bind to specific antigens. III. They are used in treating viral infections like that of Nipah virus. Which of the statements given above are correct?
- A.I and II only
- B.II and III only
- C.I and III only
- D.I, II and III
▶ Answer & Explanation
Correct answer: D. I, II and III
Monoclonal antibodies are produced in laboratories by cloning a single type of immune cell, ensuring they are identical and man-made. Their therapeutic efficacy stems from their high specificity in binding to target antigens, whether on pathogens or cancer cells, thereby triggering immune responses or blocking pathogen activity. While primarily used for conditions like cancer and autoimmune diseases, they are increasingly being explored and utilized for treating viral infections, including those caused by emerging viruses.
