Protein 𝛼-1 antitrypsin is used to treat a. Cancer b. Rheumatoid arthritis c. Alzheimer’s disease d. Emphysema
Option D. Emphysema is a chronic disorder where the surface area of respiration decreases due to damaged alveolar walls. It is caused by smoking or deficiency of alpha-1-antitrypsin (A1AT). Alpha-1-antitrypsin is a protein that is produced in the liver and prevents the tissues of the body from being damaged during immune responses. The deficiency of A1AT causes damage to the lung tissues. Emphysema is treated by augmentation therapy wherein the amount of A1AT is increased in the blood to prevent further lung damage.
