Final answer:
Alpha-1 antitrypsin is an inhibitor of neutrophil elastase and its deficiency can result in emphysema, a lung condition characterized by the destruction of alveoli walls.
Step-by-step explanation:
Normal levels of Alpha-1 antitrypsin (AAT) vary within the bloodstream, but deficiencies can lead to lung conditions such as emphysema. In the context of emphysema, AAT plays a crucial role as it inhibits neutrophil elastase, which can damage the elastin in alveoli walls. Emphysema may result from a genetic deficiency of AAT, allowing neutrophil elastase to destroy alveolar walls, thereby compromising lung function.
Alpha-1 antitrypsin (AAT) refers to a protein that inhibits the enzyme elastase, preventing damage to lung tissue. AAT deficiency can lead to emphysema, a disease characterized by the destruction of lung tissue. The levels of AAT in the body can be measured using nl levels, which represent the normal range of AAT concentration in the blood. Depending on the laboratory and the method used for measurement, the nl range for AAT may vary. It is important to note that nl levels are specific to the laboratory and testing method employed.
