Adenosine deaminase

Adenosine deaminase (ADA) is an enzyme that plays a crucial role in the immune system by breaking down a substance called adenosine, which helps regulate immune cell activity. ADA converts adenosine into another compound called inosine, maintaining the balance necessary for healthy immune function. If ADA activity is too low, it can lead to immune deficiencies, making the body more vulnerable to infections. Conversely, high ADA levels are associated with certain diseases like leukemia and tuberculosis. Overall, ADA helps ensure immune cells work properly by controlling levels of molecules that influence immune responses.
