Neopterin
Neopterin is a molecule produced by immune cells, particularly macrophages, in response to stimulation by interferon-gamma. It is considered a marker of immune system activation and inflammation. Elevated levels of neopterin in urine or blood can indicate increased immune activity, often seen in infections, autoimmune disorders, or chronic inflammatory conditions. Because it reflects cellular immune response, neopterin is sometimes used to monitor disease progression or immune system status.
Description
What is neopterin?
Neopterin is a compound released by immune cells when the immune system is activated, serving as a marker of inflammation and immune response.
What does a high level of neopterin indicate?
Elevated neopterin levels can suggest increased immune activity, which may occur during infections, autoimmune diseases, or chronic inflammation.
Can neopterin levels be used to diagnose specific diseases?
Not directly. While high neopterin suggests immune activation, it is a non-specific marker and must be interpreted in context with other clinical findings.
