Neopterin is a molecule produced by immune cells, especially macrophages, in response to stimulation by interferon-gamma. It serves as a marker of immune system activation and inflammation. Elevated neopterin levels in urine or blood can indicate increased immune activity, commonly seen in infections, autoimmune diseases, or chronic inflammatory conditions. Since it reflects the cellular immune response, neopterin is sometimes used to track disease progression or the status of the immune system.
Neopterin is a compound released by immune cells when the immune system is activated, serving as a marker of inflammation and immune response.
Elevated neopterin levels may indicate increased immune system activity, which can happen during infections, autoimmune disorders, or chronic inflammation.
No, not directly. Although elevated neopterin indicates immune system activation, it is a non-specific marker and should be evaluated along with other clinical findings.
