Neopterin (Neo) and 7,8-dihydroneopterin (H(2)Neo) are produced by human monocyte-derived macrophages upon stimulation with IFN-gamma. Increased amounts of Neo and H(2)Neo in human body fluids are found in many disorders, including viral infections and autoimmune diseases. Recent data suggest that

The atherosclerotic plaque is an inflammatory site where macrophage cells are exposed to cytotoxic oxidised low density lipoprotein (oxLDL). Interferon-gamma released from T-cells results in macrophage synthesis of 7,8-dihydroneopterin which has antioxidant and cytoprotective activity. Using the human derived monocyte-like

Monocyte cells are exposed to a range of reactive oxygen species (ROS) when they are recruited to a site of inflammation. In this study, we have examined the damage caused to the monocyte-like cell line U937 by peroxyl radicals and

Measurement of plasma neopterin by HPLC with fluorescence detection is used clinically as a marker of immune cell activation in the management of a number of disease pathologies. HPLC analysis of neopterin requires the acidic removal of plasma proteins but
Inga Herpfer et al.

Low density lipoprotein (LDL) oxidation within the artery wall likely represents a key event in the formation of atherosclerotic lesions. Oxidatively modified LDL particles exert chemotactic properties on macrophages, and the uncontrolled uptake of modified LDL by macrophages leads to
