Bacterial lipopolysaccharides (LPS) induce the activity of guanosine triphosphate (GTP)-cyclohydrolase I (GTP-CHI), the first enzyme in the biosynthesis of tetrahydrobiopterin (H4bip) from GTP in endothelial cells and macrophages. In these and other cells, LPS also acts costimulatory with cytokines,

Synthesis and in vitro evaluation of 2-amino-4-N-piperazinyl-6-(3,4-dimethoxyphenyl)-pteridines as dual immunosuppressive and anti-inflammatory agents.

To get a measure of the extent of induction of nitric oxide synthase in infection with human immunodeficiency virus type-1 (HIV-1) in vivo, we estimated serum nitrite plus nitrate concentrations in 110 HIV-1 infected individuals compared to 76 blood donors. To monitor cytokine action and to measure

The neopterin derivatives, neopterin and 7,8-dihydroneopterin, modulate the cellular oxidant-antioxidant balance as well as the expression of the inducible nitric oxide synthase (iNOS) gene. Since apoptosis can be induced by reactive oxygen intermediates and nitric oxide (NO) we investigated whether
