The role of neopterin in cross-talk between tumor and tumor microenvironment in hepatocellular carcinoma

Pteridines
Neopterin is a marker of activated immune response, but its role in hepatocarcinogenesis is unknown. The present study aims to evaluate the effects of neopterin on prooncogenic/proinflammatory, apoptotic pathways, and other molecular mechanisms in HCC ...

Simultaneous analysis of neopterin, kynurenine and tryptophan by amine-HPLC shows minor oxidative stress from short-term exhaustion exercise

Pteridines, 2019
Introduction: Neopterin, kynurenine and tryptophan can be used to measure activation of monocytes and macrophages during immunological events such as exercise inducing inflammation.

Macrophage Activation Marker Neopterin: A Candidate Biomarker for Treatment Response and Relapse in Visceral Leishmaniasis

Frontiers in Cellular and Infection Microbiology, 2018
The Leishmania parasite resides and replicates within host macrophages during visceral leishmaniasis (VL). This study aimed to evaluate neopterin, a marker of macrophage activation, as possible pharmacodynamic biomarker to monitor VL treatment response ...

Neopterin to Monitor Clinical Pathologies Involving Interferon-γ Production

Pteridines, 2004
Upon stimulation with the cytokine interferon-γ human monocytes/macrophages produce neopterin. Accordingly, measurement of neopterin concentrations in body fluids like blood, urine or cerebrospinal fluid provides information about activation of immune ...

The effect of periodontal therapy on neopterin and vascular cell adhesion molecule-1 levels in chronic periodontitis patients with and without acute myocardial infarction: a case-control study

Journal of Applied Oral Science, 2018
The presence of neopterin in gingival crevicular fluid (GCF) is a marker for local and acute immune activation, and the presence of vascular cell adhesion molecule (VCAM-1) in GCF is accepted as a marker for chronic vascular inflammation. Objectives This

Serum neopterin is elevated in patients infected with Shigella

Gut Pathogens, 2010
Background Neopterin is produced by human macrophages/monocytes when stimulated with interferon-gamma. Production of neopterin is found in serum, cerebrospinal fluid (CSF) and urine of patients with infections by viruses, intracellular bacteria and ...

Neopterin in Bone Banking

Pteridines, 1998
Summary Not only in blood transfusion, but also in transplantation of allogenous bone, infection of patients with bacteria and especially with virus is possible. Neopterin as an unspecific marker of an activated cellmediated immune response is elevated in fresh viral infection even before antibodies are detectable. Additional determination of neopterin
