Neopterin, cellular adhesion molecules and myeolperoxidase in patients with stable and unstable angina pectoris Recent data indicate that the serum level of neopterin, a marker of inflammation and immune modulator secreted by monocytes/macrophages, is elevated in patients with acute coronary syndrome (ACS) and seems to be a prognostic marker for major cardiovascular events. Soluble cellular adhesion molecules (sCAMs) and myeloperoxidase (MPO) levels are also related to ACS. The aim of the present study was to evaluate differences in serum levels of neopterin, sCAMs and MPO between coronary artery disease and metabolic syndrome (CAD-MetS) patients with stable and unstable angina pectoris (SAP, UAP), and to clarify the relationships between neopterin and other biomarkers. The study included 60 patients with CAD-MetS who were classified into two groups, 30 patients with SAP and 30 patients with UAP. Twenty healthy subjects were selected as controls (C). Serum soluble vascular cell adhesion molecule-1 (sVCAM-1), intercellular cell adhesion molecule-1 (sICAM-1), sE-selectin and MPO levels were measured by Luminex xMAP technology, and serum neopterin concentrations were measured by radioimmunoassay. Results: Serum levels of neopterin, MPO, sVCAM-1, sICAM-1, and sE-selectin were significantly higher in patients with UAP in comparison with the group of healthy controls (P < 0.05). Patients with SAP also had higher levels of these biomarkers than those in healthy controls (P < 0.05), except for sE-selectin. The biomarker level did not differ between the two patient groups, except for MPO, which was significantly higher in the USP group (P < 0.05). Neopterin was significantly correlated only with sVCAM-1 (P < 0.05). In conclusion, CAD-Met patients with SAP had more apparent raised levels of serum sICAM-1 and sVCAM-1, simultaneously with higher MPO and neopterin concentrations, in comparison to those in healthy subjects. However, UAP is also associated with more substantial changes in MPO and significantly increased sE-selectin levels. Neopterin concentration was had a close correlation only with sVCAM-1.

Electron Detection

Cells interact with their extracellular environments by means of a variety of cellular adhesion molecules (CAM) and surface ligands. In many instances, CAMs interact in a sequential temporal fashion which suggests that these adhesion molecules may occupy or be polarized to various membrane microdomains on the cell surface. Detection of CAMs can be accomplished by a variety of methods including immunofluorescent microscopy and flow cytometry, and by the use of immunocytochemical markers (i.e. colloidal gold) in electron microscopy. The development of high resolution field emission SEM in the mid 1980's and the Autrata modification of the YAG detector for backscatter electron detection at low voltage has greatly facilitated the recognition of colloidal gold probes for detection of surface CAMs. Low voltage FESEM with Bse imaging provides increased resolution of cell surface topography (~3nm at 3-4 keV) which can be observed in 3-dimensions, and simultaneously permits detection/high spatial resolution of immunogold label by atomic number contrast.
