The induction of E-selectin and ICAM was We have designed polyethylene glycol (PEG-) coated (sterically stabilized) significantly prevented by both high and low doses of PPLEC or indomethacin liposomes to carry high payloads of imaging reagents such as paramagnetic treatment. However, the prevention of VCAM production was only seen in high compounds (e.g. fluorescent dyes) to cells with the goal to improve non-invasive PPLEC not only possess anti-inflammatory effect (previous study) but also molecular imaging modalities by specific targeting. To target atherosclerotic prevents pro-inflammatory cytokines-induced adhesion molecule production in plaques we have covalently coupled selected biomarkers to the distal ends endothelia. These data indicate that PPLEC can be a potential material to of the PEG-chains, which are located at the surface of the liposomes. These develop in preventing chronic inflammatory-related diseases.
