ABSTRACT

Micropartículas (MP) são estruturas liberadas por células ativadas ou apoptóticas. Artérias de coelhos lesadas por cateter balão liberam MP fosfatidilserina positivas, com atividade NADPH oxidase produtora de O2 após adição de NADPH, inibida DPI , SOD e MnTBAP. Induziram apoptose de células musculares lisas vasculares. Western blot não revelou proteínas responsáveis pela atividade redox (NADPH oxidase e PDI). MP plasmáticas de pacientes após implante de stent coronário não mostraram atividade NADPH oxidase, mas significativa atividade diaforase 24h pós implante, inibida 40-50 por cento por DPI, SOD e catalase / Microparticles (MP) are released by cells upon activation and apoptosis. Balloon injured rabbit arteries released phosphatidilserine positive MP, with O2 producing NADPH oxidase activity upon NADPH addition, inhibited by DPI, SOD and MnTBAP. MP induced cultured vascular smooth muscle cells apoptosis. Western blot did not show redox active proteins (NADPH oxidase and PDI). Plasmatic MP from coronary stented patients did not have NADPH oxidase activity, but had significant diaphorase activity, inhibited 40-50 per cent by DPI, SOD and catalase...
