Abstract

In this project we propose an evaluation of coagulation and homocysteine in the kinetics and extension of the histopathological lesions of arteriosclerosis, using murine models deficient of apoE, of LDL or of FVIII or FIX receptors of coagulation. Hyperhomocysteinemia will be induced by specific diet. We will evaluate the effectiveness of gene therapy in the induction of angiogenesis in model with peripheral arterial ischemia in mice, derived from the local expression of the gene of the VEGF and the Ang1, through the use or viral and non viral vectors, in vivo. Another objective is to evaluate the effect of anticoagulant therapy in the formation of new vessels induced by gene therapy. To identify new risk factors in DVT we will analyze the genic expression of inflammatory mediators in the mononuclear cells of patients with DVT through the technique of cDNA-microarray. We will also evaluate the role of the platelets in the physiopathology and evolution of DVT by the detection of platelet microparticles in patients with DVT (acute and chronic phase) and in asymptomatic carriers of thrombophilia.
