Abstract:

Apolipoprotein E (apoE) plays a pivotal role against atherosclerosis. This role is exerted only by apoE delivered at the lesion level. The main aim of this project is to obtain apolipoprotein-fullerene based nano-systems (AFN) targeted toward the atherosclerotic plaque through transferrin receptor. The transferrin or anti-transferrin receptor monoclonal antibody included in AFN will facilitate their transcytosis through the endothelial layer and will enhance their binding on the macrophage-foam cells. We plan to achieve the following objectives: (1) Setting up a series of AFNs using recombinant apoE3 or apoE3-HRP chimera alone or together with transferrin or with anti-transferrin receptor monoclonal antibodies; (2) Biochemical characterization of the obtained AFNs by size, apolipoprotein/Tf or TfRMoAb ratio, lipid binding capacity; (3). Functional characterization: (i) In vitro tests of the capacity of AFNs to cross the endothelial layer, to bind on macrophage surface and to participate in the cholesterol efflux from the macrophage-foam cells; (ii) In vivo AFNs ability to reduce the atherosclerotic plaques in animal models. Targeting apoE at the plaque using novel biotechnologies will provide an efficient cholesterol efflux from the lipid loaded cells, having significant anti-atherosclerotic benefits. This strategy may open new horizons for developing “synthetic lipoproteins” based on recombinant proteins attached to spherical nanoparticles for diverse therapeutic purposes.

Abstract:

Cardiovascular disease causes more that 55% of all deaths in Europe, hyperlipidaemia being a major contributor. The apolipoproteins have an important role in lipid metabolism. The goal of this proposal is to determine the fine tuning of the apolipoprotein (E, AI and CII) gene regulation by the estrogen/thyroid hormones, in order to reduce the atherosclerotic process. To this, the main objectives are: 1.To identify the molecular mechanisms involved in apolipoprotein gene regulation by estrogen / thyroid hormones. For this we plan to i) localization of the regulatory elements responsible for apolipoprotein gene modulation by estrogen/thyroid hormones, ii) test the interaction of ERs/TRs with other factors and assess their role in apolipoprotein gene regulation, iii) assess the effects of the endocrine disruptors on apolipoprotein expression by estrogen / thyroid hormones; 2. To determine the beneficial effects of combined hormonal treatments in experimental atherosclerosis, by i) assessment of the effects of combined hormonal treatments on lipid plasma levels in normal/atherogenic mice, ii) evaluation of apolipoprotein gene modulation and investigation of atherosclerotic plaques development in mice receiving combined hormonal treatments. The result will elucidate the gene regulatory mechanisms of anti-atherosclerotic apolipoproteins by estrogen/thyroid hormones, and will reveal the link between hormonal imbalance and dyslipidaemia, with clinical applications.

Abstract:

Apolipoprotein E (apoE) is an athero-protective molecule, playing a pivotal role in lipid metabolism. The goal of the project is to induce an increased apoE expression in monocytes and endothelial cells (EC) in order to prevent or regress the atherosclerotic process. We have 3 objectives: 1. To identify the transcriptional mechanisms leading to activation of apoE expression. We will (1a) investigate transcriptional regulation of apoE gene in monocyte and macrophages. (1b) induce upregulation of apoE gene in endothelial cell. 2. To target apoE expressing monocytes at the atherosclerotic plaques. We plan to (2a)induce ex vivo apoE expression in monocytes; (2b)test the minimal monocyte activation that allows the most efficient infiltration in atheroma; (2c)transplant apoE expressing monocytes in apoE null mice and follow plaque regression. 3. To generate a tissue specific transgenic mouse model that expresses apoE specifically in the endothelium and to asses its sensitivity to atherosclerosis. We will (3a)obtain transgenic mice with inducible endothelial-specific expression of apoE3; (3b)assess the association between EC-secreted apoE and different lipoproteins; (3c)determine the ability of EC-secreted apoE to reach the subendothelial space; (3d)evaluate the regression of the atherosclerotic plaques in mice expressing apoE3 in EC. The project will lead to novel apoE based anti-atherosclerotic treatments and will open new horizons for developing cell-specific base therapies.

Abstract:

The project aims to study, to develop and to preliminary test biomimetic structural and functional entities, able to act as gene transfection vehicles of non-viral type, and having a DNA packaging capacity of about 2  5 kilobases. The main features of these entities are: (i) the general structure of a polyplex, (ii) the functionality of a cargo-complex that chemomimic the histones, morphomimic the nucleosome and biomimic a virus like gene vector, (iii) the ability to include or to reversibly bind and transport (bio)chemical species necessary to assist the DNA vehiculation and trafficking, (iv) are based on fullerene-rich polymers and / or dendrimers, (v) the capacity to associate to artificial extracellular matrices, in order to generate gene delivery systems with transfection ability, for ex vivo applications. The developed entities will represent effective tools in genetic and tissue engineering, useful in health restoration, life quality enhancement, and to cure tissue and human organism deficiencies. The envisioned engineering strategy to build biomimetic entities may sustain a spin-off type transfer of knowledge towards hi-tech application areas, with a clear echo in clinics and, finally, in human health. The project involves seven complementary teams hosted by four research and academic institutions. In equilibrated ratios, senior, young and junior researchers will collaborate inside the project frame.
