Full textThe incorporation and subcellular localization of photosensitizers (pts) are critical determinants of their efficiency in photodynamic therapy. The most important transporters of hydrophobie pts are low-density lipoproteins (LOL). Hypericin (Hyp) is a natural photosensitizing pigment. According to character of Hyp and possibility of its specific targeting into cells through LDL, the study of •. Interaction of Hyp with LDL is important. By means of absorption and fluorescence spectroscopy we showed, that Hyp binds to LOL as monomers up to concentration ratio Hyp/LDL = 30:1. Further increasing ofHyp concentration leads to the formation of Hyp aggregates inside LDL and/or dynamic self-quenching of Hyp. We demonstrated that photoactivated Hyp oxidizes LDL. The maximum of the oxidation of LDL by Hyp is achieved for ratio Hyp/LDL = 30: 1. For higher ratio a decrease in the oxidation of LDL was observed. Further the dependence of the uptake of Hyp by U-87 MG cells on the level of expression of LDL receptors was studied. The results show that the composition of incubation medium influences the concentration of Hyp in cells. The intracellular concentration of Hyp in the presence of LDL is proportional to the Hyp/LDL ratio. A role of LDL receptor pathway for Hyp delivery to cells was confinned by the increase of Hyp uptake in the presence ofLDL for the higher number of LDL receptors. The co-localization experiments showed the lysosomal localization of Hyp with enhanced Hyp concentration for cells with elevated number of LDL receptors when LDL was used as transporters. Our results suggest that LDL and its pathway play an important role in the Hyp delivery and accumulation into the cells

Full textTransmissible spongiform encephalopathies (TSE) are fatal neurodegenerative diseases affecting both humans and animals. They are characterized by the accumulation in central nervous system of a protein called PrPsc. This protein is the isoforme of a physiological protein mainly expressed at the surface of nerve cells and called PrPc. The accumulation and the aggregation of PrPsc come from a shift in tridimensional structure of PrPc. This simple conformational change of PrPc in PrPsc may lead the pathogenesis events encountered during the TSE. Our primary work attempts to inhibit the production of PrPsc using two strategies: first by specifically down regulating the synthesis of PrPc using Silencer RNA technique, secondly by disrupting the cellular localization of the PrPsc production using polyenic antibiotic called filipin. The second part of our work concerns the recruitment of microglial cells during disease. In affected brains, these cells were localized around PrPsc deposits and cerebral lesions. It has been shown that the recruitment of microglial cells precedes neuronal death. Thus understanding the molecular events implied in this recruitment seems essential. In the laboratory, the role of some of neuronal chemokines in this phenomenon has been demonstrated. Neurons incubated with PrPsc liberate chemokines like RANTES provoking the migration of the microglial cells. We have also demonstrated that the repression of the action of RANTES or its receptor CCR5, diminish the migration. Finally, we have determined the intra-neuronal signaling pathway responsible of the chemokines synthesis. Taken together these results represent new original ways for therapy

Full textObesity is a metabolic disorder that is spreading worldwide. Obesity can lead to many diseases such as non-alcoholic fatty liver disease or atherosclerosis. Nutritional approach appears to be an essential strategy for the prevention of metabolic disorders. Indeed, some studies show the correlation between vegetables’ consumption and decrease of cardiovascular diseases.The aim of the study is to evaluate the impact of harvests and storages’ conditions coupled with genetic variability of two vegetables (apples and carrots) on cellular models in which their function is altered during obesity (hepatocytes and adipocytes). Four varieties of apple (Gala, Golden Delicious, Granny Smith and Pink Lady) have been used depending on four different types of storage whereas six varieties of carrots (Karotan, Bolero, Presto, Deep Purple, Kintoki and Blanche des Vosges) have been harvested in four different ways.The strategy of this project is to put some proper protocols for cellular screening in different metabolic processes such as apoptosis, adipocyte differentiation, lipid accumulation, and oxidative stress. Cellulars creening showed variabilities on samples effects depending on storage and harvest conditions, and genetic variabilities. These results allowed us to classify samples according to their most interesting beneficial effects. Then, we chose apple samples with the highest anti-apoptotic effects on endothelial cells in order to investigate their mechanisms of action. The results show that the ability of apple samples to reduce apoptosis is associated with the modulation of oxidative stress

Full textInteraction between T cell and dendritic cell (DC) leads to immune synapse (IS) formation, cytoskeleton remodeling, and reorientation of the T cell microtubule organizing center (MTOC) toward the DC. We have shown that MTOC polarization controls CD154/CD40 signalization necessary to IL-12 production by DC induced by T cells. T cell polarization inhibition also inhibits specifically IFN-gamma secretion without affecting other cytokines. Cdc42 activity or expression reduction which impairs normal immune synapse formation, inhibits specifically IFN-gamma secretion. Cdc42-dependent cytoskeleton remodeling at the IS controls the last step of IFN-gamma production, its secretion. This work underlines the role of T cell polarization in the cross-talk between T cell and dendritic cell and in cytokine secretionby helper T cells
