Thesis, université Paris-Saclay, 2021. http://www.theses.fr/2021UPASL022.
Texte intégralThe aggregation of alpha-synuclein and the spread of aggregates from neuron to neuron have been consistently shown to be at the heart of the pathophysiological process of devasting neurodegenerative diseases like Parkinson's disease, dementia with Lewy bodies or multiple system atrophy. While fibrillar alpha-synuclein rich deposits are a common hallmark of synucleinopathies, distinct pathological phenotypes are observed. We hypothesize that different "strains" of fibrillar alpha-synuclein with different affinity/tropism, internalization and seeding properties, may account for the patho-physiological and clinical heterogeneity in Parkinson's disease and other synucleinopathies. We aim to determine a way to interfere with the binding to neurons of distinct alpha-synuclein assemblies and their prion-like propagation. To this end, we mapped the surface of three distinct alpha-synuclein strains. First, we implemented limited proteolysis and hydrogene-deuterium approaches combined to mass spectrometry in order to map, in vitro, the solvent exposed-surfaces of fibrillar alpha-synuclein assemblies generated in vitro. Second, we studied the processing of different alpha-synuclein strains using primary cultures of neurons and astrocytes in order to analyze the strain degradation characteristics in cellulo, related to the surface specificities determined in vitro. Mapping the surfaces of those assemblies and identification of exposed and protected strain-specific sequences open the way, in the long term, for developing highly specific binders that might either detect specific alpha-synuclein strains or inhibit cell-to-cell propagation disease progression

Resumo: O presente projeto visou estabelecer condições ideais de obtenção de um produto que poderá ser disponibolizado para comercialização no Brasil tendo como foco a encapsulação para aplicação na área alimentícia. Tocoferóis são antioxidantes naturais que podem ser utilizados para enriquecimento de alimentos. Contudo há a necessidade de proteção desse agente ativo por métodos especiais como a microencapsulação. No presente estudo foram desenvolvidos sistemas compostos por micropartículas obtidas por ¿spray chilling" utilizando lipídios interesterificados sem isômeros trans com óleo de soja totalmente hidrogenado na relação de 70:30% m/m respectivamente, com ponto de fusão na faixa de 40-65 °C para formação das matrizes. Alfa-tocoferol foi utilizado como principio ativo a ser encapsulado. Para a obtenção das micropartículas matrizes lipídicas foram fundidas e mantidas em banho à temperatura de 65 °C . O a-tocoferol foi adicionado nas misturas lipídicas que em seguida foram homogeinizados em ultraturrax. As soluções foram pulverizadas em atomizador duplo fluido aquecido também a 65 °C e pressão de ar de 0,25 MPa, com a a tomização efetuada dentro de uma câmara resfriada a 10 °C. Foi realizado um p lanejamento DCCR (Delineamento Central Rotacional) com 2 variáveis independentes: a velocidade de homogeneização (3000 a 11000 rpm) e a concentração de tocoferol (5-25 g/100g). A quantificação do princípio ativo encapsulado foi realizada utilizando técnica isocrática de cromatografia líquida de alta eficiência (CLAE). Os tratamentos foram caracterizados em relação à eficiência de encapsulação, morfologia, tamanho médio, estabilidade e liberação do princípio ativo. Para o estudo da estabilidade os tratamentos foram submetidos à estocagem por 180 dias em três diferentes temperaturas (ambiente 25°C ±5 °C, em estufa 22 °C e freezer a -18°C). Medidas de difração de raios-X (0 , 60, 120, 180 dias) e medidas calorimétricas (tempo zero) foram efetuadas. Foi realizada a incorporação das micropartículas em um produto comercial (Iogurte), que foi avaliado sensorialmente. De forma geral, as partículas lipídicas obtidas neste trabalho apresentaram bons resultados quanto à eficiência de encapsulação e apresentando forma esférica, com paredes contínuas, porém rugosas. Os termogramas, obtidos por calorimetria diferencial de varredura (DSC), em tempo zero, não apresentaram diferenças entre os ensaios. Os difratogramas foram muito semelhantes entre os tratamentos e constatou-se a presença de 3 picos principais que parecem estar associados à forma polimórfica ß. As micropartículas de liberação apresentaram boa capacidade de controle da liberação do composto ativo, mostrando-se potenciais para o uso futuro na indústria de alimentos. Finalmente os resultados da análise sensorial de aceitação não foram estatisticamente significativos para os atributos avaliados
Abstract: This project aimed to establish optimal conditions for obtaining a product that will be commercially available in Brazil, focusing on encapsulation for use in the food industry. Tocopherols are natural antioxidants that can be used for food enrichment.However, there is the need for protection of active agent by special methods, such as microencapsulation. The present study developed systems composed of microparticles obtained by "spray chilling" using an interesterified fat with no trans isomers with fully hydrogenated soybean oil in the ratio of 70:30% w/w respectively, with a melting point in the range of 40-65°C for the formation of matrices to encapsulate a-tocopherol as active principle.To obtain small particles a lipid matrices were melted in a water bath at a temperature of 65°C. The a-tocopherol was added to the lipid mixtures and then homogenized in Ultra Turrax for 5 min.The solutions were sprayed in double-fluid atomizer also heated to 65°C and air pressure of 0.25 MPa, the atomization performed inside a chamber cooled to 10°C. Were conducted a CCR design (Central Compo site Rotational Design) with two independent variables: the speed of homogenization (3000 to 11000 rpm) and the concentration of tocopherol (5-25 g/100 g).The quantification of the active ingredient encapsulated was performed using isocratic HPLC technique. The treatments were characterized with respect to encapsulation efficiency, morphology, average size and stability of the microparticles and release of active ingredient.For the stability study treatments were subjected to storage for 180 days at three different temperatures (ambient 25°C ± 5°C , 22°C in an oven and freezer -18°C).Since x-rays diffraction measurements (0, 60, 120, 180 days) and calorimetric measurements (time zero) were made. Were performed the incorporation of the microparticles in a commercial product (yogurt), which was evaluated using the sensory evaluation.In general, the lipid particles studied in this work showed good results in terms of encapsulation efficiency showing spherical shape, with solid rough walls. The thermograms obtained by DSC at time zero did not differ between trials.The XRD patterns were very similar among treatments and found the presence of three major peaks that are associated with the polymorphic form ß. The microparticles showed good ability to control the release of the active principle, showing potential for future use in the food industry. Finally the results of an smooth sensory acceptance indicated that the tested samples did not differ statistically from the standard sample for evaluated attributes
