Abstract:

La lipase pancréatique apparentée de type 2 du cobaye (GPLRP2) hydrolyse une grande variété de substrats lipidiques. Elle montre cependant une sélectivité selon l’organisation supramoléculaire du substrat et la présence de surfactants comme les sels biliaires (NaTDC). Nous avons utilisé la spectroscopie infrarouge (FTIR) pour étudier les interactions entres les phospholipides (DPPC), les surfactants et la GPLRP2 dans des conditions expérimentales proches de celles du tractus digestif. Pour étudier l’étape d’adsorption indépendamment de l’hydrolyse, un variant inactif de GPLRP2 (S152G) a été pr

Abstract:

Cytochrome P450 (GYP) are a family of membrane-bound enzymes which form a component of the mixed function oxidase (MFO) system and are involved in the metabolism of many endogenous and exogenous compounds and, as such, play key roles in many physiological, pharmacological and toxicological processes. Due to the diversity of their substrates, it is essential to gain an understanding of how their activities can be modulated. The membrane lipid environment of CYP isoforms has proved to be an essential component for their optimal activities and consequently investigations into this aspect of modul

Abstract:

The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place. The study of these processes is often complicated by the need to create in vitro systems that mimic the environment in which these proteins are normally found in vivo. This thesis describes some of the methods available for membrane-protein studies in membrane-mimetic system

Abstract:

Hand hygiene is a major and fundamental topic in patient management to avoid health care-associated infections. According to the WHO alcohol-based hand rubs are the preferred means in clinical antisepsis. However, the frequent use of alcohol-based hand rubs can cause adverse events, which negatively impact user compliance, demonstrating a risk for patients. Adverse events are based on protein denaturation and stratum corneum lipid extraction. The aim of this work was to develop in vivo assays for lipid-processing enzymes in the stratum corneum as biomarkers to be routinely used in the evaluati

Glycosyltransferases from three types of organisms have been investigated; one is responsible for vital lipid synthesis in Arabidopsis thaliana (atDGD2) and adjusts the lipid content in biomembranes if the plant experiences stressful growth conditions.

Abstract:

Glycosaminoglycans (GAGs) are linear polysaccharides whose disaccharide building blocks consist of an amino sugar and either uronic acid or galactose. They are expressed on virtually all mammalian cells, usually covalently attached to proteins, forming proteoglycans. GAGs are highly negatively charged due to an abundance of sulfate and carboxylic acid groups, and are structurally very diverse, with differences arising from chain length, the type of monomeric units, the linkages between each monomeric unit, the position of sulfate groups, and the degree of sulfation. GAGs are known to interact

Abstract:

The sterol biosynthetic pathway is essential for growth of all eukaryotic cells and the main target of antifungal agents. The emergence of resistance to these antifungals in an already ill patient population indicates a need to develop drugs that have a broad spectrum of activity among pathogenic fungi and have minimal patient toxicity. Squalene synthase is the first committed step in the sterol pathway and has been studied intensively for development of antifungal agents. While the overall architecture of this enzyme is identical throughout eukaryotes, it was shown that plant and animal genes

Monotopic proteins represent a specialized group of membrane proteins in that they are engaged in biochemical events taking place at the membrane interface.

Thus, from an evolutionary point of view, anchoring into the membrane interface enables monotopic enzymes to confer sensitivity to a changing environment by regulating their activities in the lipid biosynthetic pathways in order to maintain a cer

Abstract:

Metabolic energy is most efficiently stored as triacylglycerol (TAG). This neutral lipid accumulates mainly within adipose tissues, but it can be stored and used in all types of cells. Within cells it is packed in organelles called lipid droplets (LDs). They consist of a core of neutral lipids like TAG and cholesterol esters, which is surrounded by a phospholipid monolayer that mainly consists of phosphatidylcholine (PC). Attached to or inserted into this monolayer are various proteins, mainly LD specific structural proteins or lipid metabolic enzymes. Though excess uptake of nutrition leads t

Abstract:

This master thesis aimed to create and characterize multilayer coatings upon mesoporous silica particles (MSP). The properties of the coating aimed for, was to have a triggerable controlled release, where a targeted enzyme within the intestine, alpha-amylase, is supposed to degrade the coating. The coating was created from a bilayer consisting of DOTAP and DOPC in a 1:3 molar ratio, which serves as a protective coating. The second layer interacting with the surroundings consisted of a starch component, amylopectin, which is degraded by alpha-amylase. The study of the coating was performed with

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico<br>O pinhÃo-manso (Jatropha curcas L.) Ã uma planta oleaginosa, pertencente Ã famÃlia Euphorbiaceae, cujas sementes sÃo reconhecidas como matÃria-prima com potencial para a produÃÃo de Ãleo. Essa planta tambÃm Ã considerada tolerante a condiÃÃes adversas, tais como dÃficit hÃdrico e deficiÃncia nutricional do solo, o que favorece o seu cultivo em regiÃes Ãridas e semiÃridas. Objetivou-se avaliar os efeitos do estresse salino sobre a germinaÃÃo e a mobilizaÃÃo das reservas de sementes e plÃntulas de pinhÃo-manso, por meio de anÃlises

Abstract:

La tuberculose (TB) reste la maladie infectieuse la plus meurtrière au monde. L’absence de développement de médicaments accompagnée de l'émergence de la résistance aux molécules existantes se traduit principalement par l'échec du traitement et la mort. M. tb infecte l'homme par l'inhalation. Le patient peut rester en bonne santé sans aucun symptôme, on parle alors de tuberculose latente. Dans ce cas, la bactérie résider dans le macrophage. La principale caractéristique de M. tb est de rester cacher à l'intérieur de ces cellules, puis se réactiver lorsque le système immunitaire s’affaibli.Mon t
