Abstract:
Phagosome maturation is a dynamic process involving the engulfment and degradation of pathogens by phagocytic cells. However, several pathogens have employed mechanisms that facilitate their survival and escape from the phagosome. The fungal pathogen, Candida albicans, is capable of switching from yeast to hyphal form to facilitate its pathogenicity and escape from the phagosome. Rab GTPases are key regulators in phagosome maturation by mediating interactions with the endocytic pathway and leading to biogenesis of the phagolysosome.

Dendritic cells (DCs) are specialized members of the innate immune system that are responsible for the initiation of primary adaptive immune responses whose purpose is to resolve infection and inflammation. During most viral infections, mature dendritic cells present critical viral antigens to naïve T-cells within secondary lymphoid organs, resulting in the generation of an antigen-specific adaptive immune response and clearance of the virus. During infection with HIV-1 however, the virus is not cleared and a chronic systemic infection develops characterized by immune dysfunction, CD4+ T-cell

GPR17, a uracil nucleotide cysteinyl leukotriene receptor, belongs to the GPCR (G protein coupled receptor) family.

Interestingly, our laboratory found GPR17 in thrombocytes. However, we do not know whether it has any function in thrombocyte aggregation or the nature of the ligand. In this paper, we studied the role of GPR17 in hemostasis, which is a fundamental defense mechanism in the event of injury. Using zebrafish as a mode

Oocytes of most species assemble and maintain a functional bipolar spindle in the absence of centrosomes. Strikingly, after bipolar spindle formation, oocytes arrest in metaphase for several hours before fertilisation. How the dynamic spindle maintains its bipolarity during this long arrest is poorly understood. I hypothesise that the bipolar spindle is stably maintained by changes in the distribution of microtubule-associated proteins (MAPs) on the spindle during the long oocyte arrest.

Abstract:
Like most other vertebrate oocytes, oocytes from Xenopus laevis are physiologically arrested at the first meiotic prophase. Re-initiation of meiosis, or oocyte maturation, is triggered by progesterone. Progesterone-induced oocyte maturation is thought to involve inhibition of cAMP-dependent protein kinase (protein kinase A or PKA). However, changes in PKA activity in live oocytes have never been demonstrated. I have developed a novel approach to monitor endogenous PKA activity in live oocytes, by expressing a PKA-specific substrate in oocytes followed by monitoring its PKA phosphorylation sta

Abstract:
Nitrogen is one of the most abundant elements on Earth and mostly found in the atmosphere as the inert gas N2. Therefore the nitrogen cycle is important for maintaining the bioavailabilty of nitrogen for organisms. Denitrification is a process that closes the nitrogen cycle by subsequent conversion of nitrate to dinitrogen with reduction of nitrate to nitrite being the very first necessary step. The bacterial periplasmic nitrate reductase NapA is one of those nitrate reducing enzymes and contains a molybdenum cofactor and a [4Fe-4S] cluster as cofactors. As a periplasmic terminal reductase Nap

Abstract:
Aspects of tissue protein metabolism were studied in different groups of Atlantic salmon (Salmo salar). Firstly, 2 groups of sea water salmon were fasted for 3 and 5 days, prior to the measurement of tissue fractional rates of protein synthesis (ks, %day), using the method of 3H-phenylalanine flooding. The sensitivity of liver and gill to a short-term fast was indicated by their reduced rates of ks, while in other tissues such as ventricle, stomach and red muscle protein synthesis was unaffected. Both liver and gill are tissues which show the greatest capacities to synthesise protein, expresse

Abstract:
Xenopus laevis oocytes are physiologically arrested at the first meiotic prophase. Progesterone reinitiates meiosis (maturation) through inhibition of an oocyte adenylyl cyclase (AC) and reduction of intracellular cAMP. However, the mechanism by which progesterone regulates AC activity and cAMP level still remains unclear. In this thesis, I summarize work I conducted that collectively helps elucidate how high levels of cAMP might be achieved in G2 arrested oocytes. In Chapter 2, I describe our finding that inhibiting endogenous G-protein betagamma subunits, through the use of two structurally

Abstract:
Vesicle (exosome) externalization is a mechanism for removal of obsolescent membrane proteins, such as the transferrin receptor (TFR), during reticulocyte maturation. This thesis involves further characterization of the exosomal phenomenon using avian (nucleated) and mammalian erythroid systems. Chicken reticulocytes release exosomes, indicating independence of this process from enucleation. Exosome release during chicken erythroleukemic cell (HD3) differentiation (representing pre-reticulocyte development) demonstrates that this process commences prior to the reticulocyte stage.<br>The heat s

Abstract:
The hemagglutinin glycoprotein (HA) encoded by measles virus (MV) is a type II integral membrane protein that is expressed at the infected cell surface. The maturation of HA was studied in infected Vero cells. HA oligomerized into a disulfide-linked homodimer with a t$ sb{1/2}$ of 30 min. The rate of transport of HA to the medial Golgi complex was also examined using endoglycosidase-H and found to occur with a t$ sb{1/2}$ of 2 hr. Genes encoding two mutant HA proteins shortened at their C-terminal end by either 18 (HA$ Delta$18) or 223 (HA$ Delta$223) amino acids were constructed and studied i

Abstract:
Dendritic cells (DC) sense infection in their microenvironment and undergo a dynamic process of changes in phagocytic capacity, morphology and migratory activity in order to induce optimum T cell immunity. The acquisition of these properties is termed "DC maturation". In this study, key selected aspects of this DC maturation process have been explored. One aspect of DC maturation is the signalling pathways that DC use to respond to micro-environmental signals. DC respond to conserved microbial structures in their micro-environment via pattern recognition receptors including Toll-like receptors

Abstract:
Autophagy is a self-degradative process involved in the turnover of cellular components in response to nutrient starvation or to organelle damage. During this process, portions of cytoplasm are sequestered by double-membrane vesicles, the autophagosomes, and degraded after fusion with lysosomes. Different protein complexes participate to autophagosome formation including various components of the class III phosphatidylinositol-3-OH kinase complex (Ambra1, Beclin 1, Vps34, Vps15, UVRAG) and most of the Atg genes. Here, I show that Ambra1 also plays a role in the regulation of the late steps of
