  2. 1. Morphologican and functional studies on the Drosophila neuromuscular system during postembryonic stages

    Author : Ana Beramendi; Rafael Cantera; Prof. Carlos Dotti; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; neuromuscular system; Rel-proteins; fly brain; rhythmic morphology; aging; ; Neurobiology; Neurobiologi;

    Abstract : The nervous system of the fruit fly Drosophila melanogaster has emerged as an excellent model for fundamental neuroscience as well as for biomedical research of human neurological diseases. In this thesis, two aspects of the neuromuscular system have been investigated: the role of the IkB-protein Cactus in the larval neuromuscular junction and the morphology of motor terminals throughout adult life.

  4. 2. Chemical signalling in the Drosophila brain : GABA, short neuropeptide F and their receptors

    Author : Lina E. Enell; Dick Nässel; Jonathan Bacon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insect nervous system; Drosophila; GABA; sNPF; GPCR; ion channel receptor; feeding; metabolic stress; olfaction; antennal; lobe; mushroom body; Morphology; Morfologi; funktionell morfologi; Functional Zoomorphology;

    Abstract : Gamma-aminobutyric acid (GABA) and short neuropeptide F (sNPF) are widespread signalling molecules in the brain of insects. In order to understand more about the signalling and to some extent start to unravel the functional roles of these two substances, this study has examined the locations of the transmitters and their receptors in the brain of the fruit fly Drosophila melanogaster using immunocytochemistry in combination with Gal4/UAS technique.

  5. 3. Static and Dynamic Measurements of Neurotransmitters in Drosophila Brain

    Author : Carina Berglund; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Neurotransmitters, the substances neurons use for communication, and their precursors and metabolites are of obvious importance for the wellbeing of the individual and when the neurotransmitter balance is off it can lead to catastrophic suffering as in the addiction to drugs or in neurodegenerative diseases. By understanding how neurons communicate with the environment, treatment may be found to aid in the symptoms of unbalance. READ MORE

  6. 4. Immunological studies in the brain and signaling pathways in experimental African trypanosomiasis

    Author : Ahmed Sharafeldin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Trypanosoma brucei; Cytokines; Chemokines; IFN-gamma; Transcription factors;

    Abstract : African Trypanosomiasis is a disease prevalent among humans and animals in tropical Africa which is caused by the extracellular hemoflagellate Trypanosoma brucei (T. b.). READ MORE

  7. 5. Interrogation of drug effects on the lipid composition of single cells and Drosophila brain using ToF-SIMS imaging

    Author : Thuy Mai Hoang Philipsen; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Keywords: Mass spectrometry imaging; PC12 cell.; ToF-SIMS; zinc deficiency; lipid change; methylphenidate; cocaine; cognition; omega-3 and 6- fatty acids;

    Abstract : Lipids are essential for all living organisms on Earth. The most important function of lipids is that they act as the building blocks of cellular membranes. Lipids consist of polar head groups and non-polar tail groups and assemble into bilayer structures to create cell and organelle membranes. READ MORE
