  4. 2. Regulation of insulin producing cells, stress responses and metabolism in Drosophila

    Author : Neval Kapan; Dick R. Nässel; Alberto Ferrus; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insulin signaling; Drosophila melanogaster; peptide hormones; neuropeptides; GABA; funktionell zoomorfologi; Functional Zoomorphology;

    Abstract : In Drosophila, neuropeptides have regulatory roles in development, growth, metabolism and reproduction. This study focused on GABA and the neuropeptides Drosophila tachykinin (DTK), short neuropeptide F (sNPF), adipokinetic hormone (AKH), corazonin (CRZ) and Drosophila insulin-like peptides (DILPs) as possible regulators of metabolic stress responses and homeostasis.

  5. 3. Morphological and functional effects of insulin signaling and the bHLH transcription factor Dimmed on different neuron types in Drosophila

    Author : Yiting Liu; Dick R. Nässel; Irene Miguel-Aliaga; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; insulin signaling; Dimm; neuropeptide; insulin receptor; insulin-like peptide; drosophila; funktionell zoomorfologi; Functional Zoomorphology;

    Abstract : In Drosophila, the insulin signaling pathway is at the interface between dietary conditions and control of growth and development, reproduction, stress responses and life span. Eight insulin like peptides (Dilp1-8), an insulin tyrosine kinase receptor (dInR) and its downstream components, as well as a relaxin-like receptor type (Lgr3) form the core of this signaling.

  6. 4. Neuropeptides and GABA in control of insulin producing cells in Drosophila

    Author : Jeannette Söderberg; Åsa Winther; Dick R. Nässel; Susan Broughton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila; insulin signaling; metabolism; feeding; DTK; DSK; GABA; stress resistance; funktionell zoomorfologi; Functional Zoomorphology;

    Abstract : Insulin plays an important role in metabolic regulation as well as in growth, fecundity and stress resistance. In order to understand more about the regulation of insulin-like peptide (DILP) production and release we investigate the impact of neuropeptide (DTK) signaling and classical neurotransmitter (GABA) signaling onto the insulin producing cells of the Drosophila brain.

  7. 5. Multiple neurotransmitter inputs modulate circadian clock neurons in Drosophila

    Author : Yasutaka Hamasaka; Dick Nässel; François Rouyer; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; circadian; Drosophila; neurotransmitter; G-protein coupled receptor; Neurobiology; Neurobiologi;

    Abstract : Most animals have endogenous circadian clocks, which drive daily rhythms in behavior and physiology to adapt to daily cycles of the environment. Several sets of neurons have been identified as circadian pacemakers (clocks) in the brain of Drosophila melanogaster, but the neuronal circuits and neurotransmitters signalling circadian information are poorly known.
