  2. 1. Tachykinin-related peptide signaling and its role in metabolic stress in Drosophila

    Author : Ryan Tyge Birse; Dick Nässel; Micheal Pankrantz; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurobiology; Neurobiologi;

    Abstract : Tachykinins (TKs) constitute a highly conserved family of multifunctional neuropeptides that are known to be involved in a multitude of functions in mammals. Peptides that are presumed ancestrally related to tachykinins, so called Tachykinin-related peptides (TKRP) have been identified in invertebrates. READ MORE

  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. 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.

  7. 5. 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.
