1. 1. Neuropeptides and GABA in control of insulin producing cells in Drosophila

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

   Sammanfattning : 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.

3. 2. Distribution and modulatory roles of neuropeptides and neurotransmitters in the Drosophila brain

   Författare :Lily Kahsai Tesfai; Åsa M. E. Winther; Ronald Strauss; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; central complex; locomotor behavior; co-transmitter; metabotropic receptor; metabolic stress; Neurobiology; Neurobiologi; zoologi; Zoology;

   Sammanfattning : The central complex is a prominent neuropil found in the middle of the insect brain. It is considered as a higher center for motor control and information processing. LÄS MER

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

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

   Sammanfattning : 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. 4. Distribution and actions of insect tachykinin-related peptides

   Författare :Åsa Winther; Peter D. Evans; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Insects; Insekter;

   Sammanfattning : Tachykinin-related peptides (TRPs) have been identified in a number of invertebrates belonging to the mollusca, euchiurdea, crustacea and insecta. The TRPs are named after their sequence similarities and possible common evolutionary relationship to the vertebrate tachykinins. LÄS MER

7. 5. Tachykinin-related peptide signaling and its role in metabolic stress in Drosophila

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

   Sammanfattning : 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. LÄS MER
