  2. 6. 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.

  4. 7. Neuron-glial Interaction in the Developing Peripheral Nervous System

    Author : Mikael Corell; Åsa Fex Svenningsen; Klas Kullander; Helgi Schöith; Heape Anthony; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Schwann cell; nonmyelinating Schwann cell; myelinating Schwann cell; development; proliferation; differentiation; myelin; neural stem cell; central nervous system; peripheral nervous system; enteric nervous system; N-cadherin; GABA; GAD; GABA B receptor; baclofen; CGP55485; Neuroscience; Neurovetenskap; Neuroscience; Neurovetenskap;

    Abstract : The nervous system, including the brain, is the most sophisticated organ in the mammalian body. In such a complex network, neuron-glial interaction is essential and controls most developmental processes, such as stem cell fate determination, migration, differentiation, synapse formation, ensheathment and myelination.

  5. 8. GABA and human spermatozoa : characterization and regulation of GABA transport proteins

    Author : Arthur Aanesen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : GABA; spermatozoa; GABA transport; acrosome reaction; sperm motility; progesterone; protein kinase C; GAT-1; GAT-2; GAT-3; BGT-1;

    Abstract : The present project aimed at investigating the interaction between GABA and human spermatozoa under in vitro conditions. Our initial hypothesis was that human spermatozoa had specific binding proteins for GABA and that the binding of GABA to such binding sites could affect sperm function. READ MORE

  6. 9. The optic tectum of the salmon:site of interaction of neurohormonal photoperiodic and neural visual signals. The GABAergic neuronal system and melatonin receptors

    Author : Marie Anzelius; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal anatomy; melatonin receptors; GABA; optic tectum; fish; brain; animal morphology; Djurs anatomi och morfologi;

    Abstract : Melatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. READ MORE

  7. 10. Physiology and Pharmacology of GABAA receptors: The Brakes in the Brain

    Author : Catarina Lindquist; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Fysiologi; Ion channels; GABA; Inhibition;

    Abstract : Inhibitory neurotransmission in the brain is mostly mediated by gamma-aminobutyric acid type A (GABAA) receptors. These receptors are involved in both phasic inhibition (point-to-point inhibition, synaptic transmission) and tonic inhibition (diffuse form of inhibition, brain homeostasis). READ MORE
