  2. 1. The γ-aminobutyric acid and proton signaling systems in the zebrafish brain : Characterization and effect of stress

    Author : Arianna Cocco; Svante Winberg; William H. J. Norton; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; g-aminobutyric acid GABA ; GABAA receptors; adult zebrafish; central nervous system; gene expression profiling; extracellular acidification.; Biokemi; Biochemistry;

    Abstract : The central nervous system of vertebrates is continuously processing sensory information relayed from the periphery, integrating it and producing outputs transmitted to efferents. In the brain, neurons employ an array of messenger molecules to filter afferent information and finely regulate synaptic transmission. READ MORE

  4. 2. 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

  5. 3. Effects of neuroactive steroids on the recombinant GABAA receptor in Xenopus oocyte

    Author : Mozibur Rahman; Ming-De Wang; Bjarke Ebert; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; GABA; GABAA receptor; neuroactive steroids; Obstetrics and gynaecology; Obstetrik och gynekologi;

    Abstract : Introduction: Neuroactive steroids represent a class of both synthetic and naturally occurring steroids that have an effect on neural function. In addition to classical genomic mechanism by the hormones progesterone, deoxycorticosterone and testosterone 3α-OH metabolites of these hormones enhance GABAA receptor through rapid non-genomic mechanism.

  6. 4. 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. 5. Pharmacophore Refinement and Lead Optimization - A study of the benzodiazepine site of the GABAA receptors

    Author : Erik Lager; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; Naturvetenskap; Natural science; Quinolone; Flavone; Pharmacophore; GABA; Benzodiazepine;

    Abstract : Structure activity relationship studies of synthetic flavone derivatives have been utilized to refine and evaluate a pharmacophore model of the benzodiazepine binding site of the GABAA receptors, originally developed by Zhang et al. (Drug Des. Discovery 1995, 12, 193-248). READ MORE
