  1. 1. Ethanol-induced modulation of dopamine transmission and synaptic activity in striatal subregions - focus on inhibitory receptors

    Author : Rhona B. C. Clarke; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; ethanol; acetaldehyde; striatum; glycine receptor; GABA A receptor;

    Abstract : Background: Alcoholism is a chronic brain disease, affecting neurocircuitries involved in reward and learning. The rewarding effects of alcohol (ethanol) are believed to result from increased dopamine levels in the nucleus accumbens (nAc) via the mesolimbic system. READ MORE

  2. 2. GABA signaling regulation by GLP-1 receptor agonists and GABA-A receptors modulator

    Author : Omar M. Babateen; Bryndis Birnir; Lena Eliasson; Uppsala universitet; []
    Keywords : Neuroscience; Neurovetenskap;

    Abstract : GABA (γ-aminobutyric acid) is the main neuroinhibitory transmitter in mammalian brains.  It binds to GABA-A and GABA-B receptors. The GABA-A receptors are ligand-gated chloride channels. A variety of GABA-A receptor agonists and antagonists have been developed to study the GABA-mediated inhibition and to explore new medications. READ MORE

  3. 3. GABA-steroid effects in healthy subjects and women with polycystic ovary syndrome

    Author : Helena Hedström; Torbjörn Bäckström; Marie Bixo; Ian Milsom; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allopregnanolone; isoallopregnanolone; gonadotropins; GABA-A receptor; women; polycystic ovary syndrome; saccade; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Background: The progesterone metabolite allopregnanolone is involved in several clinical conditions in women, e.g. premenstrual dysphoric disorder. It is a very potent GABA-steroid with GABA-A receptor effects similar to other GABA-agonists, e. READ MORE

  4. 4. Tolerance and antagonism to allopregnanolone effects in the rat CNS

    Author : Sahruh Turkmen; Inga-Maj Johansson; Agneta Nordberg; Umeå universitet; []

    Abstract : Many studies have suggested a relationship between sex steroids and negative mental and mood changes in women. Allopregnanolone, a potent endogenous ligand of the GABA-A receptor and a metabolite of progesterone, is one of the most accused neuroactive steroids. READ MORE

  5. 5. Glutamate and GABA signalling components in the human brain and in immune cells

    Author : Amol K. Bhandage; Bryndis Birnir; Gerard P. Ahern; Uppsala universitet; []

    Abstract : Glutamate and γ-aminobutyric acid (GABA) are the principal excitatory and inhibitory neurotransmitters in the central nervous system (CNS). They both can activate their ionotropic and metabotropic receptors. READ MORE
