  2. 1. Microglial Glutamate Transporters - Regulation of Expression and Possible Physiological Functions

    Author : Mikael Persson; Göteborgs universitet; []
    Keywords : anaphylatoxin; central nervous system; herpes simplex virus; glutamate transport; glutathione; GLT-1; lipopolysaccharide; microglia; neuroinflammation; oxidative stress; protection; tumour necrosis factor-alpha;

    Abstract : Microglia are considered as the immunocompetent cells of the central nervous system (CNS). Being the first line of defence, they have prominent roles in monitoring the homeostasis and the extracellular milieu and can rapidly and specifically react to any disturbances such as brain trauma, ischemia, neurodegenerative diseases, or infections.

  4. 2. Across Borders : A Histological and Physiological Study of the Subthalamic Nucleus in Reward and Movement

    Author : Nadine Schweizer; Åsa Wallén-Mackenzie; Dai Stephens; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subthalamic nucleus; STN; basal ganglia; locomotion; hyperlocomotion; rearing; ventral tegmental area; VTA; dopamine; glutamate; vesicular glutamate transporter 2; Vglut2; Parkinson s disease; deep brain stimulation; subpopulation; conditional knock-out; optogenetic; co-expression; in situ hybridization; self-administration; reward behavior; mouse genetics;

    Abstract : The basal ganglia are the key circuitry controlling movement and reward behavior. Both locomotion and reward-related behavior are also modified by dopaminergic input from the substantia nigra and the ventral tegmental area (VTA). READ MORE

  5. 3. Glutathione in the brain. Studies on efflux and possible implications in neurotoxicity

    Author : Camilla Wallin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glutathione; excitotoxicity; hypoxia-ischemia; brain; rat; anoxia-aglycemia; g-glutamyl transpeptidase; glutamate; NMDA; oxidative stress; mitochondria; amino acids;

    Abstract : Neuronal cell death in acute insults such as stroke, trauma and epilepsy involves overactivation of glutamate receptors, calcium influx and increased formation of potentially toxic reactive oxygen species. Glutathione is a key component in the antioxidant defense system against reactive oxygen species. READ MORE

  6. 4. Water transport regulation: Biochemical and structural analyses of eukaryotic aquaporins

    Author : Anna Maria Nyblom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray crystallography; regulation; aquaporins; function; structure; membrane proteins;

    Abstract : Water is essential for all living beings. Aquaporins are water channel proteins embedded in the membranes of cells. These macromolecules are found in all kingdoms of life and they control water homeostasis by diverse regulation mechanisms. READ MORE

  7. 5. β-N-methylamino-L-alanine (BMAA)-induced neurotoxicity : Studies in vitro and in vivo

    Author : Lisa Ersson; Malin Andersson; Eva B Brittebo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMAA; neurotoxin; neurodegeneration; cellular transport; metabolic profiling; protein-association; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : β-N-methylamino-L-alanine (BMAA) is a neurotoxic non-proteinogenic amino acid produced naturally by cyanobacteria, diatoms and dinoflagellates and it has been detected in samples from fresh and marine water from all over the world. It can bioaccumulate in fish and shellfish, and has a potential to biomagnify in a terrestrial food chain. READ MORE
