  1. 1. Experimental studies of N-methyl-D-aspartate receptor NR3 subunits

    Författare :Anna Öhman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis focuses on the NR3A and NR3B subunits of the excitatory glutamate receptor N-methyl-D-aspartate (NMDA). Functional NMDA receptors are believed to be tetrameric complexes with combinations of NR1 and NR2 subunits, and possible addition of NR3 subunits. LÄS MER

  2. 2. The N-methyl-D-aspartate receptor subunit NR3A : cloning, expression and interacting proteins

    Författare :Maria Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis focuses on the subunit NR3A, which together with subunits NR1, NR2A-NR2D and NR3B builds the excitatory glutamate receptor N-methyl-D-aspartate (NMDA). The receptor is most likely a tetramer, containing at least one NR1, probably two NR2 and sometimes one NR3 subunit. LÄS MER

  3. 3. Apoptosis And Excitotoxicity In The Death of Cultured And Grafted Dopaminergic Neurones

    Författare :Gabriele Schierle; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ac-YVAD-cmk; MK-801; flunarizine; N-methyl-D-aspartate; voltage-dependent calcium channels; Bcl-2; caspase; excitotoxicity; apoptosis; tyrosine hydroxylase; dopamine; Parkinson s disease; intracerebral transplantation; Poly ADP-ribose polymerase; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Over the past two decades, grafting of embryonic nigral tissue has developed into a feasible therapeutic strategy for Parkinson's disease (PD). It has become apparent that the degree of restoration of dopaminergic neurotransmission by the transplanted cells is highly correlated to the symptomatic relief. LÄS MER

  4. 4. CNS Targets for GH and IGF-1 : Emphasis on Their Regulation in Relation to Cognitive Processes

    Författare :Madeleine Le Grevès; Fred Nyberg; Anders Hallberg; Sigbritt Werner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; Central nervous system; Growth hormone; Insulin-like growth factor-1; Receptor mRNA regulation; N-methyl-D-aspartate receptor mRNA; Morris water maze; Farmaceutisk farmakologi; Pharmaceutical pharmacology; Farmaceutisk farmakologi;

    Sammanfattning : The interest for the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis and its role in the central nervous system (CNS) has grown during the past decade. GH has been associated with psychological functions as sleep, mood, general well-being and learning and memory. LÄS MER

  5. 5. Synthesis and structure activity relationships of competitive NMDA antagonists with analgesic activity

    Författare :Britt-Marie Swahn; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Sammanfattning : The compounds cis-3-(1-oxo-2-phosphonoethyl)-2-piperidinecarboxylic acid 1 and cis-3-(1-hydroxy-2-phosphonoethyl)-2-piperidinecarboxylic acid 2 were synthesized and found to be potent N-methyl-D-aspartate (NMDA) antagonists. NMR analysis showed that 1 prefers a 2eq,3ax chair conformation probably due to a conformer-stabilizing internal hydrogen bond. LÄS MER
