  1. 1. Neuropeptides in the human postmortem brain : focus on galanin and its receptors in depression

    Författare :Swapnali Barde; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neuropeptides represent the most diverse family of messenger molecules in the nervous system, which are co-expressed with key neurotransmitters in several brain regions. They modulate synaptic neurotransmission and have, in some cases, also trophic functions. One such neuropeptide, and the focus of the thesis, is ‘galanin’. LÄS MER

  3. 2. Genetic studies of two inherited human phenotypes : Hearing loss and monoamine oxidase activity

    Författare :Jorune Balciuniene; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; linkage analysis; hearing loss; digenic inheritance; allelic association; monoamine oxidase; human genetic diversity; Genetik; Clinical genetics; Klinisk genetik; Medical Genetics; medicinsk genetik;

    Sammanfattning : This thesis focuses on the identification of genetic factors underlying two inherited human phenotypes: hearing loss and monoamine oxidase activity. Non-syndromic hearing loss segregating in a Swedish family was tested for linkage to 13 previously reported candidate loci for hearing disabilities. LÄS MER

  4. 3. G-proteins and adenylyl cyclase in Alzheimer's disease postmortem brain

    Författare :Angela Garcia-Jimnez; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease (AD) is the most common type of dementia in the elderly. The major pathological changes seen in the disease are the formation of neurofibrillary tangles, of which the main component is the hyperphosphorylated form of tau, and the over accumulation of plaques formed by beta-amyloid.

  5. 4. In vivo quantification of extrastriatal dopamine D2 receptors in the human brain

    Författare :Hans Olsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :FLB 457; positron emission tomography; pituitary; receptor density; affinity; benzamide; Scatchard; saturation; receptor occupancy;

    Sammanfattning : The dopamine D2 receptor subtype attracts considerable attention in research on the patophysiology and drug treatment of several neuropsychiatric disorders, such as schizophrenia and Parkinson's disease. The brain imaging technology Positron Emission Tomography (PET) has since long allowed for reliable quantification of the high density of dopamine D2 receptors in large brain structures such as the neostriatum.

  7. 5. In vitro and postmortem studies of the brain opioid system : association to opiate dependence

    Författare :Parisa Zarnegar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Opioid system; brain; gene expression; amygdala; hippocampus; opiate dependence;

    Sammanfattning : Opioids such as heroin are highly addictive illicit drugs. The μ opioid receptor (MOR) plays a central role in mediating the effects of opiates and related opioid. LÄS MER
