1. 1. Temporal events in neuronal differentiation and cell death : expression and processing of the Alzheimer's amyloid precursor protein family and a protein at the nuclear pore

   Sammanfattning : The present study had two major objectives: 1) to elucidate the involvement of Alzheimer’s amyloid precursor protein (APP) family in neuronal differentiation, and the effect of the Alzheimer’s disease (AD)-linked mutation APPV642I on signal transduction; 2) to investigate the fate of the nuclear pore complex protein POM121 during apoptosis and to examine the possibility of using green fluorescent protein (GFP)-labelled POM121 as a non-invasive sensor of apoptosis in living (non-fixed) cells.APP is the parent protein of the b-amyloid peptide, which is the major peptide constituent in the “senile plaques” of AD.

3. 2. Characterization of galanin receptors using chimeric peptides and site-directed mutagenesis

   Författare :Ulla Eriksson Sollenberg; Ülo Langel; Anna-Lena Hulting; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; galanin; GPCR; mutagenesis; neuropeptide; Neurochemistry; Neurokemi; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Sammanfattning : Galanin, a 29 (30) amino acid neuropeptide, is found throughout both the central and peripheral nervous systems. It signals via three receptors, GalR1-3, all belonging to the rhodopsin-like G-protein coupled receptors. Galanin and its receptors have been implicated in a vast variety of biological processes.

4. 3. Design and evaluation of drug delivery vehicles

   Författare :Caroline Palm Apergi; Mattias Hällbrink; Gilles Divita; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Sammanfattning : A crucial aspect of drug delivery is efficient transport to the site of action. Thus, there is a need to design and evaluate new delivery vehicles. In this thesis two delivery vehicles, cell-penetrating peptides and bacterial ghosts, were evaluated. LÄS MER

5. 4. Alzheimer Aβ peptides induce dysregulation of C/EBP and NF-кB in glial cells

   Författare :Malin Samuelsson; Kerstin Iverfeldt; Piet Eikelenboom; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; amyloid-β; astrocytes; C EBP; glia; microglia; neuroinflammation; NF-кB; Neurochemistry; Neurokemi; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Sammanfattning : Inflammation is believed to contribute to neurodegeneration in Alzheimer’s disease (AD). AD in turn is believed to be a consequence of accumulated amyloid-β (Aβ) peptides, that subsequently form senile plaques, due to imbalance between production and clearance of Aβ. LÄS MER
