2. 1. Altered cell signaling linked to neurodegeneration : Studies on scrapie-infected neuroblastoma cells and activated microglia

   Author : Christina Svensson; Tiit Land; Gianluigi Forloni; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prion disease; Inflammation; MAPK; Microglia activation; Neuroblastoma; Neurochemistry; Neurokemi; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Abstract : Prion diseases are neurodegenerative disorders that can affect humans and animals. The underlying event is a conformational change of the normal cellular prion protein (PrPC) into an aberrant isoform termed PrP-scrapie (PrPSc). PrPSc is thought to lead to neurodegeneration and activation of glial cells. READ MORE

4. 2. PET and the Multitracer Concept: An Approach to Neuroimaging Pathology

   Keywords : Neurosciences; PET Positron Emission Tomography ; multitracer; neuroimaging pathology; astrocytes; microglia; neurodegeneration; amyloid; AD; CJD; PD; Neurovetenskap;

   Abstract : Patients suffering from different forms of neurodegenerative diseases, such as: Creutzfeldt Jacob Disease (CJD), Alzheimer disease (AD), mild cognitive impairment (MCI), frontotemporal dementia and Parkinson’s disease (PD) were examined with Positron Emission Tomography (PET) and the combination of different radiotracers: 15O-water, N-[11C-methyl]-L-deuterodeprenyl (DED), [18F] 2-fluorodeoxyglucose: (FDG), N-methyl-[11C]2-(4-methylaminophenyl)-6-hydroxybenzothiazole (PIB) and L-[11C]-3,4-dihydroxiphenyl-alanine (DOPA). The radiotracers and the combinations of different radiotracers were selected with the intention to detect, in the brain, patterns of neuronal dysfunction, astrocytosis, axon degeneration or protein aggregation (amyloid), in the brain which are pathognomonic for specific diseases and may contribute to improve clinical differential diagnoses.

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

   Author : Malin Samuelsson; Kerstin Iverfeldt; Piet Eikelenboom; Stockholms universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Role of Neuroinflammation in Parkinson's Disease and Related Disorders

   Author : Edoardo Brandi; Neural plasticitet och reparation; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha synuclein; Preformed fibrils; Microglia; Astrocyte; Neuroinflammation; Lipopolysaccharides; Parkinson Disease; Lewy Body Dementia; Multiple system atrophy; Synucleinopathies;

   Abstract : Synucleinopathies are neurodegenerative disorders characterized by intracellular protein aggregates, progressive neurodegeneration, and neuroinflammation. Alpha-synuclein (a-syn) is the principal component of intracellular aggregates and can be modified by several mutations and post-translational modifications (PTMs), which can alter the protein structure affecting its aggregation, toxicity, and ability to spread.

7. 5. On inflammatory cytokines and β-amyloid peptides in acute and chronic neurodegeneration

   Author : Roya Tehranian; Gianluigi Forloni; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inflammation; Cytokines; Amyloid; Peptides; Nerve degeneration; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Abstract : Insults to the brain as well as neurodegenerative diseases are known to elicit inflammatory responses. Inflammation in the brain can on one hand initiate processes that are harmful to the injured tissue and exacerbate the damage, leading to neuronal degeneration and glial activation, and on the other hand activate processes that may be necessary for repair mechanisms and regeneration.
