    Sammanfattning : Iron is essential for all living organisms, from bacteria to man for a broad variety of biological functions, including oxygen transport and DNA synthesis. However, iron can also be toxic, due to its involvement in the formation of highly reactive oxygen species through Fenton chemistry. LÄS MER

    Sammanfattning : Alzheimer´s disease (AD) is the most common of the progressive neurodegenerative disorders and is characterized by the formation of Aβ deposits, neurofibrillary tangles and loss of neurons. Additional features of the disease are inflammation, increased oxidative stress and modified iron metabolism. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 5. Changed iron metabolism and iron toxicity in scrapie-infected neuroblastoma cells

    Författare :Sandra Zetterström Fernaeus; Tiit Land; Gaetano Cairo; Stockholms universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prion disease; oxidative stress; iron metabolism; Neurochemistry; Neurokemi;

    Sammanfattning : Reactions and interactions of iron and oxygen can be both beneficial and detrimental to cells and tissues. Iron is mainly found in our blood where it functions as a mediator in the transport of oxygen to the cells and is further vital for the cellular respiration reducing the oxygen to water. LÄS MER
