  1. 1. Proteolytic processing of the Alzheimer APP protein family during neuronal differentiation

    Författare :Sofia Holback; Kerstin Iverfeldt; Nigel Hooper; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APP; APLP1; APLP2; differentiation; processing; retinoic acid; secretase; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : Increased amyloid-β (Aβ) load in the brain, neurite degeneration, neuronal loss, and decreased levels of several neurotrophins are among the characteristics of Alzheimer’s disease (AD). Generation of Aβ occurs when the amyloid precursor protein (APP) is proteolytically processed by β- and γ-secretases in the amyloidogenic pathway. LÄS MER

  2. 2. Studies on gamma-secretase activity and products

    Författare :Jenny Frånberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : gamma-Secretase is a transmembrane aspartyl protease involved in processing of a multitude of functionally diverse substrates within their transmembrane domains. gamma-Secretase cleavage of the amyloid precursor protein (APP) generates the APP intracellular domain (AICD) and the amyloid beta-peptide (Abeta).

  3. 3. Identification and investigation of gamma-secretase associated proteins from brain

    Författare :Yasuhiro Teranishi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. The pathological hallmarks in the AD brain are extracellular deposition of amyloid plaques, mainly composed of the amyloid β-peptide (Aβ), and intracellular neurofibrillary tangles made of hyperphosphorylated tau.

  4. 4. A study of b-secretase cleaved Alzheimer amyloid precursor protein

    Författare :Kristina Sennvik; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease (AD) is characterized by the degeneration and loss of neurons, intracellular neurofibrillary tangles and the accumulation of extracellular senile plaques consisting mainly of beta-amyloid (A-beta). A-beta is generated from the amyloid precursor protein (APP) through sequential cleavage by proteases P- and gamma-secretase. LÄS MER

  5. 5. The amyloid-β precursor protein (APP) and its adaptor protein Fe65 : Two key players in Alzheimer’s disease

    Författare :Preeti Menon; Anna-Lena Ström; Thorsten Müller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; APP; Fe65; Meprinβ; α-secretase; APP processing; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Alzheimer’s disease (AD) is a neurodegenerative disease characterized by the abnormal accumulation and aggregation of amyloid beta (Aβ) peptides within the brain. Generation of Aβ occur when the amyloid-beta precursor protein (APP) is proteolytically processed by β- and then γ-secretase in the amyloidogenic pathway. LÄS MER
