  2. 1. Processing of the amyloid precursor protein and its paralogues amyloid precursor-like proteins 1 and 2

    Author : Linda Adlerz; Kerstin Iverfeldt; Richard Cowburn; Stockholms universitet; []

    Abstract : Alzheimer’s disease (AD) is a neurodegenerative disorder which is histopathologically characterised by amyloid plaques and neurofibrillary tangles. Amyloid plaques consist of the amyloid β-peptide (Aβ) that can form aggregates in the brain. Aβ is generated from the amyloid precursor protein (APP) through proteolytic cleavage. READ MORE

  4. 2. In vitro modelling of tau phosphorylating kinases : emphasis of Cdk5

    Author : Anne Jämsä; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The main hallmarks of Alzheimer’s disease (AD) are extracellular deposits of betaamyloid (Aβ) and intracellular neurofibrillary tangles (NFT) composed of highly phosphorylated tau protein. Abnormal hyperphosphorylation of tau is the most deleterious step in NFT formation making the use of kinase inhibitors an attractive treatment possibility in AD. READ MORE

  5. 3. SNAP-25 and Cdk5 as exocytotic regulators : consequences for synaptic function and insulin release

    Author : Jenny Johansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The process by which cells release substances through fusion of vesicles with the plasma membrane is called exocytosis. Regulated exocytosis needs to be tightly controlled in order to respond to the large variation in stimuli and demands for release of neurotransmitters, peptides and hormones. READ MORE

  6. 4. Molecular mechanisms regulating exocytosis : studies of insulin secretion and neurotransmitter release

    Author : Lena Lilja; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Cdk5; cell line; DARPP-32; dephosphorylation; exocytosis; inhibitor-1; insulin; islet; kinase; munc18; myotube; p35; p39; phosphatase; phosphorylation; PP1; presynaptic mechanisms; secretion; subcellular localization.;

    Abstract : In order to achieve normal physiology the secretion of hormones and neurotransmitters needs to be firmly controlled. The basic molecular machinery mediating regulated exocytosis of hormones and neurotransmitters is in principal revealed, but knowledge about how the individual components are spatially and temporarily coordinated is limited.

  7. 5. Components controlling vesicle trafficking and regulated exocytosis in pancreatic beta-cells

    Author : Slavena Andrea Mandic; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Regulated exocytosis is a sophisticated, well-organized and conserved multistage process underlying release of both neurotransmitters and hormones. Exocytosis is mediated by SNARE proteins that act at the center stage by forming a SNARE complex with the intrinsic capability to execute membrane fusion. READ MORE
