  1. 1. 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.

  2. 2. 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

  3. 3. The cell line RN33B transplanted to adult retina

    Author : Anita Blixt Wojciechowski; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oftalmologi; host glial response; Ophtalmology; differentiation; migration; proliferation; survival; immunosuppression; RN33B; brain-derived precursor cells; retinal degeneration; subretinal transplantation;

    Abstract : The thesis describes the neural precursor cell line RN33B transplanted subretinally to adult healthy and young dystrophic rat retina. The cell line is generated from E12,5 rat raphe nucleus and transduced with the temperature sensitive mutant of the Simian Virus 40 (SV40) large T-antigen. READ MORE

  4. 4. 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

  5. 5. 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
