  1. 1. Investigation on Pre- and Postsynaptic Ca2+ Signaling in Neuronal Model Systems

    Författare :Jelena Krjukova; Åkerman Karl; Kukkonen Jyrki; Rydqvist Bo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; calcium; neurotransmitter release; nicotine; depolarization; G-protein coupled receptor; muscarinic; phospholipase C; m-3M3FBS; Fysiologi; Physiology; Fysiologi;

    Sammanfattning : Communication between neuronal and non-neuronal is called volume transmission when the released neurotransmitter (NT) acts via diffusion and affects several target cells. Both the neurosecretory and postsynaptic cell responses are linked to [Ca2+]i elevations. LÄS MER

  2. 2. Ethanol-mediated effects on astroglial cells in primary culture. With a focus on acute changes in intracellular Ca2+, cell volume, actin filaments, and gap junction coupling

    Författare :Louise Adermark; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astrocyte; BaCl2; cell swelling; fura-2; furosemide; ouabain; scrape loading; volume estimation;

    Sammanfattning : The astroglial cells are abundant in the central nervous system (CNS), where they control and regulate the homeostasis of the extracellular milieu. A change in astroglial cell volume, mediated through activation of neuroactive substances or changes in osmolarity, leads to changes in the size and geometry of the extracellular space volume, which could affect the diffusion and concentration of neuroactive substances.

  3. 3. Organic bioelectronic devices to control cell signalling

    Författare :Karin Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The nervous system consists of a network of specialized cells that coordinate the actions of the body by transmitting information to and from the brain. The communication between the nerve cells is dependent on the interplay of both electrical and chemical signals. LÄS MER

  4. 4. Strategies to explore the membrane proteome of a cell

    Författare :Gianluca Maddalo; Leopold L. Ilag; Peter James; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteomics; Escherichia coli; Enterococcus faecalis; Synechocystis; Mass Spectrometry; BN SDS-PAGE; FT-ICR-MS; Myelin P2 protein; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : The cell envelope plays key roles in numerous processes such as maintaining cellular integrity, communication with other cells, signal transduction, maintenance of cellular homeostasis, and regulation of the traffic of molecules between the cell and the extracellular milieu. Essential membrane components in many of these processes are proteins. LÄS MER

  5. 5. Bacterial physiology and its role in antibiotic refractoriness

    Författare :Spyridon Gkotzis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The pathological outcome of a bacterial infection depends on the interplay among the host’s innate defenses, the virulence arsenal of the pathogen and antibiotic treatment strategies. Understanding this interplay will provide mechanistic insights on antibiotic pharmacodynamics and bacterial pathogenesis, and set the stage for the development of novel therapeutic interventions.
