  1. 21. Synaptic vesicle endocytosis studied in a living synapse

    Författare :Helge Gad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :synapse; synaptic vesicles; endocytosis; clathrin; calcium; dynamin; endophilin; amphiphysin; synaptojanin; microinjection; electron microscopy;

    Sammanfattning : Neurons in the central nervous system communicate by transmitting electrical signals at special sites of contact called synapses. Synapses contain neurotransmitter-filled synaptic vesicles, which fuse with the presynaptic plasma membrane. The neurotransmitter diffuses to the neighboring neuron and triggers a new electrical signal. LÄS MER

  3. 22. Vesicle-mediated and free soluble delivery of bacterial effector proteins by oral and systemic pathogens

    Författare :Bernard Thay; Jan Oscarsson; Mikael Rhen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periodontitis; Aggregatibacter actinomycetemcomitans; Staphylococcus aureus; membrane vesicles; vesicle-host cell interaction; protein delivery; molekylärbiologi; Molecular Biology;

    Sammanfattning : Periodontitis, the primary cause of tooth-loss worldwide, is a bacterially induced chronic inflammatory disease of the periodontium. It is associated with systemic conditions such as cardiovascular disease (CVD). However, pathogenic mechanisms of periodontitis-associated bacteria that may contribute to the CVD association are unclear. LÄS MER

  4. 23. On the Formation of Supported Phospholipid Bilayers

    Författare :Erik Reimhult; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vesicle adsorption; formation kinetics; SPR; QCM-D; SPB; AFM; supported lipid bilayer; supported membrane; liposome;

    Sammanfattning : Lipid bilayers are a central component of both the structure and function of biological membranes, like the one surrounding cells of living organisms. Since the lipid bilayer provides a host matrix for membrane proteins, which perform many of the specialized tasks in cells like energy, signal and material transduction, researchers have tried to develop artificial model membranes to study a variety of membrane protein functions.

  5. 24. Studies of membrane-binding proteins involved in synaptic vesicle recycling

    Författare :Fredrik Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Signaling between neurons occurs at synapses. A presynaptic nerve terminal releases neurotransmitter, which diffuses over the synaptic cleft, and binds to postsynaptic receptors. Release occurs by fusion of neurotransmitter-containing vesicles with the plasma membrane. LÄS MER

  7. 25. Membrane Orientation Studies with Polarized Light Spectroscopy

    Författare :Malin Ardhammar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lipid vesicle; membrane orientation; flow linear dichroism; oriented circular dichroism;

    Sammanfattning : Lipid vesicles are versatile tools in modern biophysical science. They can be used as models of the cell membrane, to examine permeability, stability and behavior of molecules in the bilayer. They may act as transporters in a pharmacological context, designed to deliver their cargo to a certain place in the patient. LÄS MER
