  1. 1. Characterization of artificial and biological lipid vesicles using TIRF and SPR

    Författare :Thomas Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; membrane permeability; chromaffin vesicle; fluorescence; total internal reflection TIRF microscopy; surface plasmon resonance SPR ; vesicle; osmotic shock; cell membrane; liposome; nanoparticle tracking analysis NTA ; large dense core vesicles LDCVs ;

    Sammanfattning : Synthetic lipid vesicles serve as important mimics of cells and the natural membranes that they are enclosed by. As such they are frequently used as simplified models of the highly complex cell membrane to aid in-depth physicochemical and biological characterization of this essential biological structure.

  3. 2. GABA in the islets of Langerhans

    Författare :Anna Wendt; Diabetes - öcellsexocytos; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; secreting systems; diabetologi; sekretion; Endokrinologi; Endocrinology; SLMV; paracrine regulation; LDCV; islets of Langerhans; autocrine regulation; GABA; diabetology;

    Sammanfattning : GABA (γ-aminobutyric acid) is a well-known inhibitory neurotransmitter in the CNS. GABA is also present at high concentrations in the insulin-producing β-cells in the islets of Langerhans, but its function there is less clear. GABA is believed to accumulate in SLMVs (synaptic-like microvesicles). LÄS MER

  4. 3. Quantitative chemical imaging to study content release from single nanovesicles

    Författare :Tho D. K. Nguyen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Exocytosis; Vesicle; Mass spectrometry imaging; Electron microscopy; Fluorescence microscopy; Electrochemical analysis; NanoSIMS;

    Sammanfattning : Cellular communication is vital for the survival of multicellular organisms. This process often relies on a highly regulated mechanism called exocytosis, which involves the release of chemical signals. During exocytosis, vesicles can fully or partially release their contents.

  5. 4. Correlative Chemical Imaging of Nanoscale Subcellular Structures

    Författare :Stefania Rabasco; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Chemical imaging can elucidate complex mechanisms, relationships, and components of biological samples. For example, it can reveal properties such as chemical composition, chemical structure, reactivity, and topography. Several imaging techniques exist, each providing different types of information.
