    Sammanfattning : Biological variations are being explored at ever-increasing rates through the rapid advancement of analytical techniques. Techniques like massively parallel sequencing empower scientists to accurately differentiate individuals’ genetic compositions, cellular functionalities, and healthy tissue from diseased. LÄS MER

  3. 2. Epigenetic influence on cardiovascular protective mechanisms in vivo: explorations of t-PA release and extracellular vesicle genetic content

    Författare :Kristina Svennerholm; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial ischemia; epigenetics; histone deactylase inhibition; t-PA; extracellular vesicles; ischemic preconditioning;

    Sammanfattning : ABSTRACT Background: Ischemic heart disease is one of the leading causes of death globally. This thesis explores endogenous mechanisms protecting against myocardial ischemia in context of epigenetics (changes in gene activity not caused by changes in DNA sequences). LÄS MER

  4. 3. Development of Techniques for Characterization, Detection and Protein Profiling of Extracellular Vesicles

    Författare :Sara Cavallaro; Jan Linnros; Apurba Dev; Hakho Lee; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular vesicles; streaming current; fluorescence microscopy; atomic force microscopy; scanning electron microscopy; protein profiling; size profiling; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Nanosized extracellular vesicles (EVs, ∼30-2000 nm) have emerged as important mediators of intercellular communication, offering opportunities for both diagnostics and therapeutics. In particular, small EVs generated from the endolysosomal pathway (∼30-150 nm), referred to as exosomes, have attracted interest as a suitable biomarker for cancer diagnostics and treatment monitoring based on minimally invasive liquid biopsies.

  5. 4. Purification, profiling and bioengineering of extracellular vesicles

    Författare :Giulia Corso; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The nano-sized membrane enclosed extracellular vesicles (EVs) transfer macromolecular information in the form of proteins, nucleic acids and lipids across cells. They are important mediators of cell-to-cell communication, but their relatively small size makes EV isolation and down-stream analysis challenging. LÄS MER

  7. 5. New Approaches for Chemical Analysis of Single Cells and Vesicles

    Författare :Johan Dunevall; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrochemistry; Analytical chemistry; Chemistry; Exocytosis; Catecholamines;

    Sammanfattning : Exocytosis is the major cell-to-cell communication process in the nervous system, involving the conversion of an electrical signal (e.g. action potential) to a chemical one. Signaling molecules like neurotransmitters, hormones and/or peptides are stored in vesicles inside the cell. LÄS MER
