  1. 1. The release of histone proteins from cells via extracellular vesicles

    Detta är en avhandling från Umeå : Umeå University

    Författare :Uma Muthukrishnan; Umeå universitet.; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Histone; extracellular vesicles; exosomes; extracellular histones extracellular DNA; cellular stress; proteomics; ESCRT complex; Lrrn1; mid-hindbrain organizer; ovarian cancer; ascites;

    Sammanfattning : Histones are chromatin-associated proteins localized to the nucleus. However, extracellular histones are present in biofluids from healthy individuals and become elevated under disease conditions, such as neurodegeneration and cancer. LÄS MER

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Elisabeth Nikitidou; Uppsala universitet.; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; Amyloid-beta; Protofibrils; Astrocytes; Extracellular vesicles; Antibody; Neurons; Degradation; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Knowledge about the cellular mechanisms behind the initiation and propagation of Alzheimer’s disease (AD) is limited. Decades of research have focused on neuronal abnormalities in AD, but recently more attention has been given to the glial cells. LÄS MER

  3. 3. Therapeutic potential of extracellular vesicles

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Laboratory Medicine

    Författare :Oscar Wiklander; Karolinska Institutet.; Karolinska Institutet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Extracellular vesicles (EVs) are nanometer-sized, lipid membrane enclosed, vesicles that are secreted by most, if not all, cells and contain macromolecular material of the source cell including lipids, proteins and various nucleic acid species. Over the last two decades, EVs have been recognized as important mediators of cell-to-cell communication that influence both physiological and pathological conditions. LÄS MER

  4. 4. Pancreatic extracellular communication. Applications to beta cell cultures and islet amyloid polypeptide aggregation

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Diana Ribeiro; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in vitro pancreatic models; induced pluripotent stem cells; stem cell differentiation; insulin; 3D-culture; extracellular vesicles; glucose-stimulated insulin secretion; islet amyloid polypeptide; type 2 diabetes mellitus; extracellular matrix; adipose-derived stem cells; Diabetes mellitus; protein aggregation;

    Sammanfattning : Diabetes mellitus (DM) is a disease with epidemic proportions due to increased incidences worldwide, persistence of undiagnosed cases, uncontrolled forms of the disease, association with cardiovascular complications, and lack of definitive treatment options. In particular, type 2 DM (T2DM) is placing an enormous financial burden on worldwide healthcare systems that will increase in the futureThere is a need to develop physiological assay platforms that provide functionally relevant models of diabetes in order to accelerate the discovery of new treatments.

  5. 5. From single-molecule sensing to extracellular vesicles in glioma cells under stress

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Virginia Claudio; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteome; single molecule sensing; nanoplasmonics; surface plasmon resonance; exosomes; glioblastoma; extracellular vesicles; cellular stress; lipid composition;

    Sammanfattning : This thesis describes the work I conducted in two different areas, namely biomolecular sensing and quantitative cell biology. The work in the former area was focused on the optimization of plasmonic metamaterials for sensing applications, and in the latter on the characterization of extracellular vesicles released by glioblastoma cells under stress conditions.
