  1. 6. About hyaluronan in the hypertrophic heart : studies on coordinated regulation of extracellular matrix signalling

    Författare :Urban Hellman; Anders Waldenström; Stellan Mörner; Anna Engström-Laurent; Lena Jonasson; Umeå universitet; []
    Nyckelord :hyaluronan; hyaluronan synthases; gene expression; extracellular matrix; cardiac hypertrophy; rat wistar; male ; cardiomyocytes; growth factors; fibroblasts; microvesicles; exosomes; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Background. Myocardial hypertrophy is a risk factor for cardiovascular morbidity and mortality. Independent of underlying disease, the cardiac muscle strives in different ways to compensate for an increased workload. This remodelling of the heart includes changes in the extracellular matrix which will affect systolic and diastolic cardiac function. LÄS MER

  3. 7. Cellular responses to amyloid-beta protofibrils : Focus on astrocytes, extracellular vesicles and antibody treatment

    Författare :Elisabeth Nikitidou; Anna Erlandsson; Martin Ingelsson; Gunnar K. Gouras; Uppsala universitet; []
    Nyckelord :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

  4. 8. Studies on extracellular matrix proteins in vascular disease

    Författare :Åsa Ström; Kärlväggsbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; smooth muscle cells; osteopontin; extracellular matrix; atherosclerosis;

    Sammanfattning : The composition of the vascular extracellular matrix (ECM) is altered during remodeling conditions such as atherosclerosis. The changed ECM regulates events that are important for the progression of disease including smooth muscle cell (SMC) behaviour and collagen fiber formation. LÄS MER

  5. 9. Fluid biomarkers of extracellular matrix remodelling across neurological diseases

    Författare :Karolina Minta; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; biomarker; extracellular matrix; idiopathic normal pressure hydrocephalus; immunoassay; mass spectrometry; radiation-induced brain injury; traumatic brain injury; vascular dementia;

    Sammanfattning : Neurological diseases constitute a major health and socioeconomic issue. Despite an enormous amount of research going on globally, the prevalence and mortality of neurological disorders are still rising. LÄS MER

  7. 10. Role of extracellular ATP in immune mechanisms against infections

    Författare :Lalitha Tadala; Andrea Puhar; Sara I Wilson; Bernt Eric Uhlin; Mikael Sellin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extracellular ATP; invasive bacteria; Shigella; Listeria; plasma membrane ruffle; PIEZO1; infection; immune response; Hanta virus; molekylär cellbiologi; molecular cell biology;

    Sammanfattning : Inflammation is driven either by infection with pathogens or sterile stimuli, such as tissue damage or autoimmune diseases. Upon tissue damage, ATP is released passively from the dead or compromised cells. During stress, ATP can be secreted from the cells. Extracellular ATP (eATP) acts as an endogenous danger signal.
