  1. 1. Intermediate-sized (skeletin) filaments of heart Purkinje fibres : an investigation into their morphology, composition and function

    Författare :Anders Eriksson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : .... LÄS MER

  3. 2. The Role of Reactive Astrocytes in Brain Ischemia and Neurotrauma

    Författare :Lizhen Li; Göteborgs universitet; []
    Nyckelord :astrocytes; intermediate filaments; GFAP; vimentin; reactive gliosis; brain ischemia; neurotrauma;

    Sammanfattning : Astrocytes are the most abundant cell type in the central nervous system (CNS) and increasing evidence now suggests that they play an active role in various brain functions. Astrocytes are involved in the induction and maintenance of the blood brain barrier, as well as the induction and stabilization of neuronal synapses. LÄS MER

  4. 3. The effect of astrocytes and reactive gliosis on neurogenesis and astrogenesis in mice

    Författare :Åsa Widestrand; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astrocytes; intermediate filaments; neural stem cells; neurogenesis; astrogenesis; hippocampus;

    Sammanfattning : Astrocytes are the most common cell type in mammalian central nervous system (CNS). Glial fibrillary acidic protein (GFAP) and vimentin constitute intermediate filaments (known also as nanofilaments), a part of the cytoskeleton, in astrocytes. LÄS MER

  5. 4. Salivary gland neoplasms : studies on the cytoskeleton, the secretory apparatus and the nuclear DNA content

    Författare :Hans Gustafsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salivary gland neoplasms; intermediate filaments; immuno- histochemistry; ultrastructure; DNA; development; histogenesis; progno¬sis;

    Sammanfattning : The heterogeneity of salivary gland neoplasms have made classification and prognostication of these tumours sometimes difficult, and the in­troduction of techniques, such as enzyme and carbohydrate histochemis­try and electron microscopy have only to a certain extent increased our knowledge in these respects. In the present study immunohistochemical methods have been used to identify intermediate filament proteins (IFP) in normal fetal and adult parotid glands, as well as in salivary neo­plasms. LÄS MER

  7. 5. The importance of astroglial cells in ischemia, regeneration and angiogenesis

    Författare :Andrea Lundkvist; Göteborgs universitet; []
    Nyckelord :astrocytes; Müller cells; retina; intermediate filaments; GFAP; vimentin; angiogenesis; VEGF-A; guidance; matrix-metalloprotease;

    Sammanfattning : Astrocytes in the CNS communicate with both neurons and blood vessels. In many CNS pathologies, astrocytes respond by becoming reactive. Whether their performance at this stage is beneficial or detrimental for CNS function is unclear. LÄS MER
