  1. 1. Astrocytes, reactive gliosis and CNS regeneration

    Author : Ulrika Wilhelmsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : CNS regeneration; astrocytes; reactive gliosis; intermediate filaments;

    Abstract : The regenerative capacity in the adult central nervous system (CNS) is very limited, and the glial cells have been implicated in the inhibition of CNS regeneration. In essentially all CNS pathologies, astrocytes are activated and this process is known as reactive gliosis. READ MORE

  2. 2. Interaction between nerve fiber formation and astrocytes

    Author : Sanazalsadat Hashemian; Ingrid Strömberg; Elisabet Åkesson; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; nerve fiber outgrowth; astrocytes; ventral mesencephalon; spinal cord; CSPG; CD47;

    Abstract : Parkinson’s disease, the second most common neurodegenerative disorder,is characterized by loss of nigrostriatal dopaminergic neurons. To date,there is no defined cause and cure for the disease. An ideal treatmentstrategy is to replace the lost neurons by transplanting fetal dopaminergicneurons to the brain of parkinsonian patients.

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

    Author : Elisabeth Nikitidou; Anna Erlandsson; Martin Ingelsson; Gunnar K. Gouras; Uppsala universitet; []
    Keywords : Alzheimer’s disease; Amyloid-beta; Protofibrils; Astrocytes; Extracellular vesicles; Antibody; Neurons; Degradation; Medicinsk vetenskap; Medical Science;

    Abstract : 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. READ MORE

  4. 4. The Role of Reactive Astrocytes in Brain Ischemia and Neurotrauma

    Author : Lizhen Li; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : astrocytes; intermediate filaments; GFAP; vimentin; reactive gliosis; brain ischemia; neurotrauma;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
