  1. 1. New neurons and astrocytes in the adult brain. Studies on adult rat neural progenitors in vivo and in vitro with special reference to the effects of IGF-I and CNTF regarding proliferation and lineage determination

    Author : Maria A I Åberg; Göteborgs universitet; []
    Keywords : Brain; hippocampus; rat; neurogenesis; progenitor cell; stem cell; ciliary neurotrophic factor; insulin-like growth factor-I; PI3-K; MAPK.;

    Abstract : The hippocampal dentate gyrus in several species, including man, continues to produce new neurons and glial cells in adulthood. The generation of new neurons and glial cells in the adult hippocampus is under strict regulation. Two major events of significance for cell genesis from progenitor cells are proliferation and lineage determination. READ MORE

  2. 2. Spinal motoneurons and molecules related to neurotrophic function after axon injury

    Author : Henrik Hammarberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : immunohistochemistry; in situ hybridization; spinal cord; motoneuron; axotomy; survival; regeneration; MHC 1; leukocyte; cell culture; mRNA expression;

    Abstract : The capacity of motoneurons to survive and regenerate new axons after injuries such as axotomy depends on a great variety of parameters. After sciatic nerve transection (SNT) in adult rats and to some extent after a ventral funiculus lesion (VFL), many cells survive and regeneration is highly prioritized. READ MORE

  3. 3. On the actions of neurotrophic factors on the chromaffin cells of the adrenal medulla

    Author : Petter Förander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Neural crest; chromaffin cells; neurotrophic factors; NGF; NT-3; NT4; CNTF; GDNF; TGFß; FGF2; glucocorticoids; Intra oculartransplantation ; primary cultures; neurite outgrowth;

    Abstract : Chromaffin cells producing adrenaline or noradrenaline are the predominant cell type in the adrenal medulla, but ganglion cells and Schwann cells are also present. All cells of the adrenal medulla are derived from the neural crest, which is a transient neuroectoderm-derived embryonic structure. READ MORE

  4. 4. Genetic aspects on schizophrenia and cerebrospinal fluid monoamine metabolites : focus on association studies with candidate genes

    Author : Erik Jönsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : association study; schizophrenia; DNA polymorphisms; dopamine receptors DRD2; DRD3; DRD4 ; tyrosine hydroxylase; tryptophan hydroxylase; catechol-O-methyltransferase; neurotrophin-3; ciliary neurotrophic factor; healthy subjects; cerebrospinal fluid;

    Abstract : Schizophrenia is a syndrome with psychotic symptoms. The pathogenesis of schizophrenia most likely reflects brain abnormalities and heritable components are present. The principal objective of the present thesis was to investigate some possible genetic influences in the genesis or pathophysiology of schizophrenia. READ MORE

  5. 5. Stem cell differentiation, plasticity and regenerative mechanisms in the cholinergic system : implications for Alzheimer’s disease

    Author : Mats Nilbratt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alzheimer´s disease; amyloid precursor protein; cholinergic differentiation; human embryonic stem cells; neural precursor; nicotinic acetylcholine receptor; neurotrophic factor; radial glial cells; transplantation;

    Abstract : Stem cells are immature cells with self-renewal capacity. They are able to differentiate into multiple lineages that may serve as a source of expandable cells for various applications. READ MORE
