  1. 11. 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

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

    Sammanfattning : 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. LÄS MER

  3. 12. Pituitary adenylate cyclase activating polypeptide : Expression and neurotrophic activity in the rat brain

    Författare :Ylva Skoglösa; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; in situ hybridisation; rat; TBI; BDNF; NGF; GDNF; PACAP; PRI; TUNEL; apoptosis; CNS; PNS; neuropeptides; neurotrophic factors; reactive oxygen species; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Neurotrophic factors play an important role in regulating naturally occurring cell death during neurogenesis. In addition to classical neurotrophic factors, some neurotransmitters and neuropeptides have been shown to exhibit neurotrophic activities. LÄS MER

  4. 13. Opioids regulate proliferation of neural progenitors. A study on the effects of opioids on adult rat hippocampal progenitors in vitro and in vivo

    Författare :Anders I. Persson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Opioid; brain; hippocampus; rat; neurogenesis; progenitor; stem cell; b-endorphin; calcium; MAPK;

    Sammanfattning : The opioid receptors were among the first pharmacologically described brain receptors. These opioid receptors have thereafter been shown to mediate effects on proliferation and differentiation in both the embryonal and adult central nervous system. LÄS MER

  5. 14. Ischemic Tolerance and Cell Signaling in the Rat Brain

    Författare :Mehrdad Shamloo; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preconditioning; cell death; tyrosine phosphorylation; tolerance; ERK; Calpain; CaMKII; PKC; protection; Brain; ischemia; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : A brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. LÄS MER
