Inhibition Of Injury-Induced Cell Proliferation In The Dentate Gyrus Impairs Cognitive Recovery Following Traumatic Brain Injury, Teresa Daniels
Inhibition Of Injury-Induced Cell Proliferation In The Dentate Gyrus Impairs Cognitive Recovery Following Traumatic Brain Injury, Teresa Daniels
Theses and Dissertations
Traumatic brain injury (TBI) induces a robust cellular proliferative response among neural stem/progenitor cells (NS/NPCs) in the dentate gyrus of the hippocampus. This proliferative effect is thought to contribute to the innate cognitive recovery observed following TBI. Inhibition of hippocampal neurogenesis impairs cognitive function. Furthermore, enhancement of injury-induced hippocampal neurogenesis via intraventricular administration of basic fibroblast growth factor (bFGF) improves cognitive function in animals following TBI. In this experiment, we investigated the direct association between injury-induced hippocampal neurogenesis and cognitive recovery utilizing an antimitotic agent, arabinofuranosyl cytidine (Ara-C). In this study, adult rats received a moderate lateral fluid percussion injury …
The Effect Of Minocycline Treatment On Cell Proliferation And Neurogenesis In The Hippocampus In Young And Aged Brains Following Traumatic Brain Injury, Ashley Harvin
Theses and Dissertations
Following traumatic brain injury, there is an enhanced cell proliferative and neurogenic response in the young adult hippocampus, which may be associated with innate cognitive recovery. However, in the aged brain, an increased level of inflammatory cell responses was observed following injury concomitant to decreased hippocampal neurogenesis and cognitive recovery in the aging population. This suggests that excessive inflammation produced in the injured aging brain has a detrimental effect on neurogenesis and cognitive function. In this study, we examined the effect of anti-inflammatory treatment with minocycline on cell proliferation and generation of new neurons in the dentate gyrus (DG) of …
The Effects Of Bfgf Treatment In The Aged Brain Following Traumatic Brain Injury, Michael Zeigler
The Effects Of Bfgf Treatment In The Aged Brain Following Traumatic Brain Injury, Michael Zeigler
Theses and Dissertations
The mature mammalian brain continually generates new neurons in the subventricular zone and hippocampus throughout life. Adult neurogenesis in the hippocampus is associated with hippocampal-dependent learning and memory function. During aging, this endogenous neurogenic potential is reduced which is accompanied by decreased cognitive function seen in the aging population. We have previously found that the injured adult brain shows heightened levels of endogenous neurogenesis and this response is associated with innate cognitive recovery. We have also found that basic fibroblast growth factor (bFGF), a potent neurotrophic polypeptide, can enhance injury-induced hippocampal neurogenesis and improve cognitive recovery following TBI. In this …
