Investigating Neuroinflammation And Demyelination In The Nervous System Of Twitcher Mice By The Use Of Immunohistochemistry, Irene Wilson
Investigating Neuroinflammation And Demyelination In The Nervous System Of Twitcher Mice By The Use Of Immunohistochemistry, Irene Wilson
Natural Sciences and Mathematics | Biological Sciences Master's Theses
Neuroinflammation and demyelination are the hallmark lesions of the Twitcher mouse—the model of Krabbe Disease. By analyzing hemibrains and sciatic nerves via immunohistochemistry, we supported the microglial hypothesis that early activation of microglial cells, macrophages, and globoid cells in the nervous system of Twitcher mice results in specific cellular polarization states that may contribute to myelin loss. The influx of activated macrophages seen in both the central and peripheral nervous systems at days 21 and 17, respectively, accounted for this polarization. Using selected M1 and M2 markers, YKL-40, and GPNMB and CD206, respectively, we proved that microglial cells and macrophages …

The Effects Of Two Novel Anti-Inflammatory Compounds On Prepulse Inhibition And Neural Microglia Cell Activation In A Rodent Model Of Schizophrenia, Heath W. Shelton
Electronic Theses and Dissertations
Recent studies have shown elevated neuroinflammation in a large subset of individuals diagnosed with schizophrenia. A pro-inflammatory cytokine, tumor necrosis factor-alpha (TNFα), has been directly linked to this neuroinflammation. This study examined the effects of two TNFα modulators (PD2024 and PD340) produced by our collaborators at P2D Bioscience, Inc., to alleviate auditory sensorimotor gating deficits and reduce microglial cell activation present in the polyinosinic:polycytidylic (Poly I:C) rodent model of schizophrenia. Auditory sensorimotor gating was assessed using prepulse inhibition and microglial activation was examined and quantified using immunohistochemistry and confocal microscopy, respectively. Both PD2024 and PD340 alleviated auditory sensorimotor gating deficits …

Dissertations, Theses, and Capstone Projects
Methamphetamine (METH) is a strong psychostimulant and its exposure can lead to serious neurological complications. METH-induced neuronal injury is the result of a complex interplay of different factors including dopamine (DA) overflow, oxidative stress and neuroinflammation. Although the mechanisms of METH-induced neurotoxicity have been extensively studied, there is still no effective therapeutic treatment. Therefore, it is essential to study potential drug candidates that can treat METH-induced neurotoxicity. Green tea extract, epigallocatechin gallate (EGCG), has emerged as a neuroprotective agent that can protect against several neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases. Recently, our lab has shown that EGCG prevents …
Role Of Sarm1 In Chronic Immune-Mediated Central Nervous System Inflammation, Kenneth E. Viar Ii
Role Of Sarm1 In Chronic Immune-Mediated Central Nervous System Inflammation, Kenneth E. Viar Ii
Theses and Dissertations
SARM1 is an injury-induced nicotinamide adenine dinucleotide nucleosidase (NADase) that was previously shown to promote axonal degeneration in response to traumatic, toxic, and excitotoxic stressors. This raises the question of whether a SARM1-dependent program of axonal degeneration is central to a common pathway contributing to disease burden in neurological disorders. The degree to and mechanism by which SARM1 inactivation decreases the pathophysiology of such disorders is of interest to establish the rationale to pursue SARM1 as a therapeutic target. In this study, we compare the course and pathology of experimental autoimmune encephalomyelitis (EAE) in Sarm1-knockout (KO) mice and wild-type …
