Improving Peripheral Nerve Regeneration Through Rehabilitation And Biomaterial-Based Drug Delivery Strategies, Yunfan Kong
Improving Peripheral Nerve Regeneration Through Rehabilitation And Biomaterial-Based Drug Delivery Strategies, Yunfan Kong
Theses & Dissertations
Peripheral nerve injury (PNI) is a common problem worldwide, with trauma being a common cause. PNI can lead to loss of sensory and motor functions, chronic neuropathic pain, and mental health issues, significantly impacting patients' family life, work, and social situation. Recent studies revealed that beyond the topical injury site at peripheral nerves, PNIs can also induce dysfunctions in the central nervous system (CNS) by causing maladaptive plasticity, which will result in exaggeration and exacerbation of the pathological condition caused by primary injuries. The common therapy strategies for PNI treatment are using sutures, nerve autografts or conduits in cases requiring …
The Opposing Roles Of Glun2c And Glun2d Nmda Receptor Subunits In Modulating Neuronal Oscillations, Zhihao Mao
The Opposing Roles Of Glun2c And Glun2d Nmda Receptor Subunits In Modulating Neuronal Oscillations, Zhihao Mao
Theses & Dissertations
N-methyl-D-aspartate receptors (NMDARs) are ligand-gated ion channels consisting of two GluN1 subunits and two other subunits from among GluN2A-2D and GluN3A-3B subunits. NMDARs play critical roles in synaptic plasticity, learning and memory, and higher brain function such as cognition and perception. Dysfunction of NMDARs (hyper-function and hypo-function of NMDARs) are related to various diseases, including stroke, schizophrenia, Alzheimer’s disease, and others. However, to date, NMDARs antagonists have mostly failed in clinical trials due to adverse effects.
NMDARs antagonists replicate the core symptoms of schizophrenia which may underlie its ability to alter neuronal oscillations in the neural circuitry of different brain …
Effects Of Gm-Csf On Dendritic Cells And Regulatory T Cells In Parkinson’S Disease Patients And Models Of Parkinson’S Disease, Charles Schutt
Effects Of Gm-Csf On Dendritic Cells And Regulatory T Cells In Parkinson’S Disease Patients And Models Of Parkinson’S Disease, Charles Schutt
Theses & Dissertations
Parkinson’s disease (PD) is the most common neurodegenerative movement disorder. Pathologically, loss of nigrostriatal neurons and dopamine released by these neurons are responsible for PD motor symptoms. During PD, activation of resident microglia and infiltrating lymphocytes leads to progressive neuroinflammation and reduction in the number and function of regulatory immune cells. Neuroinflammation contributes to progressive neurodegeneration and declining motor function. Reducing neuroinflammation is the target for novel PD therapeutics. Our goal is to increase the number and function of regulatory T cells (Tregs) in PD patients to decrease neuroinflammation and reduce PD symptoms. One potential therapy is granulocyte-macrophage colony stimulating …
Global Gene Expression Profiling Of Healthy Human Brain And Its Application In Studying Neurological Disorders, Simarjeet K. Negi
Global Gene Expression Profiling Of Healthy Human Brain And Its Application In Studying Neurological Disorders, Simarjeet K. Negi
Theses & Dissertations
The human brain is the most complex structure known to mankind and one of the greatest challenges in modern biology is to understand how it is built and organized. The power of the brain arises from its variety of cells and structures, and ultimately where and when different genes are switched on and off throughout the brain tissue. In other words, brain function depends on the precise regulation of gene expression in its sub-anatomical structures. But, our understanding of the complexity and dynamics of the transcriptome of the human brain is still incomplete. To fill in the need, we designed …
Target Validation And Pharmacological Characterization Of Novel Nmdar Modulators, Kiran Sapkota
Target Validation And Pharmacological Characterization Of Novel Nmdar Modulators, Kiran Sapkota
Theses & Dissertations
The N-methyl-D aspartate receptors (NMDARs) are ligand-gated ion channels, which play important roles in learning and memory. Excessive activity of NMDARs is implicated in damage due to stroke and neurodegenerative diseases, whereas hypoactivity of NMDARs contributes to schizophrenia. The initial goal of my dissertation is to evaluate the potential role of the GluN2D-containing NMDARs in neuropathological, behavioral and cognitive alterations associated with schizophrenia and characterize the pharmacology and mechanisms of action of NMDAR modulators which could potentially be used to modulate these receptors in schizophrenia.
A subanesthetic dose of the NMDAR antagonist ketamine elicits symptoms of schizophrenia. This property led …
Compensatory Mechanisms And T Cell Migration In Mouse Models Of Dopaminergic Loss, Kristi M. Anderson
Compensatory Mechanisms And T Cell Migration In Mouse Models Of Dopaminergic Loss, Kristi M. Anderson
Theses & Dissertations
Parkinson’s disease (PD) is the most common neurodegenerative movement disorder and second most common neurodegenerative disorder. PD is characterized by the selective loss of dopaminergic neurons and dopamine neurotransmitter within the substantia nigra and termini in the striatum. Progressive loss of dopaminergic neurons occurs over many years in PD, and by the time movement disorder symptoms manifest, up to 50-70% of dopaminergic neurons have been lost. Several aspects of PD pathology have been described in detail, but a better understanding of PD progression is needed to develop more efficient treatments.
Motor symptoms associated with PD do not manifest until significant …
Development Of Manganese-Enhanced Magnetic Resonance Imaging (Memri) Methods To Study Pathophysiology Underlying Neurodegenerative Diseases In Murine Models, Aditya N. Bade
Theses & Dissertations
Manganese-enhanced magnetic resonance imaging (MEMRI) opens the great opportunity to study complex paradigms of central nervous system (CNS) in freely behaving animals and reveals new pathophysiological information that might be otherwise difficult to gain. Due to advantageous chemical and biological properties of manganese (Mn2+), MEMRI has been successfully applied in the studies of several neurological diseases using translational animal models to assess comprehensive information about neuronal activity, morphology, neuronal tracts, and rate of axonal transport. Although previous studies highlight the potential of MEMRI for brain imaging, the limitations concerning the use of Mn2+ in living animals and …
