Characterizing The Function Of B Cells That Accumulate In The Inflamed Central Nervous System In Anti-Myelin Autoimmunity, Lika Chowdhury
Characterizing The Function Of B Cells That Accumulate In The Inflamed Central Nervous System In Anti-Myelin Autoimmunity, Lika Chowdhury
Electronic Thesis and Dissertation Repository
While the role of autoimmune T cells has been extensively studied in anti-myelin
autoimmunity, little is known about the function of B cells in multiple sclerosis (MS), a chronic inflammatory disease of the central nervous system (CNS). B cells form clusters with T cells in the meninges directly adjacent to demyelinating lesions. Previous studies have shown that disease progression is dependent on the depletion of specific populations of B cells, but it is not clear which contributes to pathology or how. The purpose of this thesis is to characterize the population of meningeal B cells to determine how they differ …
Med12 Is A Critical Regulator Of Neural Crest Lineage And Nervous System Myelination, Fatma Betul Aksoy Yasar
Med12 Is A Critical Regulator Of Neural Crest Lineage And Nervous System Myelination, Fatma Betul Aksoy Yasar

The Mediator complex (MED) is a multi-subunit protein complex integral to the eukaryotic transcription machinery. MED12 is a Cdk8- regulatory kinase module subunit directly implicated in human disease and is genetically altered in neurological disease and cancer. Numerous attempts at generating an in vivo system to study the role of Med12 failed due to embryonic lethality associated with germline or developmental disruption of Med12 gene. To understand the cellular and molecular processes associated with its role in disease, we generated multiple mouse models with targeted depletion of MED12 in distinct cellular lineages. Our genetically engineered models with induced and conditional …
Morphine-Induced Hyperactivity Is Attenuated By Intra-Accumbens Administration Of The Highly-Selective Dopamine D3 Receptor Antagonist Vk4-40, Mansi Patel, Desta M. Pulley, Daniel Manvich
Morphine-Induced Hyperactivity Is Attenuated By Intra-Accumbens Administration Of The Highly-Selective Dopamine D3 Receptor Antagonist Vk4-40, Mansi Patel, Desta M. Pulley, Daniel Manvich

Opioids exert their abuse-related effects by enhancing dopamine (DA) neurotransmission within the brain’s mesolimbic reward system, a neural projection involving DA neurons in the ventral tegmental area (VTA) that project to medium spiny neurons within the nucleus accumbens (NAc). Mu (MOR) are expressed by several populations of GABAergic neurons that tonically inhibit VTA DA neurons. By inhibiting these GABAergic neurons in a MOR-dependent manner, opioids indirectly enhance DA neurotransmission via disinhibition of DAergic neurons. Accumulating evidence indicates that selective pharmacological antagonism of the dopamine D3 receptor (D3R) attenuates the abuse-related effects of several opioids, but the neurobiological mechanisms mediating this …
Investigating The Role Of The Basolateral Amygdala Plays In The Incubation Of Cue-Induced Cocaine Seeking Behavior, Claire Marie Corbett
Investigating The Role Of The Basolateral Amygdala Plays In The Incubation Of Cue-Induced Cocaine Seeking Behavior, Claire Marie Corbett
Graduate School of Biomedical Sciences Theses and Dissertations
Cocaine use disorder is a chronic, relapsing brain disease. Sex and ovarian hormones are known to influence cocaine addiction liability and relapse vulnerability. However, little is known regarding the cellular and synaptic mechanisms contributing to sex differences in relapse vulnerability, including how these measures are influenced by hormonal fluctuations. To investigate sex differences in relapse vulnerability we use a rodent model of cocaine craving and relapse called the incubation model in which cue-induced seeking progressively increases or “incubates” during the first month of withdrawal from extended-access cocaine self-administration. Using this model, we have recently shown that females in the estrus …
A Mathematical Model Of Vagus Nerve Stimulation In Alzheimer's Disease, Julianne Miranda
A Mathematical Model Of Vagus Nerve Stimulation In Alzheimer's Disease, Julianne Miranda
Undergraduate Honors Theses
Alzheimer’s Disease is a neurodegenerative condition characterized by cognitive decline as a result of brain atrophy. The exact cause of Alzheimer’s is unknown but current theories involve the aggregation of amyloid beta plaques as well as neurofibrillary tangles. Inflammation is emerging as central to the progression of the disease, with increased amyloid beta plaques and neurofibrillary tangles associated with the Nuclear Factor Kappa B pathway. This project presents a mathematical model of the impact of vagus nerve stimulation in Alzheimer’s Disease, as seen through the Nuclear Factor Kappa B (NFKB) pathway. The model examines several factors involved in the inflammatory …
