Role Of Chronic Stress-Induced Neuroinflammation In Rodent Locus Coeruleus Physiology And Anxiety-Like Behaviors, Arthur Anthony Alfonso Reyes
Role Of Chronic Stress-Induced Neuroinflammation In Rodent Locus Coeruleus Physiology And Anxiety-Like Behaviors, Arthur Anthony Alfonso Reyes
Graduate School of Biomedical Sciences Theses and Dissertations
The locus coeruleus (LC), the primary site of brain norepinephrine (NE), is a key anatomical brain region implicated in the stress response. Stress is a neuroendocrine physiologic response to a stressor that promotes organism survival through adaptive change and restoration of homeostasis. The central stress response, which drives behavioral and physiological change, is primarily mediated by activating the hypothalamic-pituitary-adrenal (HPA) axis. While advantageous in the short term, chronic stress exposure can lead to HPA axis and LC dysregulation, which are thought to contribute to the etiology of anxiety disorders. Previous studies demonstrate the effects of acute stress in increasing LC …
Immunomodulatory Roles Of The Lysosomal Sialidase Neuraminidase 1, Leigh Ellen Fremuth
Immunomodulatory Roles Of The Lysosomal Sialidase Neuraminidase 1, Leigh Ellen Fremuth
Theses and Dissertations (ETD)
Background Sialic acids are key sugar moieties located at the non-reducing terminals of glycan chains on glycoproteins and glycolipids. By virtue of their location, they influence the functions and biochemical properties of the macromolecules they are bound to. Removal of sialic acids in mammalian cells is carried out by four sialidases, which are differentially expressed and localized in distinct subcellular compartments. Neuraminidase 1 (NEU1), the most abundant and ubiquitous of the four sialidases, functions primarily in the acidic environment of the lysosomes, but can hydrolyze substrates at the plasma membrane, at least in certain cell types. The enzyme initiates the …
Characterization Of Abin-1 In The Traumatically Injured Brain, Aaron Orellana, Alana C. Conti
Characterization Of Abin-1 In The Traumatically Injured Brain, Aaron Orellana, Alana C. Conti
Medical Student Research Symposium
Traumatic brain injury (TBI) is associated with chronic pain and persistent neuroinflammation. Opioids are often prescribed in order to relieve pain symptoms, but recent evidence suggests that their use negatively impacts the neuropathology of TBI leading to behavioral impairments and exacerbated neuroinflammation. The de-ubiquinating enzyme tumor necrosis factor alpha-induced protein (TNFAIP)3 or A20, inhibits the inflammatory signaling transcription factor nuclear factor (NF)-kB leading to attenuation of the inflammatory response. A20-binding inhibitor of nuclear factor kB (ABIN-1), which physically interacts with A20, also plays a role in the inhibition of NF-kB and is poorly researched in the central nervous system (CNS). …
