Evaluating Functional Inhibitors Of Acid Sphingomyelinase As Potential Negative Modulators Of Microvesicle Particle Release In Response To Skin Stressors, Taskin Sabit

Browse all Theses and Dissertations

Many diseases including lupus erythematosus, atopic eczema, and rosacea can be associated with photosensitivity, which is an abnormal response to sunlight. Recent studies by our group have implicated microvesicle particles (MVP) as playing an important role in causing inflammation and systemic immunosuppression. Previous studies show that functional inhibitors of acid sphingomyelinase (FIASMA) can block MVP release in response to ultraviolet B (UVB) radiation or Platelet-activating Factor (PAF) agonist, which are skin stressors. However, more research needs to be conducted to evaluate the role of PAF, UVB and FIASMA in MVP generation and to formulate a therapeutic medication to be potentially …

Background: Physical activity (PA) is essential following an acute cardiac event. Cardiac rehabilitation (CR) is commonly prescribed, and PA after CR is recommended. Because of age-related changes in functional ability and multi-comorbidity, many older cardiac patients struggle to continue performing PA at home after CR. Depressive symptoms and anxiety are prevalent in cardiac patients and associated with poor self-care, including lack of daily PA. Yoga has been demonstrated to improve psychological and physical health outcomes in cardiac patients, but it is unknown whether yoga, modified for older CR patients – Gentle Yoga – is beneficial in managing psycho- logical distress …

Colitis is a chronic bowel disease characterized by damage to the lining of the large intestine, with its precise underlying causes remaining incompletely understood. In this study, we provide evidence that circular RNA circNlgn plays a pivotal role in promoting the development of colitis. Colitis patients produce significant higher levels of circNlgn. Transgenic mice expressing circNlgn exhibit heightened susceptibility to colitis development and progression, primarily attributed to the presence of the protein isoform Nlgn173 encoded by circNlgn. Nlgn173 undergoes translocation into cell nuclei, where it interacts with actin, impeding the binding of actin-related protein 2 and 3 (Arp2/3) complex to …

Exenatide As Chronopharmacotherapy For T2dm Associated Complications: Targeting Nondipping Blood Pressure And Sleep Insufficiency, Aaron Chacon

Theses and Dissertations--Pharmacology and Nutritional Sciences

Although largely impacted by age, race and ethnicity, and socioeconomic factors, Type 2 Diabetes Mellitus (T2DM) is primarily driven by obesity, currently affecting ~30 million in the U.S and ~463 million globally. T2DM carries numerous complications, including high prevalence of hypertension and nondipping blood pressure (BP), sleep insufficiency and fragmentation. Nondipping BP is an inadequate drop in BP (≤ 10%) during sleeping hours compared with waking hours. Lending to this, sleep disturbance acts as both precursor and consequence of metabolic dysregulation, greatly impacting circadian rhythmicity. To model these conditions, we utilized diabetic (db/db) mice. These mice carry a point mutation …

The manufacturing process of regulatory T (Treg) cells for clinical application begins with the positive selection of CD25+ cells using superparamagnetic iron oxide nanoparticle (SPION)-conjugated anti-CD25 antibodies (spCD25) and immunomagnetic cell separation technology. Our findings revealed that the interaction of spCD25 with its cell target induced the internalization of the complex spCD25–interleukin-2 receptor. Accumulation of intracellular spCD25 triggered oxidative stress, causing delayed Treg expansion and temporary reduction in suppressor activity. This activation delay hindered the efficient generation of clinically competent cells. During this early phase, Treg cells exhibited elevated mitochondrial superoxide and lipid peroxidation levels, with a concomitant decrease …


Anatomical And Physiological Characterization Of Striatal Activation Of The Cerebral Cortex, Yuhan Wang Jan 2024

Anatomical And Physiological Characterization Of Striatal Activation Of The Cerebral Cortex, Yuhan Wang

Theses and Dissertations (ETD)

Purpose. The striatum receives excitatory glutamatergic input from nearly all parts of the cerebral cortex, and its output is delivered by direct pathway medium spiny neurons (dMSNs) expressing D1 type dopamine (DA) receptors (D1Rs) and indirect pathway MSNs (iMSNs) expressing D2 DA receptors (D2Rs). Loss of DA results in the imbalance between the activities of dMSNs and iMSNs in Parkinson’s disease (PD), leading to ab-normal interactions between the cerebral cortex and striatum. Thus, understanding the inter-actions between the cortex and striatum is important. The monosynaptic corticostriatal cir-cuit has been extensively studied. In contrast, due to the poly-synaptic nature of the …

Paradoxes Of Cellular Sumoylation Regulation: A Role Of Biomolecular Condensates?, Xiaodong Cheng, Wenli Yang, Wei Lin, Fang Mei

Faculty, Staff and Student Publications

Protein SUMOylation is a major post-translational modification essential for maintaining cellular homeostasis. SUMOylation has long been associated with stress responses as a diverse array of cellular stress signals are known to trigger rapid alternations in global protein SUMOylation. In addition, while there are large families of ubiquitination enzymes, all small ubiquitin-like modifiers (SUMOs) are conjugated by a set of enzymatic machinery comprising one heterodimeric SUMO-activating enzyme, a single SUMO-conjugating enzyme, and a small number of SUMO protein ligases and SUMO-specific proteases. How a few SUMOylation enzymes specifically modify thousands of functional targets in response to diverse cellular stresses remains an …

Catecholamine-stimulated β2-adrenergic receptor (β2AR) signaling via the canonical Gs–adenylyl cyclase–cAMP–PKA pathway regulates numerous physiological functions, including the therapeutic effects of exogenous β-agonists in the treatment of airway disease. β2AR signaling is tightly regulated by GRKs and β-arrestins, which together promote β2AR desensitization and internalization as well as downstream signaling, often antithetical to the canonical pathway. Thus, the ability to bias β2AR signaling toward the Gs pathway while avoiding β-arrestin-mediated effects may provide a strategy to improve the functional consequences of β2AR activation. Since attempts to develop Gs-biased agonists and allosteric modulators for the β2AR have been largely unsuccessful, here we …
