Atm-/-Ung-/- Mice Present Reduced Levels Of Switched Immunoglobulin Isotypes Igg1 And Igg3, Lyric M. Haughton

Dissertations and Theses

B cells excise and recombine the immunoglobulin heavy chain gene locus during class switch recombination (CSR). CSR is mediated by activation induced cytidine deaminase (AID) and results in a new immunoglobulin isotype that B cells will secrete and present. AID produces mutations that convert cytosines to uracils within the intronic switch regions that precede and follow the target immunoglobulin isotype coding sequence. To resolve the mutations, B cells conduct either base excision repair (BER) or mismatch repair (MMR). Inactivating genetic mutations in BER or MMR reduce CSR. For example, a knock-out of uracil DNA glycosylase (UNG) causes a 50% reduction …

Translocations Of North American Bison Across Large Climatic Gradients: Impacts On Thermoregulation, Body Size, And Helmintic Infection, Hayden Wolfe

Electronic Theses and Dissertations

Every year, one-eighth of all North American bison (Bison bison) are translocated, often across large climatic gradients. Over the last 16 years bison have been translocated from Wind Cave National Park in South Dakota to establish six herds across the United States central grasslands in Iowa, Missouri, Illinois, Indiana, and Kansas. Influence of climatic gradients on herd-level thermoregulation, body size, and helmintic infection were evaluated. Overall, 1174 thermal images and 1050 fecal samples were collected between 2021 and 2023. Physiological heat flux was used to measure thermoregulation, asymptotic body mass (ABM) was used for body size, and helminth genera abundance …

Extracellular Free Water As An Imaging Biomarker Of Neuroinflammation, Cristina N. Pinheiro

Theses and Dissertations--Psychology

Older adults experience a chronic state of heightened immune response referred to as “inflammaging” which can be observed by detecting levels of proinflammatory cytokines in blood serum. These proinflammatory cytokines are secreted in the central nervous system and may also enter the brain through the blood brain barrier. Previous literature has suggested that extracellular free water, a magnetic resonance imaging metric, may allow us to detect alterations in the extracellular space which are thought to correlate with inflammation in the central nervous system. This study examined the correlation between two proinflammatory cytokines, IL-6 and TNFα, collected longitudinally and cross-sectionally imaged …

Crigna, Cristina Daniele, Carsten Sticht, Maike Cueppers, Mark A. Kluth, Christoph Ganss, Markus H. Frank, Norbert Gretz, Karen Bieback

Research outputs 2022 to 2026

Acute kidney injury (AKI) is characterized by a rapid reduction in renal function and glomerular filtration rate (GFR). The broadly used anti-cancer chemotherapeutic agent cisplatin often induces AKI as an adverse drug side effect. Therapies targeted at the reversal of AKI and its potential progression to chronic kidney disease or end-stage renal disease are currently insufficiently effective. Mesenchymal stromal cells (MSCs) possess diverse immunomodulatory properties that confer upon them significant therapeutic potential for the treatment of diverse inflammatory disorders. Human dermal MSCs expressing ATP-Binding Cassette member B5 (ABCB5) have shown therapeutic efficacy in clinical trials in chronic skin wounds or …

Elucidating Mechanisms Of Enhanced Dsrna-Nanophytoglycogen Innate Immune Responses In Healthy Human Cells, Nicholas Jadaa

Theses and Dissertations (Comprehensive)

Immunostimulatory nucleic acids, such as long double-stranded RNA (ds)RNA, can stimulate innate immune responses in a non-sequence specific manner. These molecules are recognized by pattern-recognition receptors in the cytoplasm, endosome, and on the cell surface. Activation leads to the production of mediators of innate immune pathways, including type I interferon and proinflammatory cytokines. Although these receptors are present in all cells, their role in non-immune cells is often overlooked due to their lower level of responsiveness. Nanocarriers can enhance these nucleic acid-mediated responses, allowing for exploration of innate immune pathways in non-immune cells. Nanoparticles as carriers of nucleic acids can …

Ribosome Hibernation Factor Induces Antibiotic Persisters Of Mycobacterium Tuberculosis In Neutrophil-Rich Lung Lesions, Jamie Corro

Electronic Theses & Dissertations (2024 - present)

Mycobacterium tuberculosis (Mtb), the etiological agent of tuberculosis, is a prescient global health threat and the leading cause of death by an infectious agent. Treatment of Mtb infection involves administering 2-4 antibiotics for a minimum of 6 months. This extended drug regimen is required to target a subpopulation of persistent bacilli. As their name implies, these bacteria can “persist” by acquiring nonhereditary and transient antibiotic tolerance. Although the precise mechanism is unknown, it’s often attributed to slowing cellular growth and metabolic processes. During zinc deprivation, bacteria can remodel their ribosomes by replacing their zinc-binding paralogues containing the CXXC motif (C+) …

Endovascular Interventions In Cancer Patients With Compromise Of The Mediastinal Vasculature: A Review, Steven Yevich, Nicolas Cardenas, Rahul Sheth, Joshua Kuban, Milan Patel, Ketan Shah, Koustav Pal, Stephen R Chen, Alda Tam

Faculty, Staff and Student Publications

The mediastinal vasculature can be affected by various etiologies in cancer patients. Both direct and indirect sequela of cancer may result in life-threatening clinical presentations. Tumor growth may cause vessel narrowing and decreased blood flow from either extrinsic mass effect, invasion into the vascular wall, or tumor thrombus within the lumen. In addition, cancer patients are predisposed to indirect sequela to the mediastinal vasculature from an increased risk of benign thromboembolic events, tumor thrombus, or iatrogenic complications during cancer treatments. Benign thrombus may result in partial or complete occlusion of the superior vena cava (SVC) or pulmonary artery. Vascular damage …

Faculty, Staff and Student Publications

Achieving and maintaining the therapeutic range in vancomycin treatment is important for optimal outcomes. While guidelines and best practices based on empirical studies exist, the theoretical best dosing strategies under various conditions remain illusive. We developed an RL-based simulation framework using a deep learning two-compartment pharmacokinetic model (PK-RNN-2CM) and introduced the area under the time-concentration curve (AUC) reward score, which translates clinical guidelines into an RL reward. Ground truth time-concentration curves were generated from patient-specific data, and simulated curves were produced under different dosing strategies with optional noise perturbations to mimic real-world settings. Evaluation metrics included 24-hour AUC assessments and …
