Combination Therapy Of Ido1 Inhibition And Anti-Pd1 Mediates Anti-Tumor Immunity By Promoting Memory Immunity Development And Cytotoxicity Of Γδ T And Nk Cells Via Il-2 Signaling And By Overcoming Pro-Tumor Effects Of Tgf-Β Signaling, Hyuk Jee
Dartmouth College Master’s Theses
Cutaneous melanoma is the most aggressive form of skin cancer even though it takes only about 1% of all skin cancers. Even among all cutaneous melanomas, NRAS-mutant melanoma is more aggressive than any other, and about 10-25% of all cutaneous melanoma cases have mutations in NRAS. NRAS is a member of the RAS family of proto-oncogenic GTPase proteins, and it plays a key role in signal transduction pathways responsible for cellular survival, proliferation, and metabolism. Immunotherapy is the first line of defense against NRAS-mutant melanoma because, despite tremendous efforts made for decades, it has not been successful to develop small …
Immunopathogenesis Of Post-Infectious Hydrocephalus, 2024 University of Connecticut
Immunopathogenesis Of Post-Infectious Hydrocephalus, Sascha Powers Bernier
Honors Scholar Theses
Hydrocephalus is characterized by the abnormal accumulation of cerebrospinal fluid (CSF) within the brain ventricles. In post-infectious hydrocephalus (PIH) cases, the condition presents challenges in understanding the immune response. PIH is a complex condition, often persisting after the initial infection is treated and thus requiring a deeper understanding of the immune mechanisms involved in its development. This thesis will explore the immunopathogenesis of PIH, elucidating the relationship between the immune response and neurological complications that would succeed infection. The immune response of PIH includes a series of events, beginning with the activation of immune cells and finishing with the release …
The Role Of B Cell Activation State And Sex In Aryl Hydrocarbon Receptor Mediated Induction Of Chemokine Receptor 9 And Alpha4beta7 Expression In Vitro, 2024 University of Northern Colorado
The Role Of B Cell Activation State And Sex In Aryl Hydrocarbon Receptor Mediated Induction Of Chemokine Receptor 9 And Alpha4beta7 Expression In Vitro, Logan Bauerle
Master's Theses
Defense of mucosal tissues from microbial infection and allergy is reliant on continual production of antibodies. The aryl hydrocarbon receptor (AhR) is known to regulate B cell development and is associated with suppression of systemic humoral immunity. Recent attention has been paid to the role of the AhR in altering expression of cell adhesion molecules (CAMs). B cells express CAMs and chemokine receptors to migrate around the body for localized secretion of antibodies. AhR agonists promote B cell migration to the small intestine through upregulation of chemokine receptor 9 (CCR9) and integrin α4β7. Both the AhR …
Remodeling Anaplastic Thyroid Cancer's Aggressive Profile And Metabolic Signature By Natural Alkaloid Berberine, 2024 Touro College and University System
Remodeling Anaplastic Thyroid Cancer's Aggressive Profile And Metabolic Signature By Natural Alkaloid Berberine, Tara Elizabeth Jarboe
NYMC Student Theses and Dissertations
Anaplastic thyroid cancer is a rare, fatal cancer with a five-year survival of 4%. Universally diagnosed at stage IV, anaplastic thyroid cancer is characterized by its lack of differentiation, rapid proliferative rate, highly inflammatory tumor microenvironment, and metabolic dysregulation. Refractory to all established therapies, anaplastic thyroid cancer requires a novel therapeutic approach that targets all of these drivers of anaplastic thyroid cancer carcinogenesis. We propose natural alkaloid berberine as a therapeutic with multitarget efficacy to alter mitochondrial metabolism and reprogram anaplastic thyroid cancer’s aggressive phenotype. Our in vitro model uses monocyte cell line U937, anaplastic thyroid cancer cell lines T238 …

BACKGROUND: Acute myeloid leukemia (AML) is associated with a dismal prognosis. Immune checkpoint blockade (ICB) to induce antitumor activity in AML patients has yielded mixed results. Despite the pivotal role of B cells in antitumor immunity, a comprehensive assessment of B lymphocytes within AML's immunological microenvironment along with their interaction with ICB remains rather constrained.
METHODS: We performed an extensive analysis that involved paired single-cell RNA and B-cell receptor (BCR) sequencing on 52 bone marrow aspirate samples. These samples included 6 from healthy bone marrow donors (normal), 24 from newly diagnosed AML patients (NewlyDx), and 22 from 8 relapsed or …
The Critical Role Of Nac1 In Triple-Negative Breast Cancer Stemness And Immunosuppression, 2024 University of Kentucky
The Critical Role Of Nac1 In Triple-Negative Breast Cancer Stemness And Immunosuppression, Chrispus Ngule
Theses and Dissertations--Toxicology and Cancer Biology
Triple-negative breast cancer (TNBC) is a highly heterogeneous and the most lethal breast cancer (BC) subtype. We report here a new role of nucleus accumbens associated protein 1 (NAC1) in maintaining stemness signature and features of TNBC and controlling the status of myeloid-derived suppressor cells, which accounts for its role in tumor progression and metastasis. This report demonstrates increased NAC1 amplification in TNBC metastatic samples compared to nonmetastatic tissues. In vitro, NAC1 depletion in TNBC cells suppressed their proliferation, colony formation, migration, and invasion. In vivo, NAC1 knockdown in TNBC cells reduced tumorigenic ability, diminished tumor growth rate, and abolished …
The Effect Of Db1976 On The Fibrotic Response In Three-Spined Stickleback (Gasterosteus Aculeatus), 2023 University of Connecticut
The Effect Of Db1976 On The Fibrotic Response In Three-Spined Stickleback (Gasterosteus Aculeatus), Saif Quraishi
Honors Scholar Theses
The study of fibrosis in stickleback has been a growing field in which there have been a few studies conducted. This study examines two experiments involving the inhibition of fibrosis in stickleback. The first experiment used fish from the Kenai River Flats (KRF) in Alaska. The second experiment used fish from Roselle Lake in British Columbia, Canada. To determine the impact the drug had on fibrosis, sticklebacks from the KRF population were treated with DB1976 as well as alum, a pro‐inflammatory vaccine adjuvant that causes fibrosis (Kool et. al 2012). When each DB1976 + alum treatment group was compared with …
Cellular Mechanism Of Pentagalloyl Gucose-Mediated Prevention And Reversal Of Abdominal Aortic Aneurysms, 2023 Clemson University
Cellular Mechanism Of Pentagalloyl Gucose-Mediated Prevention And Reversal Of Abdominal Aortic Aneurysms, Greg Halsey
All Dissertations
Abdominal aortic aneurysm (AAA) has been the 15th leading cause of death in persons older than 55 for the past ten years in several Western countries, with rupture resulting in an almost 100% mortality rate. AAA is a focal dilation of the aorta characterized by progressive loss of elastin and vascular smooth muscle cells (SMCs), as well as persistent inflammatory response [1]. The only treatment for AAA is surgery; however, the mortality post-procedure is still 1-4%, with a 15-30% chance of morbidity [2].
Pentagalloyl glucose (PGG) treatment is effective in the reversal of AAA. While its stabilizing interactions with extracellular …

SECLER Data
Large colonies of two vulnerable, sympatric pinniped species, Peruvian fur seals (Arctocephalus australis Peruvian subpopulation; PFS) and South American sea lions (Otaria byronia; SASL), reside and reproduce in Punta San Juan, Peru (PSJ) where they are exposed to stressors such as contaminants and El Niño Southern Oscillation (ENSO) events. The use of cytokines as immune biomarkers can be indicative of an animal’s health and function by allowing for the assessment of an individual's cytokine balance as type I helper T cells (Th1) or type II helper T cells (Th2) dominant. Utilizing archived pinniped plasma samples from 2009-2019 …
Endothelial Interleukin-17 Receptor D (Il17rd) Promotes Western Diet-Induced Aortic Myeloid Cell Infiltration, 2023 University of Maine
Endothelial Interleukin-17 Receptor D (Il17rd) Promotes Western Diet-Induced Aortic Myeloid Cell Infiltration, Shivangi Pande
Electronic Theses and Dissertations
The Interleukin-17 (IL17) family is a group of cytokines implicated in the etiology of several inflammatory diseases. Interleukin-17 receptor D (IL17RD), also known as Sef (similar expression to fibroblast growth factor), belonging to the family of IL17 receptors, has been shown to modulate IL17A-associated inflammatory phenotypes. The objective of this study was to test the hypothesis that IL17RD promotes endothelial cell activation and consequent monocyte adhesion. We utilized primary human aortic endothelial cells and demonstrated that RNAi targeting of IL17RD suppressed transcript levels by 83% compared to non-targeted controls. Further, RNAi knockdown of IL17RD decreased the adhesion of THP-1 cells …
Complement System In Multiple Sclerosis: Its Role In Disease Course And Potential As A Therapeutic Target, 2023 Dartmouth College
Complement System In Multiple Sclerosis: Its Role In Disease Course And Potential As A Therapeutic Target, Michael R. Linzey
Dartmouth College Ph.D Dissertations
Multiple sclerosis (MS) is a clinically heterogeneous neurological condition characterized by neuroinflammation and neurodegeneration. Relapsing-remitting MS, defined by inflammatory attacks, is the most common initial form of MS and there are currently 23 FDA-approved treatments for these patients. These therapies work primarily by reducing inflammation in the CNS; they do not work well in progressive disease. Therefore, an unmet medical need exists for effective therapeutic options to treat progressive MS (PMS).
In MS, intrathecal immunoglobulins synthesis (IIgS) correlates with disease progression. My goals for this dissertation were to establish the pathological role of IIgS and identify new potential therapeutic …
The Role Of Complement In Stroke And Traumatic Brain Injury, 2023 Medical University of South Carolina
The Role Of Complement In Stroke And Traumatic Brain Injury, Christine Couch
MUSC Theses and Dissertations
Brain and neural injury are a non-specific disease category that includes traumatic brain injury (TBI) and stroke. Both TBI and stroke are common, costly, and leading causes of severe disability in adults. Both stroke and TBI are responsible for substantial disability in working age adults, with stroke being the second leading cause of death worldwide [1] and TBI a major cause of disability in people younger than their 40's [2]. The immune response after brain injury is multifactorial and involves both local and systemic events at the cellular and molecular level. The complement system is a component of both the …
Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, 2023 University of Arkansas, Fayetteville
Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark
Poultry Science Undergraduate Honors Theses
The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of the thyroid glands with mononuclear cells resulting in destruction of the thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies have described mononuclear cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various mononuclear cells infiltrating the thyroids has not been well defined. In this project, the mononuclear cell infiltrate was characterized phenotypically and quantitatively in OS chickens over the …
White Blood Cell Make Up In Kellback Snake Offspring Of Varying Maternal Size, 2023 Kennesaw State University
White Blood Cell Make Up In Kellback Snake Offspring Of Varying Maternal Size, Angelica Mccoy
Symposium of Student Scholars
The immune system is composed of various organs, systems, and other components with one of the most important being white blood cells. White blood cells are commonly separated into two scientific varieties, granulocytes and agranulocytes, which can be differentiated by the presence or absence of granules in the cytoplasm once stained on a slide. There are three granulocytes and two agranulocytes, each with a distinct function and shape. The ratio of these may impact the effectiveness of this portion of the immune system, and multiple factors could play a role in this ratio, an example being the size of an …
The Regulation Of Autoimmunity Genes In Pancreatic Β-Cells By Nf-Κb, 2023 Louisiana State University and Agricultural and Mechanical College
The Regulation Of Autoimmunity Genes In Pancreatic Β-Cells By Nf-Κb, Thomas Malone Martin
LSU Doctoral Dissertations
Type 1 diabetes (T1D) is an autoimmune disease where the immune system targets the pancreatic islet beta-cells, which are responsible for insulin production and secretion, leading to a state of insulin insufficiency. Many of the molecular details of disease onset and progression remain poorly understood, including key aspects of cytokine signaling. Therefore, we have examined some of the consequences of inflammatory cytokine signaling as a critical module relevant to T1D. Using interleukin-1 (IL-1) signaling as a well-defined paradigm for inflammation, we investigated key components of this signaling pathway in pancreatic beta-cells. We identified ICAM-1, one of the proteins expressed in …

Undergraduate Distinction Papers
The dynamic function of vitamin D in an array of immunomodulatory and anti-inflammatory mechanisms and its implication in the pathogenesis of autoimmune diseases has been the topic of much recent scholarship. Here I attempt to elucidate the molecular mechanism of vitamin D-mediated inhibition of the differentiation of CD4+ T cells into pro-inflammatory Th17 cells in MRL/lpr lupus prone mice by investigating how miR-125a expression is affected by dietary modulation of cholecalciferol (vitamin D3). MRL/MpJ and MRL/lpr mice were split into three experimental groups and fed specially formulated diets that varied in their concentrations of vitamin D. …

The Role Of Schwann Cells In Nerve Injury: Forskolin-Mediated Camp Activation Upregulates Tnfα Expression Despite Nf-Κb Downregulation In Lps-Treated Schwann Cells, 2023 Misericordia University
The Role Of Schwann Cells In Nerve Injury: Forskolin-Mediated Camp Activation Upregulates Tnfα Expression Despite Nf-Κb Downregulation In Lps-Treated Schwann Cells, Caitlyn E. Henry, Angela L. Asirvatham Ph.D.
Student Research Poster Presentations 2023
Although Schwann cells are known to play a role in axonal regeneration following nerve injury and inflammation, the exact mechanism is unknown. This study explores two potential mechanisms: the NF-κB and cAMP pathways. The NF-κB pathway produces cytokines, such as TNFα, to regulate inflammation, whereas the cAMP pathway is anti-inflammatory and regulates Schwann cell proliferation via AKAP95 and cyclin D3. Although it is well-known that NF-κB and cAMP are involved in inflammation, not much is known regarding the effects of forskolin-mediated cAMP activation on LPS-mediated NF-κB activation in Schwann cells. In this study, RT4-D6P2T immortalized rat Schwann cells were treated …
