Exploring The Role Of Il-1Β/Il-1r In The Pathogenesis Of K-Ras Mutant Lung Cancer, Avantika Krishna 2024 The University of Texas MD Anderson Cancer Center

Exploring The Role Of Il-1Β/Il-1r In The Pathogenesis Of K-Ras Mutant Lung Cancer, Avantika Krishna

Dissertations & Theses (Open Access)

As the leading cause of cancer-related deaths worldwide, the development of targeted therapeutics to treat lung cancer remains crucial. Non-small cell lung cancer (NSCLC), the most common histological subtype predominantly comprises lung adenocarcinoma with driver mutations in the K-ras oncogene (KM-LUAD). KM-LUAD progression partly occurs through activation of the NF-κB pathway initiating an inflammatory response and creating a pro-tumor microenvironment. Notably, the pro-inflammatory cytokine IL-1β a potent activator and product of the NF-κB pathway is elevated in the lungs and sera of KM-LUAD patients. We have shown that IL-1β blockade promotes an anti-tumor immune phenotype in a mouse model of …

High-risk type human papillomaviruses (HPV) are associated with genital and oral cancers, and the incidence of HPV+ head and neck squamous cell cancers is fast increasing worldwide. Survival rates for patients with locally advanced disease are poor and variable after standard of care (SOC) treatment. Identifying the antitumor host immune mediators important for treatment response and designing strategies to promote them are essential for improving clinical outcome. The natural killer (NK) cells are a critical component for antitumor innate effector immunity. Among the multitude of activation and inhibitory receptors on immune cells, HLA-DR is recognized as an important activation marker …


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 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 …

Pipecolic Acid And Novel Insights Into Cerebral Malaria, Akua E. Mensah

Theses

Cerebral malaria (CM), a severe manifestation of Plasmodium infection, prompts our investigation into the nuanced role of pipecolic acid in its pathophysiology. To unravel the molecular intricacies, we conducted in vitro lysine labeling techniques of mice infected with P. berghei ANKA parasites, and human P. falciparum grown in vitro, aiming to discern the impact of Plasmodium on pipecolic acid production. Previous observations indicated an elevation in pipecolic acid levels correlating with neurological decline in children with CM. In our study, confirming elevated pipecolic acid presence in the plasma and brain tissues of CM patients and the animal model of CM, …

Mast Cells In Mammary Carcinoma, Alexandria M. Ashbaugh

Undergraduate Honors Theses

Breast cancer (BC) is an aggressive disease that takes the lives of thousands of women every year. Although knowledge and treatment of this disease have improved over the years, much is still to be discovered about BC. One area of expertise that we are currently trying to learn more information about is the mast cell (MC) and its role in BC growth and development. The MC is an immune system component discovered in tumors' extracellular matrix (ECM). As a tumor grows within body tissues, the tumor recruits the MC from surrounding connective tissues to the tumor, using signaling cytokines such …


Antimicrobial Activity Of Cat Flea (Ctenocephalides Felis) Gut Proteins On Different Days After Blood Feeding, Dhruva K. Karnik 2024 Georgia Southern University

Antimicrobial Activity Of Cat Flea (Ctenocephalides Felis) Gut Proteins On Different Days After Blood Feeding, Dhruva K. Karnik

Honors College Theses

Cat fleas (Ctenocephalides felis) are a blood-feeding ectoparasitic insect and a common domestic pest found throughout the world. Because of their reliance on host blood, fleas are exposed to blood-borne pathogens; however, the flea gut lumen is a hostile environment for microbial colonization. For example, the gut epithelia differentially express immune genes in response to feeding. In the present study, we measured the antimicrobial activity of gut proteins from cat fleas at different days after feeding (2, 5, 7, and 14). Dissected flea guts were homogenized, passed through a syringe filter, and measured in a protein assay kit. …


Investigating Vital Neutrophil Extracellular Trap Pathogen Response In Neutropenic Individuals, Ryan Illig 2024 University of Southern Maine

Investigating Vital Neutrophil Extracellular Trap Pathogen Response In Neutropenic Individuals, Ryan Illig

Thinking Matters Symposium

Neutrophils, also called polymorphonuclear leukocytes (PMNs), constitute the majority of innate immune cells. These cells possess a complex arsenal of functions that allow them to detect and eliminate a broad spectrum of pathogens. Neutropenia is characterized by decreased levels of neutrophils in the bloodstream, typically falling below the normal range. Moderate to severe neutropenia can increase the risk of pathogenic infections and without treatment can be life-threatening. Although the concentration of neutrophils in neutropenic individuals is decreased, upon activation, neutrophils still release neutrophil extracellular traps (NETs). NETs are pivotal in combating a spectrum of pathogens through their non-selective nature. Overreactive …

Monophosphoryl Lipid A-Based Adjuvant To Promote The Immunogenicity Of Multivalent Meningococcal Polysaccharide Conjugate Vaccines, Kishore Alugupalli 2024 Thomas Jefferson University

Monophosphoryl Lipid A-Based Adjuvant To Promote The Immunogenicity Of Multivalent Meningococcal Polysaccharide Conjugate Vaccines, Kishore Alugupalli

Department of Microbiology and Immunology Faculty Papers

Activation of the adaptive immune system requires the engagement of costimulatory pathways in addition to B and T cell Ag receptor signaling, and adjuvants play a central role in this process. Many Gram-negative bacterial polysaccharide vaccines, including the tetravalent meningococcal conjugate vaccines (MCV4) and typhoid Vi polysaccharide vaccines, do not incorporate adjuvants. The immunogenicity of typhoid vaccines is due to the presence of associated TLR4 ligands in these vaccines. Because the immunogenicity of MCV4 is poor and requires boosters, I hypothesized that TLR4 ligands are absent in MCV4 and that incorporation of a TLR4 ligand-based adjuvant would improve their immunogenicity. …


Role Of Toll-Like Receptor 2 In Macrophage Recognition And Response To Borrelia Burgdorferi, Yukiye A. Koide 2024 University of San Francisco

Role Of Toll-Like Receptor 2 In Macrophage Recognition And Response To Borrelia Burgdorferi, Yukiye A. Koide

Master's Theses

Lyme disease is the most common vector-borne disease in the US and will experience an uptick as the insect host, the ixodid tick, gains habitat with climate change. The causative agent of Lyme disease, Borrelia burgdorferi, is recognized by Toll-like receptor 2 (TLR2), which initiates the innate immune response. Here, I used ELISA and SEAP detection assays to determine that knocking out TLR2 in THP-1 macrophages reduces the amount of NFkB activation, as well as IL-10 and IL-1β secretion. Then, I used fluorescence microscopy and Incucyte assays to quantify the amount of phagocytosis performed by wild-type and knock-out THP-1 cells. …

Pathology, East Africa

Introduction: Following the coronavirus disease 19 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, vaccination became the main strategy against disease severity and even death. Healthcare workers were considered high-risk for infection and, thus, were prioritised for vaccination.

Methods: A follow-up to a SARS-CoV-2 seroprevalence study among clinical and non-clinical HCWs at the Aga Khan University Hospital, Nairobi, we assessed how vaccination influenced SARS-CoV-2 anti-spike IgG antibody responses and kinetics. Blood samples were drawn at two points spanning 6 to 18 months post-vaccination, and SARS-CoV-2 spike antibody levels were determined by enzyme-linked immunosorbent assay.

Results: Almost all participants, …

Vitro Bacteriophage Treatment For A Staphylococcus Aureus And Pseudomonas Aeruginosa Co-Culture, Alexis Perry 2024 Ouachita Baptist University

Vitro Bacteriophage Treatment For A Staphylococcus Aureus And Pseudomonas Aeruginosa Co-Culture, Alexis Perry

Arkansas Women in STEM Conference

Recent studies show that up 27-36% of all infections are polymicrobial, involving more than one bacteria species. In all categories, polymicrobial infections are often more virulent and harmful to the patient. Since different types of bacteria can communicate with each other through quorum-sensing when in the presence of each other, they can display different genomic characteristics. Further research into polymicrobial infections needs to be done because these changing characteristics can prevent treatment from working, such as antibiotics or bacteriophage therapy. This experiment focused on the co-culture between the two bacteria, Pseudomonas aeruginosa and Staphylococcus aureus, which can be found co-existing …
