Using Hyperactive Shp-2 Mutants, A Phosphatase, To Identify Interactions With The Rna Helicase Ddx3, Devin Montgomery

Theses and Dissertations--Pharmacy

Protein-protein interactions are critical in cellular signaling pathways. This project investigates binding interactions between SHP-2, a tyrosine phosphatase, and DDX3, an RNA helicase. There is a specific focus on the impact that gain-of-function SHP-2 mutations may impact binding to DDX3 via conformational change. Using immunoprecipitation protocols as well as western blotting we were able to provide insights into SHP-2 molecular mechanisms and subsequent binding to DDX3.

Anxiolytic Intervention: Modulation Of Cell Types Due To Nicotine Withdrawal, Taylor Elder

Theses and Dissertations--Pharmacy

Nicotine use disorder (NUD) remains a leading cause of preventable disease, yet the neurobiological mechanisms underlying nicotine withdrawal are incompletely understood. Emerging evidence implicates neuroimmune signaling and astrocytic regulation of glutamate in shaping the withdrawal-associated affective phenotype. This dissertation investigated these processes using multiple nicotine administration paradigms including osmotic minipump implant, cigarette smoke exposure, and nicotine vapor inhalation to model diverse routes of human nicotine intake.

Chapter 2 examines the effects of these three modes of administration on neuroinflammation and validation of nicotine delivery. Nicotine exposure was confirmed through receptor [³H]Epibatidine nAChR binding assay and serum cotinine measurements. …

Investigating The Role Of Dynamic Signaling Of Nrg3-Erbb4 In The Prefrontal Cortex In Mediating Nicotine Withdrawal Phenotypes, Emily Prantzalos

Theses and Dissertations--Pharmacy

While several pharmacotherapies are currently available for nicotine use disorder (NUD), smoking cessation success rates remain below 10% each year. The molecular mechanisms underlying failed quit attempts continue to represent a critical gap in our knowledge. However, recent advances in understanding the genetic contributions to nicotine dependence offer a promising avenue for developing more effective cessation therapies. Prior research has identified genetic variation in Neuregulin 3 (Nrg3) and its cognate receptor ErbB4 as potential contributors to affective nicotine withdrawal (WD) phenotypes and cessation outcomes. Therefore, this dissertation aims to systematically investigate the region-specific, functional role of the Neuregulin Signaling Pathway …

Leveraging Transcriptomics And Behavior To Investigate Potential Neuronal And Glial Drivers Of Substance Use Disorder Endophenotypes, Jack V. Keady

Theses and Dissertations--Pharmacy

Over 54 million Americans needed substance use treatment in 2023. While there are many facets of substance use disorder, two major issues of interest are the negative reinforcing aspects of substances of abuse, manifesting in part as withdrawal symptomologies, and why a subset of people who use substances of abuse escalate to a use disorder. Nicotine exposure models were used to investigate the mechanisms of withdrawal endophenotypes, as smoking is the leading cause of preventable death in the United States, and a fentanyl self-administration model was used to probe individual differences in escalation phenotypes, as 80% of overdose deaths in …

The Impact Of Maternal Environmental Exposures On The Immune Landscape Of The Maternal-Fetal Interface, Heather E. True

Theses and Dissertations--Pharmacy

Maternal environmental exposures and inflammation are known to impact fetal development in utero as well as increase the risk for chronic diseases later in life. Therefore, it is essential that we understand how the maternal environment alters placental structure and immune function.

Therefore, we isolated fetal (chorionic villous) tissues from the placentas of healthy pregnant participants (control) and those with inflammatory conditions, including SARS-COV-2 infection, pregravid obesity, and opioid use disorder. Isolated placental leukocytes were subjected to a series of assays to uncover the phenotypic, functional, and transcriptional (single-cell RNA-sequencing) landscape of placental immune cells. Additional placental tissues were subjected …

Optimization And Efficacy Of Car T Cells Derived From Newly Generated Anti-Cd22 Monoclonal Antibody For Blood Cancer Treatment, Wipawadee Ruengdej

Chulalongkorn University Theses and Dissertations (Chula ETD)

Chimeric antigen receptor (CAR) T-cell therapy has revolutionized the treatment of B-cell malignancies. Nevertheless, relapse due to loss of CD19 expression remains a major clinical challenge. CD22 serves as an alternative target because of its consistent expression on malignant B cells, even in CD19-negative disease. Optimization of CD22-directed CAR design is therefore critical to enhance antitumor potency and persistence. Two novel anti-CD22 CAR constructs were generated from monoclonal antibody clones 24A7G6 and 29H9C8, each incorporating either a 4-1BB or CD28 costimulatory domain. The resulting CAR T cells were evaluated for proliferation, phenotype, and cytotoxicity against CD22-positive (Raji, Nalm-6) and CD22-negative …

Alpha-Synuclein Interaction With Gedunin, Tony Matundura Nyabayo

Graduate Theses/Dissertations

Parkinson’s disease (PD) and other Proteinopathies develop when α-synuclein misfolds and aggregates into toxic amyloids. While existing treatments for PD are primarily focused on managing its symptoms, a viable solution for slowing down the progress of Parkinson’s disease involves targeting the toxic α-synuclein amyloids. Gedunin, a natural inhibitor of heat shock protein 90, has been extensively used to treat malaria. Also, recent research investigations have shed light on its potential beyond malaria therapy, indicating that Gedunin may offer a possible solution for treating a variety of neurodegenerative diseases. Using plate-based assays, we examined how Gedunin influences α-synuclein fibrillation and its …
