Establishing the posh scaffold as a novel therapeutic target for treatment of B cell leukemia
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] More than 60,000 new cases of leukemia will be diagnosed in the U.S. this year. B cells comprise 10 [percent] of acute lymphoblastic leukemias ...
Interplay of Bacillus anthracis spore proteins in the assembly process of the exosporium
(University of Missouri--Columbia, 2023)
Spores are the infectious form of the zoonotic pathogen, Bacillus anthracis. The outermost layer of these spores is the exosporium. It consists of a basal layer (major structural proteins are ExsY, CotY, BxpB, and ExsFB) ...
A role played by sex in innate immune memory and disease severity
(University of Missouri--Columbia, 2023)
While immunological memory has traditionally been understood to be solely within the purview of adaptive immunity, recent evidence has shown that a type of "memory" exists in innate immune cells, as a prior insult can lead ...
Virus interactions with the sphingolipid network : sphingosine kinase 2 in immunosuppression, immunopathology, and viral propagation
(University of Missouri--Columbia, 2020)
Sphingosine 1-phosphate (S1P) is a bioactive lipid molecule known to regulate diverse cellular functions. S1P is metabolized by the sphingosine kinases (SphK) and S1P lyase (SPL). However, little is known about the role ...
Understanding the role of Coxiella outer membrane protein-1 in relation to the Type IVB Secretion system of Coxiella burnetii
(University of Missouri--Columbia, 2022)
Obligate intracellular bacterial pathogens, like Coxiella burnetii, the causative agent of Q Fever, rely upon the host for metabolites and carbon sources for energy and biosynthesis of nucleic acids, proteins, and energy ...
Understanding the insect immune responses to Yersinia pestis using Drosophila melanogaster
(University of Missouri--Columbia, 2022)
Yersinia pestis, the causative agent of plague, continues to be transmitted in many different continents, most often by fleas. Despite knowing for a century that Y. pestis can form a biofilm on the flea's proventriculus ...
Evaluation of calcium handling and dwarf open reading frame AAV gene therapy in Duchenne muscular dystrophy
(University of Missouri--Columbia, 2022)
Duchenne muscular dystrophy (DMD) is a progressive muscle wasting disease. Increased concentrations of cytosolic calcium in dystrophic muscle cells has been implicated in DMD pathogenesis. In healthy muscle, calcium from ...
Investigating the deleterious role of B lymphocytes during brucella infection
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Brucellosis is a disease known for inducing chronic, often life-long, infections. While it is clear the host immune response fails to clear ...
The influence of type II cytokines in central tolerance
(University of Missouri--Columbia, 2021)
While the genetic elements of many autoimmune conditions have been established, many environmental factors remain a mystery. Exposure to certain infections has been implicated as a possible explanation for the significantly ...
Interactions between helicobacter-induced inflammation acute changes in the gut microbiota, and colorectal cancer in Smad3-/- mice
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Colorectal cancer (CRC) is the second leading cause of cancer-related mortality worldwide, accounting for 551,269 deaths in 2018 alone. One ...
Maintenance of relational bindings: working memory or long-term memory?
(University of Missouri--Columbia, 2022)
While there has been a wealth of research examining the effects of feature binding in working memory (WM), it remains unclear how relational bindings (pairings of items, or of an item to its presented serial position) are ...
Influenza virus strategies to regulate S1P-metabolizing enzymes and evade host innate immunity for robust viral replication
(University of Missouri--Columbia, 2021)
Viral infection is a complex network of interactions involving the host defending itself against the virus and the virus attempting to subdue host defenses and utilize the cellular machinery to promote its replication. ...
Inhibition and comprehensive analysis of hiv-1 vpu, examination of retroviral trafficking, and characterization of sars-cov-2 genetic material in wastewater
(University of Missouri--Columbia, 2021)
Both HIV-1 and SARS-CoV-2 have been responsible for millions of infectionrelated deaths. Despite advances in treatment for both viruses, neither has a cure, and those living with the disease can unknowingly spread the ...
Refinement of an established large-animal model to understand the tick-pathogen-host interface
(University of Missouri--Columbia, 2021)
Ticks are globally distributed vectors of important pathogens of human and animal health. Since the discovery of tick resistance in 1918, the field has sought continuously for the development of effective biologic control ...
Chimeric Thrombomodulin and CD47 proteins synergistically improve the engraftment of islets by mitigating IBMIR
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 5/1/2024] The main aim of this dissertation was to display novel immunological ligands, Thrombomodulin (TM) and CD47, on the surface of islets to promote islet engraftment by controlling thrombotic/inflammatory ...
Yersinia pestis YopJ and its impact on innate immunity
(University of Missouri--Columbia, 2022)
Yersinia pestis is one of the most virulent pathogens known to man, with the most impactful epidemics in human history. As the causative agent for the plague, Y. pestis has demonstrated its propensity to ravage through ...
Comparative study of Human Immunodeficiency Virus type 1 and type 2 single and dual infections
(University of Missouri--Columbia, 2020)
Human Immunodeficiency Virus (HIV) type 1 and type 2 are two related lentiviruses that have strikingly divergent features in terms of transmission rates, distribution, pathogenesis, and clinical outcomes. In places where ...
