Plasmodium malariae and Plasmodium vivax are protozoan parasites that can cause malaria in humans. They are genetically indistinguishable from, respectively, Plasmodium brasilianum and Plasmodium simium, that is, parasites infecting New World non-human primates in South America. In the tropical rainforests of the Brazilian Atlantic coast, it has long been hypothesized that P. brasilianum and P. simium in platyrrhine primates originated from P. malariae and P. vivax in humans. A recent hypothesis proposed the inclusion of Plasmodium falciparum into the transmission dynamics between humans and non-human primates in the Brazilian Atlantic tropical rainforest. Herein, we assess the occurrence of human …

Cancer Salt Nostalgia, Aashish S. Allu, Venkataswarup Tiriveedhi

Biology Faculty Research

High-salt (sodium chloride) diets have been strongly associated with disease states and poor health outcomes. Traditionally, the impact of salt intake is primarily studied in cardiovascular diseases, hypertension and renal diseases; however, recently there has been increasing evidence demonstrating the role of salt in autoimmune diseases. Salt has been shown to modulate the inflammatory activation of immune cells leading to chronic inflammation-related ailments. To date, there is minimal evidence showing a direct correlation of salt with cancer incidence and/or cancer-related adverse clinical outcomes. In this review article, we will discuss the recent understanding of the molecular role of salt, and …

Identifying The Cell Composition And Clonal Diversity Of Supratentorial Ependymoma Using Single Cell Rna-Sequencing, James He

University Scholar Projects

Ependymoma is a primary solid tumor of the central nervous system. Supratentorial ependymoma (ST-EPN), a subtype of ependymomas, is driven by an oncogenic fusion between the ZFTA and RELA genes in 70% of cases. We introduced this fusion into neural progenitor cells of mice embryos via in utero electroporation of a non-viral binary piggyBac transposon system containing ZFTA-RELA. From preliminary data in the LoTurco lab, inducing the expression of ZFTA-RELA into different neural progenitor cells produces tumors of varying lethality and cellular composition. To define the cellular composition and subclonal diversity of ST-EPN tumors, we used single cell RNA-sequencing to …

Stovgaard, Karama Asleh, Nazia Riaz, Samuel Leung, Dongxia Gao, Lise B. Nielsen, Anne-Vibeke Lænkholm, Eva Balslev, Maj-Britt Jensen, Dorte Nielsen, Torsten O. Nielsen

Centre for Regenerative Medicine & Stem Cell Research

Preclinical studies suggest that some effects of conventional chemotherapy, and in particular, gemcitabine, are mediated through enhanced antitumor immune responses. The objective of this study was to use material from a randomized clinical trial to evaluate whether patients with preexisting immune infiltrates responded better to treatment with gemcitabine + docetaxel (GD) compared to docetaxel alone. Formalin fixed, paraffin-embedded breast cancer tissues from SBG0102 phase 3 trial patients randomly assigned to treatment with GD or docetaxel were used. Immunohistochemical staining for CD8, FOXP3, LAG3, PD-1, PD-L1 and CD163 was performed. Tumor infiltrating lymphocytes (TILs) and tumor associated macrophages were evaluated. Prespecified …

Marinopyrrole Derivatives As Putative Antiparasitic Molecules Promoting Initiation Of Programmed Cell Death In Toxoplasma Gondii, Matthew C. Martens

Theses & Dissertations

Toxoplasma gondii is a globally-distributed obligate intracellular parasite and the causative agent of toxoplasmosis in humans, a biphasic disease often culminating in lifelong chronic infection. Though often mild, toxoplasmosis can lead to severe clinical presentation in immunocompromised patients and developing fetuses. Current therapeutic options are severely limited, with a combinatorial pyrimethamine/sulfadiazine regimen acting as the current standard of care for toxoplasmosis; however, both of these compounds can elicit serious adverse reactions in patients, and, additionally, are only effective against the acute stage of infection. To address these limitations, screenings of several analogs derived from the marine natural product marinopyrrole A …

Effects Of A Low Crude Protein Diet With And Without Spirulina Platensis Inclusion On The Concentrations And Proportions Of Circulating Immune Cells In Broilers, Heather Glenn

Poultry Science Undergraduate Honors Theses

Immune system health is an important aspect of broiler production, especially with the reduction of the use of antibiotics. Nutritional aspects, like crude protein percentage, and natural alternatives to antibiotics are being investigated to see the effect they have on immunity. Spirulina is an alternative proteinaceous ingredient that producers are looking into, not only due to its high nutritional value, but also its immune boosting properties. The purpose of this study was to determine the effects of a low crude protein diet (LCP) and a Spirulina-supplemented low crude protein (LCP-SP) diet on broiler blood cell measurements, including, concentrations and proportions …

Temperature-Dependent Macrophage Activity In Rainbow Trout, Danica Mcgrevey

Biological Sciences Undergraduate Honors Theses

Fever is an essential component of the immune response. Fever enhances immune responses as well as creates an environment in which the body has advantages over pathogens. Macrophages are often the first cells that come in contact with pathogens, as they reside in tissues. They are important for their engulfment of pathogens that results in the digestion of the pathogen, but they also produce nitric oxide and cytokines that contribute to immune response in a variety of ways, including initiating adaptive immunity and directing the production and activity of other immune cells. We were curious about macrophages from other temperature …

Sodium Pyruvate Ameliorates Influenza A Virus Infection In Vitro And In Vivo, Jessica M. Reel

Graduate Theses/Dissertations

Pyruvate is produced in duplicate at the end of glycolysis in addition to ATP and NADH. Pyruvate is the metabolite of choice in most cells, whether obtained exogenously or endogenously. Recently we found that the addition of pyruvate’s conjugate base, sodium pyruvate, to cell culture media dampened the immune response to influenza A virus (IAV) infection in cultured innate immune cells. Thus, I decided to investigate the mechanism and potential for treatment of IAV. In vitro using bone marrow derived macrophages that were infected with IAV we found that adding sodium pyruvate to the media decreased immune signaling pathways through …

Assessing The Durability Of The Immune Response Induced By Rivax®, A Ricin Subunit Vaccine, Hayley Lynn Novak

Legacy Theses & Dissertations (2009 - 2024)

Assessing the performance and durability of the antibody response in animal models can assist in the development of biodefense vaccines. Ricin is one of the most toxic biological agents known and has been a public health issue for years. Since ricin is easily manufactured and a deadly toxin, rational vaccine design and immunotherapeutic optimization have been explored. RiVax® is a candidate subunit vaccine with a modified A-chain of ricin toxin that was formulated to remove ricin's biological activity. It is thought that RiVax® could serve as a prophylactic that would induce humoral- and cell-mediated immunological responses that elicit protective antigens …

Component Causes Of Infectious Bovine Keratoconjunctivitis - The Role Of Moraxella Species In The Epidemiology Of Infectious Bovine Keratoconjunctivitis, John Dustin Loy, Matthew Hille, Gabriele Maier, Michael L. Clawson

School of Veterinary and Biomedical Sciences: Faculty Publications

Moraxella bovis can cause infectious bovine keratoconjunctivitis (IBK).

The role of M bovoculi in IBK is not fully understood.

M bovis and M bovoculi appear to undergo genetic recombination with each other or other members of the Moraxellaceae.

Recombination complicates their classification and potential role(s) in IBK pathogenesis.

MALDI-TOF MS is used to identify M bovis, 2 major strains or genotypes of M bovoculi, M ovis, and other members of the Moraxellaceae.

Classification and determination of pathogenesis potential within Moraxella species may be better understood through whole genome sequencing.

Recent Advances In Understanding Tick And Rickettsiae Interactions, Shahid Karim, Deepak Kumar, Khemraj Budachetri

Faculty Publications

Ticks are haematophagous arthropods with unique molecular mechanisms for digesting host blood meal while acting as vectors for various pathogens of public health significance. The tick's pharmacologically active saliva plays a fundamental role in modulating the host's immune system for several days to weeks, depending on the tick species. The vector tick has also developed sophisticated molecular mechanisms to serve as a competent vector for pathogens, including the spotted fever group (SFG) rickettsiae. Evidence is still inadequate concerning tick–rickettsiae–host interactions and saliva-assisted transmission of the pathogen to the mammalian host. Rickettsia parkeri, of the SFG rickettsia, can cause a …

Synthetic Viral Pyrogen Induces Behavioral Fever In Plethodon Glutinosus Salamanders, Nicholas Britt

Undergraduate Honors Theses

Behavioral fever is an essential coping mechanism across ectothermic phyla to aid in combating pathogenic threats. Ectotherms lack internal temperature regulation associated with fever in endotherms; thus, ectotherms can exhibit a behavioral fever response when immunocompromised to thermoregulate by moving to warmer locations. The salamander order Caudata, tend to be keystone species in their resident ecosystems through their role as secondary consumers of invertebrates to maintain the food chain. With growing interest about ecology and conservation of salamanders as species diversity declines, this study was designed to determine if salamanders use their environment to take advantage of behavioral fever. The …

The Role Of Pag1 In The Activated B-Cell Subtype Of Diffuse Large B-Cell Lymphoma, Jared Henderson

Dissertations and Theses (Open Access)

Diffuse Large B Cell Lymphoma (DLBCL) is the most common aggressive hematologic malignancy in adults, but despite recent advances in treatment, many patients today still face poor outcomes. Of the two types of DLBCL, activated B-cell (ABC) and germinal center B-cell (GCB), patients diagnosed with the ABC subtype especially face a lack of effective treatment options. Unlike GCB-DLBCL, ABC-DLBCL is characterized by chronic antigen-driven signaling by the B-cell receptor (BCR), indicating an escape from immunologic tolerance mechanisms that normally regulate self-reactive B cells. While recent therapies have focused on inhibiting the kinases that propagate BCR signaling with mixed success, we …

Harnessing The Power Of Trained Immunity In The Setting Of Pancreatic Cancer: A Novel Mechanism Of Immune Trafficking And Tumor Control., Anne Elena Geller

Electronic Theses and Dissertations

Despite the success of immunotherapy in many types of cancer, pancreatic adenocarcinoma (PDAC) has yet to benefit. Innate immune cells are critical to antitumor immunosurveillance and recent studies have revealed that these populations possess a form of memory, termed trained innate immunity, which occurs through transcriptomic, epigenetic, and metabolic reprograming. Though trained innate immunity has mostly been investigated in the context of infection, the induction of trained innate immunity could also protect against tumors, and specifically pancreatic tumors. Here, we demonstrate that yeast-derived particulate β-glucan, a known inducer of trained immunity, traffics to the pancreas following IP administration. This causes …

Assessing The Outcomes Of Blocking Ccl2-Ccr2 Signaling Axis On Breast Cancer Brain Metastasis, Yutao Qi

Dissertations and Theses (Open Access)

Breast cancer brain metastases have remained one of the most intense challenges for precision cancer therapeutics, but current treatment options are limited and not curative. Recently, our lab reported that adoptive PTEN downregulation in metastatic breast tumor cells activates PI3K/NF-ƙB signaling and increases the secretion of the chemokine CCL2, which enhances the chemotaxis of CCR2⁺ myeloid cells, a major subpopulation of bone marrow-derived myeloid cells (BMDMs), from peripheral blood into the brain tumor microenvironment (TME), eventually promoting brain metastasis outgrowth by driving immune suppression. Here, in this project we have been aiming to develop effective therapies by immune-modulating the …

Unraveling Host-Gut Microbiota Dialogue And Its Impact On Response To Immune Checkpoint Blockade, Alexandria Cogdill

Dissertations and Theses (Open Access)

Cancer is a disease with only one degree of separation, affecting one in two men and one in three women in their lifetimes; accounting for 1 of every 6 deaths. While cancer mortality rates continue to improve, incidence rates are expected to rise and shift through 2050 due to epidemiological and demographic transitions worldwide. As such, it is imperative to continue to investigate and improve our understanding of both disease etiology and hallmarks of response to treatment. Currently, conventional therapies include, but are not limited to, surgery, chemotherapy, and radiotherapy. However, within the past decade, major advances have been made …

Suppression Of Inflammation Of Cytokine Following Induced Francisella Tularensis Infection, Nicole Renee Setzu

Open Access Theses & Dissertations

Francisella tularensis is intracellular bacteria which is the causative agent of the disease Tularemia. Highly virulent in both humans and animals, it takes only as few as 10 microorganisms to cause a lethal infection. The bacteria can enter via direct or indirect routes causing the activations of the host innate inflammatory response to ensue. The bacteria invade host dendritic cells and neutrophils but predominately macrophages. This causes a mass inflammatory response resulting in the cytokine storm. Activation of Natural Killer T (NKT) cells has been shown to suppress inflammation in in vivo studies. Development and optimization of an in vitro …

Data for stories published in the first four days of every month from March through September was compiled for 2019 and 2020. Our findings showed a 78.85% decrease in coverage of environmental issues between 2019 and 2020 when stories related to the coronavirus pandemic …

Association Of Trim Gene Variation And Lpdv Infection Patterns In Wild Turkeys, Bennett Fry

Honors Theses

Emerging infectious diseases pose a serious threat to various species throughout the globe, including humans. The lymphoproliferative disease virus (LPDV) in wild turkeys is an example of disease virus whose impact on its host requires additional study. Although the first description of lymphoproliferative disease came from outbreaks in domestic turkey flocks in Europe, it is now known that LPDV is widespread in wild turkey populations in North America. In an effort to understand what may affect an individual turkey’s susceptibility to this virus, variation in part of the anti-viral TRIM62 gene was investigated. DNA was extracted from hunter-collected, turkey blood …

Medical Populism And Covid-19 Testing, Kristin Hedges, Gideon Lasco

Development Studies Faculty Publications

This paper uses the lens of medical populism to analyze the impact of biocommunicability on COVID-19 testing through a case study approach. The political efficacy of testing is traced through two mini-case studies: the Philippines and the United States. The case studies follow the approach of populism scholars in drawing from various sources that ‘render the populist style visible’ from the tweets and press releases of government officials to media reportage. Using the framework of medical populism, the case studies pay attention to the ways in which coronavirus testing figured in (1) simplification of the pandemic; (2) spectacularization of the …

215— Schistosomiasis Infections In School Aged Children In Ghana, Katerina Pisciotta, Maia Mazzaferro

GREAT Day Posters

Schistosomiasis is a Neglected Tropical Disease caused by a parasitic blood fluke. There are currently over 240 million people affected globally. Humans become infected after coming into contact with water containing the infectious stage of the parasite. Our data consists of egg counts for Schistosoma haematobium and Schistosoma mansoni collected from school-aged children in Tomefa, Ghana, a marginalized informal community, between 2014 and 2019. Our research explores whether or not reinfections and continuous infections were occurring over the six-year period. Although the government conducts periodic mass drug administration, reinfections are likely given the social and environmental conditions in the community. …
