Harnessing Autoimmunity With Dominant Self-Peptide: Modulating The Sustainability Of Tissue-Preferential Antigen-Specific Tregs By Governing The Binding Stability Via Peptide Flanking Residues, Youwei Lin, Shun Sakuraba, Chandirasegaran Massilamany, Jayagopala Reddy, Yoshimasa Tanaka, Sachiko Miyake, Takashi Yamamura

School of Veterinary and Biomedical Sciences: Faculty Publications

Sensitization to self-peptides induces various immunological responses, from autoimmunity to tumor immunity, depending on the peptide sequence; however, the underlying mechanisms remain unclear, and thus, curative therapeutic options considering immunity balance are limited. Herein, two overlapping dominant peptides of myelin proteolipid protein, PLP136-150 and PLP139-151, which induce different forms of experimental autoimmune encephalomyelitis (EAE), monophasic and relapsing EAE, respectively, were investigated. Mice with monophasic EAE exhibited highly resistant to EAE re-induction with any encephalitogenic peptides, whereas mice with relapsing EAE were susceptible, and progressed, to EAE re-induction. This resistance to relapse and reinduction in monophasic EAE mice was associated with …

Role Of Short Interspersed Nuclear Elements (Sines) Of Maternally Imprinted Microrna Clusters In Hemochorial Placental Antiviral Immunity, Ishani Wickramage

USF Tampa Graduate Theses and Dissertations

The evolution of hemochorial placentas in which the fetal trophoblast is bathed in maternal blood has vastly improved fetal development and survival in primates and rodents, due to the enhanced efficiency of nutrient, gas and waste exchange between the mother and the fetus. However, the extensive contact between the fetal tissues and maternal blood in these placentas also poses an increased risk of vertical transmission of pathogens such as viruses from the mother to the fetus. In response to this selection pressure, hemochorial placentas have evolved robust defense mechanisms to protect the immunologically naive fetus. Unlike somatic cells that require …

The Knowns And Unknowns Of Cardiac Autoimmunity In Viral Myocarditis, Kiruthiga Mone, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

Myocarditis can result from various infectious and non‐infectious causes that can lead to dilated cardiomyopathy (DCM) and heart failure. Among the infectious causes, viruses are commonly suspected. But the challenge is our inability to demonstrate infectious viral particles during clinical presentations, partly because by that point, the viruses would have damaged the tissues and be cleared by the immune system. Therefore, viral signatures such as viral nucleic acids and virus-reactive antibodies may be the only readouts pointing to viruses as potential primary triggers of DCM. Thus, it becomes hard to explain persistent inflammatory infiltrates that might occur in individuals affected …

Faculty, Staff and Student Publications

BACKGROUND: Human papillomavirus (HPV) types 16/18 drive oncogenesis for most patients with cervical, anal, and penile cancers. MEDI0457, a therapeutic DNA vaccine containing plasmids for E6 and E7 HPV-16/18 viral oncogenes and IL-12 adjuvant, is safe and provokes an immune response against E6/E7. We tested MEDI0457 with the anti-PD-L1 antibody durvalumab for patients with HPV-associated cancers.

METHODS: Patients with recurrent/metastatic, treatment-refractory HPV-16/18 cervical cancer, or rare HPV-associated (anal and penile) cancers were eligible. Prior immune checkpoint inhibition was not permitted. Patients received MEDI0457 7 mg intramuscularly (weeks 1, 3, 7, 12, and every 8 weeks thereafter) and durvalumab 1500 mg …

The Eurasian strain of highly pathogenic avian influenza (HPAI) H5N1 is a devastating pathogen for birds that also has the capacity to infect mammals. This report describes the presentation, clinical case findings (including haemogram and serum biochemistry), gross and microscopic lesions and virus detection in three HPAI H5N1-infected domestic cats from the USA in 2023. All three cats presented with neurological abnormalities and were euthanized due to a poor prognosis within 2 days (two cats) or 10 days (one cat) of known clinical disease onset. Necropsy consistently revealed pulmonary congestion and oedema, and cerebrocortical malacia with haemorrhage was also seen …

Sheep Worms – Sustainable Summer-Autumn Worm Control, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

A summer drenching program for sheep worm control is now recognised as a key cause of drench resistance in Western Australia. However, some small changes can increase the sustainability of pre-emptive control programs. Drenches in summer should always be given to younger, growing sheep (current and previous year’s age groups), whereas adult sheep should be drenched in autumn, or if drenched in summer, some should be left untreated (if drenching at all). Research shows that this reduces the chance of developing drench resistance but still provides effective worm control.

Exploring The Interactions Between Sars-Cov-2 And Host Proteins, Sojan Shrestha

School of Biological Sciences: Dissertations, Theses, and Student Research

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the current pandemic, Coronavirus Disease 2019 (COVID-19). SARS-CoV-2 is considered to be of zoonotic origin; it originated in non-human animals and was transmitted to humans. Since the early stage of the pandemic, however, the evidence of transmissions from humans to animals (reverse zoonoses) has been found in multiple animal species including mink, white-tailed deer, and pet and zoo animals. Furthermore, secondary zoonotic events of SARS-CoV-2, transmissions from animals to humans, have been also reported. It is suggested that non-human hosts can act as SARS-CoV-2 reservoirs where accumulated …

Clonal hematopoiesis of indeterminate potential (CHIP) is a premalignant expansion of mutated hematopoietic stem cells. As CHIP-associated mutations are known to alter the development and function of myeloid cells, we hypothesized that CHIP may also be associated with the risk of Alzheimer's disease (AD), a disease in which brain-resident myeloid cells are thought to have a major role. To perform association tests between CHIP and AD dementia, we analyzed blood DNA sequencing data from 1,362 individuals with AD and 4,368 individuals without AD. Individuals with CHIP had a lower risk of AD dementia (meta-analysis odds ratio (OR) = 0.64, P …

RESULTS: 192 patients were enrolled, 66 during escalation and 126 (42 CRC, 42 PDAC, 42 NSCLC) during expansion. No dose-limiting toxicities occurred during escalation. In the monotherapy …

Withaferin A And Immune Checkpoint Blocker Therapy For The Treatment Of Non-Small Cell Lung Cancer, Roukiah Khalil

USF Tampa Graduate Theses and Dissertations

Lung cancer is the first cause of cancer-related deaths in both men and women with an overall five-year survival rate of 28%. Although immune checkpoint blockers (ICBs) are currently FDA-approved for the treatment of non-small cell lung cancer (NSCLC), only 17-20% of patients achieve durable responses by the induction of immunologic memory. The lack of response in most patients can be attributed to the tumor-intrinsic or tumor-extrinsic immune resistance mechanisms. A biomarker of importance is the Programmed Death Ligand-1 (PD-L1), as higher PD-L1 expression is usually associated with a better response to ICBs. Although studies have attempted to combine ICBs …

Acetate-Encapsulated Linolenic Acid Liposomes Reduce Sars-Cov-2 And Rsv Infection, Andrew R. Mcgill

USF Tampa Graduate Theses and Dissertations

Coronavirus disease-19 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), is an ongoing pandemic-endemic. In the United States, it remains the third leading cause of death in 2022. SARS-CoV-2, an RNA virus, has a genome prone to rapid mutation, generating variant species capable of resisting therapies and vaccination efforts. However, it has been estimated that more than 40% of SARS-CoV-2 infections may be asymptomatic, which calls into question any biological differences between the asymptomatic and afflicted groups. Additionally, Respiratory Syncytial Virus (RSV) is the most significant cause of bronchiolitis and asthma in neonates, with an increasing burden on the …

Quantitative Risk Assessment Of Oocyst Versus Bradyzoite Foodborne Transmission Of Toxoplasma Gondii In Brazil, Sophie Zhu, Elizabeth Vanwormer, Beatriz Martínez-López, Lílian Maria Garcia Bahia-Oliveira, Renato Augusto Damatta, Pedro Souto Rodrigues, Karen Shapiro

School of Veterinary and Biomedical Sciences: Faculty Publications

Toxoplasma gondii is a globally distributed zoonotic protozoan parasite. Infection with T. gondii can cause congenital toxoplasmosis in developing fetuses and acute outbreaks in the general population, and the disease burden is especially high in South America. Prior studies found that the environmental stage of T. gondii, oocysts, is an important source of infection in Brazil; however, no studies have quantified this risk relative to other parasite stages. We developed a Bayesian quantitative risk assessment (QRA) to estimate the relative attribution of the two primary parasite stages (bradyzoite and oocyst) that can be transmitted in foods to people in …

Evaluation Of The Humoral Immune Responses To Plasmodium Vivax Circumsporozoite Protein (Csp)-Based Pre-Erythrocytic Vaccine Candidates, Jack Esquenazi

USF Tampa Graduate Theses and Dissertations

Malaria, caused by the apicomplexan Plasmodium spp. , is a major public health issue that impacts over one-third of the world’s population ,with Plasmodium vivax accounting for over 130 million clinical cases annually. The circumsporozoite protein (CSP) is the most abundant molecule on the surface of Plasmodium sporozoites and is considered a leading pre-erythrocytic stage vaccine candidate. CSP is essential for sporozoite maturation, migration, and invasion. Anti-CSP antibodies interrupt sporozoite migration and infection of hepatocytes thus reducing liver-stage burden. P. vivax CSP is composed of three subdomains: a highly polymorphic immunodominant central repeat region (CRR), conserved N-terminal ,and C-terminal subdomains. …

Primary liver cancer is a rising cause of cancer deaths in the US. Although immunotherapy with immune checkpoint inhibitors induces a potent response in a subset of patients, response rates vary among individuals. Predicting which patients will respond to immune checkpoint inhibitors is of great interest in the field. In a retrospective arm of the National Cancer Institute Cancers of the Liver: Accelerating Research of Immunotherapy by a Transdisciplinary Network (NCI-CLARITY) study, we use archived formalin-fixed, paraffin-embedded samples to profile the transcriptome and genomic alterations among 86 hepatocellular carcinoma and cholangiocarcinoma patients prior to and following immune checkpoint inhibitor treatment. …

Preliminary Characterization And Functional Validation Of Pre-Erythrocytic Vaccine Candidates For The Malaria Parasite Plasmodium Vivax, Justin Lee Nicholas Iii

USF Tampa Graduate Theses and Dissertations

RTS,S/AS01, vaccine targeting malaria caused by Plasmodium falciparum, used in moderate to high malaria transmission, provides hope for pre-erythrocytic (PE) subunit malaria vaccine development. Despite this vaccine advance, efforts to develop an efficacious vaccine against the neglected parasite Plasmodium vivax have lagged. In addition, there exists a gap in our understanding of PE antigens that can induce broadly-neutralizing antibodies. In this dissertation, we provide the preliminary characterization of vaccine candidates targeting the PE of P. vivax. Through transcriptomic profiling data and a target product profile, we identified critical P. vivax antigens (SSP3, SPECT-1, and M2-MAEBL) that can potentially be targets …

Stranger Iggs: Beneficial And Detrimental Sides Of Immunoglobulin G Subclasses, Sweta Shrestha

Dartmouth College Ph.D Dissertations

Understanding antibody responses across various immunological conditions can provide valuable insights for the advancement of therapeutic as well as prophylactic interventions. IgG subclass responses, in particular, have garnered the most attention because of their potential role in disease outcomes and treatment efficacy. The four IgG subclasses differ in their hinge region and “constant region” and these differences in turn modulate their antibody functions. Some subclasses demonstrate robust antibody effector functions, while others exhibit diminished effector functions. The consequences of these differences can either be advantageous or disadvantageous, contingent upon the specific context in which they occur.

This thesis explores the …

Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of Johne’s disease, a severe gastroenteritis of ruminants. This study developed a model cell culture system to rapidly screen MAP mutants with vaccine potential for apoptosis. Two wild-type strains, a transposon mutant, and two deletion mutant MAP strains (MOI of 10 with 1.2 × 10⁶ CFU) were tested in murine RAW 264.7 macrophages to determine if they induce apoptosis and/or necrosis. Both deletion mutants were previously shown to be attenuated and immunogenic in primary bovine macrophages. All strains had similar growth rates, but cell morphology indicated that both deletion mutants …

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 …

Newer Surveillance Data Extends Our Understanding Of The Niche Of Rickettsia Montanensis (Rickettsiales: Rickettsiaceae) Infection Of The American Dog Tick (Acari: Ixodidae) In The United States, Catherine A. Lippi, Holly D. Gaff, Robyn M. Nadolny, Sadie J. Ryan

Biological Sciences Faculty Publications

Background: Understanding the geographic distribution of Rickettsia montanensis infections in Dermacentor variabilis is important for tick-borne disease management in the United States, as both a tick-borne agent of interest and a potential confounder in surveillance of other rickettsial diseases. Two previous studies modeled niche suitability for D. variabilis with and without R. montanensis, from 2002-2012, indicating that the D. variabilis niche overestimates the infected niche. This study updates these, adding data since 2012.

Methods: Newer surveillance and testing data were used to update Species Distribution Models (SDMs) of D. variabilis, and R. montanensis infected D. variabilis, in …

METHODS: To develop a DDR1-targeting mAb as a potential cancer therapeutic, we humanized mAb9 with a complementarity-determining region grafting strategy. The humanized antibody named PRTH-101 is currently being tested in a Phase 1 clinical trial. We determined the binding …

Development Of Wiskott-Aldrich Syndrome Knock Out Protocol For Drug Substance Assay Development, Julia C. Hanna

Master's Theses

Wiskott-Aldrich Syndrome (WAS) is a rare X-linked primary immunodeficiency affecting approximately 1 in 100,000 live XY births in North America and is caused by a mutation to the WAS gene which is expressed across hematopoietic lineages. The WAS protein (WASp) plays a role in regulating actin polymerization. On a cellular level, there are a variety of effects of a lack of WASp or expression of a dysfunctional WASp protein for patients including issues with migration, adhesion, chemotactic response, phagocytosis, activation, and proliferation across different cell types in addition to reduced platelet size and output. This can lead to several systematic …
