Pi3kδ Inhibition Alters Cd8 T Cell Differentiation And Reprograms The Tumor Microenvironment Following Adoptive Immunotherapy, Alexandrea Joy Turnquist

Dartmouth College Ph.D Dissertations

T cell exhaustion remains a significant barrier to effective adoptive cell therapy in solid tumors. Here, we demonstrate that in vitro treatment with the PI3Kδ inhibitor CAL-101 generates T cells with enhanced stemness and metabolic fitness, though the stemness of these cells is not dependent on HIF-1α -dependent mechanisms. These cells show increased mitochondrial dependence and spare respiratory capacity while maintaining normal basal metabolism. Under chronic antigen stimulation, CAL-101-treated T cells, including human T cells, resist terminal exhaustion and maintain stem-like properties. Using single-cell RNA sequencing and spatial transcriptomics of B16 melanoma tumors, we found that CAL-101-treated T cells preferentially …

Indian Journal of Research in Homoeopathy

Background: Malnutrition and infectious diseases compromise immune responses, increasing vulnerability to infections. The introduction of plant-derived immunomodulators, such as Bryonia alba (Bry. alba), is attracting attention due to their lower side effects compared with chemical drugs. In Homoeopathy, Bry. alba has long been utilised to treat a wide range of illnesses, including viral infections, and is recognised for its immunomodulatory properties. Objectives: To evaluate the immunomodulatory effects of Bry. alba 6C and 30C potencies on humoral and delayed-type hypersensitivity (DTH) in sheep red blood cell (SRBC)-immunised BALB/c mice. Materials and methods: Fifty BALB/c mice were divided into five …

Historical Chaos Among Tetrabothriideans (Eucestoda) Of Odontocetes (Artiodactyla)—Revising Generic Taxonomy And Species Diversity For Cestodes Among Oceanic Dolphins, Eric P. Hoberg, Kaylen Marie Soudachanh, Robert L. Rausch

MANTER: Journal of Parasite Biodiversity

Explorations over the past 150 years that have defined the diversity and structure of the tetrabothriidean cestode fauna among Odontocete cetaceans (Artiodactyla) are summarized and reviewed. Persistent errors in interpretation of comparative morphological characters, inconsistent taxonomic decisions, and an understanding of generic-level and species diversity are addressed. We outline a revision of the Tetrabothriidea, which now encompasses 8 genera. Prosthecocotyle is resurrected from synonymy with Tetrabothrius, and Cetaceobothridius n. gen is proposed. A clear basis is outlined for differentiation of generic and species diversity among Cetaceobothridius, Priapocephalus, Prosthecocotyle, Strobilocephalus, Tetrabothrius, and Trigonocotyle that constitute the tetrabothriidean fauna of odontocetes; species …

Exploring Foundations Of Animal Host-Microbe Interactions In A Freshwater Sponge, Jacob S. Pawley

Electronic Theses and Dissertations

The most ancient eukaryotic immune defense mechanisms evolved in unicellular species. Multicellular eukaryotes, however, expanded these mechanisms to meet challenges unique to multicellular life, including barrier formation, long-distance cell signaling, and coordinated responses that eliminate microbial threats while minimizing damage to the host. As such, animal immune signaling pathways are exceptionally intricate and diverse. Though, most of what is understood about animal host–microbe interactions stems from a small handful of model systems. Here, I evaluate host–microbe interactions and innate immunity in sponges using the highly tractable freshwater sponge, Ephydatia muelleri. I report the discovery of an external host-derived matrix …

Identification And Characterization Of Novel Immune Modulating Genes In Parkinson's Disease, Kathleen Chaundy Paul Murphy

Dartmouth College Ph.D Dissertations

Parkinson’s disease (PD) is a progressive age-related neurodegenerative disorder characterized by both motor and non-motor symptoms. The poorly understood prodromal period, decades-long progression, and disease-phenotype heterogeneity continue to impede the development of preventive and curative therapies. A growing appreciation of immune system changes during the progression of PD suggests that evaluating peripheral immune cells may help identify signatures relevant to disease etiology. We aimed to expand our understanding of the peripheral immune compartment in PD via two lines of investigation: (1) by employing single-cell RNA sequencing to profile the transcriptomes of peripheral blood mononuclear cells (PBMCs) from a cohort of …

Observing Antibiotic Resistance In Bacterial Co-Cultures Under Simulated Microgravity, Tyler Jenkins, Marina Vaden

Discovery Day - Daytona Beach

Bacteria grow in complex natural environments with multiple factors affecting their growth, metabolism, and physiology. While astronauts are still preparing to travel to Mars, scientists must learn how to simulate a more realistic Martian environment. While a small volume of publications investigates the independent effects of microgravity or Martian regolith on microorganisms (Liao et al., 2025; Allen et al., 2022; Naz et al., 2023; Duri et al., 2025), to our knowledge no current experiments exist on the joint effects of microgravity and Martian simulant on a co-culture. This experiment aims to investigate the effect of a microgravity analog on the …

Metabolic Regulation And Immunity In The Spaceflight Environment, Graeme Grainger, Riley Dienna, Astrid Senko, Angela Cebula, Arden Rodriguez Arden Rodriguez

Discovery Day - Daytona Beach

Long-duration spaceflight exposes astronauts to chronic ionizing radiation and microgravity that disrupts homeostasis in the immune system and cellular metabolism. While simulated spaceflight models demonstrate altered T-cell polarization and sex-dependent shifts toward regulatory phenotypes, the metabolic mechanisms driving these immune changes remain unclear. Immune cell function is tightly linked to metabolic programming, with effector T cells relying on glycolysis and regulatory T cells favoring oxidative metabolism, making them highly sensitive to shifts in nutrient availability and redox balance. Emerging research further suggests that neutrophils act as metabolic regulators capable of reshaping the immune microenvironment through oxidative stress, cytokine production, and …

Impact Of Inspiratory Muscle Training On Diaphragm Hypertrophy, Exercise Performance, And Immune Response, Riley Dienna, Sabrina Ehrenfort, Joshua Frankenfield, Olivia Hartmann, Ben Kerns, Gianpiero Lara, Meliah Martin, Emma Norris, Louis Pandolfo, Rachel Phillips, Stella Roane, Dominic Sandell, Sabrina I. Santini-Bousson, Madison Stroud, Cecilia Zoutewelle, Erica Bryant

Discovery Day - Daytona Beach

The muscles involved in breathing, notably the diaphragm and intercostal muscles, play a role in determining the exercise capability of an individual. These muscles perform the work required for breathing, and as exercise intensity increases these muscles increase their activity to allow the respiratory system to meet the increased metabolic demands of exercise. Fatigue of these muscles reduces exercise tolerance and performance. In addition, the inflammation caused by acute maximal exercise is impacted by the level of training of the individual, and thus, inspiratory muscle training (IMT) may impact the inflammation due to exercise. We will test the hypothesis that …

Gene Therapy Strategies To Enhance Antifungal Immunity In Microgravity, Riley Dienna

Discovery Day - Daytona Beach

During spaceflight, the immune system of astronauts becomes impaired due to microgravity, resulting in increased susceptibility to infections caused by pathogens such as Candida albicans. One of the most common clinical treatments for aggressive candidiasis is amphotericin B, a polyene antimycotic that targeted ergosterol in the fungal cell membrane and compromised the stability of the membrane. However, due to the chemical similarities between ergosterol and cholesterol, this treatment also affects the somatic cells of patients it is administered to. A novel treatment is therefore required to combat the aggressive fungal infection while minimizing damage to the host’s cells. This project …

Nuclear Activities And Interactome Of The Ns5 Protein Of Tick-Borne Encephalitis Virus, Maxime Chazal, Aïssatou Aïcha Sow, Elodie Le Seac'h, Dana Hawasheen, Margarida Bonifacio, Mikael Feracci, Ségolène Gracias, Adrià Sogues, Melissa Molho, Heng Pan, Boris Bonaventure, Jean-Pierre Quivy, Geneviève Almouzni, Etienne Decroly, Holly Ramage, Jeffrey R. Johnson, Vincent Caval, Nolwenn Jouvenet

Department of Microbiology and Immunology Faculty Papers

Orthoflaviviruses are RNA viruses responsible for significant diseases in humans, domesticated animals, and wildlife. Their NS5 protein is central in viral replication, functioning both as an RNA-dependent RNA polymerase and a methyltransferase, while also modulating cellular processes, including the interferon response. Although viral replication is cytoplasmic, the NS5 protein of several mosquito-borne orthoflaviviruses cycles between the cytoplasm and the nucleus of infected human cells. However, the nuclear localization and function of NS5 of tick-borne orthoflaviviruses, such as tick-borne encephalitis virus (TBEV), remain poorly understood. Microscopy analysis and cell fractionation revealed that the NS5 protein of TBEV localized to both the …

Antigen Discovery In Multiple Myeloma Using Integrated Long-Read Transcriptomics And Immunopeptidomics, Aya Albittar

Dissertations and Theses (Open Access)

Multiple myeloma (MM) remains an incurable plasma cell malignancy, with relapse driven by persistent chemotherapy-resistant cells and residual disease following treatment. Although immunotherapies have transformed MM care, their success depends on identifying tumor-specific antigens that can be safely targeted. While aberrant genomic structural variation and transcriptional dysregulation are increasingly recognized as sources of novel antigens in MM, the HLA-presented antigenic landscape of MM remains incompletely characterized, particularly for non-canonical, structurally-derived peptides, and long-read transcriptome-informed immunopeptidomic data specific to MM remain scarce.

We established an integrated antigen discovery platform combining long-read RNA sequencing (Iso-Seq) with mass spectrometry-based HLA immunoprecipitation and immunopeptidomics …

Development Of Novel Plasminogen Activators From Fragments Of Streptokinase Enzyme, Vijay G Mr

Theses and Dissertations

Thrombotic disorders such as myocardial infarction, ischemic stroke, pulmonary embolism and deep vein thrombosis remain major causes of mortality and disability worldwide, creating a continuing need for effective, safe and affordable thrombolytic therapy. Streptokinase is one of the most widely used plasminogen activators because of its activity, low cost and broad availability. However, its wider clinical utility is limited by high immunogenicity, allergic reactions, neutralizing antibody formation and poor suitability for repeat administration. This thesis aimed to develop novel streptokinase-derived plasminogen activators by identifying smaller functional fragments that retain thrombolytic activity while potentially reducing immunogenicity.

A literature-guided fragment-based strategy was …

Engineering Fsh-Cer T Cells To Enhance Response To Epithelial Ovarian Cancer, Nolan J. Beatty

USF Tampa Graduate Theses and Dissertations

Ovarian cancer remains a significant cause of cancer-related mortality, with epithelial ovarian cancer (EOC) being the most common subtype. Despite advances in treatment, the 5-year survival rate for late-stage EOC remains low due to factors such as tumor heterogeneity and an immunosuppressive tumor microenvironment (TME). This study investigates the therapeutic potential of chimeric endocrine receptor (CER) T cells engineered to express follicle stimulating hormone (FSH) in a syngeneic mouse model of EOC expressing follicle stimulating hormone receptor (ID8-FSHR). We compared two different co-stimulatory domains—CD28ζ and 4-1BBζ—in FSH-CER T cells and found that FSH-CD28ζ CER T cells exhibited enhanced cytotoxicity, proliferation, …

Hemidiaphragmatic Segmental Zoster Paresis, Terrence Sanvictores, Johnson Ukken

School of Medicine Faculty Research

The reactivation of latent varicella-zoster virus within infected neurons can lead to common clinical manifestations, including rash, acute neuritis, post-herpetic neuralgia, herpes zoster ophthalmicus, and Ramsay–Hunt syndrome. Segmental zoster paresis is an unusual neurologic complication of shingles that is defined by focal asymmetric motor weakness in the myotome corresponding to skin lesions of the dermatome. This case is a presentation of a patient who developed chronic hypoxia and severe atelectasis attributed to right-sided phrenic nerve paralysis secondary to herpes zoster infection.
