Trypanosoma cruzi is a protozoan parasite that causes Chagas disease. Globally 6 to 7 million people are infected by this parasite of which 20-30% will progress to develop Chronic Chagasic Cardiomyopathy (CCC). Despite its high disease burden, no clinically approved vaccine exists for the prevention or treatment of CCC. Developing vaccines that can stimulate T. cruzi-specific CD8+ cytotoxic T cells and eliminate infected cells requires targeting parasitic antigens presented on major histocompatibility complex-I (MHC-I) molecules. We utilized mass spectrometry-based immunopeptidomics to investigate which parasitic peptides are displayed on MHC-I of T. cruzi infected cells. Through duplicate experiments, we identified an …

A New Ex Vivo Model System To Analyze Factors Affecting The Integrity Of Fetal Membranes In Fetoscopic Surgery, Serjosha Robmann, Raoul Hopf, Costanza Giampietro, Lukas Moser, Alexandra Dolder, Magdalena Sanz Cortes, Martin Ehrbar, Nicole Ochsenbein, Jan Deprest, Edoardo Mazza

Faculty, Staff and Students Publications

We developed an ex vivo model system to analyze the influence of relevant environmental and mechanical factors potentially affecting the integrity of fetal membranes during fetoscopic surgery. The set-up exposes amniochorion membranes to insufflation at predefined levels of gas pressure, flow, humidity, and temperature. Change in fetal membranes stiffness is quantified during the phase mimicking surgery through measurement of membranes' strain in response to cyclic overpressure. The trocar induced perforation creates a mechanical weakness whose stability is assessed by increasing the insufflation pressure until membrane rupture. Damage of the epithelial cells lining the amnion is assessed through live-dead staining. Initial …

Faculty Research, Scholarly, and Creative Activity

The mobile nature of migratory marine animals across jurisdictional boundaries can challenge the management of biodiversity, particularly under global environmental change. While projections of climate-driven habitat change can reveal whether marine species are predicted to gain or lose habitat in the future, geopolitical boundaries and differing governance regimes may influence animals’ abilities to thrive in new areas. Broad geographic movements and diverse governance approaches elicit the need for strong international collaboration to holistically manage and conserve these shared migratory species. In this study, we use data from the Tagging of Pacific Predators program to demonstrate the feasibility of using climate-driven …

Impact Of Pegylated Liposomes On Cytotoxicity Of Tamoxifen And Piperine On Mcf-7 Human Breast Carcinoma Cells, Klaudi K. Vaiphei, A Prabakaran, Singh Snigdha, Satyajit Laxman Murkute, Purusottam Mohapatra, Rakesh Kumar Sahoo, Sanya Batheja, Umesh Gupta, Anu Puri, Upal Roy

Health & Biomedical Sciences Faculty Publications

Tamoxifen (TMF) is an anticancer agent used for managing estrogen receptor-positive breast cancer. It has limited therapeutic efficacy against breast cancer, which could be enhanced by the coadministration of herbal drugs like piperine (PIP). However, the hydrophobic nature of TMF and PIP restricts their therapeutic application. Therefore, the present study focuses on the impact of the anticancer activity of TMF in combination with PIP and after entrapping them into liposomes (TMF-PIP-LPs and TMF-PIP-PEG-LPs). The liposomes were prepared using the thin film hydration method. In addition, the morphology of the prepared liposomes was found spherical after SEM and TEM analyses. Further, …

Anaplasma Phagocytophilum’S Effect On Gopher Tortoises Of South East Florida, Elena Tonkin

Harriet L Wilkes Honors College Theses 2020 - Present

Recent studies have revealed Anaplasma phagocytophilum as a new pathogen that has started to affect gopher tortoise populations throughout Florida. This study investigated how the pathogen, A. phagocytophilum, has potentially begun to spread amongst the gopher tortoises in the Abacoa Greenway and the Florida Atlantic University Preserve (FAUP). To investigate these tortoises, blood samples were taken from multiple specimens from Range VI of the Greenway and FAUP. DNA isolated from these samples were then analyzed for the presence of A.phagocytophilum utilizing PCR and gel electrophoresis, followed by Sanger sequencing. This research demonstrated that A.phagocytophilum has not made its way …

Redox Regulation Of Proteostasis, Long Duy Duong, James D West, Kevin A Morano

Faculty, Staff and Student Publications

Oxidants produced through endogenous metabolism or encountered in the environment react directly with reactive sites in biological macromolecules. Many proteins, in particular, are susceptible to oxidative damage, which can lead to their altered structure and function. Such structural and functional changes trigger a cascade of events that influence key components of the proteostasis network. Here, we highlight recent advances in our understanding of how cells respond to the challenges of protein folding and metabolic alterations that occur during oxidative stress. Immediately after an oxidative insult, cells selectively block the translation of most new proteins and shift molecular chaperones from folding …

Nasal Virus Infection Induces Asthma Exacerbation Through B-Cell-Dependent Recruitment Of Inflammatory Monocytes, Kody A Waldstein, Arman Issimov, Maria Ganama, Valerie Jinge, Stephen Tilley, Xiaoyang Hua

Faculty, Staff and Student Publications

Background: Upper respiratory viral infections (URVIs) are responsible for 80% of asthma exacerbation episodes. However, the underlying mechanisms remain poorly understood.

Methods: In this study, we used a mouse model of URVI and examined the impact of URVI on asthma phenotypes and the underlying mechanisms.

Results: Previously, we have reported that nasal-restricted infection with respiratory syncytial virus (RSV) only produces mild sino-nasal inflammation and mucus production, without causing direct lung infection. However, such nasal-restricted infection dramatically enhanced TH2 and TH17 inflammatory responses in the lungs and increased airway hyperresponsiveness (AHR) in mice with house dust mite (HDM)-induced asthma. Additionally, nasal-restricted …

Williams syndrome (WS) is a rare multisystemic disorder caused by recurrent microdeletions on 7q11.23, characterized by intellectual disability, distinctive craniofacial and dental features, and cardiovascular problems. Previous studies have explored the roles of individual genes within these microdeletions in contributing to WS phenotypes. Here, we report five patients with WS with 1.4 Mb-1.5 Mb microdeletions that include RFC2, as well as one patient with a 167-kb microdeletion involving RFC2 and six patients with intragenic variants within RFC2. To investigate the potential involvement of RFC2 in WS pathogenicity, we generate a rfc2 knockout (KO) zebrafish using CRISPR-Cas9 technology. Additionally, we generate …

Fibrolytic Vaccination Against Adam12 Reduces Desmoplasia In Preclinical Pancreatic Adenocarcinomas, Jing Chen, David Denardo, Et Al.

2020-Current year OA Pubs

A hallmark feature of pancreatic ductal adenocarcinoma (PDAC) is massive intratumoral fibrosis, designated as desmoplasia. Desmoplasia is characterized by the expansion of cancer-associated fibroblasts (CAFs) and a massive increase in extracellular matrix (ECM). During fibrogenesis, distinct genes become reactivated specifically in fibroblasts, e.g., the disintegrin metalloprotease, ADAM12. Previous studies have shown that immunotherapeutic ablation of ADAM12

Oscillometry Changes Reflect Clinically Meaningful Improvement After Bronchial Thermoplasty For Uncontrolled Asthma: A Case Report, Niranjan Setty, Alice Crawford, Brooke Kyle, Dhaval Thakkar, Rajesh Thomas, John Blakey

Research outputs 2022 to 2026

Asthma is a highly prevalent but heterogenous condition. Uncontrolled disease is relatively common and may be due to ongoing inflammation and/or persisting bronchial hyper-reactivity. Bronchial thermoplasty has been in use for many years but optimal case selection and post-procedure assessment remain uncertain. We present a case of a gentleman in his 50s with lifelong asthma who experienced a persistent loss of control following influenza A in 2017. Despite multidisciplinary assessment and guideline-based escalation of therapy, he had persisting symptoms. In the context of his atopy, he was trialled unsuccessfully on dupilumab. Bronchial thermoplasty (BT) was undertaken with good clinical benefit. …

Crosstalk Between Cytokines And Igg N-Glycosylation: Bidirectional Effects And Relevance To Clinical Innovation For Inflammatory Diseases, Zhixian Chen, Xiaojia Xu, Manshu Song, Ling Lin

Research outputs 2022 to 2026

The crosstalk between cytokines and immunoglobulin G (IgG) N-glycosylation forms a bidirectional regulatory network that significantly impacts inflammation and immune function. This review examines how various cytokines, both pro- and anti-inflammatory, modulate IgG N-glycosylation, shaping antibody activity and influencing inflammatory responses. In addition, we explore how altered IgG N-glycosylation patterns affect cytokine production and immune signaling, either promoting or reducing inflammation. Through a comprehensive analysis of current studies, this review underscores the dynamic relationship between cytokines and IgG N-glycosylation. These insights enhance our understanding of the mechanisms underlying inflammatory diseases and contribute to improved strategies for disease prevention, diagnosis, monitoring, …

2020-Current year OA Pubs

BACKGROUND: Pulmonary fibrosis is a challenging clinical problem with lung pathology featuring immune cell infiltrates, fibroblast expansion, and matrix deposition. Molecular analysis of diseased lungs and preclinical models have uncovered C-C chemokine receptor type 2 (CCR2)+ monocyte egress from the bone marrow into the lung, where they acquire profibrotic activities. Current drug treatment is focused on fibroblast activity. Alternatively, therapeutic targeting and monitoring CCR2+ cells may be an effective patient management strategy.

METHODS: Inhibition of CCR2+ cells and, as a benchmark, the clinical antifibrotic agent, nintedanib, were used in mouse lung fibrosis models. Lungs were evaluated directly for CCR2+ cell …

2020-Current year OA Pubs

BACKGROUND: Endothelial cell (EC)-pericyte interactions are known to remodel in response to hemodynamic forces; yet there is a lack of mechanistic understanding of the signaling pathways that underlie these events. Here, we have identified a novel signaling network regulated by blood flow in ECs-the chemokine receptor CXCR3 (CXC motif chemokine receptor 3) and one of its ligands, CXCL11 (CXC motif chemokine ligand 11)-that delimits EC angiogenic potential and promotes pericyte recruitment to ECs during development.

METHODS: We investigated the role of CXCR3 on vascular development using both 2- and 3-dimensional in vitro assays, to study EC-pericyte interactions and EC behavioral …

The Long Road Of Drug Development For Endometriosis – Pains, Gains, And Hopes, Zian Liao, Diana Monsivais, Martin M Matzuk

Faculty, Staff and Students Publications

Endometriosis, defined by the growth of endometrial tissues outside of the uterine cavity, is a global health burden for ∼200 million women. Patients with endometriosis usually present with chronic pain and are often diagnosed with infertility. The pathogenesis of endometriosis is still an open question; however, tissue stemness and immunological and genetic factors have been extensively discussed in the establishment of endometriotic lesions. Current treatments for endometriosis can be categorized into pharmacological management of hormone levels and surgical removal of the lesions. Both approaches have limited efficacy, with recurrences often encountered; thus, there is no complete cure for the disease …

Emergent Microenvironments Of Nucleoli, Matthew R King, Kiersten M Ruff, Rohit V Pappu

2020-Current year OA Pubs

In higher eukaryotes, the nucleolus harbors at least three sub-phases that facilitate multiple functionalities including ribosome biogenesis. The three prominent coexisting sub-phases are the fibrillar center (FC), the dense fibrillar component (DFC), and the granular component (GC). Here, we review recent efforts in profiling sub-phase compositions that shed light on the types of physicochemical properties that emerge from compositional biases and territorial organization of specific types of macromolecules. We highlight roles played by molecular grammars which refers to protein sequence features including the substrate binding domains, the sequence features of intrinsically disordered regions, and the multivalence of these distinct types …

Retinal Ganglion Cell Circuits And Glial Interactions In Humans And Mice, Kang-Chieh Huang, Mohamed Tawfik, Melanie A Samuel

Faculty, Staff and Students Publications

Retinal ganglion cells (RGCs) are the brain's gateway for vision, and their degeneration underlies several blinding diseases. RGCs interact with other neuronal cell types, microglia, and astrocytes in the retina and in the brain. Much knowledge has been gained about RGCs and glia from mice and other model organisms, often with the assumption that certain aspects of their biology may be conserved in humans. However, RGCs vary considerably between species, which could affect how they interact with their neuronal and glial partners. This review details which RGC and glial features are conserved between mice, humans, and primates, and which differ. …

Chemogenetic Neuronal Silencing Decouples C-Jun Activation From Cell Death In The Temporal Cortex, Caleb A Wood, Preethi Somasundaram, Jacob M Dundee, Melissa A Rudy, Trent A Watkins, Joanna L Jankowsky

Faculty, Staff and Students Publications

Initial symptoms of neurodegenerative diseases are often defined by the loss of the most vulnerable neural populations specific to each disorder. In the early stages of Alzheimer's disease, vulnerable circuits in the temporal lobe exhibit diminished activity prior to overt degeneration. It remains unclear whether these functional changes contribute to regional vulnerability or are simply a consequence of pathology. We previously found that entorhinal neurons in the temporal cortex undergo cell death following transient suppression of electrical activity, suggesting a causal role for activity disruption in neurodegeneration. Here we demonstrate that electrical arrest of this circuit stimulates the injury-response transcription …

Bst2 Facilitates Activation Of Hematopoietic Stem Cells Through Erk Signaling, Marcus A Florez, Apoorva Thatavarty, Duy T Le, Holly A Hill, Youngjae Jeong, Brian M Ho, Pawel Kus, Trisha K Wathan, Bailee N Kain, Shixia Huang, Dongsu Park, Katherine Y King

Faculty, Staff and Students Publications

The proinflammatory cytokine interferon-gamma (IFNγ) is upregulated in a variety of infections and contributes to bone marrow failure through hematopoietic stem cell (HSC) activation and subsequent exhaustion. The cell surface protein, bone marrow stromal antigen 2 (BST2), is a key mediator of this process, as it is induced upon interferon stimulation and required for interferon-dependent HSC activation. To identify the mechanism by which BST2 promotes interferon-dependent HSC activation, we evaluated its role in niche localization, immune cell function, lipid raft formation, and intracellular signaling. Our studies indicated that knock out (KO) of BST2 in a murine model does not disrupt …

Faculty, Staff and Students Publications

Osteogenesis imperfecta (OI) is a Mendelian connective tissue disorder associated with increased bone fragility and other clinical manifestations most commonly due to abnormalities in production, structure, or post-translational modification of type I collagen. Until recently, most research in OI has focused on the pediatric population and much less attention has been directed at the effects of OI in the adult population. This is a narrative review of the literature focusing on the skeletal as well as non-skeletal manifestations in adults with OI that may affect the aging individual. We found evidence to suggest that OI is a systemic disease which …

Aging-Associated Mechanisms Of Atrial Fibrillation Progression And Their Therapeutic Potential, Shuai Zhao, Aaron M Johnston, Chi Him Kendrick Yiu, Lucia M Moreira, Svetlana Reilly, Xander H T Wehrens

Faculty, Staff and Students Publications

Atrial fibrillation (AF) is the most common sustained arrhythmia, with a particularly high prevalence in the elderly. As the global aging population rapidly expands, it is increasingly important to examine how alterations to the aging heart contribute to an increased AF susceptibility. This work critically reviews the key molecular mechanisms that may underpin the complex association between aging and AF. Moreover, we identify emerging novel opportunities for therapeutic intervention that may be able to prevent and/or improve the current treatment paradigms for age-related AF. This review contributes to a holistic understanding of the intricate relationship between aging and AF.
