Can Viruses Cause Lupus?, Stephen I. Reeder
Can Viruses Cause Lupus?, Stephen I. Reeder
Selected Honors Theses
Like so many autoimmune diseases, the exact cause of systemic lupus erythematosus (SLE) remains unknown. Evidence points to both genetics and environment playing roles in the onset of the disease, but neither acts independent of the other. Genetics are the easier of the two to study with recent advances in the field making it easier to isolate genes shared by individuals with the disease. However, genetic studies reveal that there is almost certainly an environmental component to the development of SLE. The underlying pathology and existing research on environmental contributors to the development of SLE suggest that viruses could potentially …
Cancer-Targeting Immunostimulatory Peptides As An Immunotherapeutic Approach To Cancer, Rachel Montel
Cancer-Targeting Immunostimulatory Peptides As An Immunotherapeutic Approach To Cancer, Rachel Montel
Seton Hall University Dissertations and Theses (ETDs)
This dissertation reports the synthesis and biological applications of bifunctional trimeric peptides with B7H6-derived NKp30 binding motifs that serve to activate an immunocytotoxic response in natural killer cells and a GRP78-binding motif that can target tumors that express surface GRP78. In this manner the cancer-targeting immunostimulatory peptides are anticipated to directly bind and activate effector NK92-MI cells while also recognizing and binding to target A549 tumor cells to facilitate NK cell-dependent immunocytotoxicity of the targeted tumors. The NKp30 binding peptide motifs are derived from the tumor associated B7H6 antigen that is often downregulated or shed from the surface of tumors …
Development, Expansion And Role Of Myeloid-Derived Suppressor Cells In Post-Sepsis Immune Suppression, Tuqa Alkhateeb
Development, Expansion And Role Of Myeloid-Derived Suppressor Cells In Post-Sepsis Immune Suppression, Tuqa Alkhateeb
Electronic Theses and Dissertations
Myeloid-derived suppressor cells (MDSCs) numbers increase significantly in sepsis and are associated with high mortality rates. These myeloid cell precursors promote immunosuppression, especially in the late (post sepsis) stage. However, the mechanisms that underlie MDSC expansion and programming are not completely understood. To investigate these mechanisms, we used a cecal-ligation and puncture (CLP) mouse model of polymicrobial sepsis that progresses from an early/acute proinflammatory phase to a late/chronic immunosuppressive phase. Previous studies in our laboratory showed that microRNA (miR)-21 and miR-181b elevate levels of the transcription factor nuclear factor 1 (NFI-A) that promotes MDSC expansion. We report here that miR-21 …

HIV-1 is the etiological agent behind acquired immune deficiency syndrome (AIDS) – a chronic, life-threatening condition that compromises host immune function. After nearly four decades and despite ongoing global efforts, HIV-1 persists in nearly 38 million individuals worldwide. Of this population, only 60% have access to life-saving combination antiretroviral therapy (cART), clearly emphasizing the need to realize a cure. Unfortunately, the establishment of replication-competent provirus in resting CD4+ T lymphocytes represents a significant barrier to HIV-1 curative research. The viral reservoir is highly stable and has a half-life of ~44 months. Therefore, it is unlikely that infection will naturally exhaust …
Investigating The Interactions Between Individual Calmodulin And Hiv-1 Protein Domains, Riley K. Kendall, Jerry Larue
Investigating The Interactions Between Individual Calmodulin And Hiv-1 Protein Domains, Riley K. Kendall, Jerry Larue
Student Scholar Symposium Abstracts and Posters
The World Health Organization found that 37.9 million people were living with HIV by the end of 2018. HIV is a virus that weakens the immune system through viral replication and the destruction of CD4+ T-cells, which are white blood cells that detect infection and make antibodies. A cure for HIV has not yet been discovered. HIV-1 contains a Gag polyprotein which regulates the stages of viral replication. Previous studies suggest that the myristoyl group of a matrix protein peptide found on the Gag polyprotein, MA, forms a complex with a calcium-binding, multifunctional regulatory protein called Calmodulin (CaM). CaM …

Targeting Natural Killer Cells For Improved Immunity And Control Of The Adaptive Immune Response., Stephen Pierce, Eric S. Geanes, Todd Bradley
Manuscripts, Articles, Book Chapters and Other Papers
Natural killer (NK) cells are critical for targeting and killing tumor, virus-infected and stressed cells as a member of the innate immune system. Recently, NK cells have also emerged as key regulators of adaptive immunity and have become a prominent therapeutic target for cancer immunotherapy and infection control. NK cells display a diverse array of phenotypes and function. Determining how NK cells develop and are regulated is critical for understanding their role in both innate and adaptive immunity. In this review we discuss current research approaches into NK cell adaptive immunity and how these cells are being harnessed for improving …
Gut Pathophysiology In Mouse Models Of Social Behavior Deficits, Kyla Scott
Gut Pathophysiology In Mouse Models Of Social Behavior Deficits, Kyla Scott
Undergraduate Honors Theses
Autism spectrum disorders (ASD) encompass neurodevelopment disorders characterized by atypical patterns of development that impact multiple areas of functioning beginning in early childhood. The etiology of ASD is unknown and there are currently no preventative treatment options. Gastrointestinal symptoms are commonly associated comorbidities. The microbiota-gut-brain axis is a multidirectional communication chain that connects the central and enteric nervous system that relates brain function to peripheral intestinal functions. Changes within this axis have been postulated in ASD. For example, the “leaky gut theory” proposes that chronic inflammation is linked to alterations in the bacterial profiles of the gut microbiome and subsequent …
The Role Of Nutrition In Promoting Gut Health And Treating Chronic Illness Through The Attenuation Of Inflammation, Allison Dalton
The Role Of Nutrition In Promoting Gut Health And Treating Chronic Illness Through The Attenuation Of Inflammation, Allison Dalton
HCA Healthcare Journal of Medicine
Over the millennia, the human body and microorganisms such as bacteria, viruses, archaea, protozoa and parasites have coevolved together forming an intimate relationship. These microorganisms are found on the skin, in the mouth, genitourinary tract and most abundantly in the large intestine of the digestive tract. States of microbial dysbiosis contribute to chronic inflammation, which can lead to the pathogenesis and progression of numerous diseases. Micro- and macro-nutrients as well as dietary patterns like the Mediterranean diet can help improve health outcomes.
Vaccines In Current Culture: The Hpv Vaccine Controversy, Alyssa Johnston
Vaccines In Current Culture: The Hpv Vaccine Controversy, Alyssa Johnston
Senior Honors Theses
The use of vaccinations has drastically decreased mortality and morbidity rates related to infectious disease and has become an intrinsic part of modern health care. However, the fear of risks related to vaccines has been partially responsible for the decisions of many parents to delay or avoid vaccinating their children. The human papilloma virus (HPV) vaccine specifically is one of the most controversial vaccines in current culture due to reports of new onset or exacerbation of autoimmune diseases, infertility, and even death following its administration. This review synthesizes information regarding the relevance and safety of the HPV vaccine, as well …

Post-Surgical Pyoderma Gangrenosum After Breast Surgery: A Case Series, Jahan Tajran, Daniella Anderson, Arif Chaudhry, Dennis Hammond
Medical Student Research Symposium
Background:
Pyoderma gangrenosum (PG) is a rare inflammatory cutaneous disorder that is thought to be due to innate immune system dysfunction, specifically of neutrophils. PG has been well documented in patients with autoimmune disorders like Ulcerative Colitis and Rheumatoid Arthritis. PG can also present in surgical patients, imitating a potential wound infection and necrotizing fasciitis. Although PG is a diagnosis of exclusion, prompt recognition is essential to attaining desired aesthetic outcomes, especially with breast involvement. We present a case series of four patients who developed PG following breast surgery. We analyze each patient’s medical history, symptoms, wound progression and management …
The Interplay Of The Oral-Gut Microbiome With Chronic Inflammation In Rheumatoid Arthritis And Crohn's Disease, Anuradha Rampersaud
The Interplay Of The Oral-Gut Microbiome With Chronic Inflammation In Rheumatoid Arthritis And Crohn's Disease, Anuradha Rampersaud
Mako: NSU Undergraduate Student Journal
Abstract
Rheumatoid Arthritis (RA) and Crohn’s Disease (CD) are both chronic inflammatory diseases that share developmental and treatment similarities. RA’s symptoms include swelling, stiffness, and pain in synovial joints, corresponding with bone and cartilage destruction. CD’s symptoms include abdominal pain, bowel obstruction, bloating, diarrhea, and fever. The purpose of this literature review was to investigate the links between these two diseases and propose future treatment and prevention targets. Current treatment for RA and CD aims to suppress inflammation by targeting its mediators. However, this review noted that there should be greater focus on resolving inflammation. Both diseases are characterized by …

Identification Of The Kaposi's Sarcoma-Associated Herpesvirus (Kshv) Surface Glycoprotein Targets Of Human Kshv-Specific Neutralizing Antibody Responses, Yasaman Mortazavi
School of Biological Sciences: Dissertations, Theses, and Student Research
Kaposi’s sarcoma-associated herpesvirus (KSHV), also known as human herpesvirus 8 (HHV-8), is the etiological agent of Kaposi’s sarcoma (KS), and is also associated with two B cell malignancies, primary effusion lymphoma and multicentric Castleman's disease. The distribution of KSHV varies globally with high prevalence in some areas of sub-Saharan Africa (SSA), where seroprevalence can be as high as 80%. It is estimated that nearly 44,000 new cases of KS emerge annually globally, with the highest incidents occurring in Africa, where KSHV is endemic. Currently, there is no prophylactic vaccine against KSHV, and efforts to develop prophylactic vaccines have been limited. …
Prophylaxis Of Food Allergen Sensitivity, Dustin Gottfeld
Prophylaxis Of Food Allergen Sensitivity, Dustin Gottfeld
Physician Assistant Studies | Student Articles
Food allergies can have a severe and drastic effect on a person’s lifestyle, while prevention of allergic disease can help to ensure others do not have to live with this burden. There are a variety of differing hypotheses that offer explanations for the early development of food allergies, particularly peanut allergies. Two of the foremost hypotheses are the Hygiene Hypothesis and the Dual-Allergen Hypothesis. The Hygiene Hypothesis claims that the diversity of a child’s microbiota creates a beneficial balance of microorganisms which can help prevent the development of allergic disease. Alternatively, the Dual-Allergen Hypothesis states that early environmental exposure to …
Quantifying The Heterogeneity Of The Immunoglobulin G N-Glycome In An Ageing Australian Population: The Busselton Healthy Ageing Study, Alyce Russell
Quantifying The Heterogeneity Of The Immunoglobulin G N-Glycome In An Ageing Australian Population: The Busselton Healthy Ageing Study, Alyce Russell
Theses: Doctorates and Masters
The use of immunoglobulin G N-glycomics to study chronic non-communicable disorders and other complex phenotypes emerged following the Human Genome Project. The consortium discovered that most phenotypes were too complex to be explained by genetics alone. Thus, the biological importance of epigenetics was recognised; heritable modifications to gene expression rather than the genome itself. Nglycosylation is a form of epigenetic regulation known as a post-translational modification. It stabilises the immunoglobulin G structure and alters downstream responses elicited by the antibody and is extensively studied as a candidate biomarker in the post-genomic era.
The N-glycosylation of immunoglobulin G itself is complex, …
