Acute Disseminated Encephalomyelitis, Ashan T. Hatharasinghe, Hossein Akhondi, Don Pepito

HCA Healthcare Journal of Medicine

Introduction: Acute Disseminated Encephalomyelitis (ADEM) is a rare autoimmune demyelinating disorder of the central nervous system. Clinical manifestations include encephalopathy, motor deficits, ataxia, and meningeal signs. In most cases, ADEM is preceded by either vaccination or viral illness. Here, we present a case with neither of the two predisposing elements.

Discussion: A 28-year-old Hispanic female presenting with substance use and suicidal ideation was placed on an involuntary psychiatric hold, started on olanzapine and scheduled for a psychiatric facility transfer. The following day, she was noted to have neurological deficits when ambulating. Computed tomography of the brain showed a right frontal ...

This paper aims to investigate relative differences in patterns of sensitization in African American ACD patients.

Methods: This study is a retrospective descriptive study. Data of ACD patients patch tested from 2009-2019 by Dr. Gaspari and Dr. Brod at TJUH and HUP/UPHS were reviewed. Patch test findings for African American and Caucasian patients were compared. Outcomes such as positive allergens, strength, clinical relevance, patient occupation, and personal product use ...


Generation And Utilization Of Diverse Memory B Cells After Flavivirus Challenges, Rachel Wong 2019 Washington University in St. Louis

Generation And Utilization Of Diverse Memory B Cells After Flavivirus Challenges, Rachel Wong

Arts & Sciences Electronic Theses and Dissertations

Over the course of an effective immune response to an infection, two distinct B cell populations are generated to provide protection against reinfection, long-lived plasma cells (LLPCs) and memory B cells (MBCs). LLPCs and MBCs originate from germinal center (GC) B cells that have undergone B cell receptor (BCR) affinity maturation through iterative rounds of somatic hypermutation, proliferation, and selection. Thus, LLPCs and MBCs can bind to their antigen with higher affinity than their naïve B cell precursors. LLPCs constitutively secrete antibodies and can provide sterilizing immunity that pre-exists subsequent infections. MBCs, on the other hand, are quiescent and provide ...

The Hiv Vaccine: Learning From Failure And Building On Success, Lindsey Mcclish, Kimberly Gathers, Katie Salay, Lisa Vranekovic, Kristin Seaman, Kelly M. Shields

Pharmacy and Wellness Review

An effective vaccine for acquired immune deficiency syndrome (AIDS) has eluded researchers since the identification of the HIV virus. There are many challenges in developing an effective HIV vaccine, including the lack of knowledge regarding the immune response to the virus and its diverse nature. Ethical concerns further complicate research. A recent phase III trial was performed in Thailand and showed that a significant reduction in HIV infection is possible. Pharmacists need to stay informed of these important breakthroughs in AIDS research in order to provide quality health information to patients in their community. This paper aims to evaluate the ...


Role Of Cd28 Signaling In Mice On Homeostatic Reconstitution On T Cells Following Lymphodepletion, Nitish Sood, Rebecca Crepeau, Mandy Ford 2019 Emory University

Role Of Cd28 Signaling In Mice On Homeostatic Reconstitution On T Cells Following Lymphodepletion, Nitish Sood, Rebecca Crepeau, Mandy Ford

Georgia Undergraduate Research Conference (GURC)

Emory University will soon commence a Phase 2 clinical trial testing the efficacy of Lulizumab, a drug that selectively targets CD28 signaling thereby preventing T cell activation. Preclinical studies have shown this drug to be superior to calcineurin inhibitors in reducing kidney transplant rejection rates. Patients will be T cell depleted (TCD), rendering them lymphopenic at the time of transplant. It is unclear what effect CD28 dAb treatment will have on T cell phenotypes following homeostatic reconstitution (HR) in these patients. Previous studies have shown that HR causes increased differentiation of naïve T cells into memory cells and to premature ...

Polyphenols are naturally occurring compounds that are found within numerous plant sources. They have a wide variety of structures and functions and have potential clinical uses in multiple disease states. Emerging studies involving polyphenols have demonstrated their antioxidative properties, as well as reduced risks of cardiovascular diseases and certain types of cancer. Due to these discoveries, there has been a marked increase in research related to the chemical properties of polyphenols and their potential uses in prevention of common acquired and inherited disease states. This article focuses on the effects that some polyphenolic compounds exert on immune function in regard ...


Understanding The Transcriptional Mechanisms Underlying Dendritic Cell Development, Prachi Bagadia 2019 Washington University in St. Louis

Understanding The Transcriptional Mechanisms Underlying Dendritic Cell Development, Prachi Bagadia

Arts & Sciences Electronic Theses and Dissertations

Dendritic cells (DCs) comprise an important immune lineage that plays a critical role in initiating and sustaining the proper immune response. They can be divided into two distinct branches, classical/conventional DCs (cDCs) or plasmacytoid DCs (pDCs). cDCs can further be classified as cDC1 or cDC2. Each DC subset exerts unique functions in vivo and are necessary for a complete immune response. The precise transcriptional programs underlying DC specification and commitment remain unclear. cDC1, cDC2, and pDC all arise from the common DC progenitor (CDP) in the bone marrow. How the CDP gives rise to all three DC subsets in ...


Secretory Iga Enhances Gut B Cells Priming And Systemic Igg Responses Towards Commensals, You Zhou 2019 Washington University in St. Louis

Secretory Iga Enhances Gut B Cells Priming And Systemic Igg Responses Towards Commensals, You Zhou

Arts & Sciences Electronic Theses and Dissertations

IgA is the primary antibody response at mucosal surfaces and is reported to inhibit adaptive immune responses against gut bacteria. Here, we utilize an in vitro system to expand and screen IgA memory B cells for their ability to recognize gut bacteria in the context of secretory IgA (sIgA) deficiency in polymeric Ig receptor (Pigr–/–) mice. Contrary to the prevailing hypothesis that IgA provides an immune exclusionary function, we found that mice lacking sIgA showed decreased anti-bacterial IgA specificities as assessed using flow cytometry. IgA B cell responses against certain taxa such as those of order Bacteriodales showed greater dependence ...


Mesothelium-Derived Factors Shape Tissue Resident Macrophage, Chin-Wen Lai 2019 Washington University in St. Louis

Mesothelium-Derived Factors Shape Tissue Resident Macrophage, Chin-Wen Lai

Arts & Sciences Electronic Theses and Dissertations

The studies outlined in this thesis provide several new insights into Msln-related pathways necessary for peritoneal immune responses and mucosal repair. We found that Msln and its binding partner mucin 16 from mesothelium influenced peritoneal and pleural macrophage differentiation. We found that Msln was required for proper tissue repair after colonic biopsy injury and was required for maximal polyp growth in APCMin/+ mice. Overall, this work describes mesothelial and epithelial-derived factors that are important for tissue resident macrophage differentiation and wound repair after colonic mucosal injury. Understanding the complex interactions between stromal cells and immune cells will lead to better ...

INTRODUCTION: Pathologic accumulation and activation of mast cells and eosinophils are implicated in allergic and inflammatory diseases. Sialic acid-binding immunoglobulin-like lectin (Siglec)-8 is an inhibitory receptor selectively expressed on mast cells, eosinophils and, at a lower extent, basophils. When engaged with an antibody, Siglec-8 can induce apoptosis of activated eosinophils and inhibit mast cell activation. AK002 is a humanized, non-fucosylated IgG1 anti-Siglec-8 antibody undergoing clinical investigation for treatment of allergic, inflammatory, and proliferative diseases. Here we examine the human tissue selectivity of AK002 and evaluate the in vitro, ex vivo, and in vivo activity of AK002 on eosinophils and ...

Diabetes mellitus (DM) increases risk for pulmonary tuberculosis (TB) and adverse treatment outcomes. Systemic hyper-inflammation is characteristic in people with TB and concurrent DM (TBDM) at baseline, but the impact of TB treatment on this pattern has not been determined. We measured 17 plasma cytokines and growth factors in longitudinal cohorts of Indian and Brazilian pulmonary TB patients with or without DM. Principal component analysis revealed virtually complete separation of TBDM from TB individuals in both cohorts at baseline, with hyper-inflammation in TBDM that continued through treatment completion at six months. By one year after treatment completion, there was substantial ...


Modulation Of Inflammation Driven Wound Healing After Glaucoma Surgery, James J. Armstrong 2019 The University of Western Ontario

Modulation Of Inflammation Driven Wound Healing After Glaucoma Surgery, James J. Armstrong

Electronic Thesis and Dissertation Repository

Dysregulated wound healing contributes to most currently unanswered ophthalmological morbidity. Opacification and structure altering contractures compromise the delicate ocular anatomy upon which ocular function and healthy vision are reliant. Glaucoma filtration surgery, corneal stromal injury, proliferative vitreoretinopathy and age-related macular degeneration are major contributors to ocular morbidity – all with myofibroblast transdifferentiation and pathognomonic scarring activity at their core.

This thesis aims to revaluate the means by which dysregulated ocular wound healing is combated with evidence describing a novel strategy to mitigate its effects. A translational approach was used. An initial retrospective analysis of over ten thousand glaucoma surgeries found that ...

Development of specific IgE antibodies to the oligosaccharide galactose-α-1, 3-galactose (α-gal) following tick bites has been shown to be the source of red meat allergy. In this study, we investigated the presence of α-gal in four tick species: the lone-star tick (Amblyomma americanum), the Gulf-Coast tick (Amblyomma maculatum), the American dog tick (Dermacentor variabilis), and the black-legged tick (Ixodes scapularis) by using a combination of immunoproteomic approach and, carbohydrate analysis. Anti-α-gal antibodies identified α-gal in the salivary glands of both Am. americanum and Ix. scapularis, while Am. maculatum and De. variabilis appeared to lack the carbohydrate. PNGase F treatment confirmed ...

Characterizing The Humoral Response To Flavivirus Infection, Estefania Fernandez 2019 Washington University in St. Louis

Characterizing The Humoral Response To Flavivirus Infection, Estefania Fernandez

Arts & Sciences Electronic Theses and Dissertations

Flaviviruses are positive (+) sense, single-stranded RNA viruses of the Flaviviridae family that are transmitted by mosquitoes. For our studies, we focused on Zika virus (ZIKV) and Japanese encephalitis virus (JEV). Most human infections with ZIKV historically resulted in a mild self-limiting febrile illness. However, since 2013, a worldwide spread and increase in ZIKV infections has been observed. Notably, ZIKV has been associated with autoimmune ascending paralysis (Guillain-Barré Syndrome) and ophthalmologic effects in adults and intrauterine growth restriction and microcephaly in developing fetuses. Current vaccine efforts utilize technologies implemented for related flaviviruses (yellow fever virus (YFV), Dengue virus (DENV), and JEV ...


Development Of Enteric Neurons And Muscularis Macrophages, Marina Avetisyan 2019 Washington University in St. Louis

Development Of Enteric Neurons And Muscularis Macrophages, Marina Avetisyan

Arts & Sciences Electronic Theses and Dissertations

The enteric nervous system (ENS) is a complex interconnected network of neurons and glia in the bowel wall that regulates intestinal motility, blood flow, and epithelial function. The ENS also controls aspects of inflammatory signaling within the bowel. To perform these tasks, there are at least 20 types of enteric neuron and four types of enteric glia. Although much is known about early events in ENS development, signals governing the development of specific neuronal subtypes and communication with neighboring cell types within the bowel remain poorly understood. One fundamental hypothesis is that diverse trophic factors support distinct neuronal populations in ...
