Development Of A Pd-L1 Pet Imaging Biomarker, Caleb Jack Bridgwater 2018 University of Louisville

Development Of A Pd-L1 Pet Imaging Biomarker, Caleb Jack Bridgwater

Posters-at-the-Capitol

Immunotherapy strategies are very promising treatments for cancer patients. Specifically, Immune checkpoint inhibitor therapy focusing on the PD-1/PD-L1 pathway shows long-lasting positive results in many cancer patients. Unfortunately, not all the patients can benefit from this highly effective treatment. Hence, there is a great need for predictive biomarkers. Immunohistochemical (IHC) staining has been used as a way of predicting patient response, yet shows many problems. For example, IHC utilizes an invasive biopsy and sample fixing, which creates an incomplete and delayed picture of the patient’s biochemistry and the tumor microenvironment, consequently ignoring metastases.

The purpose of this study ...

Enhancing Immunization Rates At Aurora Family Medicine Clinics In Milwaukee, Wisconsin, Zeeshan A. Yacoob, Christopher Cook, Jessica J.F. Kram, Marianne Klumph, Dennis J. Baumgardner, Marisa Stanley, Paul Hunter, Fabiana Kotovicz

Journal of Patient-Centered Research and Reviews

Background: In the United States, only 72.2% of children (age 19–35 months) are up-to-date on all of their immunizations. This rate is even lower for children from impoverished households (68.7%). Lack of encouragement by providers, as well as parent perceptions of vaccine safety and efficacy, have been cited as some of the reasons for lower vaccination rates.

Purpose: Our study aimed to collect and compare patient demographic data to age appropriate and comorbidity-specific vaccination rates.

Methods: We conducted a quality improvement study at Family Practice Center (Aurora St. Luke’s Medical Center, Milwaukee, WI) and Family Care ...


Cd4 T Cell Interaction With Intestinal Microbes Under Homeostasis And Inflammation, Jiani Chai 2018 Washington University in St. Louis

Cd4 T Cell Interaction With Intestinal Microbes Under Homeostasis And Inflammation, Jiani Chai

Arts & Sciences Electronic Theses and Dissertations

Specific gut commensal bacteria improve host health by eliciting mutualistic regulatory T (Treg) cells responses. However, the bacteria that induce effector T (Teff) cells during inflammation are unclear. Here, we addressed this by analyzing bacterial-reactive T cell receptor (TCR) transgenic cells and TCR repertoires in a murine colitis model. Unexpectedly, we found that mucosal-associated Helicobacter species triggered both Treg responses during homeostasis and Teff responses during colitis, as suggested by an increased overlap between the Teff/Treg TCR repertoires with colitis. In fact, 4/6 Treg TCRs tested recognized mucosal-associated Helicobacter species in vitro and in vivo. By contrast, the ...


Identification Of Bhlhe40 And Irg1 As Essential Regulators Of The Inflammatory Response To Mycobacterium Tuberculosis, Jeremy Peter Huynh 2018 Washington University in St. Louis

Identification Of Bhlhe40 And Irg1 As Essential Regulators Of The Inflammatory Response To Mycobacterium Tuberculosis, Jeremy Peter Huynh

Arts & Sciences Electronic Theses and Dissertations

Protective immune responses to Mycobacterium tuberculosis (Mtb) must induce bactericidal functions while minimizing damage to the lung. Such responses require precise control of pro- and anti-inflammatory factors to regulate the recruitment and function of protective immune cells but the mechanisms by which this control is exerted remain incompletely defined. Basic helix-loop-helix family, member e40 (Bhlhe40) is a transcription factor known to regulate production of pro- and anti-inflammatory cytokines that affect protective immunity to Mtb. Immune-responsive Gene 1 (Irg1) is an enzyme that generates itaconate, a metabolite with potential anti-inflammatory and antibacterial roles during Mtb infection. The impact of Bhlhe40 and ...

Open Access Articles

Background. Enterotoxigenic Escherichia coli (ETEC) cause diarrheal illness in infants in the developing world and travelers to endemic countries including military personnel. ETEC infection of the host involves colonization of the small intestinal epithelium and toxin secretion leading to watery diarrhea. There is currently no vaccine licensed to prevent ETEC. CFA/I is one of the most common colonization factor antigens (CFAs). The CFA/I adhesin subunit, CfaE, is required for ETEC adhesion to host intestinal cells. Human antibodies against CfaE have potential to block colonization of ETEC and serve as an immunoprophylactic against ETEC-related diarrhea.

Methods. Mice transgenic for ...


Tumors Interrupt Irf8-Mediated Dendritic Cell Development To Overcome Immune Surveillance, Melissa Ann Meyer 2018 Washington University in St. Louis

Tumors Interrupt Irf8-Mediated Dendritic Cell Development To Overcome Immune Surveillance, Melissa Ann Meyer

Arts & Sciences Electronic Theses and Dissertations

Tumors employ multiple mechanisms to evade immune surveillance. One mechanism is tumor-induced myelopoiesis, which expands immune suppressive granulocytes and monocytes to create a protective tumor niche shielding even antigenic tumors. As myeloid cells and immune-stimulatory conventional dendritic cells (cDCs) are derived from the same progenitors, it is logical that tumor-induced myelopoiesis might also impact cDC development. The cDC subset cDC1 is marked by CD141 in humans and CD103 or CD8α in mice. cDC1s act by cross presenting antigen and activating CD8+ T cells. Given these functions, CD103+ cDC1s can support anti-tumor CD8+ T cell responses. However, CD103+ cDC1 numbers are ...


Negative Regulators Of Colonic Peripheral Regulatory T Cell Development, Teresa Lei Ai 2018 Washington University in St. Louis

Negative Regulators Of Colonic Peripheral Regulatory T Cell Development, Teresa Lei Ai

Arts & Sciences Electronic Theses and Dissertations

Peripheral Treg cells (pTreg cells) maintain immune homeostasis at mucosal interfaces, where they can develop upon activation of naïve CD4+ T cells by bacteria antigen. However, the cellular and molecular requirements that govern their differentiation in inflamed and homeostatic contexts require further elucidation. To circumvent uncertainties in existing methods of distinguishing pTreg cells from thymic Treg cells (tTreg cells), we analyzed monoclonal cell populations of CT2 and CT6 transgenic (Tg) cells that develop into pTreg cells in response to different species of endogenously presented Helicobacter antigen. In our comprehensive assessment of multiple intestinal inflammatory models, including infections and physical injury ...


Herpes Zoster Patient Education: A Coloring Book Approach, Sophia Charuhas 2018 Liberty University

Herpes Zoster Patient Education: A Coloring Book Approach, Sophia Charuhas

Senior Honors Theses

Shingles, the disease caused by the herpes zoster virus, is a widespread and widely misunderstood illness in the United States. It is preventable, but many at-risk patients do not know what measures they may take to prevent it. Clear communication from physician to patient is crucial for patient understanding of diseases. Many patient education materials on herpes zoster currently available are often unused. It is therefore beneficial to public health to disseminate new mediums of medical communication, and one way of accomplishing this is through adult coloring books. The pathophysiology of herpes zoster virus is here explored and the idea ...

Allergen Specific Immunotherapy And The Effect On Allergy Induced Asthma, Cord Tanner Landrum 2018 University of North Dakota

Allergen Specific Immunotherapy And The Effect On Allergy Induced Asthma, Cord Tanner Landrum

Physician Assistant Scholarly Project Papers

Allergies are a major public health problem affecting over 300 million people worldwide (Asamoah et. al). An allergic response can occur when a harmless substance, such as tree pollen, is inhaled into the body and mistakenly identified as a harmful substance. Antibodies then bind to the allergen causing a release of chemicals that leads to symptoms such as nasal congestion, runny nose, itchy eyes or skin reactions. For some people, this reaction can also affect the lungs and airways leading to asthma symptoms.

This review analyzes articles from PubMed, Cochran, Clinical Key and references found from UpToDate articles to assess ...


Evaluating The In Vivo Immune Response To Mycobacterium Avium Subspecies Paratuberculosis Infection In Naive And Vaccinated Calves, Tracy Lindquist 2018 Iowa State University

Evaluating The In Vivo Immune Response To Mycobacterium Avium Subspecies Paratuberculosis Infection In Naive And Vaccinated Calves, Tracy Lindquist

Graduate Theses and Dissertations

In these studies, an implant device was developed to detect vaccination-induced, cell-mediated immunity in the subcutaneous tissue of calves. The long-term, future aim of these combined studies is to use the implant device to efficiently screen novel Mycobacterium avium subsp. paratuberculosis (MAP) vaccine candidates. This in vivo screening test would rapidly and inexpensively provide knowledge of a vaccine’s

efficacy in the host species; vaccine candidates exhibiting evidence of efficacy could then be selected for more extensive vaccine challenge studies. A better understanding of in vivo cell-mediated immunity in response to MAP immunization is essential for the development of a ...


Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, Daniel Pollack 2018 CUNY City College

Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, Daniel Pollack

Master's Theses

Thymic epithelial cells (TEC) are essential for a proper adaptive immune response by regulating thymocyte development and establishing central tolerance. In the thymus, TECs differentially express Wnt proteins, which activate canonical and non-canonical Wnt signaling pathways. Wnt signaling is thought to regulate cell survival, proliferation, and development although the direct molecular mechanisms in TECs have yet to be elucidated. The inducible inhibition of canonical Wnt signaling with Dkk1 leads to a rapid loss of TEC progenitors as well as a decline in mature Aire-expressing mTECs. Therefore, we explore the role of Wnt ligands potentially responsible for stimulating and/or regulating ...


Factors That Influence The Formation Of Peanut Allergies In Children, Christie Gleason 2018 University of Central Florida

Factors That Influence The Formation Of Peanut Allergies In Children, Christie Gleason

Honors in the Major Theses

Allergies have the potential to be a life-long debilitating fight, especially the severe reactions from allergies such as anaphylaxis. Peanut allergies tend to be both common and severe, and they happen to be found hiding in many food products. People can have allergic reactions to food products that were made in the same facility as peanut products, that is why it is so important to be aware of the products that are being consumed. The incidence of peanut allergies has increased in the last decade, which is why it is crucial to study these allergies. This thesis looks at when ...


Host Transcriptomic Response To Newcastle Disease Virus In Relatively Resistant And Susceptible Inbred Chicken Lines, Melissa Deist 2018 Iowa State University

Host Transcriptomic Response To Newcastle Disease Virus In Relatively Resistant And Susceptible Inbred Chicken Lines, Melissa Deist

Graduate Theses and Dissertations

Newcastle disease virus (NDV) has devastating impacts on poultry throughout the world. The inbred Fayoumi and Leghorn chicken lines, previously characterized as relatively resistant and susceptible, respectively, to various pathogens were utilized to characterize host response to the NDV vaccine and identify potential genes and pathways associated with NDV resistance. Three-week-old chicks were inoculated with La Sota NDV (challenged) or PBS (nonchallenged) via the oculonasal route. At 2, 6, and 10 days post infection (dpi), approximately one-third of the birds within each line and challenge group were euthanized for tissue collection. At 2 and 6 dpi, lachrymal fluid was collected ...


Investigating Immunological Responses Of Wc1+ Gamma Delta T Cells In Cattle Naturally Infected With Mycobacterium Avium Subspecies Paratuberculosis (Map), Saleh Mohammed Albarrak 2018 Iowa State University

Investigating Immunological Responses Of Wc1+ Gamma Delta T Cells In Cattle Naturally Infected With Mycobacterium Avium Subspecies Paratuberculosis (Map), Saleh Mohammed Albarrak

Graduate Theses and Dissertations

In these studies, we used non-infected cattle and cattle naturally infected with MAP that were either in the subclinical or clinical stage of infection to test the hypothesis that infection status influences WC1+ γδ T cells frequency, proliferation, and cytokine production. We found no significant differences between subclinical and clinical cattle with regard to WC1+ γδ T cells frequency in peripheral blood or in the ileum, a primary site for MAP infection. In PBMCs taken from MAP-infected cattle, WC1+ γδ T cells responded diffrentially to stimulation with PPD-J. In the clinical group, WC1+ γδ T cells failed to proliferate and ...


Gene Therapy Approaches To Immune Tolerance Induction In Canine Hemophilia, Robert French 2018 University of Pennsylvania

Gene Therapy Approaches To Immune Tolerance Induction In Canine Hemophilia, Robert French

Publicly Accessible Penn Dissertations

A key issue in gene therapy is the immune response to the therapeutic transgene. This is especially important in applications where current treatments often elicit an antibody response, like hemophilia, where protein replacement therapy results in neutralizing

antibodies (“inhibitors”) in ~25% of severe hemophilia A and 1-3% of severe hemophilia B patients. To test the ability of skeletal muscle-directed gene therapy to prevent an immune response, we used an inhibitor-prone dog model of severe hemophilia B to express a hyperactive factor IX (FIX) variant from skeletal muscle via adeno-associated viral (AAV) vector and observed curative levels of expression that lasted ...


Immunoglobulin Therapy And Primary Immunodeficient Patients' Health-Related Quality Of Life And Well-Being, Niedre Heckman 2018 Walden University

Immunoglobulin Therapy And Primary Immunodeficient Patients' Health-Related Quality Of Life And Well-Being, Niedre Heckman

Walden Dissertations and Doctoral Studies

Individuals born with primary immune deficiency diseases (PIDD) have a dysfunctional immune system, and many are treated by lifelong injections of immunoglobulin therapy. Studies have shown that these patients have low health-related quality of life (HRQOL) and well-being (WB) and that these outcomes might be improved by the availability of therapy innovated according to preferences for fewer needle sticks or a shorter infusion time. Regulators at the U.S. Food and Drug Administration (FDA) have approved therapies innovated per these preferences. However, there is limited data demonstrating how these innovations impact HRQOL and WB. Using the biopsychosocial model, the purpose ...

Department of Radiation Oncology Faculty Papers

Cancer immunotherapy has transformed the treatment of cancer. However, increasing use of immune-based therapies, including the widely used class of agents known as immune checkpoint inhibitors, has exposed a discrete group of immune-related adverse events (irAEs). Many of these are driven by the same immunologic mechanisms responsible for the drugs' therapeutic effects, namely blockade of inhibitory mechanisms that suppress the immune system and protect body tissues from an unconstrained acute or chronic immune response. Skin, gut, endocrine, lung and musculoskeletal irAEs are relatively common, whereas cardiovascular, hematologic, renal, neurologic and ophthalmologic irAEs occur much less frequently. The majority of irAEs ...
