Alpha-1 antitrypsin deficiency is a monogenic disorder resulting in emphysema due principally to the unopposed effects of neutrophil elastase. We previously reported achieving plasma wild-type alpha-1 antitrypsin concentrations at 2.5%-3.8% of the purported therapeutic level at 1 year after a single intramuscular administration of recombinant adeno-associated virus serotype 1 alpha-1 antitrypsin vector in alpha-1 antitrypsin deficient patients. We analyzed blood and muscle for alpha-1 antitrypsin expression and immune cell response. We also assayed previously reported markers of neutrophil function known to be altered in alpha-1 antitrypsin deficient patients. Here, we report sustained expression at 2.0%-2 ...

Elucidating The Role Of Interleukin-17a In West Nile Virus Infection, Dhiraj Acharya 2017 University of Southern Mississippi

Elucidating The Role Of Interleukin-17a In West Nile Virus Infection, Dhiraj Acharya

Dissertations

West Nile virus (WNV) is a neurotropic flavivirus of significant public health importance for which no therapeutics and vaccine are currently available. Interleukin-17A (IL-17A) is an inflammatory cytokine that regulates diverse immune functions, while its role is unclear in host’s immune response to WNV. Furthermore, CD8+ T cells are crucial components of immunity and play a vital role in recovery from WNV infection. Here, we report a previously unrecognized function of IL-17A in regulating CD8+ T cell cytotoxicity. We show that WNV induces the expression of IL-17A in both mouse splenocytes and human peripheral blood mononuclear cells cultured in ...


Sickle Cell Anemia: Current Treatments And Potential Advancements, Vanessa Martinez 2017 Southeastern University - Lakeland

Sickle Cell Anemia: Current Treatments And Potential Advancements, Vanessa Martinez

Selected Honors Theses

Sickle cell anemia is a disease that affects red blood cells, specifically the hemoglobin protein. An amino acid mutation in the gene that encodes β-globin leads to malformation of the β subunit of hemoglobin.3, Valine becomes glutamic acid in the mutated β-globin gene.9 The mutation malformation leads to the red blood cells becoming sickle shaped, or crescent shaped.3,4 The sickle shape of red blood cells in individuals with sickle cell disease leads to vaso-occlusive crisis.9 Vaso-occlusive crisis includes complications such as blood clotting, chronic pain, organ failure, organ death, and possibly early mortality.9 The ...

The Antiviral Rna Interference Response Provides Resistance To Lethal Arbovirus Infection And Vertical Transmission In Caenorhabditis Elegans, Don B. Gammon, Takao Ishidate, Lichao Li, Weifeng Gu, Neal S. Silverman, Craig C. Mello 2017 University of Massachusetts Medical School

The Antiviral Rna Interference Response Provides Resistance To Lethal Arbovirus Infection And Vertical Transmission In Caenorhabditis Elegans, Don B. Gammon, Takao Ishidate, Lichao Li, Weifeng Gu, Neal S. Silverman, Craig C. Mello

University of Massachusetts Medical School Faculty Publications

The recent discovery of the positive-sense single-stranded RNA (ssRNA) Orsay virus (OV) as a natural pathogen of the nematode Caenorhabditis elegans has stimulated interest in exploring virus-nematode interactions. However, OV infection is restricted to a small number of intestinal cells, even in nematodes defective in their antiviral RNA interference (RNAi) response, and is neither lethal nor vertically transmitted. Using a fluorescent reporter strain of the negative-sense ssRNA vesicular stomatitis virus (VSV), we show that microinjection of VSV particles leads to a dose-dependent, muscle tissue-tropic, lethal infection in C. elegans. Furthermore, we find nematodes deficient for components of the antiviral RNAi ...

Pediatrics Faculty Publications

BACKGROUND: We evaluated the impact of the 2011 Pediatric Infectious Diseases Society/Infectious Diseases Society of America pneumonia guideline and hospital-level implementation efforts on antibiotic prescribing for children hospitalized with pneumonia.

METHODS: We assessed inpatient antibiotic prescribing for pneumonia at 28 children's hospitals between August 2009 and March 2015. Each hospital was also surveyed regarding local implementation efforts targeting antibiotic prescribing and organizational readiness to adopt guideline recommendations. To estimate guideline impact, we used segmented linear regression to compare the proportion of children receiving penicillins in March 2015 with the expected proportion at this same time point had the ...

Open Access Articles

Antibodies raised in Indian rhesus macaques [Macaca mulatta (MM)] in many preclinical vaccine studies are often evaluated in vitro for titer, antigen-recognition breadth, neutralization potency, and/or effector function, and in vivo for potential associations with protection. However, despite reliance on this key animal model in translation of promising candidate vaccines for evaluation in first in man studies, little is known about the properties of MM immunoglobulin G (IgG) subclasses and how they may compare to human IgG subclasses. Here, we evaluate the binding of MM IgG1, IgG2, IgG3, and IgG4 to human Fc gamma receptors (FcgammaR) and their ability ...


Immunotherapeutic Strategies To Reverse Tumor Associated Immunosuppression In Breast Cancer, Sruthi Ravindranathan 2016 University of Arkansas, Fayetteville

Immunotherapeutic Strategies To Reverse Tumor Associated Immunosuppression In Breast Cancer, Sruthi Ravindranathan

Theses and Dissertations

Heterogenous cancers such as breast carcinoma, would highly benefit from personalized vaccine approaches such as autologous tumor cell vaccines (ATCVs). By using cancer cells that are isolated from self, this approach has the potential to generate a polyclonal immune response against tumor antigens, that are specific to the individual. However, so far, ATCVs against breast cancers have not had any clinical success due to the poor immunogenicity of the malignant cells.

In this study, for the first time, we determined tumor derived G-CSF to play a major role in affecting immune response against breast cancer ATCVs. By using CRISPR/Cas9 ...


The Role Of Late Antigen In Cd4 Memory T Cell Formation During Influena [I.E. Influenza] Infection: A Dissertation, Bianca L. Bautista 2016 University of Massachusetts Medical School

The Role Of Late Antigen In Cd4 Memory T Cell Formation During Influena [I.E. Influenza] Infection: A Dissertation, Bianca L. Bautista

GSBS Dissertations and Theses

While memory CD4 T cells are critical for effective immunity to pathogens, the mechanisms underlying their generation are poorly defined. Although extensive work has been done to examine the role of antigen (Ag) in shaping memory formation, most studies focus on the requirements during the first few days of the response known as the priming phase. Little is known about whether or not Ag re-encounter by effector T cells (late Ag) alters CD4 memory T cell formation. Since influenza infection produces a large, heterogeneous, protective CD4 memory T cell population, I used this model to examine the role of late ...


Fc Receptor-Mediated Activities Of Env-Specific Monoclonal Antibodies Generated From Human Volunteers Receiving A Dna Prime-Protein Boost Hiv Vaccine: A Dissertation, Matthew R. Costa 2016 University of Massachusetts Medical School

Fc Receptor-Mediated Activities Of Env-Specific Monoclonal Antibodies Generated From Human Volunteers Receiving A Dna Prime-Protein Boost Hiv Vaccine: A Dissertation, Matthew R. Costa

GSBS Dissertations and Theses

Human immunodeficiency type 1 (HIV-1) is able to elicit broadly potent neutralizing antibodies in a very small subset of individuals only after several years’ infection and as a result, vaccines that elicit these types of antibodies have been difficult to design. The RV144 trial showed that a moderate protection is possible, which may correlate with antibody dependent cellular cytotoxicity (ADCC) activity. Previous studies in the Lu lab demonstrated that in an HIV-1 vaccine phase I trial, DP6-001, a polyvalent Env DNA prime-protein boost formulation, could elicit potent and broadly reactive, gp120-specific antibodies with positive neutralization activities along with multiple Fc ...

Open Access Articles

The most widespread Plasmodium species, Plasmodium vivax, poses a significant public health threat. An effective vaccine is needed to reduce global malaria burden. Of the erythrocytic stage vaccine candidates, the 19 kDa fragment of the P. vivax Merozoite Surface Protein 1 (PvMSP119) is one of the most promising. Our group has previously defined several promiscuous T helper epitopes within the PvMSP1 protein, with features that allow them to bind multiple MHC class II alleles. We describe here a P. vivax recombinant modular chimera based on MSP1 (PvRMC-MSP1) that includes defined T cell epitopes genetically fused to PvMSP119. This vaccine candidate ...

The outcome of Mycobacterium tuberculosis infection and the immunological response to the bacillus Calmette-Guerin (BCG) vaccine are highly variable in humans. Deciphering the relative importance of host genetics, environment, and vaccine preparation for the efficacy of BCG has proven difficult in natural populations. We developed a model system that captures the breadth of immunological responses observed in outbred individual mice, which can be used to understand the contribution of host genetics to vaccine efficacy. This system employs a panel of highly diverse inbred mouse strains, consisting of the founders and recombinant progeny of the "Collaborative Cross" project. Unlike natural populations ...

Programmed cell death ligand 1 (PD-L1) is a cell surface glycoprotein that regulates the cellular immune response and serves as a targetable immune checkpoint molecule. PD-L1 is expressed on tumor cells and the immune microenvironment of several human malignancies, including a subset of aggressive lymphomas. We sought to investigate further the clinical and pathologic features of EBV-negative diffuse large B-cell lymphoma (DLBCL) cases that express PD-L1. Immunohistochemical staining using an anti-PD-L1 monoclonal antibody was performed on DLBCL cases from 86 patients. These patients received standard chemotherapy treatment and were followed for up to 175 months. Overall, 14 cases (16%) were ...


A Model To Explain How The Bacille Calmette Guerin (Bcg) Vaccine Drives Interleukin-12 Production In Neonates, Chido Loveness Kathivu, Daniel H. Libraty 2016 University of Massachusetts Medical School

A Model To Explain How The Bacille Calmette Guerin (Bcg) Vaccine Drives Interleukin-12 Production In Neonates, Chido Loveness Kathivu, Daniel H. Libraty

Open Access Articles

The Bacille Calmette Guerin (BCG) vaccine is the only routine vaccination at birth that effectively induces neonatal T-helper 1 (Th1)-polarized immune responses. The primary cytokine that drives CD4+ T-cell Th1 differentiation is interleukin (IL)-12 p70, a heterodimeric cytokine composed of the IL-12 p35 and IL-12 p40 subunits. We therefore examined the mechanisms involved in BCG vaccine stimulation of IL-12 p35 and p40 production from human umbilical cord (neonatal) cells. We found that BCG bacilli did not upregulate IL-12 p35 mRNA production, but upregulated IL-12 p40 mRNA production in a Toll-like receptor (TLR)2-dependent manner, in human neonatal monocyte-derived ...

Memory Cd8+ T Cell Function During Mycobacterium Tuberculosis Infection: A Dissertation, Stephen M. Carpenter 2016 University of Massachusetts Medical School

Memory Cd8+ T Cell Function During Mycobacterium Tuberculosis Infection: A Dissertation, Stephen M. Carpenter

GSBS Dissertations and Theses

T cell vaccines against Mycobacterium tuberculosis (Mtb) and other pathogens are based on the principle that memory T cells rapidly generate effector responses upon challenge, leading to pathogen clearance. Despite eliciting a robust memory CD8+ T cell response to the immunodominant Mtb antigen TB10.4 (EsxH), we find the increased frequency of TB10.4-specific CD8+ T cells conferred by vaccination to be short-lived after Mtb challenge. To compare memory and naïve CD8+ T cell function during their response to Mtb, we track their expansions using TB10.4-specific retrogenic CD8+ T cells. We find that the primary (naïve) response outnumbers the ...
