Autoantibodies To The Ny-Eso-1 Tumor Antigen In Metastatic Melanoma: Sialylation Of The Fc Region Of Immunoglobulin G Induces Differential Expression Signatures Of Inflammatory Molecules During Dendritic Cell Differentiation And Maturation, Martin Oaks, Nathaniel Rein, John O. Richards, James Shaffer

Journal of Patient-Centered Research and Reviews

Purpose: We tested the hypothesis that different glycoforms of antibodies from patients with metastatic melanoma have different functional effects on human dendritic cell differentiation and maturation.

Methods: Antibodies to the cancer antigen NY-ESO-1 were affinity-purified from patients with melanoma and further fractionated into different glycoforms by lectin chromatography. Sialic acid-rich and sialic acid-poor fractions of these immunoglobulin G antibodies (IgG) were added to dendritic cell cultures during both differentiation and maturation, and the resulting cellular messenger RNA (mRNA) and culture supernatants were tested by microarray and enzyme-linked immunoassay for molecules related to inflammatory pathways.

Results: We identified unique mRNA and ...

Discovery Of A 240 Million Year Old Nematode Parasite Egg In A Cynodont Coprolite Sheds Light On The Early Origin Of Pinworms In Vertebrates, Jean-Pierre Hugot, Scott Gardner, Victor Borba, Priscilla Araujo, Daniela Leles, Átila Da-Rosa, Juliana Dutra, Luis Fernando Ferreira, Adauto Araújo

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

Background: We report the discovery of a nematode parasite egg (Nemata: Oxyurida) from a coprolite closely associated with the remains of several species of Cynodontia, dated to 240 million years old. This finding is particularly significant because this is the oldest record of an oxyurid nematode yet discovered, and because the cynodonts are considered a stem-group of the mammals.

Methods: We extracted material from a fully mineralized coprolite by both scraping the surface, and removing fragments from its interior with clean dental instruments used a single time. A single drop of glycerol from a new vial was added as a ...

Avian Influenza Virus Prevalence In Migratory Waterfowl In The United States, 2007-2009, Scott R. Groepper Mr., Thomas Deliberto, Mark Vrtiska, Kerri Pedersen, Seth Swafford, Scott Hyngstrom

Scott R Groepper

SUMMARY. We analyzed 155,535 samples collected for surveillance of avian influenza viruses (AIVs), in the United States from 2007 to 2009, from migratory waterfowl (ducks, geese, and swans). The goal was to elucidate patterns of prevalence by flyway and functional groups to determine targets for future surveillance. Apparent prevalence of AIV was highest in the Pacific Flyway in 2007–2008 (14.2% and 14.1%, respectively), in the Mississippi Flyway in 2009 (16.8%), and lowest each year in the Atlantic Flyway (range, 7.3%–8.9%). Dabbling ducks had higher apparent prevalence of AIV (12.8%–18.8 ...


Transcription Of Inflammatory Genes: Long Noncoding Rna And Beyond, Susan Carpenter, Katherine A. Fitzgerald 2014 University of Massachusetts Medical School

Transcription Of Inflammatory Genes: Long Noncoding Rna And Beyond, Susan Carpenter, Katherine A. Fitzgerald

Infectious Diseases and Immunology Publications and Presentations

The innate immune system must coordinate elaborate signaling pathways to turn on expression of hundreds of genes to provide protection against pathogens and resolve acute inflammation. Multiple genes within distinct functional categories are coordinately and temporally regulated by transcriptional on and off switches in response to distinct external stimuli. Three classes of transcription factors act together with transcriptional coregulators and chromatin-modifying complexes to control these programs. In addition, newer studies implicate long noncoding RNA (lncRNA) as additional regulators of these responses. LncRNAs promote, fine-tune, and restrain the inflammatory program. In this study, we provide an overview of gene regulation and ...

Transmitted by the tsetse fly, Trypanosoma brucei is a protozoan parasite that causes sleeping sickness in human and nagana in cattle. While infecting the bloodstream and central nervous system, T. brucei evades the immune system by altering its major surface antigen, Variant Surface Glycoproteins (VSGs), which forms a thick coat on its cell membrane. The expression sites for VSGs are at the sub-telomeric regions of T. brucei chromosomes. Telomeres, DNA-protein complexes located at the end of chromosomes, provide chromosome stability by preventing degradation of the chromosome ends. The telomere complex also regulates the sub-telomeric VSG expression and switching in T ...


Understanding Recurrent Disease: A Dynamical Systems Approach, Wenjing Zhang 2014 Western University

Understanding Recurrent Disease: A Dynamical Systems Approach, Wenjing Zhang

University of Western Ontario - Electronic Thesis and Dissertation Repository

Recurrent disease, characterized by repeated alternations between acute relapse and long re- mission, can be a feature of both common diseases, like ear infections, and serious chronic diseases, such as HIV infection or multiple sclerosis. Due to their poorly understood etiology and the resultant challenge for medical treatment and patient management, recurrent diseases attract much attention in clinical research and biomathematics. Previous studies of recurrence by biomathematicians mainly focus on in-host models and generate recurrent patterns by in- corporating forcing functions or stochastic elements. In this study, we investigate deterministic in-host models through the qualitative analysis of dynamical systems, to ...


The Hunt For Protective Correlates Of Immunity To Plasmodium Falciparum Malaria, Ann M. Moormann, V. Ann Stewart 2014 University of Massachusetts Medical School

The Hunt For Protective Correlates Of Immunity To Plasmodium Falciparum Malaria, Ann M. Moormann, V. Ann Stewart

Open Access Articles

Determining an immunologic correlate of protection against Plasmodium falciparum malaria has been the holy grail of natural infection studies, and sought after as an endpoint for malaria vaccine trials. An in vitro assay that provides an accurate and precise assessment of protective immunity to malaria would make smaller, short-duration studies feasible, rather than the currently powered study designs that use morbidity or mortality as outcomes. Such a biomarker would be especially desirable in situations where malaria control measures that result in decreases in clinical endpoints and putatively waning protective immunity have been implemented. In an article published in BMC Medicine ...


Transcriptional Regulation Of Peptidylarginine Deiminase Type Iv: Implications For Rheumatoid Arthritis, Ali Abbas 2014 Western University

Transcriptional Regulation Of Peptidylarginine Deiminase Type Iv: Implications For Rheumatoid Arthritis, Ali Abbas

University of Western Ontario - Electronic Thesis and Dissertation Repository

High titers of anti-citrullinated protein antibodies have been detected in sera of rheumatoid arthritis (RA) patients, implicating citrullinating enzymes in the pathogenesis of RA. Peptidylarginine deiminase type IV (PAD4) is a member of the PAD family of enzymes that catalyze the post- translational modification of arginine to citrulline and has been linked with RA. However, little is known about its transcriptional regulation. Therefore, our aim was to determine how transcription of PAD4 is activated in the myeloid lineage. Using bioinformatics, a potential nuclear factor kappa B (NF-kB) binding site was identified on the PAD4 promoter. Luciferase assays were used to ...

Background: The IL-1 family of cytokines is known to play an important role in inflammation therefore understanding the mechanism by which they are produced is paramount. Despite the recent plethora of publications dedicated to the study of these cytokines, the mechanism by which they are produced in the airway following endotoxin, Lipopolysaccharide (LPS), exposure is currently unclear. The aim was to determine the mechanism by which the IL-1 cytokines are produced after LPS inhaled challenge.

Methods:Mice were challenged with aerosolised LPS, and lung tissue and bronchiolar lavage fluid (BALF) collected. Targets were measured at the mRNA and protein level ...

STEM Teacher and Researcher (STAR) Program Posters

Chronic wounds are defined as an injury that does not heal in a predictable pattern or time frame. The healing process is composed of specific stages and chronic wounds have been interrupted in one or more stages of this process. This project focuses on the bacterial component of an infected wound, specifically on the catecholamines influencing the bacteria in the wound site. The assay developed in this experiment is designed to optimally grow bacteria in a simulated eukaryotic wound environment, and evaluate biofilm expression and catecholamine production of the bacteria. Bacteria used in this study are Staphylococcus aureus and Pseudomonas ...

Potential Roles Of Peroxidases In Caenorhabditis Elegans Innate Immunity, George R. Tiller, George R. Tiller

UT GSBS Dissertations and Theses (Open Access)

The production of ROS (reactive oxygen species) in response to pathogen detection is a rapid, nonspecific response that is evolutionarily conserved from nematodes to humans. ROS serve as direct and indirect effectors of innate and adaptive immunity. In Caenorhabditis elegans, a ROS burst is observed during infection and is mediated by the dual oxidase BLI-3, which produces H2O2. RNAi (RNA interference) to reduce the amount of BLI-3 results in a significant increase in susceptibility to pathogens, suggesting BLI-3 has a role in the immune response. However, H2O2 by itself is not a potent antimicrobial ...


The Role Of The C5a Receptor In Host Defense Against Listeria Monocytogenes, Daniel Calame 2014 Texas Medical Center Library

The Role Of The C5a Receptor In Host Defense Against Listeria Monocytogenes, Daniel Calame

UT GSBS Dissertations and Theses (Open Access)

Listeria monocytogenes (Lm) is a major cause of mortality resulting from food poisoning in the United States. While the complement component C5 is known to be protective in listeriosis, it is unknown how its cleavage fragment C5a participates. Here we show in a model of systemic Lm infection that the C5a receptor is essential for host defense. C5aR-/- mice have reduced survival and increased bacterial burden in the liver and spleen in comparison to WT mice. Surprisingly, C5aR-/- mice also have a dramatic reduction in splenocyte numbers resulting from elevated cell death as indicated by TUNEL staining and caspase 3 ...

Bartonella bacilliformis is the bacterial agent of Carrión's disease and is presumed to be transmitted between humans by phlebotomine sand flies. Carrión's disease is endemic to high-altitude valleys of the South American Andes, and the first reported outbreak (1871) resulted in over 4,000 casualties. Since then, numerous outbreaks have been documented in endemic regions, and over the last two decades, outbreaks have occurred at atypical elevations, strongly suggesting that the area of endemicity is expanding. Approximately 1.7 million South Americans are estimated to be at risk in an area covering roughly 145,000 km2 of Ecuador ...

It was a time when, in the nation's schools, drills for nuclear war were as frequent as fire drills- when Americans and their Soviet counterparts lived with a constant fear of imminent worldwide destruction. "You had a cultural mindset that was apocalyptic," said Robert S. Weisbrot, Christian A. Johnson Distinguished Teaching Professor of History at Colby, "that believed you could not guarantee that your wonderful suburban home and family and community...would survive ten more seconds."

"It was not simply a matter of two countries that are adversaries building up weapons," said Weisbrot. "Each saw the other as the ...

The oomycete genus Aquastella is described to accommodate two new species of parasites of rotifers observed in Brooktrout Lake, New York State, USA. Three rotifer species – Keratella taurocephala,Polyarthra vulgaris, and Ploesoma truncatum – were infected, and this is the first report of oomycete infection in these species. Aquastella attenuata was specific to K. taurocephala and Aquastella aciculariswas specific to P. vulgaris and P. truncatum. The occurrence of infections correlated with peak host population densities and rotifers were infected in the upper layers of the water column. Sequencing of 18S rRNA and phylogenetic analysis of both species placed them within ...
