Analysis Of Humira, Electro-Acupuncture, And Pulsatile Dry Cupping On Reducing Joint Inflammation In Patients With Rheumatoid Arthritis, Natalie Noll
AUCTUS: The Journal of Undergraduate Research and Creative Scholarship
Humira, an anti-TNF drug aimed at decreasing inflammation in Rheumatoid Arthritis patients, can cause skin diseases from rashes to skin cancer. Humira works by blocking the chemical receptor RANKL which inhibits the production of osteoclasts. Osteoclasts are cells that attack and eat bone and cartilage therefore an inhibitory mechanism would cause inflammation.. By analyzing Humira’s effect on the human body, Humira can be compared to other treatments such as electro-acupuncture and pulsatile dry cupping to determine the viability of these alternative treatment methods in regards to their abilities to decrease inflammation in Rheumatoid Arthritis patients through blocking RANKL. An analysis …

The objective of this work was to design conjugates of anti-HIV nucleosides conjugated with fatty acids and cell-penetrating poly-L-arginine (polyArg) peptides. Three conjugates of polyArg cell-penetrating peptides with fatty acyl derivatives of alovudine (FLT), lamivudine (3TC), and emtricitabine (FTC) were synthesized. In general, the compounds exhibited anti-HIV activity against X4 and R5 cell-free virus with EC50 values of 1.5–16.6 μM. FLT-CO-(CH2)12-CO-(Arg)7 exhibited EC50 values of 2.9 μM and 3.1 μM against X4 and R5 cell-free virus, respectively. The FLT conjugate was selected for further preformulation studies by determination of solution state degradation and lipid solubility. The compound was found to …
The Effects Of Vitamin D Supplementation On Influenza, Jonah M. Spoerndle
The Effects Of Vitamin D Supplementation On Influenza, Jonah M. Spoerndle
Williams Honors College, Honors Research Projects
Recently the role of vitamin D in other non-classical capacities has been evaluated. One of these non-classical vitamin D roles is assisting in maintaining proper immune system health. One disease that has a great effect on the immune system is influenza. Vitamin D helps to prevent and limit influenza by moderating the inflammatory cytokines as well as promoting the production of monocytes that help destroy the invading materials. Through the use of vitamin D supplementation the recommended daily amount of vitamin D can be assured and optimal health could be achieved. The purpose of this project was to design a …

The immune system of H. sapiens has innate signaling pathways that arose in ancestral species. This is exemplified by the discovery of the Toll-like receptor (TLR) pathway using free-living model organisms such as Drosophila melanogaster. The TLR pathway is ubiquitous and controls sensitivity to pathogen-associated molecular patterns (PAMPs) in eukaryotes. There is, however, a marked absence of this pathway from the plathyhelminthes, with the exception of the Pellino protein family, which is present in a number of species from this phylum. Helminth Pellino proteins are conserved having high similarity, both at the sequence and predicted structural protein level, with that …
Autoimmune Susceptibility Imposed By Public Tcrβ Chains, Yunqian Zhao
Autoimmune Susceptibility Imposed By Public Tcrβ Chains, Yunqian Zhao
Theses and Dissertations (ETD)
The major histocompatibility complex (MHC) is the strongest genetic risk factor for autoimmunity. It acts together with a corresponding TCR repertoire, yet, considering the extent of the repertoire's diversity, how this imposes disease susceptibility on a population is not well understood. We address the hypothesis that shared or public TCR, those present in most individuals, modulate autoimmune risk. High resolution analyses of autoimmune encephalomyelitis-associated T-cell receptor β chain (TCRβ) showed preferential utilization of public TCR sequences, implicating them in pathogenesis. Disease-associated public TCRβ, when transgenically expressed in association with endogenously rearranged T-cell receptor α chain (TCRα), could further endow unprimed …

Smarter Vaccine Design Will Circumvent Regulatory T Cell-Mediated Evasion In Chronic Hiv And Hcv Infection, Leonard Moise, Frances Terry, Andres H. Gutierrez, Ryan Tassone, Phyllis Losikoff, Stephen H. Gregory, Chris Bailey-Kellogg
Dartmouth Scholarship
Despite years of research, vaccines against HIV and HCV are not yet available, due largely to effective viral immunoevasive mechanisms. A novel escape mechanism observed in viruses that cause chronic infection is suppression of viral-specific effector CD4(+) and CD8(+) T cells by stimulating regulatory T cells (Tregs) educated on host sequences during tolerance induction. Viral class II MHC epitopes that share a T cell receptor (TCR)-face with host epitopes may activate Tregs capable of suppressing protective responses. We designed an immunoinformatic algorithm, JanusMatrix, to identify such epitopes and discovered that among human-host viruses, chronic viruses appear more human-like than viruses …
Myasthenia Gravis: A Closer Look, Erin L. Ricker
Myasthenia Gravis: A Closer Look, Erin L. Ricker
Nursing Student Class Projects (Formerly MSN)
Myasthenia gravis (MG) is a rare, chronic autoimmune disease that affects the neurotransmitter acetylcholine and the acetylcholine receptors at the neuromuscular junction (Mestecky, 2013). MG causes fluctuating skeletal muscle weakness and fatigue. According to the Myasthenia Gravis Foundation of America (MGFA) (2010), 20 per 100,000 patients are diagnosed with MG, although researchers believe several more patients are misdiagnosed or missed entirely. Several neurological disorders have similar clinical presentations to MG making it difficult for inexperienced practitioners to identify and properly diagnose patients. Patients are often misdiagnosed and delayed proper treatment for one to two years after initial presentation of symptoms …
Global Burden Of Tuberculosis, Diana Moses
Global Burden Of Tuberculosis, Diana Moses
Nursing Student Class Projects (Formerly MSN)
Tuberculosis (TB) is a major health concern not only in the United States, but in the entire world. TB is an airborne communicable infection which has affected human beings from immemorial times, evidenced by TB being found in the skeletal remains of ancient mummies (Gough & Kaufman, 2011). There are many patho physiological events in TB that concern the entire body, especially the respiratory and immunological systems. According to Knechel, TB prevalence is rising due to the increased number of patients infected with HIV, bacterial resistance to medications, increased international travel and immigration from countries with high prevalence of TB, …
Steven-Johnson’S Syndrome/Toxic Epidermal Necrolysis, Lindsey Grant
Steven-Johnson’S Syndrome/Toxic Epidermal Necrolysis, Lindsey Grant
Nursing Student Class Projects (Formerly MSN)
Steven-Johnson’s Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are both diseases mediated by hypersensitive immune reactions resulting in “full thickness epidermal necrosis” characterized by skin detachment. However, in SJS, there is only 10% skin surface area involvement whereas in TEN, over 30% of the skin becomes detached. TENS has a 50% mortality rate. (East-Innis & Thompson, 2013, p. 590) Why Chosen: SJS/TEN is a rare but extremely fatal disease. Initially, it is often mistaken as a simple allergic reaction to a new medication or environmental exposure because both cause truncal rashes and fevers. However, simple allergic reactions occur within days …

Type I IFNs play an important role in innate and adaptive immunity against viral infections. A novel type I IFN, namely IFN-ε, which can protect against vaginal transmission of HSV2 and Chlamydia muridarum bacterial infection, has been described in mice and humans. Nevertheless, the principle cell type and the expression pattern of IFN-ε in tissues remain uncertain. In addition, the expression of IFN-ε in Indian rhesus macaques (Macaca mulatta) has not been reported. Here, we analyzed IFN-ε expression in multiple mucosal sites of uninfected or SIV-infected Indian rhesus macaques using IHCS. We report for the first time the …
Fty720 (Fingolimod) Provides Insight Into The Molecular Mechanisms Of Multiple Sclerosis, Madelyn Elizabeth Crawford
Fty720 (Fingolimod) Provides Insight Into The Molecular Mechanisms Of Multiple Sclerosis, Madelyn Elizabeth Crawford
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
Multiple sclerosis (MS) is a neurodegenerative disorder caused by a prolonged immune- mediated inflammatory response that targets myelin. Nearly all of the drugs approved for the treatment of MS are general immunosuppressants or only function in symptom management. The oral medication fingolimod, however, is reported to have direct therapeutic effects on cells of the central nervous system in addition to immunomodulatory functions. Fingolimod is known to interact with sphingosine-1-phosphate (S1P) receptors, and the most widely- accepted theory for its mechanism of action is functional antagonism of the receptor. This review examines significant neuromodulatory effects achieved by functional antagonism of the …
Analysis Of The Role Of Astrocyte Elevated Gene-1 In Normal Liver Physiology And In The Onset And Progression Of Hepatocellular Carcinoma, Chadia L. Robertson
Analysis Of The Role Of Astrocyte Elevated Gene-1 In Normal Liver Physiology And In The Onset And Progression Of Hepatocellular Carcinoma, Chadia L. Robertson
Theses and Dissertations
First identified over a decade ago, Astrocyte Elevated Gene-1 (AEG-1) has been studied extensively due to early reports of its overexpression in various cancer cell lines. Research groups all over the globe including our own have since identified AEG-1 overexpression in cancers of diverse lineages including cancers of the liver, colon, skin, prostate, breast, lung, esophagus, neurons and neuronal glia as compared to matched normal tissue. A comprehensive and convincing body of data currently points to AEG-1 as an essential component, critical to the progression and perhaps onset of cancer. AEG-1 is a potent activator of multiple pro-tumorigenic signal transduction …

Faculty Publications & Research of the TUC College of Osteopathic Medicine
CASPASE-12 (CASP12) has a downregulatory function during infection and thus may protect against inflammatory disease. We investigated the distribution of CASP12 alleles (#rs497116) in African-Americans (AA) with rheumatoid arthritis (RA). CASP12 alleles were genotyped in 953 RA patients and 342 controls. Statistical analyses comparing genotype groups were performed using Kruskal–Wallis non-parametric ANOVA with Mann–Whitney U tests and chi-square tests. There was no significant difference in the overall distribution of CASP12 genotypes within AA with RA, but CASP12 homozygous patients had lower baseline joint-narrowing scores. CASP12 homozygosity appears to be a subtle protective factor for some aspects of RA in AA …

Electronic Theses and Dissertations
The yeasts Pichia pastoris and Kluyveromyces lactis were used to express several recombinant human proteins for further biochemical characterization. Two substitution variants of recombinant human enteropeptidase light chain (rhEPL) were engineered to modify the extended substrate specificity of this serine protease. Both were secreted as active enzymes in excess of 1.7 mg/L in P. pastoris fermentation broth. The substitution variant rhEPL R96Q showed significantly reduced specificities for the preferred substrate sequences DDDDK and DDDDR; however, the rhEPL Y174R variant displayed improved specificities for these substrate sequences relative to all other reported variants of this enzyme. The neutrophil serine proteases human …

T-Cell Treatments For Solid And Hematological Tumors, Drew C. Deniger
Dissertations and Theses (Open Access)
Cell-based therapies have demonstrated potency and efficacy as cancer treatment modalities. T cells can be dichotomized by their T cell receptor (TCR) complexes where alpha/beta T cells (95% of T cells) and gamma/delta T cells (+T cells proliferated to clinically significant numbers and ROR1+ tumor cells were effectively targeted and killed by both ROR1-specific CAR+ T cell populations, although ROR1RCD137 were superior to ROR1RCD28 in clearance of leukemia xenografts in vivo. The second specific aim focused on generating bi-specific CD19-specific CAR+ gamma/delta T cells with polyclonal TCRgamma/delta repertoire on CD19+ artificial antigen presenting cells (aAPC). …

Stimulation Through Tlr4 Increases Fviii Inhibitor Formation In A Mouse Model Of Hemophilia A, Claire K. Holley
Stimulation Through Tlr4 Increases Fviii Inhibitor Formation In A Mouse Model Of Hemophilia A, Claire K. Holley
Dissertations and Theses (Open Access)
Hemophilia A is a clotting disorder caused by functional factor VIII (FVIII) deficiency. About 25% of patients treated with therapeutic recombinant FVIII develop antibodies (inhibitors) that render subsequent FVIII treatments ineffective. The immune mechanisms of inhibitor formation are not entirely understood, but circumstantial evidence indicates a role for increased inflammatory response, possibly via stimulation of Toll-like receptors (TLRs), at the time of FVIII immunization. I hypothesized that stimulation through TLR4 in conjunction with FVIII treatments would increase the formation of FVIII inhibitors. To test this hypothesis, FVIII K.O. mice were injected with recombinant human FVIII with or without concomitant doses …

Graduate School of Biomedical Sciences Theses and Dissertations
Pathogenic Th17 cells drive progression of many autoimmune diseases. Th17 cells develop from naïve T cells in the immune system after antigen-driven stimulation in a specific cytokine environment. Normally, T cells act to fight off infection, but when not properly controlled, they can cause disease. The cytokine interleukin-23 (IL-23) plays an essential role in the expansion of pathogenic Th17 cells. IL-23 is a heterodimeric protein, composed of a p19 alpha chain and a p40 beta chain. The p40 is also part of IL-12 and binds to the IL-12 receptor beta 1 (IL-12Rβ1) subunit. Thus, it follows that the IL-23 receptor …

Factors That Lead To The Immunotherapy Gap In Multiple Sclerosis Testing, Karthika Solai
AUCTUS: The Journal of Undergraduate Research and Creative Scholarship
Multiple sclerosis is a disease that affects the central nervous system. Most doctors and scientists believe that it is an autoimmune disease. Simply put, the immune system attacks the nerves in a person’s body, thereby causing myelin damage, inflammation, and neurodegeneration. The plaque that then builds up on the nerves is scar tissue created when the wounds made by the immune system heal. It is this plaque that inhibits communication between the axons in the body and causes the symptoms of MS, which includes problems with movement, pain, vision problems, trouble swallowing, fatigue, and heat sensitivity (Baker et al., 2011, …

Three nucleoside analogues, 3′-fluoro-2′,3′-dideoxythymidine (FLT), 3′-azido-2′,3′-dideoxythymidine (AZT), and 2′,3′-dideoxy-3′-thiacytidine (3TC) were conjugated with three different dicarboxylic acids to afford the long chain dicarboxylate esters of nucleosides. In general, dinucleoside ester conjugates of FLT and 3TC with long chain dicarboxylic acids exhibited higher anti-HIV activity than their parent nucleosides. Dodecanoate and tetradecanoate dinucleoside ester derivatives of FLT were found to be the most potent compounds with EC50 values of 0.8–1.0 nM and 3–4 nM against HIV-1US/92/727 and HIV-1IIIB cells, respectively. The anti-HIV activity of the 3TC conjugates containing long chain dicarboxylate diester (EC50 = 3–60 nM) was improved by 1.5–66 fold …

Autoimmune Consequences Of Histone Deimination During Neutrophil Activation, Nishant Dwivedi
Autoimmune Consequences Of Histone Deimination During Neutrophil Activation, Nishant Dwivedi
Theses and Dissertations (ETD)
Tolerance blocks the expression of autoantibodies, whereas autoimmunity promotes it. How tolerance breaks and autoantibody production begins, thus, are crucial questions for the understanding and treatment of autoimmune diseases. Evidence implicates cell death and autoantigen modifications in the initiation of autoimmune reactions. One form of neutrophil cell death deserves attention because it occurs as a consequence of neutrophil activation, requires the post-translational modification of histones and results in the extracellular release of chromatin. The extracellular chromatin incorporates histones in which arginines have been converted to citrullines by peptidylarginine deiminase IV (PAD4) creating structures that capture or "trap" bacterial pathogens. Neutrophil …

Despite the success of potent reverse transcriptase (RT) inhibitors against human immunodeficiency virus type 1 (HIV-1) in combination regimens, the development of drug resistant RTs constitutes a major hurdle for the long-term efficacy of current antiretroviral therapy. Nucleoside β-triphosphate analogs of adenosine and nucleoside reverse transcriptase inhibitors (NRTIs) (3′-azido-2′,3′-dideoxythymidine (AZT), 3′-fluoro-2′,3′-dideoxythymidine (FLT), and 2′,3′-didehydro-2′,3′-dideoxythymidine (d4T)) were synthesized and their inhibitory activities were evaluated against wild-type and multidrug resistant HIV-1 RTs. Adenosine β-triphosphate (1) and AZT β-triphosphate (2) completely inhibited the DNA polymerase activity of wild type, the NRTI multi resistant, and nonnucleoside RT inhibitors (NNRTI) resistant HIV-1 RT at 10 …

A series of two classes of 3-phenylpyrazolopyrimidine-1,2,3-triazole conjugates were synthesized using click chemistry approach. All compounds were evaluated for inhibition of Src kinase and human ovarian adenocarcinoma (SK-Ov-3), breast carcinoma (MDA-MB-361), and colon adenocarcinoma (HT-29). Hexyl triazolyl-substituted 3-phenylpyrazolopyrimidine exhibited inhibition of Src kinase with an IC50 value of 5.6 µM. 4-Methoxyphenyl triazolyl-substituted 3-phenylpyrazolopyrimidine inhibited the cell proliferation of HT-29 and SK-Ov-3 by 73% and 58%, respectively, at a concentration of 50 µM.
Immune Recognition Of Self Nucleic Acids Driven By Endogenous Antimicrobial Peptides: Role In Autoimmunity, Dipyaman Ganguly
Immune Recognition Of Self Nucleic Acids Driven By Endogenous Antimicrobial Peptides: Role In Autoimmunity, Dipyaman Ganguly
Dissertations and Theses (Open Access)
Innate immune recognition of extracellular host-derived self-DNA and self-RNA is prevented by endosomal seclusion of the Toll-like receptors (TLRs) in the dendritic cells (DCs). However, in psoriasis plasmacytoid dendritic cells have been found to be able to sense self-DNA molecules in complex with the endogenous cationic antimicrobial peptide LL37, which are internalized into the endosomal compartments and thus can access TLR9. We investigated whether this endogenous peptide can also interact with extracellular self-RNA and lead to DC activation. We found that LL37 binds self-RNA as well as self-DNA going into an electrostatic interaction; forms micro-aggregates of nano-scale particles protected from …

An Epitope From Acanthamoeba Castellanii That Cross-React With Proteolipid Protein 139-151-Reactive T Cells Induces Autoimmune Encephalomyelitis In Sjl Mice, Chandirasegaran Massilamany, David Steffan, Jay Reddy
Jay Reddy Publications
We report here that an epitope (aa, 83-95) derived from Acanthamoeba castellanii (ACA) induces clinical signs of experimental autoimmune encephalomyelitis (EAE) in SJL/J mice reminiscent of the disease induced with myelin proteolipid protein (PLP) 139-151. By using IAs/tetramers, we demonstrate that both ACA 83-95 and PLP 139-151 generate antigen-specific cross-reactive CD4 T cells and the T cells secrete identical patterns of cytokines and induce EAE with a similar severity. These results may provide insights into the pathogenesis of multiple sclerosis and ACA-induced granulomatous encephalitis.
