Coronaviruses are a family of RNA viruses that cause acute and chronic diseases of the upper and lower respiratory tract in humans and other animals. SARS-CoV-2 is a recently emerged coronavirus that has led to a global pandemic causing a severe respiratory disease known as COVID-19 with significant morbidity and mortality worldwide. The development of antiviral therapeutics are urgently needed while vaccine programs roll out worldwide. Here we describe a diamidobenzimidazole compound, diABZI-4, that activates STING and is highly effective in limiting SARS-CoV-2 replication in cells and animals. diABZI-4 inhibited SARS-CoV-2 replication in lung epithelial cells. Administration of diABZI-4 intranasally ...

CULTURE & CRISIS: Reconciling Constitutionalism & Federalism in a Time of Crisis

The purpose of this paper is to delve further into the topic of Culture & Crisis: Reconciling Constitutionalism & Federalism in a Time of Crisis through Liberty University’s Helms School of Government & Journal of Statesmanship & Public Policy. The United States of America is currently under siege by the COVID-19 virus. This virus has steadily killed hundreds of individuals and consequently nearly shutdown the American socio-economic system. Through a constitutional government and federal principles, the executive functions have been able to address this time of crisis. However, there are different views referencing exactly how to address the needs of our nation during this time of crisis. This threat to public health is perceived differently by the Republican and Democratic parties. Democrats have been viewed as trying to present the severity of the situation, in terms of health, finances, and safety. The Republicans are viewed as presenting information that does not demonstrate such a severity of the situation; however, they do understand the perceived threats which have invoked several governmental functions (e.g., relief funds, unemployment insurance). These views can be skewed, as Republicans and Democrats, as they live in different counties which have been impacted differently by the COVID-19 virus. Tensions have been on the rise due to this phenomenon which can be handled efficiently through the execution of deliberative constitutionalism. These issues and more will be discussed further.


Sodium Pyruvate Ameliorates Influenza A Virus Infection In Vitro And In Vivo, Jessica M. Reel 2021 Missouri State University

Sodium Pyruvate Ameliorates Influenza A Virus Infection In Vitro And In Vivo, Jessica M. Reel

MSU Graduate Theses

Pyruvate is produced in duplicate at the end of glycolysis in addition to ATP and NADH. Pyruvate is the metabolite of choice in most cells, whether obtained exogenously or endogenously. Recently we found that the addition of pyruvate’s conjugate base, sodium pyruvate, to cell culture media dampened the immune response to influenza A virus (IAV) infection in cultured innate immune cells. Thus, I decided to investigate the mechanism and potential for treatment of IAV. In vitro using bone marrow derived macrophages that were infected with IAV we found that adding sodium pyruvate to the media decreased immune signaling pathways ...


The Role Of Cd4 T Cell Help In Effective Cd8 T Cell Responses During Mycobacterium Tuberculosis Infection, Yu-Jung Lu 2021 University of Massachusetts Medical School

The Role Of Cd4 T Cell Help In Effective Cd8 T Cell Responses During Mycobacterium Tuberculosis Infection, Yu-Jung Lu

GSBS Dissertations and Theses

Tuberculosis (TB), a transmissible disease caused by Mycobacterium tuberculosis (Mtb), is a global health threat. To design an effective vaccine, we need to better understand how different elements of our immune system collaborate to fight against Mtb. CD4 T cells are crucial in protective immunity to Mtb because they produce cytokines including interferon-γ. In contrast, CD8 T cells are thought to play a modest role. Whether CD4 T cells act as “helper” cells to promote optimal CD8 T cell responses during TB is unknown. We argue CD8 T cells’ role are likely underestimated because CD8 T cell functions are compromised ...

B16: Chikungunya Virus Time Course Infection Of Human Macrophages, Madison Gray, Israel Guerrero-Arguero, Antonio Solis Leal, Richard Robison, Brad Burges, Brett Pickett

Annual Research Symposium

Chikungunya virus (CHIKV) is an Alphavirus spread by Aedes spp. mosquitoes and is responsible for infecting 1.1 million people per year worldwide, including a large epidemic in the western hemisphere in 2014-2015. During the body’s immune response to CHIKV, human macrophages become infected after phagocytosis of CHIKV and undergo induced apoptosis, catalyzing the virus spread in the body. It is presently unclear what macrophage genes, functions, and intracellular signaling pathways are impacted during the early, intermediate, and late stages of CHIKV infection. Therefore we quantified the transcriptional response of human macrophage cells infected with CHIKV at two different ...

P6: Predictors Of Compliance With Covid-19 Related Non- Pharmaceutical Interventions Amongst University Students, Spencer G. Shumway, Ethan R. Tolman, Jonas D. Hopper, David Patterson, Gabriella Hubble, Jamie L. Jensen Dr.

Annual Research Symposium

College campuses have been an area where the novel coronavirus has spread rapidly, thus this study is focused on compliance with COVID-19 related non-pharmaceutical interventions among college students.
We surveyed over 600 college students from across the United States and modeled predictors of compliance with non-pharmaceutical interventions. To determine how applicable nationwide modeling might be to individual local campuses we also administered this same survey to nearly 600 students at two large universities in Utah County (Brigham Young University and Utah Valley University). We then ran structural equation modeling (SEM) to determine what factors are related to student compliance with ...


Effectiveness Of Pathogen-Specific Passive Antibodies To Mitigate Infectious Diseases In Apis Mellifera, Tanner Nordseth 2021 University of South Dakota

Effectiveness Of Pathogen-Specific Passive Antibodies To Mitigate Infectious Diseases In Apis Mellifera, Tanner Nordseth

Honors Thesis

Honeybees (Apis mellifera) are widely recognized as a vital part of the global ecosystem and the world's food supply due to their pivotal role in the pollination of both natural and agricultural flora. Colony Collapse Disorder (CCD) is an emerging phenomenon characterized by a colony's worker bees deserting the hive and leaving the queen behind. This usually results in colony failure. CCD is a multifactorial issue, with many environmental stressors and pathogens playing a role. Deformed Wing Virus (DWV) has been identified as a leading cause in this phenomenon. Paenibacillus larvae (P. larvae) is another lethal pathogen that ...

COVID-19 Publications by UMMS Authors

SARS-CoV-2 has rapidly become a global pandemic. In addition to the acute pulmonary symptoms of COVID-19 (the disease associated with SARS-CoV-2 infection), pulmonary and distal coagulopathies have caused morbidity and mortality in many patients. Currently, the molecular pathogenesis underlying COVID-19 associated coagulopathies are unknown. Identifying the molecular basis of how SARS-CoV-2 drives coagulation is essential to mitigating short and long term thrombotic risks of sick and recovered COVID-19 patients. We aimed to perform coagulation focused transcriptome analysis of in vitro infected primary respiratory epithelial cells, patient derived bronchial alveolar lavage (BALF) cells, and circulating immune cells during SARS-CoV-2 infection. Our ...

The antiviral properties of broadly neutralizing antibodies against HIV are well-documented but no vaccine is currently able to elicit protective titers of these responses in primates. While current vaccine modalities can readily induce non-neutralizing antibodies against simian immunodeficiency virus (SIV) and HIV, the ability of these responses to restrict lentivirus transmission and replication remains controversial. Here, we investigated the antiviral properties of non-neutralizing antibodies in a group of Indian rhesus macaques (RMs) that were vaccinated with vif, rev, tat, nef, and env, as part of a previous study conducted by our group. These animals manifested rapid and durable control of ...

H1n1 Influenza Virus (Swine Flu): A Comprehensive Insight Into Escalating Catch-22 Scenarios, Muhammad Shahzaib, Ehsan Ul Haq

The University of Louisville Journal of Respiratory Infections

Introduction: Viruses have always been a major cause of various disastrous pandemics in mankind’s history. H1N1 became a threat when its original strain was first discovered back in the swine flu pandemic of 2009. It became highly catastrophic on a large scale because none of the therapeutic interventions and methodologies that were already present at the time were effective against the virus.

Methods: A vast amount of literature and research is available regarding H1N1 influenza from different reputable sources online. The data was gathered following the contrasting and relative situations of 1918 as well as the 2009 pandemic in ...

Antibodies elicited in response to infection undergo somatic mutation in germinal centers that can result in higher affinity for the cognate antigen. To determine the effects of somatic mutation on the properties of SARS-CoV-2 spike receptor-binding domain (RBD)-specific antibodies, we analyzed six independent antibody lineages. As well as increased neutralization potency, antibody evolution changed pathways for acquisition of resistance and, in some cases, restricted the range of neutralization escape options. For some antibodies, maturation apparently imposed a requirement for multiple spike mutations to enable escape. For certain antibody lineages, maturation enabled neutralization of circulating SARS-CoV-2 variants of concern and ...

Cnbp, Rel, And Bhlhe40 Variants Are Associated With Il-12 And Il-10 Responses And Tuberculosis Risk [Preprint], Javeed A. Shah, Christopher M. Sassetti, Katherine A. Fitzgerald

University of Massachusetts Medical School Faculty Publications

Rationale: The major human genes regulating M. tuberculosis (Mtb)-induced immune responses and tuberculosis (TB) susceptibility are poorly understood. Although IL-12 and IL-10 are critical for TB pathogenesis, the genetic factors that regulate their expression are unknown. CNBP, REL, and BHLHE40 are master regulators of IL-12 and IL-10 signaling.

Objectives: To determine whether common human genetic variation in CNBP, REL and BHLHE40 is associated with IL-12 and IL-10 expression, adaptive immune responses to mycobacteria, and susceptibility to TB.

Methods and Main Measurements: We characterized the association between common variants in CNBP, REL, and BHLHE40 and innate immune responses in dendritic ...

Disseminated infection with the high virulence strain of Mycobacterium avium 25291 lead to progressive thymic atrophy. We previously uncovered that M. avium-induced thymic atrophy is due to increased levels of glucocorticoids synergizing with nitric oxide (NO) produced by interferon gamma (IFNγ) activated macrophages. Where and how these mediators are playing, was yet to be understood. We hypothesized that IFNγ and NO might be affecting bone marrow (BM) T cell precursors and/or T cell differentiation in the thymus. We show that M. avium infection causes a reduction on the percentage of lymphoid-primed multipotent progenitors (LMPP) and common lymphoid progenitors ...

Cd4 T Cell Help Prevents Cd8 T Cell Exhaustion And Promotes Control Of Mycobacterium Tuberculosis Infection [Preprint], Yu-Jung Lu, Palmira Barreira-Silva, Shayla Boyce, Jennifer Powers, Kelly Cavallo, Samuel M. Behar

University of Massachusetts Medical School Faculty Publications

CD4 T cells are essential for immunity to tuberculosis because they produce cytokines including interferon-γ. Whether CD4 T cells act as “helper” cells to promote optimal CD8 T cell responses during Mycobacterium tuberculosis is unknown. Using two independent models, we show that CD4 T cell help enhances CD8 effector functions and prevents CD8 T cell exhaustion. We demonstrate synergy between CD4 and CD8 T cells in promoting the survival of infected mice. Purified helped, but not helpless, CD8 T cells efficiently restrict intracellular bacterial growth in vitro. Thus, CD4 T cell help plays an essential role in generating protective CD8 ...

A Novel Dna And Protein Combination Covid-19 Vaccine Formulation Provides Full Protection Against Sars-Cov-2 In Rhesus Macaques, Yuzhong Li, Guangnan Hu, Shixia Wang, Qihan Li, Shan Lu, Wei Cun

COVID-19 Publications by UMMS Authors

The current study aims to develop a safe and highly immunogenic COVID-19 vaccine. The novel combination of a DNA vaccine encoding the full-length Spike (S) protein of SARS-CoV-2 and a recombinant S1 protein vaccine induced high level neutralizing antibody and T cell immune responses in both small and large animal models. More significantly, the co-delivery of DNA and protein components at the same time elicited full protection against intratracheal challenge of SARS-CoV-2 viruses in immunized rhesus macaques. As both DNA and protein vaccines have been proven safe in previous human studies, and DNA vaccines are capable of eliciting germinal center ...
