Organoid Models For Infectious Disease, Sarah E Blutt, Mary K Estes

Faculty, Staff and Students Publications

Infectious diseases affect individual health and have widespread societal impacts. New ex vivo models are critical to understand pathogenesis, host response, and features necessary to develop preventive and therapeutic treatments. Pluripotent and tissue stem cell-derived organoids provide new tools for the study of human infections. Organoid models recapitulate many characteristics of in vivo disease and are providing new insights into human respiratory, gastrointestinal, and neuronal host-microbe interactions. Increasing culture complexity by adding the stroma, interorgan communication, and the microbiome will improve the use of organoids as models for infection. Organoid cultures provide a platform with the capability to improve human …

Allogeneic transplant (alloHCT) and chimeric antigen receptor modified (CAR)-T cell therapy are potentially cuarative options of diffuse large B-cell lymphoma (DLBCL) relapsing after an autologous (auto)HCT. Although the Center for International Blood and Marrow Transplant Research (CIBMTR) prognostic model can predict outcomes of alloHCT in DLBCL after autoHCT failure, corresponding models of CAR-T treatment in similar patient populations are not available. In this noncomparative registry analysis, we report outcomes of patients with DLBCL (≥18 years) undergoing a reduced intensity alloHCT or CAR-T therapy with axicabtagene ciloleucel during 2012 to 2019 after a prior auto-HCT failure and apply the CIBMTR prognostic …

Nucleoside modified mRNA combined with Acuitas Therapeutics' lipid nanoparticles (LNPs) has been shown to support robust humoral immune responses in many preclinical animal vaccine studies and later in humans with the SARS-CoV-2 vaccination. We recently showed that this platform is highly inflammatory due to the LNPs' ionizable lipid component. The inflammatory property is key to support the development of potent humoral immune responses. However, the mechanism by which this platform drives T follicular helper (Tfh) cells and humoral immune responses remains unknown. Here we show that lack of Langerhans cells or cDC1s neither significantly affected the induction of PR8 HA …

Learning From South Korea’S Covid-19 Response: Why Centralizing The United States Public Health System Is Essential For Future Pandemic Responses, Meghan Ricci

Seattle Journal of Technology, Environmental, & Innovation Law

The COVID-19 pandemic revealed stark differences in governmental preparedness across the globe. The United States, once thought of as a global leader in public health, had the theoretical skill and efficiency to handle the pandemic but failed to utilize those skills and resources during an actual health crisis. In the spring of 2020, everyone watched the U.S.’s reaction to the unfolding of the COVID-19 pandemic due to its historic placeholder as a global leader and innovator. However, the performance of the U.S. in response to the global pandemic disappointed both global commentators and U.S. citizens. This paper will compare the …

Surveillance Of Sars-Cov-2 Rna In Open-Water Sewage Canals Contaminated With Untreated Wastewater In Resource-Constrained Regions, Paramita Basu, Sandeepan Choudhury, Varsha Shridhar, Poorva Huilgol, Samrat Roychoudhury, Indranil Nandi, Angela Chaudhuri, Arindam Mitra

Touro College of Pharmacy (New York) Publications and Research

Sewage-based surveillance for COVID-19 has been described in multiple countries and multiple settings. However, nearly all are based on testing sewage treatment plant inflows and outflows using structured sewage networks and treatment systems. Many resource-limited countries worldwide have open canals, lakes and other such waste-contaminated water bodies that act as a means of sewage effluent discharge. These could serve as hyperlocal testing points for detecting COVID-19 incidence using the effluents from nearby communities. However, a sensitive, robust and economical method of SARS-CoV-2 RNA detection from open waste contaminated water bodies in resource-constrained regions is currently lacking. A protocol employed in …

Harnessing Mycobacterium Bovis Bcg Trained Immunity To Control Human And Bovine Babesiosis, Reginaldo G. Bastos, Heba F. Alzan, Vignesh A. Rathinasamy, Brian M. Cooke, Odir A. Dellagostin, Raul G. Barletta, Carlos E. Suarez

School of Veterinary and Biomedical Sciences: Faculty Publications

Babesiosis is a disease caused by tickborne hemoprotozoan apicomplexan parasites of the genus Babesia that negatively impacts public health and food security worldwide. Development of effective and sustainable vaccines against babesiosis is currently hindered in part by the absence of definitive host correlates of protection. Despite that, studies in Babesia microti and Babesia bovis, major causative agents of human and bovine babesiosis, respectively, suggest that early activation of innate immune responses is crucial for vertebrates to survive acute infection. Trained immunity (TI) is defined as the development of memory in vertebrate innate immune cells, allowing more efficient responses to subsequent …

The Allergy Mediator Histamine Confers Resistance To Immunotherapy In Cancer Patients Via Activation Of The Macrophage Histamine Receptor H1, Hongzhong Li, Yi Xiao, Qin Li, Jun Yao, Xiangliang Yuan, Yuan Zhang, Xuedong Yin, Yohei Saito, Huihui Fan, Ping Li, Wen-Ling Kuo, Angela Halpin, Don L Gibbons, Hideo Yagita, Zhongming Zhao, Da Pang, Guosheng Ren, Cassian Yee, J Jack Lee, Dihua Yu

Reinvigoration of antitumor immunity remains an unmet challenge. Our retrospective analyses revealed that cancer patients who took antihistamines during immunotherapy treatment had significantly improved survival. We uncovered that histamine and histamine receptor H1 (HRH1) are frequently increased in the tumor microenvironment and induce T cell dysfunction. Mechanistically, HRH1-activated macrophages polarize toward an M2-like immunosuppressive phenotype with increased expression of the immune checkpoint VISTA, rendering T cells dysfunctional. HRH1 knockout or antihistamine treatment reverted macrophage immunosuppression, revitalized T cell cytotoxic function, and restored immunotherapy response. Allergy, via the histamine-HRH1 axis, facilitated tumor growth and induced immunotherapy resistance in mice and humans. …

A Retrospective Analysis Of Ebola Virus Disease In Liberia, Matthew Jeremiah Matson

Theses, Dissertations and Capstones

The outbreak of Ebola virus disease (EVD) centered in the West African countries of Guinea, Liberia, and Sierra Leone from 2013-2016 was the longest and largest such outbreak on record. At least 30,000 cases were reported, and the outbreak lasted nearly two-and-a-half years. Despite the progress made during and since that time, many questions remain unanswered. The studies here utilize a large set of nearly 750 whole blood samples from patients that were triaged and treated at the ELWA-3 Ebola treatment unit in Monrovia, Liberia in 2014 and 2015. Viral load, as approximated by qRT-PCR diagnostic assays in the field, …

Type I Ifn Signaling Protects Mice From Lethal Sars-Cov-2 Neuroinvasion., Md Bashir Uddin, Yuejin Liang, Shengjun Shao, Sunil Palani, Michael Mckelvey, Scott C. Weaver, Keer Sun

Journal Articles: Pathology and Microbiology

Multiple organ damage is common in patients with severe COVID-19, even though the underlying pathogenic mechanisms remain unclear. Acute viral infection typically activates type I IFN (IFN-I) signaling. The antiviral role of IFN-I is well characterized in vitro. However, our understanding of how IFN-I regulates host immune response to SARS-CoV-2 infection in vivo is incomplete. Using a human ACE2-transgenic mouse model, we show in the present study that IFN-I receptor signaling is essential for protection against the acute lethality of SARS-CoV-2 in mice. Interestingly, although IFN-I signaling limits viral replication in the lung, the primary infection site, it is dispensable …

Previous studies have found that arginine biosynthesis in Staphylococcus aureus is repressed via carbon catabolite repression (CcpA), and proline is used as a precursor. Unexpectedly, however, robust growth of S. aureus is not observed in complete defined medium lacking both glucose and arginine (CDM-R). Mutants able to grow on agar-containing defined medium lacking arginine (CDM-R) were selected and found to contain mutations within ahrC, encoding the canonical arginine biosynthesis pathway repressor (AhrC), or single nucleotide polymorphisms (SNPs) upstream of the native arginine deiminase (ADI) operon arcA1B1D1C1. Reverse transcription-PCR (RT-PCR) studies found that mutations within ccpA or ahrC or …

Improved Database Filtering Technology Enables More Efficient Ab Initio Design Of Potent Peptides Against Ebola Viruses, Thomas Ripperda, Yangsheng Yu, Atul Verma, Elizabeth Klug, Michellie Thurman, St. Patrick Reid, Guangshun Wang

Journal Articles: Pathology and Microbiology

The rapid mutations of viruses such as SARS-CoV-2 require vaccine updates and the development of novel antiviral drugs. This article presents an improved database filtering technology for a more effective design of novel antiviral agents. Different from the previous approach, where the most probable parameters were obtained stepwise from the antimicrobial peptide database, we found it possible to accelerate the design process by deriving multiple parameters in a single step during the peptide amino acid analysis. The resulting peptide DFTavP1 displays the ability to inhibit Ebola virus. A deviation from the most probable peptide parameters reduces antiviral activity. The designed …

Simple Summary: Myocarditis is the inflammation of the heart muscle, and viral infections are a common cause of this disease. Myocarditis in some patients can progress to dilated cardiomyopathy (DCM). The mouse model of coxsackievirus B3 (CVB3) is commonly used to understand this disease progression in DCM patients. In this paper, we have attempted to analyze antibodies for heart antigens that could be produced as a result of heart damage in animals infected with CVB3 using a technique called Phage ImmunoPrecipitation Sequencing (PhIP-Seq). The analyses led us to identify antibodies for several proteins that were not previously reported that may …
