In counteracting highly infectious and disruptive respiratory diseases such as COVID-19, vaccination remains the primary and safest way to prevent disease, reduce the severity of illness, and save lives. Unfortunately, vaccination is often not the first intervention deployed for a new pandemic, as it takes time to develop and test vaccines, and confirmation of safety requires a period of observation after vaccination to detect potential late-onset vaccine-associated adverse events. In the meantime, nonpharmacologic public health interventions such as mask-wearing and social distancing can provide some degree of protection. As climate change, with its environmental impacts on pathogen evolution and international …

Quality Improvement Initiative To Improve Time And Adherence To Revaccination After Hematopoietic Cell Transplantation: Implementation Of A Revaccination Clinic Within The Transplantation Program, Caitlin Elgarten, Anne Wohlschlaeger, Ellen Levy, Katharine Tadley, Lei Wang, Megan Atkinson, Houston Roberson, Timothy Olson, Nancy Bunin, Jennifer Heimall, Brian Fisher, Stephan Grupp, Jason Freedman

Faculty, Staff and Students Publications

Background:

Revaccination after hematopoietic cell transplantation (HCT) is critical to prevent morbidity and mortality from vaccine preventable illnesses. While earlier re-vaccination after HCT is desirable, they may be ineffective if deployed before partial reconstitution of adaptive immunity. Increasingly, personalized approaches to re-vaccination after HCT have replaced time-based protocols in order to minimize unvaccinated time and enhance vaccine effectiveness. Furthermore, for revaccination to be maximally beneficial, compliance with, and timely delivery of the complete revaccination schedule is imperative, but rare, and there is little data on strategies to optimize vaccine delivery.

Objectives:

The global aim of our quality improvement initiative was …

Human Intestinal Organoids As Models To Study Enteric Bacteria And Viruses, Grace Adeniyi-Ipadeola, Hephzibah Nwanosike, Sasirekha Ramani

Faculty, Staff and Students Publications

Laboratory studies of host-microbe interactions have historically been carried out using transformed cell lines and animal models. Although much has been learned from these models, recent advances in the development of multicellular, physiologically active, human intestinal organoid (HIO) cultures are allowing unprecedented discoveries of host-microbe interactions. Here, we review recent literature using HIOs as models to investigate the pathogenesis of clinically important enteric bacteria and viruses and study commensal intestinal microbes. We also discuss limitations of current HIO culture systems and how technical advances and innovative engineering approaches are providing new directions to improve the model. The studies discussed here …

Structural Biology Of Mcr-1-Mediated Resistance To Polymyxin Antibiotics, Isabel Cristina Materon, Timothy Palzkill

Faculty, Staff and Students Publications

Polymyxins, a last resort antibiotic, target the outer membrane of pathogens and are used to address the increasing prevalence of multidrug-resistant Gram-negative bacteria. The plasmid-encoded enzyme MCR-1 confers polymyxin resistance to bacteria by modifying the outer membrane. Transferable resistance to polymyxins is a major concern; therefore, MCR-1 is an important drug target. In this review, we discuss recent structural and mechanistic aspects of MCR-1 function, its variants and homologs, and how they are relevant to polymyxin resistance. Specifically, we discuss work on polymyxin-mediated disruption of the outer and inner membranes, computational studies on the catalytic mechanism of MCR-1, mutagenesis and …

Modified Vaccine Vectors To Understand Adjuvant Functions Of Listeria During Chronic Schistosomiasis, Stephanie K. Norwood

Biological Sciences Theses & Dissertations

Vaccination is one of the most effective strategies employed to prevent infectious diseases. Successful vaccination is dependent upon the induction of a specific, robust, and prolonged immune response. One of the major challenges faced by vaccine development is vaccine failure due to host-related factors that can modulate the immune system, which leads to non-responsiveness to vaccinations. The generation of new vaccine strategies is imperative to combat these effects. Live bacterial vectors are one approach used as they can elicit humoral immunity, cellular immunity, or both. Listeria monocytogenes is a Gram positive, intracellular pathogen that is an effective bacterial vaccine vector …

Pspa-Mediated Aggregation Protects Streptococcus Pneumoniae Against Desiccation On Fomites, Jessica R. Lane, Muralidhar Tata, Rahena Yasmin, Hansol Im, David E. Briles, Carlos J. Orihuela

APC Fund

Streptococcus pneumoniae (Spn) resides in the nasopharynx where it can disseminate to cause disease. One key Spn virulence factor is pneumococcal surface protein A (PspA), which promotes survival by blocking the antimicrobial peptide lactoferricin. PspA has also been shown to mediate attachment to dying epithelial cells in the lower airway due to its binding of cell surface-bound mammalian (m)GAPDH. Importantly, the role of PspA during colonization is not well understood. Wildtype Spn was present in nasal lavage elutes collected from asymptomatically colonized mice at levels ∼10-fold higher that its isogenic PspA-deficient mutant (ΔpspA). Wildtype Spn also …

Existing Evidence For Influenza B Virus Adaptations To Drive Replication In Humans As The Primary Host, Matthew J. Pekarek, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Influenza B virus (IBV) is one of the two major types of influenza viruses that circulate each year. Unlike influenza A viruses, IBV does not harbor pandemic potential due to its lack of historical circulation in non-human hosts. Many studies and reviews have highlighted important factors for host determination of influenza A viruses. However, much less is known about the factors driving IBV replication in humans. We hypothesize that similar factors influence the host restriction of IBV. Here, we compile and review the current understanding of host factors crucial for the various stages of the IBV viral replication cycle. While …

Antibody Mediated Targeted Drug Delivery System To Improve Immunotherapy In Pancreatic Cancer, Poornima Devi Shaji, Meena Jaggi, Murali M. Yallapu, Subhash C. Chauhan, Sheema Khan

Research Symposium

About 95% of tumor arises from epithelial cell lining ducts known to be pancreatic ductal adenocarcinomas, with less than 5-7% survival rate. Unfortunately, little progress has been seen in the outcomes of patients with PDAC as tumor develops high desmoplasia and chemo-resistance to chemotherapeutic drugs, such as gemcitabine (Gem). Immunotherapy has shown promising results in cancers, except pancreatic cancer due to their characteristic fibrotic tumor microenvironment. The therapies are unable to penetrate to the fibrotic tumors leading to insufficient availability of the therapeutic drugs at the tumor site. A recently identified mucin, MUC13 is aberrantly expressed in pancreatic tumors but …
