Toward The Development Of A Pan-Lyssavirus Vaccine, Sabrine Ben Hamed, Jacob Myers, Anisha Chandwani, Christoph Wirblich, Drishya Kurup, Nir Paran, Matthias Schnell

Department of Microbiology and Immunology Faculty Papers

In addition to the rabies virus (RABV), 16 more lyssavirus species have been identified worldwide, causing a disease similar to RABV. Non-rabies-related human deaths have been described, but the number of cases is unknown, and the potential of such lyssaviruses causing human disease is unpredictable. The current rabies vaccine does not protect against divergent lyssaviruses such as Mokola virus (MOKV) or Lagos bat virus (LBV). Thus, a more broad pan-lyssavirus vaccine is needed. Here, we evaluate a novel lyssavirus vaccine with an attenuated RABV vector harboring a chimeric RABV glycoprotein (G) in which the antigenic site I of MOKV replaces …

School of Dentistry Faculty Publications

Candida albicans and Staphylococcus aureus are two commonly associated pathogens that cause nosocomial infections with high morbidity and mortality. Our prior and current work using a murine model of polymicrobial intra-abdominal infection (IAI) demonstrates that synergistic lethality is driven by Candida-induced upregulation of functional S. aureus α-toxin leading to polymicrobial sepsis and organ damage. In order to determine the candidal effector(s) mediating enhanced virulence, an unbiased screen of C. albicans transcription factor mutants was undertaken revealing that zcf13Δ/Δ fails to drive augmented α-toxin or lethal synergism during co-infection. A combination of transcriptional and phenotypic profiling approaches shows that ZCF13 regulates …

Multiple myeloma (MM) is a hematologic malignancy characterized by uncontrolled proliferation of plasma cells in the bone marrow. MM patients with aggressive progression have poor survival, emphasizing the urgent need for identifying new therapeutic targets. Here, we show that the leukocyte immunoglobulin-like receptor B1 (LILRB1), a transmembrane receptor conducting negative immune response, is a top-ranked gene associated with poor prognosis in MM patients. LILRB1 deficiency inhibits MM progression in vivo by enhancing the ferroptosis of MM cells. Mechanistic studies reveal that LILRB1 forms a complex with the low-density lipoprotein receptor (LDLR) and LDLR adapter protein 1 (LDLRAP1) to facilitate LDL/cholesterol …

The formation of multinucleated syncytiotrophoblast (STB) through cell fusion of cytotrophoblast, also termed syncytialization, ensures the proper placental structure and functions. Nutrient insufficiency and inactivation of the mechanistic target of rapamycin complex 1 (mTORC1) in trophoblasts have been shown to enhance STB formation; however, the underlying mechanism remains elusive. Here, we showed that the deficiency of a mTORC1 downstream transcriptional factor, TFEB, significantly impaired STB formation in human trophoblasts and knock-out mice. TFEB conferred direct transcriptional activation of the fusogen ERVFRD-1 and thereby promoted trophoblast syncytialization. Additionally, TFEB expression positively correlated with the reinforced trophoblast syncytialization in human fetal growth …

Understanding and treating human diseases require valid animal models. Leveraging the genetic diversity in rhesus macaque populations across eight primate centers in the United States, we conduct targeted-sequencing on 1845 individuals for 374 genes linked to inherited human retinal and neurodevelopmental diseases. We identify over 47,000 single nucleotide variants, a substantial proportion of which are shared with human populations. By combining rhesus and human allele frequencies with established variant prediction methods, we develop a machine learning-based score that outperforms established methods in predicting missense variant pathogenicity. Remarkably, we find a marked number of loss-of-function variants and putative deleterious variants, which …

Antitumor Effects Of Resveratrol Opposing Mechanisms Of Helicobacter Pylori In Gastric Cancer, Daniela Trautmann, Francesca Suazo, Keila Torres, Layla Simón

Faculty, Staff and Student Publications

Gastric cancer is an aggressive and multifactorial disease. Helicobacter pylori (H. pylori) is identified as a significant etiological factor in gastric cancer. Although only a fraction of patients infected with H. pylori progresses to gastric cancer, bacterial infection is critical in the pathology and development of this malignancy. The pathogenic mechanisms of this bacterium involve the disruption of the gastric epithelial barrier and the induction of chronic inflammation, oxidative stress, angiogenesis and metastasis. Adherence molecules, virulence (CagA and VacA) and colonization (urease) factors are important in its pathogenicity. On the other hand, resveratrol is a natural polyphenol with …

A 63-year-old male developed a mycotic pseudoaneurysm (MPA) two months after a renal transplant at the anastomotic site. He presented with uncontrolled hypertension and elevated creatinine. The pseudoaneurysm occurred at the anastomosis between the two donor renal arteries and the left external iliac artery. We describe a unique surgical reconstruction where the MPA was resected and the vasculature was reconstructed using deceased donor vessels. A deceased donor common iliac artery including superior gluteal and inferior gluteal branches were used as a jump graft from the contralateral common iliac artery to the two transplanted renal arteries. The external iliac artery was …

Sump Syndrome: The Forgotten Cause Of Painless Jaundice In The Elderly, Mark Ayoub, Amna Anees

Journal of Community Hospital Internal Medicine Perspectives

Painless jaundice is a common presentation of abdominal malignancy seen in elderly patients. While malignancy may be a common cause of obstructive jaundice in that population group, anchor bias should always be avoided. We present a case of an elderly woman who presented with painless jaundice and weight loss. She had a very remote history of cholecystitis. She was found to have Sump syndrome due to a stricture at the Choledochoduodenostomy (CDD) site. She underwent endoscopic retrograde cholangiopancreatography (ERCP) with stent placement which shortly led to resolution of her jaundice. Biopsy from the stricture site came back negative for malignancy.

Triticale As A Source Of Resistance To Wheat Streak Mosaic Virus And Triticum Mosaic Virus, Marcos Winicius Goncalves De Souza

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Wheat streak mosaic virus (WSMV) and Triticum mosaic virus (TriMV) present a great threat to wheat production in the Great Plains area of the United States due to the loss of photosynthetic area causing reductions in crop yields. Effective control of these viruses is limited to a few available strategies including controlling volunteer wheat and using currently identified resistant genes to both the vector and viruses. While effective, these genes show temperature sensitivity and yield drag, and evidence that the vectors and viruses can overcome them has been found. Thus, new methods of genetic resistance are urgently needed. Field observations …

Development Of A Durable And Low-Dose Universal Vaccine Against Swine Influenza A Virus, Erika Petro-Turnquist

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Swine Influenza A Virus (IAV-S) imposes a significant burden on the pork industry and poses a great threat to public health due to its zoonotic potential. Susceptibility to human, avian, and swine influenza make pigs the ultimate mixing vessels for reassorted influenza A virus strains. Current vaccination strategies induce short-lived and strain-specific responses against IAV-S. Further, the substantial genetic diversity of IAV-S necessitates consistent revaccination and updating of commercial vaccines. Computational platforms have recently emerged as a promising strategy to develop new-age vaccines against infectious diseases in livestock animals. Here, we describe a computationally derived set of vaccine immunogens, called …
