The HIV-1 fusion peptide (FP) represents a promising vaccine target, but global FP sequence diversity among circulating strains has limited anti-FP antibodies to ~60% neutralization breadth. Here we evolve the FP-targeting antibody VRC34.01 in vitro to enhance FP-neutralization using site saturation mutagenesis and yeast display. Successive rounds of directed evolution by iterative selection of antibodies for binding to resistant HIV-1 strains establish a variant, VRC34.01_mm28, as a best-in-class antibody with 10-fold enhanced potency compared to the template antibody and ~80% breadth on a cross-clade 208-strain neutralization panel. Structural analyses demonstrate that the improved paratope expands the FP binding groove to …

Bovine respiratory disease (BRD) is a leading cause of disease in feedlot and stocker calves with Mannheimia haemolytica (MH) as one of the most common etiologies. One of the most effective means of controlling BRD is through metaphylaxis, which involves administering antimicrobials to all animals at high risk of developing BRD. However, increasing prevalence of multidrug resistant (MDR) MH may reduce efficacy of metaphylaxis due to decreased susceptibility to drugs used for metaphylaxis. Primarily, this study aimed to determine the effect of tulathromycin metaphylaxis and subsequent BRD treatment on antimicrobial resistance (AMR) in MH isolated from stocker calves. Secondary objectives …

Highly pathogenic avian influenza viruses (HPAIVs) of subtype H5 of the Gs/GD/96 lineage remain a major threat to poultry due to endemicity in wild birds. H5N1 HPAIVs from this lineage were detected in 2021 in the United States (US) and since then have infected many wild and domestic birds. We evaluated the pathobiology of an early US H5N1 HPAIV (clade 2.3.4.4b, 2021) and two H5N8 HPAIVs from previous outbreaks in the US (clade 2.3.4.4c, 2014) and Europe (clade 2.3.4.4b, 2016) in chickens and turkeys. Differences in clinical signs, mean death times (MDTs), and virus transmissibility were found between chickens and …

Traditional cellular and live-virus methods for detection of SARS-CoV-2 neutralizing antibodies (nAbs) are labor- and time-intensive, and thus not suited for routine use in the clinical lab to predict vaccine efficacy and natural immune protection. Here, we report the development and validation of a rapid, high throughput method for measuring SARS-CoV-2 nAbs against native-like trimeric spike proteins. This assay uses a blockade of human angiotensin converting enzyme 2 (hACE-2) binding (BoAb) approach in an automated digital immunoassay on the Quanterix HD-X platform. BoAb assays using Wuhan-WT (vaccine strain), delta (B.1.167.2), omicron BA1 and BA2 variant viral strains showed strong correlation …

Role Of The Glutamine-Polyamine-Hypusine Axis In Cd8+ T Cell Fate And Function, Aya Gamal Aly Sadek Elmarsafawi

USF Tampa Graduate Theses and Dissertations

T cells are critical effectors of the immune response against pathogens and malignancies and, given the recent success of T-cell immunotherapies in cancer, there is now an urgent need to enhance the efficacy and durability of T-cell immune responses to improve anti-tumor immunity. Formation of memory T cells is a critical step of a successful immune response as it ensures maintenance of long-term immunity and protection from re-exposure to foreign antigens. Notably, metabolism regulates the fate and function of T cells and is a powerful tool to modulate T-cell activity and memory differentiation. Accordingly, metabolic interventions to augment T-cell memory …

Investigations Of Emerging Zoonotic And Vector-Borne Viruses At The Juncture Of Environmental, Human, And Animal Health, Erik A. Turner

LSU Doctoral Dissertations

Reemerging and emerging zoonotic viruses are some of the most important public and One Health threats facing the world. Understanding the transmission dynamics of these viruses is vital to reducing the disease burden, and one of the key aspects to these transmission systems is the environmental vertex of the One Health triangle. SARS-CoV-2 has only recently emerged as a global public health threat, and within 4 years, over 700 million cases have been reported. As a novel pathogen, many aspects of transmission, including environmental fomite transmission and disinfection, were initially a glaring gap in knowledge. Additionally, while chikungunya virus (CHIKV) …

Tumor microbiota can produce active metabolites that affect cancer and immune cell signaling, metabolism, and proliferation. Here, we explore tumor and gut microbiome features that affect chemoradiation response in patients with cervical cancer using a combined approach of deep microbiome sequencing, targeted bacterial culture, and in vitro assays. We identify that an obligate L-lactate-producing lactic acid bacterium found in tumors, Lactobacillus iners, is associated with decreased survival in patients, induces chemotherapy and radiation resistance in cervical cancer cells, and leads to metabolic rewiring, or alterations in multiple metabolic pathways, in tumors. Genomically similar L-lactate-producing lactic acid bacteria commensal to other …

Center for Brain, Biology, and Behavior: Faculty Publications

Background Latina mothers have been especially affected by the pandemic and historically exhibit high rates of depression and anxiety. However, few longitudinal studies have assessed the effect of the pandemic on this vulnerable population. We hypothesized that COVID-19-related stressors would associate with psychological distress among Latina mothers across the first year of the pandemic.

Methods We investigated COVID-19-related impact, stigma, and fears across two critical time points and changes in these measures in relation to changes in maternal anxiety and depression among mothers of Mexican descent living in Southern California (n=152). Surveys were administered within 5–16 weeks of …

Nebraska Center for Virology: Faculty Publications

African swine fever virus (ASFV) is circulating in many swine-producing countries, causing significant economic losses. It is observed that pigs experimentally vaccinated with a live-attenuated virus (LAV) but not a killed virus (KV) vaccine develop solid homologous protective immunity. The objective of this study was to comparatively analyze antibody profiles between pigs vaccinated with an LAV vaccine and those vaccinated with a KV vaccine to identify potential markers of vaccineinduced protection. Thirty ASFV seronegative pigs were divided into three groups: Group 1 received a single dose of an experimental LAV, Group 2 received two doses of an experimental KV vaccine, …

Intraspecific Variation Of Morphological Traits Backed Up With Molecular Evidence Votes For Re‑Appraisal Of Hitherto Distinguished Balaustium Species—A Case Study Of Balaustium Murorum (Acariformes: Parasitengona, Erythraeidae), Joanna Mąkol, Magdalena Felska

Harold W. Manter Laboratory of Parasitology: Library Materials

Molecular examination of representatives of Balaustium from several populations in SW Poland, performed using the sequence data from the mitochondrial cytochrome c oxidase subunit I, confirmed their common specific affiliation and identity with Balaustium murorum. The potential presence of distinct species in the studied material, preliminarily inferred from the discovery of clusters as a result of Principal Component Analysis exploring the metric data sets, was rejected due to the finding of only one haplotype, at intra- and inter-population sampling. An insight into meristic traits in larvae, focused on chaetotaxy of legs, revealed wider variation than hitherto recognized for the …

Clinical, imaging, and microbiological data were evaluated by multidisciplinary adjudication teams. The primary outcome of interest was grade ≥2 (CTCAEv5) pneumonitis. Clinicopathologic variables, tobacco use, cancer therapies, and preexisting lung disease were assessed for univariate effects using Cox proportional hazards models. We created multivariate Cox proportional hazards models to assess risk factors for …

Individual And Population Age Impact Social Behavior And Network Structure In A Long-Lived Insect, P. A. Cook, R. A. Costello, Vincent A. Formica, E. D. Brodie Iii

Biology Faculty Works

Social behaviors vary among individuals, and social networks vary among groups. Understanding the causes of such variation is important for predicting or altering ecological processes such as infectious disease outbreaks. Here, we ask whether age contributes to variation in social behavior at multiple levels of organization: within individuals over time, among individuals of different ages, among local social environments, and among populations. We used experimental manipulations of captive populations and a longitudinal dataset to test whether social behavior is associated with age across these levels in a long-lived insect, the forked fungus beetle (Bolitotherus cornutus). In cross-sectional analyses, …

Cell Surface And Plasma Biomarkers Of Kaposi Sarcoma, Sara R. Privatt

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

Kaposi sarcoma-associated herpesvirus is the etiological agent of several pathologies including Kaposi sarcoma, primary effusion lymphoma, and multicentric Castleman’s disease. Here, we investigated both the tumor microenvironment (TME) in KS lesions as well as plasma from KSHV-infected individuals and how metabolic dysfunction and dysregulated cytokines might have a systemic effect on KS tumorigenesis. Based on previously published KS tumor transcriptomics, one aspect of our investigation involved characterizing cell surface glycoproteins with potential to serve as therapeutic targets against KSHV-infected cells or KS tumors or as biomarkers for disease. Expression patterns of such markers may also suggest the cellular origin of …

Cronkhite-Canada Syndrome (CCS) is a rare, noninherited polyposis syndrome affecting 1 in every million individuals. Despite over 50 years of CCS cases, the etiopathogenesis and optimal treatment for CCS remains unknown due to the rarity of the disease and lack of model systems. To better understand the etiology of CCS, we generated human intestinal organoids (HIOs) from intestinal stem cells isolated from 2 patients. We discovered that CCS HIOs are highly proliferative and have increased numbers of enteroendocrine cells producing serotonin (also known as 5-hydroxytryptamine or 5HT). These features were also confirmed in patient tissue biopsies. Recombinant 5HT increased proliferation …

Patients with polymicrobial blood cultures or positive cultures from other sites were included if the organisms were sensitive to the incident antimicrobial; no concomitant antimicrobials could be used once …

Gene Variants In Bola-Dmb, Decr1, Fasn And Srebf1 Associated With Conceptus Death On Day 16 Of Pregnancy In Holstein Cows [Abstract], Carolina L. Gonzalez-Berrios, Courtney Bowden, Pablo J. Pinedo, Jeanette V. Bishop, Hana Van Campen, Thomas R. R. Hansen, Milton G. Thomas

United States Department of Agriculture Wildlife Services: Staff Publications

Investigating the influences of single nucleotide polymorphisms (SNP) associated with conceptus death (CD) on day 16 of pregnancy could distinguish cows who have inferior value for fertility traits. We hypothesized that CD is associated with SNP genotypes that disrupt maternal recognition and lead to early pregnancy loss. RNA sequences from Holstein cow pregnancies (n = 15) with normal conceptuses (Norm) or CD were subjected to SNP discovery via Qiagen CLC Genomics Workbench. Selected SNP were based on previous fertility studies, differentially expressed genes within pregnancy development analyses and proximity to SNP associated with fertility traits in the Cattle QTL …
