In Silico Studies Of Hiv-1 Vpr R77q Mutant’S Structure And Stability, Linnea Mason, Sidney T. Sithole, Bradford K. Berges

Library/Life Sciences Undergraduate Poster Competition 2026

Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that infects CD4+ T cells. Without treatment, infection with HIV-1 usually leads to acquired immunodeficiency syndrome (AIDS), which is characterized as severe immunosuppression (CD4+ count: < 200cells/mm3 of blood). However, some individuals do not advance to AIDS and are known as long-term non-progressors (LTNP). Interestingly, a small viral protein of HIV-1, called viral protein R (Vpr), has been associated with HIV-1 progression. The R77Q mutant has been linked to the LTNP phenotype and increased levels of apoptosis; however, the mechanisms behind it are not yet understood [1]. Previously, our group has found that Vpr was expressed at lower levels in cells infected with R77Q virus compared to the wildtype (WT) virus by western blot [1]. Image quantification of the bands showed an approximate six-fold reduction in protein levels.

Hamstrings Strength Is Influenced By Participation In Sports And Body Mass Across All Ages, Isaiah Guymon, Malorie Wilwand, A. Wayne Johnson

Library/Life Sciences Undergraduate Poster Competition 2026

Hamstrings (HS), is a group of 4 muscles in the legs.

With age, muscles atrophy in part from factors related to age and increased sedentary behavior.

The Nordic curl is an eccentric HS exercise often used in athlete training. The Nordboard is a device that measures this eccentric force while performing a Nordic curl.

PURPOSE: To examine and compare eccentric (lengthening phase of a movement) hamstrings average (avg) and max force production across varying sports and age.

Exploring The Impact Of Redox Perturbations On Optic Tectum Development And Behavior, Kevin Gray, Bailey Calder, Daniel Andersen, Parker Hamblin, Michael Zeyer, Arminda Suli

Library/Life Sciences Undergraduate Poster Competition 2026

The optic tectum (OT), the non-mammalian counterpart of the mammalian superior colliculus (SC), integrates multisensory information and orchestrates behavioral responses such as reflexive movements and attention shifts. It is localized in the midbrain, where anterior-posterior patterning is regulated by transcription factors dependent on proper endogenous H2O2 levels. Recent studies have implicated the OT/SC and early redox imbalance in neurodevelopmental disorders such as autism spectrum disorder (ASD). Given the importance of H2O2 in midbrain development, we are investigating how redox perturbations may lead to atypical OT circuitry development and, subsequently, result in aberrant behavioral phenotypes, similar to those associated with ASD. …

Enhancing Metabolic Fitness Of Car T-Cells By Removing Cd6, Nate Neyman, Alka Guar, Annie Joy-Larson, Collin Mickelson, Scott Weber

Library/Life Sciences Undergraduate Poster Competition 2026

Honorable Mention - Poster Design

CAR T-cell therapy is a highly effective cancer treatment involving engineering the patient’s T-cells to recognize and kill cancerous cells. This therapy has shown great success for blood cancers but has faced many challenges against solid tumors.

Surrounding tumor cells there is a lack of essential nutrients (oxygen, glucose) for T-cells to metabolize efficiency. Additionally, there is a buildup of excess waste products that directly impair T-cell function (1). To overcome these obstacles, scientists are working on developing longer lasting T-cells with improved metabolism to improve efficacy against cancer cells.

The Story Behind The Waves: Effects Of Urbanization And Female Presence On Waving Behavior In Fiddler Crabs, Katelyn Hansen, Blaine Griffen

Library/Life Sciences Undergraduate Poster Competition 2026

Animal communication plays a central role in survival and reproduction, allowing individuals to convey information about their quality, territory, and reproductive statuses. Because signaling behaviors are often energetically costly and are dependent on both social contexts and habitat, they are sensitive to environmental conditions. Previous research has shown that male sand fiddler crabs (Leptuca pugilator) produce two distinct wave types: D-waves (typically directed towards other males) and up-and-down waves (typically directed toward females), and that they also reduce their waving behavior under urban stress. Urbanization introduces stressors such as habitat alteration and increased disturbances that can change the frequency and …

Cholesterol‑Containing Membranes Decrease The Helicity Of The Snare Protein Snap‑25, Christopher E. Hunt Jr., Jason T. Carlson, Michael B. Connell, Fatima D. Dagohoy, Mike Sumison, Jonathan Madsen, Chase M. Tingen, Azer E. White, Tanner M. Blocker, Dixon J. Woodbury

Library/Life Sciences Undergraduate Poster Competition 2026

Neurotransmitter release in neurons requires membrane fusion between synaptic vesicles and the presynaptic membrane. Lipids in both membranes merge through the action of SNARE proteins including SNAP-25. Changes in SNAP-25 structure or lipid composition likely modify this process. SNAP-25 has two isoforms, SNAP-25A (25A) and SNAP-25B (25B), the expression patterns of these isoforms vary throughout different brain regions and neuronal developmental stages. In vivo SNAP-25 anchors to the presynaptic membrane via attachment of palmitic acid to at least one of the four cysteines. Here we show mixing SNAP-25 (not palmitoylated) with liposomes alters both protein structure and lipid properties. Using …

Library/Life Sciences Undergraduate Poster Competition 2026

The Mafia mouse model expresses the green fluorescent protein (GFP) in cells that utilize the macrophage-specific c-fms promoter. The c-fms promoter controls expression of receptor for Colony Stimulating Factor 1. We hypothesize that this promotor may be utilized in bone marrow progenitor cells in addition to the mature cell expression already known in macrophage lineage cells. For this study, bone marrow cells were analyzed by flow cytometry for the expression of c-fms, early progenitor markers, and lineage-specific markers. Expression was also mapped on a Ly6CxCD31 plot, which has been used to distinguish cells based on developmental stage and lineage. This …

Cd6-Knockout Car-T Cells Display Enhanced Cytotoxicity Against Lymphoma Cell Line, Annie Larson, Alka Gaur, Nate Neyman, Collin Mickelson, K. Scott Weber

Library/Life Sciences Undergraduate Poster Competition 2026

Chimeric antigen receptor (CAR)-T cells are genetically engineered T cells that target surface antigens on cancer cells, showing remarkable effectiveness in treating blood cancers [1]. However, CAR-T cells are currently not effective in treating solid tumors, as the tumor microenvironment poses physical and metabolic barriers to effective CAR-T cell function. A notable strategy for increasing CAR-T cell cytotoxicity in a tumor microenvironment is knocking out or overexpressing some genes of the T cell.

Distinct from the task of predicting the author of a document (authorship attribution), we focus on addressing the issue of how to estimate the similarity between the written language styles of authors. To do so, we present a dataset of metadata derived by asking human annotators, who were presented with three documents, to identify which two were written by the same author and which was written by a different author. The dataset has over 400 such annotations, creating a companion to the Amazon Web Services (AWS) customer review dataset, laying the groundwork for crowdsourcing applications to other natural language processing …
