Gene Therapy Strategies To Enhance Antifungal Immunity In Microgravity, Riley Dienna Aug 2026

Gene Therapy Strategies To Enhance Antifungal Immunity In Microgravity, Riley Dienna

Discovery Day - Daytona Beach

During spaceflight, the immune system of astronauts becomes impaired due to microgravity, resulting in increased susceptibility to infections caused by pathogens such as Candida albicans. One of the most common clinical treatments for aggressive candidiasis is amphotericin B, a polyene antimycotic that targeted ergosterol in the fungal cell membrane and compromised the stability of the membrane. However, due to the chemical similarities between ergosterol and cholesterol, this treatment also affects the somatic cells of patients it is administered to. A novel treatment is therefore required to combat the aggressive fungal infection while minimizing damage to the host’s cells. This project …


Using H2ax As A Biological Indicator To Assess Radiation-Induced Bone Loss In Microgravity Environments, Angeline Nichols, Enoch Tonkin, Ana Lobaton, Jahzara Hope Aug 2026

Using H2ax As A Biological Indicator To Assess Radiation-Induced Bone Loss In Microgravity Environments, Angeline Nichols, Enoch Tonkin, Ana Lobaton, Jahzara Hope

Discovery Day - Daytona Beach

Long-duration space missions expose astronauts to microgravity and chronic low-dose radiation, both greatly impacting skeletal health. While mechanical unloading in microgravity is a well-known driver of bone loss, recent evidence indicates that radiation independently contributes to bone deterioration by increasing osteoclast activity, which remodel bone faster, and suppress osteoblast differentiation. H2AX, a histone protein that rapidly phosphorylates into y-H2AX in response to the double strands of DNA breaking, has emerged as a sensitive biological marker for radiation exposure. This project aims to determine the efficacy of H2AX in the presence of radiation-induced DNA damage in bone marrow, compared to microgravity …

Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards Aug 2026

Simulating Pacemakers And Heartbeat Recovery Through Mathematical Modeling, Thomas Estrada, Jayla Edwards

Discovery Day - Daytona Beach

Title: Simulating Pacemakers and Heartbeat Recovery Through Mathematical Modeling   This study utilizes the Fitzhugh-Nagumo model to simulate cardiac electrical activity and the regulatory role of pacemakers through ordinary differential equations (ODEs). By defining the rate of change for membrane voltage, 𝑑𝑣/dt, and a recovery variable, 𝑑𝑤/dt, the model captures the heart's excitability and resting states. Central to the analysis is the stimulus current parameter, which represents the "kick" provided by a pacemaker to correct flatline conditions or weak heartbeats. Using Euler’s method for numerical integration, the research compares unstable cardiac rhythms against corrected periodic oscillations. Additionally, the project implements vector …


Translational Reading Frame Predicts The Pathogenicity Of C-Terminal Frameshift Deletions In Mecp2, Jacky Guy, Elena Hein, Beatrice Alexander-Howden, Timur Von Bock Und Polach, Tricia Mathieson, Benjamin P Kleinstiver, Huda Y Zoghbi, Adrian Bird Aug 2026

Translational Reading Frame Predicts The Pathogenicity Of C-Terminal Frameshift Deletions In Mecp2, Jacky Guy, Elena Hein, Beatrice Alexander-Howden, Timur Von Bock Und Polach, Tricia Mathieson, Benjamin P Kleinstiver, Huda Y Zoghbi, Adrian Bird

Duncan NRI Faculty and Staff Publications

Mutations in the MECP2 gene cause the severe neurological disorder Rett syndrome. A cluster of frameshift-causing C-terminal deletions (CTDs) removes ~100 amino acids and accounts for approximately 10% of RTT-causing mutations. Their pathogenicity is unexpected because this C-terminal domain is dispensable in mice. Analysis of pathogenic and benign human MECP2 variants reveals that some individuals with apparently typical CTDs do not develop Rett syndrome, confirming that C-terminal truncations are not intrinsically pathogenic. Using human sequence data and mouse models we show that pathogenicity results from a marked reduction in MeCP2 levels and depends on the presence of a proline proline …

The Role Of Chimeric Antigen Receptor Regulatory T Cells In Promoting Immune Tolerance In Solid Organ Transplantation: Mechanisms And Therapeutic Potential, Maher S. Alwethaynani

Saudi Medical Journal

Solid organ transplantation (SOT) is a life-saving procedure for patients with end-stage organ failure; however, lifelong immunosuppressant use is needed to prevent allograft rejection. These drugs increase the risk of non-Hodgkin lymphoma, liver, kidney, and lung cancers, and heighten susceptibility to oncogenic viruses, including hepatitis B and Epstein-Barr virus. The usage of chimeric antigen receptor (CAR) regulatory T (Treg) cells is a promising approach to induce transplant tolerance while minimizing dependence on immunosuppressants. The CAR Tregs offer the potential to enhance graft survival and quality of life by reducing immunosuppressant-related morbidity and mortality. Despite remarkable progress in transplantation tolerance, challenges …
