While immunotherapy is a promising treatment strategy for cancer, the majority of head and neck squamous cell carcinoma (HNSCC) patients treated with single-agent immunotherapy do not respond. Therefore, researchers are investigating combination treatments with immunostimulatory molecules that can maximize anti-tumor responses. Cyclic dinucleotides (CDNs) are STING agonists that hold promise in combination approaches, but they require frequent intratumoral administration when used in both preclinical models of HNSCC and clinical trials. To reduce administration frequency, we have created a peptide hydrogel–liposome composite system, K2-Lip(CDN), for local and prolonged availability of CDN. We investigated the loading limits of cationic liposomes in both …

Faculty, Staff and Student Publications

Purpose: Stroke risk correlates with the Biffl grading system in blunt cerebrovascular injury (BCVI). Although anti-thrombotic therapy is the mainstay of stroke prevention, no point-of-care clinical decision-support tool exists to guide timing for therapy. We sought to develop an interactive online calculator that incorporates patient-specific demographic and injury characteristics to estimate stroke risk and risk reduction with anti-thrombotic (AT) administration.

Methods: Data from BCVI patients (n = 1,197) at a Level I Trauma Center were retrospectively collected. Six machine learning methods were employed to predict stroke risk with and without AT therapy. Class imbalance was addressed using downsampling and/or class …

A Tv-Bm3d Iterative Algorithm For Vmat-Ct Reconstruction

Faculty, Staff and Students Publications

Volumetric modulated arc therapy-computed tomography (VMAT-CT), which is the CT reconstructed using the portal images collected during VMAT, can potentially be an effective onsite imaging tool. The goal of this study was to propose an iterative reconstruction algorithm that can further improve the image quality of VMAT-CT and reduce the number of failed reconstructions. An iterative algorithm combining total variation (TV) with block-matching and 3D filtering (BM3D) was proposed, addressing the L1-L2 regularization problem using the split Bregman method. We collected portal images from 67 VMAT cases including 50 phantom and 17 real-patient cases. Both Feldkamp-Davis-Kress (FDK) and TV-BM3D iterative …

Faculty, Staff and Students Publications

Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality and is largely driven by metabolic disorders such as obesity and type 2 diabetes. The AMP-activated protein kinase (AMPK) is a master regulator of metabolism, and its activation has been proposed as a therapeutic strategy for treating metabolic disorders. However, although AMPK activity is down-regulated in HCC, the precise role of AMPK in HCC development has not been clearly delineated. Here, we investigated the ability of constitutive AMPK activation to prevent HCC development using a constitutively active AMPK transgenic mouse model and a pharmacological AMPK activator. We observed that AMPK …


Car-T Cell Therapy – A Revolutionizing Cancer Treatment Through Precision Immunotherapy, Mackenzie R. Epperson Apr 2026

Car-T Cell Therapy – A Revolutionizing Cancer Treatment Through Precision Immunotherapy, Mackenzie R. Epperson

ATU Scholars Symposium

Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a great advancement in the field of oncology, offering a targeted and adaptable cancer treatment. Traditional therapies, including surgery, chemotherapy, and radiation often have limitations, such as relapse and resistance, highlighting the need for more precise therapeutic options. CAR-T therapy addresses many of these challenges through engineering a patient’s own T-cells to recognize and destroy cancerous cells with specificity and long-lasting immune activity. Since being approved by the FDA in 2017, CAR-T therapy has shown success in treating hematologic malignancies, demonstrating high remission rates in patients with previously limited options. Despite …

The generation of hepatocyte-like cells (HLCs) from human pluripotent stem cells (hPSCs) holds great promise for drug discovery and cell-based therapy for liver disease. However, current differentiation protocols are complicated and unstable, and the underlying gene regulatory mechanisms of hepatic differentiation remain incompletely defined. Here, we developed a machine learning-based artificial intelligence (AI) tool using phase-contrast images of hepatic progenitor cells (HPCs), which are essential for generating HLCs. The AI tool significantly improves the success rate of hepatic differentiation without the need for immunostaining or lineage tracing. By optimizing the methodology, we achieved an impressive purity of 90-95% for HLCs …

Faculty, Staff and Student Publications

Background: Stimulant use disorders (StimUDs), including cocaine and methamphetamine use disorders, remain a major public health concern in the United States with no US Food and Drug Administration (FDA)-approved pharmacological treatments. The early recovery period following stimulant use is marked by sleep disturbances, heightened stress reactivity, and dysregulated reward processing, contributing to high rates of resumption of use. Evidence from animal and human studies supports the orexin neuropeptide system as a promising therapeutic target for minimizing these disruptive mechanisms. Suvorexant, an FDA-approved dual orexin receptor antagonist for insomnia, has previously been shown to improve sleep, reduce stress, and attenuate craving …

Viral infection polarizes monocyte-derived dendritic cells (moDC) to initiate type 1 immunity. The availability of overlapping (homologous) MHC class I and II epitopes, an occurrence frequently and primarily associated with intracellular infection, significantly enhances this process; however, the underlying mechanism(s) are unclear. We demonstrate that moDC loaded with homologous MHC epitopes acquire a cDC1-like phenotype in a process governed by mTORC1. mTORC1 pathway inhibition leads to NF-κB-mediated expression of IL-12 and other type I immune polarizing genes. The observed cDC1-like gene signature was also significantly enhanced in clinical moDC vaccine products made through methodologies that enforced class I and II …

Faculty, Staff and Student Publications

Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) is an established marker of normal and cancer stemlike cells. LGR5 has been implicated in promoting cancer cell plasticity that drives tumorigenesis, metastasis, and therapeutic resistance. LGR5 rapidly and constitutively internalizes and potentiates Wnt (Wingless/Int-1)/β-catenin and adhesion signaling pathways, though its precise mechanisms and interacting partners remain unresolved. An improved understanding of LGR5 signaling may provide invaluable insight into its intricate and important functions in cancer progression. Moreover, several LGR5-targeting therapies, including peptibody- and antibody-drug conjugates and bispecific antibodies, are showing promising efficacy and tolerability in colorectal cancer and other tumor types. This …

Faculty, Staff and Student Publications

Background: Autism spectrum disorder (ASD) is a developmental disorder that has increased in prevalence over the years. Diagnosis and subsequent intervention by the age of 3 is essential for development. However, recent estimates indicate that less than 50% of children receive an evaluation by age 3. Underserved populations are more likely to receive an evaluation at an older age. Several barriers in the diagnostic process have been identified; however, limited studies have aimed at understanding the specifics of these barriers among underserved populations and whether current strategies are beneficial for all children.

Objectives: The aim of this study was to …

Systemic neoadjuvant chemotherapy, often combined with immunotherapy, is the standard of care for early-stage, non-breast cancer susceptibility gene (BRCA)-mutant triple negative breast cancer (TNBC). However, up to 70% of patients retain residual disease after treatment, which is linked to recurrence and mortality within 5 years. To define mechanisms of resistance, we performed single-cell RNA sequencing on orthotopic TNBC patient-derived xenografts during a cycle of treatment with doxorubicin and cyclophosphamide (AC). Clustering identified four tumor epithelial cell populations, with basal cells enriched in residual tumors. These basal cells up-regulated C15ORF48, a paralog of the mitochondrial cytochrome c oxidase associated subunit FA4 …

Predicting Ventilation From Single Breathing Phase Non-Contrast Ct Using Swin Transformers, Yi-Kuan Liu, Hsu-Ting Kuo, Alaa Melek, Richard Castillo, Yevgeniy Vinogradskiy, Lili Zhao, Girish Nair, Edward Castillo

Department of Radiation Oncology Faculty Papers

BACKGROUND: Pulmonary ventilation imaging enables functional avoidance radiotherapy treatment plans by quantifying regional lung function. However, current clinical standards, such as 99𝑚Tc-based single-photon emission computed tomography (SPECT), rely on radioactive tracers, which can introduce imaging deposition artifacts. CT ventilation imaging (CTVI) methods based on both physical models and deep learning approaches currently require multiple CT images as input, such as the inhale/exhale phases of a 4DCT. While the theoretical foundation of physics-based CTVI is built on multi-phase information, the feasibility of single-phase deep learning CTV models has not been determined.

PURPOSE: While deep learning methods have predicted SPECT ventilation from …

Hyperglycemia And Mycoplasma Pneumoniae Cards Toxin Impacts On Lung Epithelial And Fibroblast Injury And Recovery, Alejandra Y. Delgado, Naila Villagomez, Shuri Magdalene

Posters - 2026

Mycoplasma pneumoniae CARDS toxin induces cytotoxicity and inflammation in lung epithelial cells²·¹⁰·¹¹, while hyperglycemia independently elevates ROS and disrupts fibroblast repair¹·⁵·⁸, contributing to the heightened respiratory infection severity seen in diabetic patients¹. However, the interaction between hyperglycemic conditions and CARDS toxin-induced lung injury remains unexplored.

This study investigates how increasing high-glucose (HG) pre-conditioning modifies CARDS toxin-induced injury and recovery in A549⁶ and IMR-90⁷ cells compared to normal glucose (NG ≈ 5mM) controls. We hypothesized that increasing glucose pre-conditioning concentrations would produce a dose-dependent increase in CARDS toxin-induced oxidative stress¹² and inflammatory cytokine production¹⁵ in IMR-90 and A549 compared with normal …

Background: Apolipoprotein E (APOE) genotype influences the presence, course and severity of sporadic cerebral amyloid angiopathy (sCAA). We investigated the effect of the APOE ε4-allele on clinical and neuroradiological outcomes in mutation-carriers with Dutch-type hereditary (D-)CAA. Methods: Participants with D-CAA from a prospective cohort study, with data collected on history of symptomatic intracerebral hemorrhages (sICH) and vascular risk factors, underwent 3 Tesla magnetic resonance imaging (MRI) scans to assess macrobleeds, cerebral microbleeds (CMBs), cortical superficial siderosis (cSS), enlarged perivascular spaces (EPVS), white matter hyperintensity (WMH) volume and WMH multispot lesions. Global cognition was measured using Montreal Cognitive Assessment (MoCA) and …

Dendritic cells (DCs) are derived from hematopoietic stem cells of the bone marrow. They are the most efficient antigen presenting cell, presenting antigens to T cells to initiate clonal expansion and differentiation of the T cells into memory and effector cells. Thus, activating the effector functions of T cells in cell-mediated and humoral immune responses (2). Community-acquired respiratory distress syndrome (CARDS) toxin is produced by Mycoplasma pneumoniae that causes acute and chronic lung infections (4). Dendritic cells play a key role in the immune response to respiratory mycoplasmas (3). However, the mechanism underlying in DC and CARDS toxin interactions are …
