LINGO4 is a leucine-rich repeat and immunoglobulin-like domain-containing transmembrane protein encoded immediately adjacent to Rorc, the gene for RORγt, raising the possibility that it contributes to the biology of RORγt+ lymphocytes. However, its impact on these cells and resistance to enteric infections has remained unknown. Here, we identify LINGO4 as a critical regulator of group 3 innate lymphoid cells (ILC3s). Lingo4-/- ILC3s exhibit a profound, cell-intrinsic defect in IL-22 production linked to impaired STAT3 activation, mitochondrial dysfunction, elevated ROS, and increased apoptosis. In vivo, Lingo4 deficiency also drives a dysbiotic gut microbiota, resulting in an additional, microbiota-dependent loss of ILC3s. …

Quantification Of Sarm1 Nadase Activity In Human Peripheral Blood Mononuclear Cells, Lila F Dabill, Ivana R Shen, Jennifer M Brazill, Alicia Neiner, Yo Sasaki, Erica L Scheller

2020-Current year OA Pubs

SARM1 (sterile α and TIR motif-containing protein-1) is an NADase enzyme that serves as the central executioner of Wallerian axon degeneration. Given this, SARM1 is of high interest as a candidate therapeutic target, and SARM1 inhibitors are currently in clinical trials for treatment of neurodegeneration. Beyond neuroscience, emerging studies reveal that SARM1 may also drive aspects of bone fragility, liver pathology, adipose expansion, and insulin resistance in metabolic disease. However, we lack methods to quantify SARM1 activation in humans to better define patients at high risk of SARM1-mediated tissue damage. Unlike neurons, peripheral blood mononuclear cells (PBMCs) represent an easily …


Harnessing Mechanobiology Of Resident Stem Cells To Refine Cell Based Therapeutics, Dakota R. Kamm May 2026

Harnessing Mechanobiology Of Resident Stem Cells To Refine Cell Based Therapeutics, Dakota R. Kamm

WUSM Theses and Dissertations – All Programs

Mesenchymal stem cells (MSCs) are resident cells residing with many adult tissues such as adipose tissue and bone marrow that have the potency for multiple lineage differentiation as well as the capacity to secrete a litany of beneficial factors to maintain homeostasis and promote tissue repair. Since 1995, MSCs have been used therapeutically to treat a variety of conditions from osteoarthritis to heart disease to muscle pathologies. Great leaps have been made in improving MSC-based therapies through optimization of culture methods and select enrichment of cellular subpopulations. More recently, the physical microenvironment of tissue in vivo and culture conditions in …

2020-Current year OA Pubs

BACKGROUND: Systemic inflammation is hypothesized to contribute to post-traumatic stress disorder (PTSD) vulnerability. Few studies have examined inflammation shortly after trauma as a predictor of later PTSD symptoms. We examined whether inflammation from the emergency department (ED) post-trauma is associated with PTSD symptom severity over the following 6 months.

METHODS: Our sample included 742 AURORA participants, a longitudinal cohort of patients in 29 EDs across the United States after a traumatic stressor, followed up to 6 months. Plasma cytokines were assessed from a study blood draw in the ED: an inflammatory index (standardized sum of generally pro-inflammatory markers interleukin [IL]-6, …

2020-Current year OA Pubs

A key methodological challenge for genome-wide association studies is how to leverage haplotype diversity and allelic heterogeneity to improve trait association power, especially in noncoding regions where it is difficult to predict variant impacts and define functional units for variant aggregation. Genealogy-based association methods have the potential to bridge this gap by testing combinations of common and rare haplotypes based purely on their ancestral relationships. In parallel work, we have developed an efficient local ancestry inference engine and a novel statistical method (LOCATER) for combining signals present on different branches of a locus-specific haplotype tree. Here, we develop a genome-wide …

2020-Current year OA Pubs

BACKGROUND: The modified Blalock-Taussig-Thomas shunt (mBTTS) is a critical palliative procedure for infants with single-ventricle physiology, but thrombosis-related occlusion affects 8% to 12% of infants and carries nearly 50% mortality. Meanwhile, existing antithrombotic strategies fail to address the hemodynamic factors driving thrombosis, highlighting the need for a deeper understanding of flow dynamics in shunt failure.

OBJECTIVES: This study aims to identify how mBTTS geometry influences hemodynamics and thrombosis risk, providing quantitative guidance for surgical planning and shunt design optimization.

METHODS: We used patient-specific imaging data to test 54 idealized mBTTS configurations, systematically varying key geometric factors: pulmonary artery diameter, shunt …

Best Practice: Ct-Guided Adaptive Radiotherapy Reference Planning On The Ethos Platform, Xenia Ray, Joseph Harms, Alex Price, Mu-Han Lin, Dennis N Stanley

2020-Current year OA Pubs

Online adaptive radiotherapy (ART) enables treatment plan modifications based on the patient's anatomy at each fraction, addressing limitations of conventional radiotherapy that relies on a static pre-treatment plan. CT-guided ART (CTgART), as implemented on the Varian Ethos platform, has gained increased clinical adoption over the past several years; however, its success is highly dependent on reference plan design due to limited on-table planning flexibility. As a result, clinicians creating and reviewing reference plans will greatly benefit from both understanding how upstream planning decisions affect the downstream adaptive process and proactively incorporating strategies that improve optimization robustness and efficiency on-treatment. We …

2020-Current year OA Pubs

BACKGROUND: Preterm birth increases the long-term risk of diabetes and chronic kidney disease (CKD), yet its impact on diabetic kidney disease (DKD) is unclear. We previously showed that male preterm mice with diabetes develop early features of DKD, including reduced podocyte density, decreased renin expression, activation of angiogenesis pathways, and impaired endothelial-podocyte signaling. Here, we examine whether preterm birth similarly accelerates DKD progression in female mice and compare structural and transcriptomic outcomes in the females to the prior male cohort to assess sex-specific differences.

METHODS: Preterm mice were delivered by Caesarean section at 19 days post conception (dpc) and term …

2020-Current year OA Pubs

OBJECTIVES: Children with differentiated thyroid cancer (DTC) often present with lung metastases but historically have good outcomes. Radioactive iodine (RAI) is commonly used to treat these children. Given the rarity of this condition, little evidence detailing long-term outcomes and risk of radiation pneumonitis exists.

METHODS: We conducted a retrospective analysis of patients < 20 years old who received RAI for DTC lung metastases between 1973 and 2018. Disease-free survival (DFS) was calculated from diagnosis to last follow-up. Overall survival and rates of acute and late radiation pneumonitis were determined by chart review and obituary searches.

RESULTS: Sixteen patients met eligibility criteria. Fourteen presented with thyroid, nodal, and lung disease; one presented with thyroid and nodal disease with nodal and lung recurrence; and one presented with thyroid-only disease with nodal and lung recurrence. All patients underwent thyroidectomy, 10 underwent neck dissection, and four underwent …

UNLABELLED:

IMPORTANCE: Dual membrane-spanning anti-sigma factors (Dma) are a novel class of regulatory proteins found solely among Bacteroidota. Previous studies demonstrated the importance of Dma1 in vesiculation, but the overall role of the Dma family in Bacteroides physiology remains poorly understood. Here, we show that Dma2 modulates vesiculation and the expression of select polysaccharide utilization loci (PULs) that target host-associated glycans

Ready-to-use therapeutic and supplementary foods (RUTF/RUSF) are a primary treatment for childhood malnutrition in Community Management of Acute Malnutrition (CMAM) programs. However, measuring intervention compliance is labor intensive and unreliable. We applied FoodSeq, a fecal genomic dietary assessment biomarker, in malnourished infants (3-15 months) from Matiari, Pakistan. FoodSeq identified a significant increase in the abundance of DNA from chickpea, a primary RUSF ingredient, during RUSF administration and captured region-specific complementary feeding practices, including age-inappropriate feeding practices such as wide-spread tea consumption. Our findings highlight the potential of dietary genomics as an empirical and scalable tool for compliance monitoring and dietary …

Mitochondrial Presequences Harbor Variable Strengths To Maintain Organellar Function, Youmian Yan, Baigalmaa Erdenepurev, Thiago N Menezes, Ian Collinson, Natalie M Niemi

2020-Current year OA Pubs

Hundreds of mitochondrial proteins rely on N-terminal presequences for organellar targeting and import. While generally described as positively charged amphiphilic helices, presequences lack a consensus motif and thus likely promote protein import into mitochondria with variable efficiencies. Indeed, the concept of presequence strength underlies biological models such as stress sensing, yet a quantitative analysis of what dictates strong versus weak presequences is lacking. Furthermore, the extent to which presequence strength affects mitochondrial function and cellular fitness remains unclear. Here, we capitalize on the MitoLuc protein import assay to define multiple aspects of presequence strength. We find that select presequences, including …

Eeg In Patients With Altered Mental Status In The Emergency Department, Mariama Runcie, Neal Nolan, Olivia Yoo, Robert Silbergleit, Fábio A Nascimento, Maura Kennedy, M Brandon Westover, Joshua N Goldstein

2020-Current year OA Pubs

BACKGROUND: Altered mental status is a common chief complaint in the emergency setting, and the initial evaluation often fails to find an etiology. Subclinical (electrographic) seizures and nonconvulsive status epilepticus (NCSE) are potential causes of delirium and altered mental status, but require electroencephalogram (EEG) for diagnosis. It is not clear how often subclinical seizure or NCSE is present in those with undifferentiated altered mental status, nor which patients are most likely to benefit from emergent EEG. METHODS: We performed a retrospective review of patients presenting to a single academic medical center emergency department (ED) over a one-year period with the …

Artificial intelligence (AI) is increasingly being integrated into everyday tasks and work environments. However, its adoption in medical image analysis has progressed more slowly due to high clinical stakes, limited availability of labeled data, and substantial variability in imaging protocols and population. These challenges are further pronounced in the field of fetal, infant, and toddler (FIT) neuroimaging, where datasets are especially scarce and subject to large amounts of anatomical variability. However, deep learning (DL), a specific method within machine learning, which is itself a subfield of AI, has emerged as a powerful framework to adapt to the challenges of medical …
