Invisible Shipwrecks And Neurological Endangerment: The Trade-Off In Seeking Asylum - Reframing The Neurobiological Cost Of Forced Migration, Eisha Giran

CISLA Senior Integrative Projects

Forced migration along the Spain–Morocco route represents one of the most visible humanitarian crises of the twenty-first century, yet its neurological dimensions remain insufficiently examined. This paper investigates how prolonged displacement and trauma reshape neural systems involved in stress regulation, memory, and emotional processing. It introduces the concept of neurological endangerment, defined as a condition of prolonged and inescapable threat exposure during forced migration in which stress-response systems remain chronically activated, opportunities for recovery are structurally constrained, and cumulative neurobiological risk persists beyond the period of immediate danger.

To address the gap between biological measurement and lived experience, this paper …

Epigenetic Mechanisms For Mediating The Transmission Of Prenatal Maternal Stress And Associated Neurodevelopmental Outcomes, Kaylee Vis

Senior Honors Theses

The hypothalamic-pituitary-adrenal (HPA) axis is the primary stress response system responsible for regulating cortisol release. During pregnancy, maternal stress can dysregulate the HPA axis, leading to elevated cortisol and corticosterone levels that impact fetal development. Excessive prenatal exposure to stress has been associated with alterations in fetal brain structure and function, increasing the risk for neurodevelopmental disorders such as autism spectrum disorder, attention-deficit/hyperactivity disorder, and anxiety. Emerging research supports the idea that these neurodevelopmental effects may be transmitted through epigenetic mechanisms. However, a gap remains in the literature regarding the specific mechanism of interaction between environmental stressors, heritable epigenetic information, …

Eeg Signatures Of Motor Development In Early Childhood: A Systematic Review, Sonia Khurana, Ashwini Kulkarni, Thomas C. Bulea, Hunter J. Bennett

Rehabilitation Sciences Faculty Publications

Background

Early identification of motor developmental disorders is limited due to lack of objective neural markers that characterize typical neurodevelopmental patterns. This systematic review interprets and synthesizes existing evidence to propose a framework of EEG signatures associated with motor development in children aged 0-5 years, which may help inform future benchmarks for early assessment and intervention.

Methods

Following PRISMA guidelines, we searched published and gray literature across five databases between 2000 and 2025 (registered protocol). Included studies examined EEG during task-based, resting-state, or sleep studies linked to motor milestones, task performance, or standardized motor assessments. Study quality was assessed using …

Micu2 Controls Mitochondrial Calcium Signaling And Migration In Neurons During Development, Elena Berezhnaya, Benjamín Cartes-Saavedra, Raghavendra Singh, Macarena Rodríguez-Prados, Orly Reiner, Fowzan S Alkuraya, György Hajnóczky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Neurological disorders are linked to mitochondrial dysfunction and calcium overload. Mitochondrial calcium uptake is mediated by the mitochondrial calcium uniporter (mtCU), regulated by MICU1, which can be either homodimerized or heterodimerized with MICU2 or MICU3. Though MICU2 is scarce in the adult brain, MICU2 loss in patients leads to a neurodevelopmental disorder. We hypothesized that MICU2 is required for developmental calcium signaling and neuronal migration. MICU2 is present in the developing mouse brain but disappears by maturation, contrasting with other mtCU subunits that increase. MICU2 loss in mice does not affect cytoplasmic calcium but augments the mitochondrial matrix calcium rise …

Developmental Effects On Zebrafish Embryos Exposed To Alcohol, Tamya Mchaney

Science University Research Symposium (SURS)

Zebrafish are a good organism model due to their similarities with human biology. The transparency of their embryos allows for an easier view to see the developmental stages of the embryos, and easily and accurately note any mutations or defects in any of the embryos. In addition, they make excellent candidates to track potential effects that mirror human embryos with ethanol and alcohol will have on their developmental stages. The aim of this study was to measure the genetic size developmental differences of the embryo’s lens, eyes, and heart that are given 1% alcohol and 2% alcohol. This study’s experimental …

Psychology Faculty Articles and Research

Background

Unpredictable childhood experiences are an understudied form of early-life adversity that impact neurodevelopment. The neurobiological processes by which exposure to early-life unpredictability impact development and vulnerability to psychopathology remain poorly understood. In the current study, we investigated the sex-specific consequences of early-life unpredictability on the limbic network, focusing on the hippocampus and the amygdala.

Methods

Participants included 150 youths (54% female). Early-life unpredictability was assessed using the Questionnaire of Unpredictability in Childhood (QUIC). Participants engaged in 1 or more task–functional magnetic resonance imaging scans between the ages of 8 and 17 (223 total observations) measuring blood oxygen level–dependent (BOLD) …

Data interoperability is crucial for effectively combining data for scientific inquiry. To facilitate interoperability, data standards such as a common definition of variables are often developed. The Open Data Commons for Spinal Cord Injury (odc-sci.org) has established an initial set of community-based data elements (CoDEs)—a minimal set of variables for sharing—to promote data interoperability in SCI research, aligning with FAIR (Findable, Accessible, Interoperable, and Reusable) data principles. We sought to understand the use of CoDEs by the SCI community to inform current standards adherence and future standards development. We systematically analyzed 39 public datasets in relation to 17 required CoDEs …

Plasma S100Β Is A Predictor For Pathology And Cognitive Decline In Alzheimer’S Disease, Geetika Nehra, Bryan J. Maloney, Rebecca Smith, Wijitra Chumboatong, Erin L. Abner, Peter T. Nelson, Björn Bauer, Anika M. S. Hartz

UK CARES Faculty Publications

Background Blood–brain barrier dysfunction is one characteristic of Alzheimer’s disease (AD) and is recognized as both a cause and consequence of the pathological cascade leading to cognitive decline. The goal of this study was to assess markers for barrier dysfunction in postmortem tissue samples from research participants who were either cognitively normal individuals (CNI) or diagnosed with AD at the time of autopsy and determine to what extent these markers are associated with AD neuropathologic changes (ADNC) and cognitive impairment.

Methods We used postmortem brain tissue and plasma samples from 19 participants: 9 CNI and 10 AD dementia patients who …

Blood Biomarkers In Down Syndrome: Facilitating Alzheimer’S Disease Detection And Monitoring, Melissa E. Petersen, Lisi Flores-Aguilar, Elizabeth Head, Laia Montoliu-Gaya, Andre Strydom, Sarah E. Pape, Juan Fortea, Nicholas J. Ashton, Chinedu Udeh-Momoh, Sid E. O’Bryant, Dwight German, Florin Despa, Mark Mapstone, Henrik Zetterberg

Neurology Faculty Publications

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer’s Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …

The Cochrane Risk of Bias 2.0 Tool and GRADE were used for risk and evidence certainty assessments. Meta-analysis or narrative synthesis was performed based on data …

Investigating Tumor Growth And Regulation In Supratentorial Ependymomas; The Impact Of Dlk1 And Egr1 Knockout, Om Sinojia

Honors Scholar Theses

Ependymomas (EPNs) are primary brain tumors that often arise from radial glial cells lining the ventricular system. Supratentorial ependymomas (ST-EPNs) are particularly aggressive, and understanding the molecular factors driving their growth is critical for developing targeted therapies. This study investigates the roles of DLK1 and EGR1, key regulators in cellular differentiation and tumorigenesis, in the development of ST-EPNs. We utilized genetically engineered mouse models to induce postnatal knockouts of DLK1 and EGR1 and evaluated tumor growth using histological and imaging techniques. Tumor area was quantified across multiple brain sections from both male and female mice. DLK1 knockout brains exhibited consistent …

Many coronavirus disease 2019 (COVID-19) positive individuals exhibit abnormal electroencephalographic (EEG) activity reflecting “brain fog” and mild cognitive impairments even months after the acute phase of infection. Resting-state EEG abnormalities include EEG slowing (reduced alpha rhythm; increased slow waves) and epileptiform activity. An expert panel conducted a systematic review to present compelling evidence that cognitive deficits due to COVID-19 and to Alzheimer’s disease and related dementia (ADRD) are driven by overlapping pathologies and neurophysiological abnormalities. EEG abnormalities seen in COVID-19 patients resemble those observed in early stages of neurodegenerative diseases, particularly ADRD. It is proposed that similar EEG abnormalities in …

Characterizing Border Associated Macrophages During Spinal Cord Regeneration, Addison Vogt, Dana Shaw, Mayssa Mokalled

Undergraduate Research Symposium

The human central nervous system has limited regenerative ability, with injuries to the spinal cord (SC) often resulting in paralysis. Alternatively, zebrafish have enhanced innate regenerative capacity and regain full motor function following spinal cord injury (SCI). Immune activation following SCI is necessary to provide a permissive environment for tissue repair, but the immune pathways necessary for SC regeneration are not well characterized. In previous data, we have found that while immune activation is persistent into the chronic phases of SCI response in mammals, zebrafish achieve full immune clearance within 48 days post SCI. We hypothesize that one key distinction …

Multiple Guidance Mechanisms Control Axon Growth To Generate Precise T-Shaped Bifurcation During Dorsal Funiculus Development In The Spinal Cord, Bridget M. Curran, Kelsey R. Nickerson, Andrea R. Yung, Lisa V. Goodrich, Alexander Jaworski, Marc Tessier-Lavigne, Le Ma

Farber Institute for Neuroscience Faculty Papers

The dorsal funiculus in the spinal cord relays somatosensory information to the brain. It is made of T-shaped bifurcation of dorsal root ganglion (DRG) sensory axons. Our previous study has shown that Slit signaling is required for proper guidance during bifurcation, but loss of Slit does not affect all DRG axons. Here, we examined the role of the extracellular molecule Netrin-1 (Ntn1). Using wholemount staining with tissue clearing, we showed that mice lacking Ntn1 had axons escaping from the dorsal funiculus at the time of bifurcation. Genetic labeling confirmed that these misprojecting axons come from DRG neurons. Single axon analysis …

Immunopathogenesis Of Post-Infectious Hydrocephalus, Sascha Powers Bernier

Honors Scholar Theses

Hydrocephalus is characterized by the abnormal accumulation of cerebrospinal fluid (CSF) within the brain ventricles. In post-infectious hydrocephalus (PIH) cases, the condition presents challenges in understanding the immune response. PIH is a complex condition, often persisting after the initial infection is treated and thus requiring a deeper understanding of the immune mechanisms involved in its development. This thesis will explore the immunopathogenesis of PIH, elucidating the relationship between the immune response and neurological complications that would succeed infection. The immune response of PIH includes a series of events, beginning with the activation of immune cells and finishing with the release …

Use Of Cre-Lox Mice As A Model For Ependymogenesis, Poorva Bagchee

Honors Scholar Theses

Stem cells in the lateral ventricles of the brain undergo a process of development within the ventricular-subventricular zone. In early development neuroepithelial cells divide to form more neuroepithelial cells or convert to radial glial cells (RGCs). These RGCs, or stem cells, then divide to form neurons or other glial cells such as ependymal cells, which form a single-layered ependyma along the ventricular wall. These stem cells divide in two ways: symmetrically, producing two ependymal cells or asymmetrically, yielding one neural stem cell and ependymal cell. To further study this process the Cre-lox system in mice will be used. By breeding …

Development Of Vasculature Patterns In A Mouse Model Of Supratentorial Ependymoma, Jackson Ayers

Honors Scholar Theses

Supratentorial Ependymoma (ST-EPN) is a subtype of ependymoma, a primary solid tumor found throughout the nervous system. ST-EPN are most commonly caused by an oncogenic fusion between the zinc finger gene ZFTA and the RELA, and this distinct ependymoma subtype is readily modeled in mice by conditional expression of ZFTA-RELA in radial glial cells. ST-EPN are known to have a distinctive arrangement of tumor cells and vasculature forming pseudo-rosettes in which polarized tumor cells surround blood vessels within the tumors. It is not known how these pseudo-rosettes or the tumor vasculature form and develop in ST-EPN, so in this study …

INTRODUCTION: Protein-based plasma assays provide hope for improving accessibility and specificity of molecular diagnostics to diagnose dementia. METHODS: Plasma was obtained from participants (N = 837) in our community-based University of Kentucky Alzheimer’s Disease Research Center cohort. We evaluated six Alzheimer’s disease (AD)- and neurodegeneration-related (Aβ40, Aβ42, Aβ42/40, p- tau181, total tau, and NfLight) and five inflammatory biomarkers (TNF𝛼, IL6, IL8, IL10, and GFAP) using the SIMOA-based protein assay platform. Statistics were performed to assess correlations. RESULTS: Our large cohort reflects previous plasma biomarker findings. Relationships between biomarkers to understand AD–inflammatory biomarker correlations showed significant associations between AD and inflammatory …

Azithromycin Reduces Hemoglobin-Induced Innate Neuroimmune Activation, Chirayu D. Pandya, Hemendra J. Vekaria, Miriam Zamorano, Amanda L. Trout, Rodney M. Ritzel, Gary Guzman, Christopher Bolden, Patrick G. Sullivan

Neurology Faculty Publications

Neonatal intraventricular hemorrhage (IVH) releases blood products into the lateral ventricles and brain parenchyma. There are currently no medical treatments for IVH and surgery is used to treat a delayed effect of IVH, post-hemorrhagic hydrocephalus. However, surgery is not a cure for intrinsic brain injury from IVH, and is performed in a subacute time frame. Like many neurological diseases and injuries, innate immune activation is implicated in the pathogenesis of IVH. Innate immune activation is a pharmaceutically targetable mechanism to reduce brain injury and post-hemorrhagic hydrocephalus after IVH. Here, we tested the macrolide antibiotic azithromycin, which has immunomodulatory properties, to …

Different Cohort, Disparate Results: Selection Bias Is A Key Factor In Autopsy Cohorts, Kathryn Gauthreaux, Walter A. Kukull, Karin B. Nelson, Charles Mock, Yen-Chi Chen, Kwun C. G. Chan, David W. Fardo, Yuriko Katsumata, Erin L. Abner, Peter T. Nelson

Neurology Faculty Publications

INTRODUCTION: Research-oriented autopsy cohorts provide critical insights into dementia pathobiology. However, different studies sometimes report disparate findings, partially because each study has its own recruitment biases. We hypothesized that a straightforward metric, related to the percentage of research volunteers cognitively normal at recruitment, would predict other inter-cohort differences.

METHODS: The National Alzheimer’s Coordinating Center (NACC) provided data on N = 7178 autopsied participants from 28 individual research centers. Research cohorts were grouped based on the proportion of participants with normal cognition at initial clinical visit.

RESULTS: Cohorts with more participants who were cognitively normal at recruitment contained more individuals who …

Markey Cancer Center Faculty Publications

Background

Patients with Alzheimer’s disease (AD) develop blood–brain barrier dysfunction to varying degrees. How aging impacts Aβ pathology, blood–brain barrier function, and cognitive decline in AD remains largely unknown. In this study, we used 5xFAD mice to investigate changes in Aβ levels, barrier function, and cognitive decline over time.

Methods

5xFAD and wild-type (WT) mice were aged between 9.5 and 15.5 months and tested for spatial learning and reference memory with the Morris Water Maze (MWM). After behavior testing, mice were implanted with acute cranial windows and intravenously injected with fluorescent-labeled dextrans to assess their in vivo distribution in the …

Oxidative Stress Alters Mitochondrial Homeostasis In Isolated Brain Capillaries, Gopal V. Velmurugan, Hemendra J. Vekaria, Anika M. S. Hartz, Björn Bauer, William Brad Hubbard

Markey Cancer Center Faculty Publications

Background

Neurovascular deficits and blood-brain barrier (BBB) dysfunction are major hallmarks of brain trauma and neurodegenerative diseases. Oxidative stress is a prominent contributor to neurovascular unit (NVU) dysfunction and can propagate BBB disruption. Oxidative damage results in an imbalance of mitochondrial homeostasis, which can further drive functional impairment of brain capillaries. To this end, we developed a method to track mitochondrial-related changes after oxidative stress in the context of neurovascular pathophysiology as a critical endophenotype of neurodegenerative diseases.

Methods

To study brain capillary-specific mitochondrial function and dynamics in response to oxidative stress, we developed an ex vivo model in which …

Proteasome Inhibition Protects Blood–Brain Barrier P-Glycoprotein And Lowers Aβ Brain Levels In An Alzheimer’S Disease Model, Milica Vulin, Yu Zhong, Bryan J. Maloney, Björn Bauer, Anika M. S. Hartz

Markey Cancer Center Faculty Publications

Background Loss of P-glycoprotein (P-gp) at the blood–brain barrier contributes to amyloid-β (Aβ) brain accumulation in Alzheimer’s disease (AD). Using transgenic human amyloid precursor protein (hAPP)-overexpressing mice (Tg2576), we previously showed that Aβ triggers P-gp loss by activating the ubiquitin–proteasome pathway, which leads to P-gp degradation. Furthermore, we showed that inhibiting the ubiquitin-activating enzyme (E1) prevents P-gp loss and lowers Aβ accumulation in the brain of hAPP mice. Based on these data, we hypothesized that repurposing the FDA-approved proteasome inhibitor, bortezomib (Velcade®; BTZ), protects blood–brain barrier P-gp from degradation in hAPP mice in vivo.

Methods We treated hAPP mice with …

Bisphenol-A And Phthalate Metabolism In Children With Neurodevelopmental Disorders, T Peter Stein, Margaret D Schluter, Robert A Steer, Xue Ming

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: The etiology of autism spectrum (ASD) and Attention Deficit/Hyperactivity (ADHD) disorders are multifactorial. Epidemiological studies have shown associations with environmental pollutants, such as plasticizers. This study focused on two of these compounds, the Bisphenol-A (BPA) and Diethylhexyl Phthalate (DEHP). The major pathway for BPA and DEHP excretion is via glucuronidation. Glucuronidation makes insoluble substances more water-soluble allowing for their subsequent elimination in urine.

HYPOTHESIS: Detoxification of these two plasticizers is compromised in children with ASD and ADHD. Consequently, their tissues are more exposed to these two plasticizers.

METHODS: We measured the efficiency of glucuronidation in three groups of children, …

Effects Of Withania Somnifera On Zebrafish, Diyari Bekhtyar

Student Works

Withania somnifera (commonly known as Ashwagandha), is a plant in which its root powder is sold as a dietary supplement. It is being commonly used as an anti-anxiety supplement to combat stress. While the sale of Withania somnifera is widely accessible and available throughout the U.S., it is concerning that a number of teens and young adults are taking this supplement without consulting a physician. Previous studies and claims conclude that Withania somnifera has both neuroprotective and antiinflammatory properties in human neuronal cells. We have chosen to test Withania somnifera’s effects on early embryonic development using Danio rerio, zebrafish, as …

Neural Mechanisms Of Language Development In Infancy, Scott Huberty, Christian O'Reilly, Virginia Carter Leno, Mandy Steiman, Sara J. Webb, Mayada Elsabbagh, The Basis Team

Publications

Understanding the neural processes underpinning individual differences in early language development is of increasing interest, as it is known to vary in typical development and to be quite heterogeneous in neurodevelopmental conditions. However, few studies to date have tested whether early brain measures are indicative of the developmental trajectory of language, as opposed to language outcomes at specific ages. We combined recordings from two longitudinal studies, including typically developing infants without a family history of autism, and infants with increased likelihood of developing autism (infant-siblings) (N = 191). Electroencephalograms (EEG) were recorded at 6 months, and behavioral assessments at …
