The underlying molecular processes of aberrant protein expression in neurodegeneration are intricate and multifaceted, with ribosome-associated quality control (RQC) emerging as a promising avenue of exploration. Ribosome-associated quality control is integral to cellular function. Its evolutionarily conserved pathway encompasses a network of mechanisms designed to ensure the fidelity of protein synthesis, folding, and degradation within the cells of all eukaryotes. The ribosome, central to protein synthesis, plays a pivotal role in this quality control network, and its malfunction can lead to the accumulation of misfolded or aberrant proteins. In the context of neurodegenerative disorders, this dysfunction can have dire consequences. …

Evaluation Of Sleep Outcomes After Traumatic Brain Injury In Children Using Questionnaires And Actigraphy, Connie Tran, Sydney Weese, Cydni Williams Md
Student Research Symposium
Traumatic brain injuries are the result of a sudden external blunt force to the brain and can result in long-term complications or death. In pediatrics, it is the leading cause of acute and chronic sleep wake disturbances, as well as cognitive deficits, which can lead to a reduction in the quality of life. These impairments can later result in lowered performance in work and school settings or decreased psychosocial function. Although there is sufficient evidence that traumatic brain injuries contribute to is that it is unknown whether or not sleep wake disturbances contribute to an increase in the mentioned cognitive …

Neuroscience Educational Interventions For Mental Health Management Within The Neurodiverse Population: A Working Model, Kadi Rae Smith, C.K. Miller, Bill Griesar, Jeff Leake
Student Research Symposium
Sociological and environmental factors such as economic disparity and cultural marginalization hinder access to educational and medical resources and must be taken into account to ensure accurate diagnoses, effective self-regulation and mental health management for neurodiverse individuals, and offset disparities in access to healthcare and education. Arbitrary attachment of stigma to traits commonly associated with neurodivergence perpetuate neuro-myths1 that have dire consequences when internalized, informing individuals’ development and sense of self. Neuroscience outreach done by NW Noggin is an active model for engaging communities with limited resources and a greater need for services to offset economic disparity. Integrated arts programming …
Understanding The Importance Of Social Emotional Learning In Children And The Link Between Mental Health, Lynette Marie Lubiak
Understanding The Importance Of Social Emotional Learning In Children And The Link Between Mental Health, Lynette Marie Lubiak
Student Research Symposium
I will examine how very important it is to society to teach structured Social Emotional Learning (SEL) programs to children in school. It can bring mental wellbeing and the ability to have healthy relationships, non addictive behaviors and being able to emotionally regulate themselves. Since we have pushed on only academia and not SEL for our children, mental illness has skyrocketed. This problem started after the SEL part of school was taken out of schools and then the division between rich and poor became wider and wider as time went on. If we were to bring back SEL into school, …

Investigating The Antibacterial And Immunomodulatory Effects Of Resolvin D2 On Monocytes And Macrophages, Cristina Maria Padovani
Theses and Dissertations
In the late phase of sepsis, immunosuppression occurs, where the host is unable to clear the pre-existing infection and is susceptible to secondary infections. It is believed that the ideal treatments for sepsis should attenuate immunosuppression so that the host can get back to homeostasis. Specialized Pro-resolving Mediators (SPMs) are endogenously- produced fatty acids that resolve infectious inflammation without being immunosuppressive. We hypothesize that an SPM – Resolvin D2 (RvD2) – can augment exhausted macrophage function during the immunosuppressive phase of sepsis. We developed a two-hit model to establish macrophage exhaustion in vitro, and found that RvD2 increased NF-κB activity, …
Individual Differences In Age And Testosterone Are Uniquely Associated With Neural Oscillatory Activity Serving Verbal Working Memory In Children And Adolescents, Abraham D. Killanin
Individual Differences In Age And Testosterone Are Uniquely Associated With Neural Oscillatory Activity Serving Verbal Working Memory In Children And Adolescents, Abraham D. Killanin
Theses & Dissertations
During the sensitive period of adolescence, the human brain undergoes dynamic changes in structure and function resulting in vast executive function gains. Verbal working memory (VWM) is one executive function that serves as a foundation to language acquisition, reading, and learning. Many have examined the development of VWM in youth, but few have probed age-related changes in the underlying neural oscillatory dynamics, and none have examined testosterone-related changes. We recorded magnetoencephalography during a modified Sternberg VWM task in 82 youth participants aged 6 – 14 years old and collected salivary testosterone samples. Significant oscillatory responses were identified and imaged using …
How Does Schizophrenia Affect The Expression Of Alpha 7 Nicotinic Acetylcholine Receptors In The Brain?, Shruti Varshney, Nimish Acharya
How Does Schizophrenia Affect The Expression Of Alpha 7 Nicotinic Acetylcholine Receptors In The Brain?, Shruti Varshney, Nimish Acharya
Rowan-Virtua Research Day
Schizophrenia (SZ) is a psychiatric disorder with a pathophysiology that has not yet been fully understood. This mental illness is characterized by disruptions in cognition, social activity, affect, and perception, and affects approximately 0.085% of individuals worldwide. The Alpha 7 Nicotinic Acetylcholine Receptor (α7nAChR) has been connected to auditory function gating deficits. The purpose of this review is to understand the current literature in how the levels of α7nAChR expression and function are affected by SZ, information that could be used to develop therapies to modulate auditory hallucinations in patients with SZ. A literature search was conducted for peer-reviewed journal …

Background: The blood-brain barrier (BBB), formed by the vascular endothelium, astrocytic foot processes, pericytes, is a highly selective barrier that is responsible for maintaining brain homeostasis and ultimately proper neuronal function. Disruption of the BBB, leading to increased BBB permeability, has been reported in several neurodegenerative diseases, including Alzheimer’s disease (AD) and traumatic brain injury (TBI).1 Loss of BBB integrity leads to the proliferation of pro-inflammatory cytokines, including TNFɑ, IL-1β, and IL-6.2 Moderate inflammation has a beneficial response in the system following an acute injury. However, prolonged inflammation has been known to perturb homeostasis and have …

It is theorized that low concentrations of dopamine (DA) and norepinephrine (NE) within in the prefrontal cortex (PFC) following traumatic brain injury (TBI) leads to increased risky behavior. Our lab has shown that repeated mild TBI (rmTBI) sex-differentially increases risky behavior in a rodent model. Methylphenidate (MPH) is a psychostimulant drug used to treat symptoms of Attention-Deficit Hyperactivity Disorder (ADHD), also driven by a hypo-catecholaminergic PFC. MPH elevates catecholamine levels by blocking DA and NE transporters, DAT and NET. While the potential of psychostimulants to treat post-TBI symptoms have been explored, the effects of sub-chronic MPH on transporter levels following …

6–7-week-old G93A SOD mice were given 1x1010 vector genomes of three different self-complimentary (sc) AAV capsid serotypes (AAV1, 2, and 9) all containing an identical CBh-driven GFP reporter expression cassette. Each serotype was delivered via either the intrathecal (IT) or intra cisterna magna (ICM) route of administration (ROA). Transduction by each serotype, via each of the two ROA was compared for the cortex and each of the lumbar, thoracic, and cervical regions of the spinal cord, with percent neuronal tropism calculated in each region. AAV2 was effective at transducing spinal cord neurons but disappointingly ineffective at transducing cortical neurons by …

Intra-Accumbens Microinfusion Of The Dopamine D3 Receptor Partial Agonist (±)Vk4-40 Does Not Affect Basal Locomotion In Mice, Yeonwoo Sim, Nicole M. Hinds, Amy Hauck Newman, Daniel F. Manvich
Rowan-Virtua Research Day
The opioid epidemic remains a pressing public health crisis, prompting the search for alternative pharmacotherapies for Opioid Use Disorder (OUD). This study explores the potential of the dopamine D3 receptor (D3R) partial agonist, (±)VK4-40, as a novel treatment option. We investigated the impact of intra-nucleus accumbens (NAc) microinfusion of VK4-40 on basal locomotion in mice. Results indicate that VK4-40 did not significantly alter basal locomotion, suggesting that its therapeutic effects may not be mediated through disruptions in generalized motor function. Future research will focus on elucidating the neuropharmacological mechanisms underlying VK4-40's therapeutic actions and exploring its effects on psychostimulant-induced hyperlocomotion. …

Many neurotropic viruses cause more significant pathology in younger hosts as their brains are still developing. This experiment asked how central nervous system (CNS) viral-infections affect the development of synapses in the pediatric brain during infection and post-infection. Synaptogenesis is at its peak in pediatric mice (10 days old) and we hypothesized that a neurotropic infection could disrupt synaptic proteins. We used a transgenic mouse model where measles virus (MV) infects only mature neurons, leading us to question whether synapses were impacted. We examined synaptic markers in the cerebellum and hippocampus in MV-infected and uninfected mice 9 days and 90 …

Rowan-Virtua Research Day
Traumatic Brain Injury (TBI) is a common cause of death and disability in the United States, and it can occur due to varied reasons including motor vehicle accidents, gunshot wounds, and falls. Following TBIs, patients are often left with lifelong disabilities and cognitive problems that can lead to increased risk-taking behaviors. The main goal of my research was to understand the neural mechanisms that drive increased risk-taking behaviors due to TBIs. The specific areas of the brain I was interested in looking at were the medial prefrontal cortex (mPFC), orbitofrontal cortex (OFC), and/or anterior cingulate cortex (ACC) of the prefrontal …

Parkinson’s Disease (PD) is a prevalent and devastating neurodegenerative disorder that causes progressively worsening motor symptoms affecting locomotor and oropharyngeal function. There is limited research in animal models on swallowing dysfunction in PD. To examine how neurodegeneration in PD produces progressive impairment in the oropharyngeal and locomotor processes, rotenone, a type II mitochondrial inhibitor, was injected into Lewis rat models to reproduce a parkinsonian phenotype. We hypothesized that the animal models injected with the rotenone will exhibit both oropharyngeal dysfunction and locomotor deficiency with an increased deficit that correlates with prolonged treatment. We utilized 18 rats receiving either 2.75 mg/kg …

Background: The blood-brain barrier (BBB) is responsible for maintaining brain homeostasis and ultimately proper neuronal function. Disruption of the BBB, leading to increased BBB permeability, has been reported in several neurodegenerative diseases, including Alzheimer’s disease (AD) and traumatic brain injury (TBI). Lipoxins (LXs) are a class of arachidonate-derived eicosanoids, which are a class of specialized pro-resolving lipid mediators (SPMs). SPMs are known to inhibit immune response through inhibition of cellular infiltration, downregulation of pro-inflammatory mediators and upregulation of anti-inflammatory mediators. Hence, LXs are recognized as “breaking signals” in the inflammatory process. One form of LXs, Lipoxin A4 (LXA4) …

Background: Schizophrenia (SZ) is a heterogenous psychiatric condition characterized by disruptions in cognition, social activity, affect, and perception often associated with a varied combination of positive and negative symptoms. The pathophysiology behind SZ remains poorly elucidated. Earlier reports have cited the importance of the alpha 7 nicotinic acetylcholine receptors (α7nAChR) in the hippocampus and the receptor’s association with auditory sensory gating and cognitive function. Specifically, variations in the expression and functionality of α7nAChR can be linked to auditory hallucinations experienced by patients with SZ and several therapies have been researched that target α7nAChRs. However, there are very few primary research …

Optimization Of Tyrosine Hydroxylase Antibody For Immunohistochemistry Fluorescence Detection In Zebrafish (Danio Rerio), Madison Thurber
Theses/Capstones/Creative Projects
Dopamine is an important neurotransmitter produced through the catecholamine synthesis pathway that affects brain activity. Unregulated dopamine levels can lead to various diseases such as Parkinson’s Disease or attention deficit hyperactivity disorder (ADHD). Optimization of an immunohistochemistry protocol will allow for the quantification of tyrosine hydroxylase antibody, which indirectly allows for dopamine quantification in dopaminergic regions within the brain. However, the antibody concentration to give the optimal signal-to-noise ratio in IHC varies across studies. Through this experiment, I determined the concentration of tyrosine hydroxylase (TyrH) antibody for immunohistochemistry that gave the best signal-to-background noise ratio within several known dopaminergic regions …

Role Of Proneurotrophin-P75ntr Signaling In A Mouse Model Of Depression, Kirsten Hodgson
All Graduate Theses and Dissertations, Fall 2023 to Present
Major depressive disorder, or depression, is among the leading causes of disability globally. Despite being a large public health challenge, depression remains difficult to treat as the underlying biology is still unknown and the currently available treatments are limited in effectiveness. This experiment was to test the efficacy of the drug LM11A-31, which works on the signaling pathway of proneurotrophin-p75NTR, a pathway that is not targeted by any currently used antidepressants. Male mice underwent a repeated forced swim, with all the mice receiving saline the first two days and then half the mice receiving saline and half receiving LM11A-31 before …

Microglia and their role as the immune cells of the central nervous system are an emerging area of interest within Alzheimer’s research, particularly as they have shown in a benevolent and malevolent cellular context. Models of Alzheimer’s disease are very light in studying microglia, so in this study a model of microglia isolated from aged mice is established in order to study the phagocytic activity and protein expression of microglia in response to Amyloid Beta. The cells were isolated from aged mice and cultured before being used to confirm cellular identity, as well as to measure phagocytic activity. This study …
Exploring Available Information On The Gut-Brain Axis And Alzheimer’S Disease For Clinicians Making Dietary Recommendations: A Scoping Review, Megan Gibson

Abstract: Alzheimer’s Disease (AD) is a complex neurodegenerative disease that requires interprofessional collaboration. Pharmacological options are currently ineffective, increasing the need for preventative strategies to combat the rise of AD. Considerations of gut-targeted interventions have increased as a key component in the prevention of AD, based on the understanding that the state of the gut microbiome can impact cognitive function through the pathway known as the gut-brain axis.
Methods: This scoping review explored information on the gut-brain axis in persons with AD. A comprehensive search was conducted in November 2023. Forty reviews and 13 human studies were analyzed.
Results: There …
Towards Understanding The Function Of An Ets-Like Gene In Nematostella Vectensis: Generation Of A Knockout Mutant Line And A Transgenic Reporter Line, Emily Bullock
Biological Sciences Undergraduate Honors Theses
Due to their unique phylogenic position as sister to Bilateria, Cnidaria are often credited with the utility of allowing for reconstruction of ancestral biology based on characteristics shared with bilaterians and other animals. This factor makes investigation into the nervous systems of cnidarians critical in understanding early neural evolution. Wamides, a class of neuropeptides, have been shown to play a regulatory role in life cycle transitions across many different species. The cnidarian specific Wamide neuropeptide, GLWamide, has previously been identified to play an accelerator role in the metamorphic timing of a specific species of sea anemone, Nematostella vectensis. However, …

Biophysical Model Of Retraction Motor Neurons And Their Modification By Operant Conditioning, Maria Rasheed
Dissertations & Theses (Open Access)
Operant conditioning (OC) is a form of associative learning in which an animal modifies its behavior based on the consequences that follow that behavior. Despite its ubiquity, the underlying mechanisms of OC are poorly understood. Insights into the mechanisms of OC can be obtained by studying Aplysia feeding behavior as it can be modified by OC. This behavior is mediated by a central pattern generator (CPG) network in the buccal ganglia that contains a relatively small number of neurons. This CPG generates rhythmic motor patterns (BMPs) that move food into the gut by closing a tongue-like structure (i.e., radula) during …

Evaluating Environmental Enrichment As A Preventative Treatment In A Zebrafish (Danio Rerio) Model Of Alzheimer's Disease, Ainsley Craddock
Undergraduate Honors Theses
Alzheimer’s Disease (AD) is a progressive neurodegenerative disorder that leads to several cognitive deficits, including impairments in spatial memory (Alzheimer’s Association, “What is Alzheimer’s Disease?,” 2024). This is thought to occur due to atrophy in the hippocampus and cholinergic system (Ferreira-Vieira et al., 2016). Acetylcholine receptor antagonists, such as scopolamine, can mimic the effects of AD by decreasing acetylcholine activity at muscarinic receptors in the hippocampus. Scopolamine is an antiemetic that is FDA approved to treat certain kinds of nausea, but it has become a popular pharmacological model for studying the cognitive impairments associated with AD (Bajo et al., 2015). …

Molecular Mechanisms Of Opioid Use Disorder In Human Brain Models, Emily Mendez
Dissertations & Theses (Open Access)
Opioid use disorder (OUD) is a national and global public health crisis with no end in sight. While studies from animal models hint at widespread epigenetic and transcriptomic alterations of opioid drugs, the molecular consequences of long-term exposure to opioid drugs in human brain is still unclear, and human-centered translational models are necessary to discern the human cell type-specific effects of OUD.
Using postmortem brain Brodmann area 9 (BA9) from the UTHealth Brain Collection for Research on Psychiatric Disorders, I identified angiogenic gene networks perturbed in the RNA and protein of OUD subjects, as well as downregulation of many neuron-correlated …

P300 Event-Related Potential Responses To Self-Relevant Stimuli, Jordan Razzak
Electronic Theses and Dissertations
Previous literature has suggested an apparent P300 sensitivity to self-relevant stimuli. To further explore this relationship, we asked participants to submit 10 photos, each of a particular category (e.g. footwear, plants), to be used as either targets or distractors in a given condition of an oddball task. Furthermore, we attempted to see whether the effect of self-relevance on the P300 could be induced in a participant by allowing them to study a set of unique photos which would then be used as targets. Our analysis suggested that P300 amplitude elicited in response to self-relevant stimuli used as targets was statistically …
Perinatal Buprenorphine Effects On Offspring Growth, Opioid Withdrawal, And Brain Morphology In Rats, Parker Barnes
Perinatal Buprenorphine Effects On Offspring Growth, Opioid Withdrawal, And Brain Morphology In Rats, Parker Barnes
Electronic Theses and Dissertations
Opioid use disorder (OUD) impacts 5.6 million people in the US. Buprenorphine (BUP) is a commonly prescribed opioid medication used to treat OUD, including in pregnant women. However, opioid use during pregnancy is associated with poorer infant outcomes including reduced fetal growth, neurodevelopmental deficits, and neonatal opioid withdrawal syndrome (NOWS). Recent clinical data suggests that providing mothers with a lower dose of BUP may result in fewer negative outcomes in infants. Here, a preclinical rodent model of low-dose perinatal BUP exposure was used to study offspring health outcomes in the neonate, juvenile, and adolescent offspring. Dams were given clinically relevant …
