Chronic Stressors, Obesity Pathogenesis, And The Moderating Effect Of Internalized Weight Stigma; A Quantitative, Illinois Study, Karyn Byrne
Dissertations
The obesity epidemic is a ‘wicked’ problem with a complex web of determinants and outcomes. While generally higher for minoritized populations, prevalence rates manifest in surprising, nonlinear patterns. There is no consensus regarding treatment protocols or mitigation efforts, except that current efforts remain largely ineffective. Much research evidence that a profusion of determinants of health support obesity pathogenesis through various physiological processes and mechanisms, including the allostatic load, mitochondria functioning, the gut microbiome, and epigenetics. Intervening to support markers of the allostatic load (immunity, inflammation, and metabolic health) may provide a more effective treatment outcomes than traditional approaches, which tend …

Studying the involvement of nicotinic acetylcholine receptors (nAChRs), specifically α7-nAChRs, in neuropsychiatric brain disorders such as autism spectrum disorder (ASD) has gained a growing interest. The flavonoid apigenin (APG) has been confirmed in its pharmacological action as a positive allosteric modulator of α7-nAChRs. However, there is no research describing the pharmacological potential of APG in ASD. The aim of this study was to evaluate the effects of the subchronic systemic treatment of APG (10–30 mg/kg) on ASD-like repetitive and compulsive-like behaviors and oxidative stress status in the hippocampus and cerebellum in BTBR mice, utilizing the reference drug aripiprazole (ARP, 1 …

Emerging Unconventional Therapies For Glioblastoma Multiforme, Danielle Morang
Capstone Showcase
Glioblastoma multiforme (GBM) is the most prevalent and aggressive primary malignant brain tumor occurring in adults with a median survival of less than two years. It is a highly invasive tumor characterized by genetic heterogeneity, angiogenesis, and rapid proliferation. Patients undergo a multimodal treatment regimen consisting of surgical resection and chemoradiation therapy, yet GBM tumors almost always recur with a worsening prognosis. The molecular and genetic complexities of GBM pose a significant challenge for developing effective therapeutics. Thus, it is imperative to identify new therapeutic targets and explore novel treatment strategies to improve patients’ overall survival time and quality of …

PURPOSE. Patients deficient in peroxisomal β-oxidation, which is essential for the synthesis of docosahexaenoic acid (DHA, C22:6n-3) and breakdown of very-long-chain polyunsaturated fatty acids (VLC-PUFAs), both important components of photoreceptor outer segments, develop retinopathy present with retinopathy. The representative mouse model lacking the central enzyme of this pathway, multifunctional protein 2 (Mfp2−/−), also show early-onset retinal decay and cell-autonomous retinal pigment epithelium (RPE) degeneration, accompanied by reduced plasma and retinal DHA levels. In this study, we investigated whether DHA supplementation can rescue the retinal degeneration of Mfp2−/− mice. METHODS. Mfp2+/− breeding pairs and their offspring were fed a 0.12% DHA …

Despite efforts to identify modulatory neuroprotective mechanisms of damaging ischemic stroke cascade signaling, a void remains on an effective potential therapeutic. The present study defines neuroprotection by very long-chain polyunsaturated fatty acid (VLC-PUFA) Elovanoid (ELV) precursors C-32:6 and C-34:6 delivered intranasally following experimental ischemic stroke. We demonstrate that these precursors improved neurological deficit, decreased T2WI lesion volume, and increased SMI-71 positive blood vessels and NeuN positive neurons, indicating blood–brain barrier (BBB) protection and neurogenesis modulated by the free fatty acids (FFAs) C-32:6 and C-34:6. Gene expression revealed increased anti-inflammatory and pro-homeostatic genes and decreases in expression of pro-inflammatory genes in …

School of Medicine Faculty Publications
Docosahexaenoic acid (DHA; 22:6) plays a key role in vision and is the precursor for very-long-chain polyunsaturated fatty acids (VLC-PUFAs). The release of 32- and 34-carbon VLC-PUFAs and DHA from sn-1 and sn-2 of phosphatidylcholine (PC) leads to the synthesis of cell-survival mediators, the elovanoids (ELVs) and neuroprotectin D1 (NPD1), respectively. Macula and periphery from age-related macular degeneration (AMD) donor retinas were assessed for the availability of DHA-related lipids by LC-MS/MS-based lipidomic analysis and MALDI-molecular imaging. We found reduced retina DHA and VLC-PUFA pathways to synthesize omega-3 ELVs from precursors that likely resulted in altered disks and photoreceptor loss. Additionally, …
Differential Degeneration Of Neurons In A Mouse Model Of Canavan Disease, Vibha Chauhan, Quy Nguyen, Jeremy Francis, Paola Leone
Differential Degeneration Of Neurons In A Mouse Model Of Canavan Disease, Vibha Chauhan, Quy Nguyen, Jeremy Francis, Paola Leone
Rowan-Virtua Research Day
Canavan disease (CD) is an inherited leukodystrophy caused by inactivating mutations to the glial enzyme aspartoacylase (ASPA). ASPA catabolizes neuronal N-acetylaspartate (NAA) into free acetate and aspartate and loss of this function results in the chronic elevation of non-catabolized NAA and the failure of developmental myelination. Elevated NAA is thought to cause damage to myelin and myelin-producing cells (oligodendrocytes, but the viability of neurons in CD is relatively unexplored. We compare here the progressive degeneration of neurons in two regions of the CD mouse brain, the thalamus and the cortex, distinguished by differing degrees of vacuolation, and show that the …

Rowan-Virtua Research Day
Background: Increased blood-brain barrier (BBB) permeability is reported in both the neuropathological and in vivo studies in both Alzheimer’s Disease (AD) and age matched cognitively normal, no cognitive impairment (NCI), subjects. Impaired BBB allows various vascular components such as immunoglobulin G (IgG) to extravasate into the brain and specifically bind to various neuronal surface proteins (NSP), also known as brain reactive autoantibodies (BrABs). This interaction is predicted to further enhance deposition of amyloid plaques.
Hypothesis: Interaction between extravasated BrABs and its cognate NSPs lower the expression of that NSPs in AD patients.
Methods: We selected Western blotting technique to study …

Regeneration Of Neurons In Human Brain Tissue; A Revolutionary Concept With Therapeutic Potential, Mackenzie R. Dunn
Other Undergraduate Research
There is current research to suggest that endogenous neuronal regeneration, exogenous neuronal stem cell transplantation and glial cell reprogramming could be prospective therapeutic treatments for neurodegeneration and traumatic injury. With these conditions, there is significant brain atrophy, loss of neurons and loss of synaptic connections which can have devastating effects on executive functioning, cognition, learning and memory. This review will examine these modern approaches to adult neurogenesis, and assess the viable mechanisms and future outlook of these three therapies for neurological regenerative medicine.

A picture description task is a component of Miro Health’s platform for self-administration of neurobehavioral assessments. Picture description has been used as a screening tool for identification of individuals with Alzheimer’s disease and mild cognitive impairment (MCI), but currently requires in-person administration and scoring by someone with access to and familiarity with a scoring rubric. The Miro Health implementation allows broader use of this assessment through self-administration and automated processing, analysis, and scoring to deliver clinically useful quantifications of the users’ speech production, vocal characteristics, and language. Picture description responses were collected from 62 healthy controls (HC), and 33 participants …

Infiltrating Cd8+ T Cells Exacerbate Alzheimer’S Disease Pathology In A 3d Human Neuroimmune Axis Model, Jefin Jose, Devam Purohit
VCU's Medical Journal Club: The Work of Future Health Professionals
In this study, Jorfi et al. employed a neuroimmune axis model containing neurons, astrocytes, and microglia to examine the role of immune cells in Alzheimer's disease. Jorfi et al. found that T cells selectively infiltrated the BRAIN compartment of the neuroimmune axis model as compared to B cells and monocytes. Jorfi et al. further found that CD8+ T cells demonstrated heightened cytotoxicity in the Alzheimer's disease brain, illuminating the role of immune cells in neurodegeneration. Upon further examination, the CXCR3-CXCL10 signaling pathway was found to have an important role in inflammation.
A Genome-Wide In Vivo Crispr Screen Identifies Essential Regulators Of T Cell Migration To The Cns In A Multiple Sclerosis Model, Jefin Jose
VCU's Medical Journal Club: The Work of Future Health Professionals
Kendirli et al. (2023) used a CRISPR screen to determine the proteins involved in T cell migration into the CNS in multiple sclerosis. Overall, eighteen facilitators and five brakes to T cell infiltration into the CNS were identified. Kendirli et al. specifically identified ITGA4, FERMT3, and HSP90B1 to make up the adhesion module, CXCR3, GNAI2, and TBX21 to make up the chemotaxis module, and GRK2 and S1PR2 to make up the egress module. This study demonstrated the ability of a CRISPR screen to identify elements in a disease process and thus identify targets for future multiple sclerosis therapies.
Examining A Blood Biomarker Approach To Blood-Brain Barrier Disruption, Samantha Ford
Examining A Blood Biomarker Approach To Blood-Brain Barrier Disruption, Samantha Ford
Theses and Dissertations--Medical Sciences
Blood-brain barrier disruption has been identified to associate with the pathogenesis several neurological diseases such as dementia [1, 2], multiple sclerosis[3, 4], acute or chronic cerebral ischemia[5], brain trauma[5], meningitis[5], encephalitis[5], stroke[6], and seizures[7]. Being able to effectively identify blood-brain barrier disruption is limited in methodology. The current standard is using a cerebrospinal fluid (CSF) albumin to serum albumin index, which requires the use of a lumbar puncture. A novel method of identifying blood-brain barrier disruption utilizing blood biomarkers is proposed in this study. Participants in this study had previously collected blood and CSF samples, which were analyzed to compare …

This study examines the consequences of Alzheimer’s in rat and mice test subjects. The goal is to identify the effects of certain NLRP3 inhibiting drugs and to see if there are any noticeable effects in regards to impeding the pathological development of Alzheimer’s disease. The results are visualized by implementing the immunohistochemical process to identify neurodegeneration in the brain and to assess the expression levels of amyloid beta as an indicator of Alzheimer’s pathology. Other tests are also conducted on these transgenic mice to gauge cognitive functioning levels during the onset of their disease, those being behavior tests, but not …

The neurodegenerative disease field has enjoyed extremely limited success in the development of effective therapeutics. One potential reason is the lack of disease models that yield accurate predictions and optimal therapeutic targets. Standard clinical trials have pre-determined a single treatment modality, which may be unrelated to the primary drivers of neurodegeneration. Recent proof-of-concept clinical trials using a precision medicine approach suggest a new model of Alzheimer’s disease (AD) as a chronic innate encephalitis that creates a network insufficiency. Identifying and addressing the multiple potential contributors to cognitive decline for each patient may represent a more effective strategy. Here we review …

Extracellular accumulation of amyloid-beta (Aβ) plaques is one of the major pathological hallmarks of Alzheimer's disease (AD), and is the target of the only FDA-approved disease-modifying treatment for AD. Accordingly, the use of transgenic mouse models that overexpress the amyloid precursor protein and thereby accumulate cerebral Aβ plaques are widely used to model human AD in mice. Therefore, immunoassays, including enzyme-linked immunosorbent assay (ELISA) and immunostaining, commonly measure the Aβ load in brain tissues derived from AD transgenic mice. Though the methods for Aβ detection and quantification have been well established and documented, the impact of the size of the …

Schizophrenia (SZ) is one of the most severe forms of mental illness, yet mechanisms remain unclear. A widely established brain finding in SZ is hippocampal atrophy, and a coherent explanation similarly is lacking. Epidemiological evidence suggests increased cerebrovascular and cardiovascular complications in SZ independent of lifestyle and medication, pointing to disease-specific pathology. Endothelial cell contributions to blood-brain barrier (BBB) compromise may influence neurovascular unit and peripheral vascular function, and we hypothesize that downstream functional and structural abnormalities may be explained by impaired BBB.

Altered lipid metabolism is implicated in the risk of sporadic Alzheimer’s disease (AD) and related dementias (ADRD); however, the precise mechanisms accounting for findings from observational studies remains to be fully elucidated.
Plasmalogens are a subclass of integral membrane phospholipids with unique properties that appear to play important roles relevant to the pathophysiology of AD and ADRD, including vesicle fusion necessary for synaptic neurotransmitter release, modulation of membrane fluidity and microdomain dynamics, membrane antioxidant functions, and neuroprotection. Like the more familiar phosphatides, plasmalogens are synthesized on a 3-carbon glycerol backbone; however, they differ from phosphatides by the presence of a …

The objective of this study was to begin to determine the neurobiological underpinnings of psychosocial stress-induced cocaine seeking. Social defeat stress, achieved using the well-established resident-intruder procedure, is an ecologically-valid psychosocial stressor in rodents that may more closely recapitulate those psychosocial experiences that elicit cocaine craving and relapse in human cocaine users. Our laboratory has developed a model of psychosocial stress-induced relapse in rats in which extinguished cocaine seeking is reinstated by re-exposure to a discrete cue that signals impending social defeat stress. We previously reported that an individual rat’s predilection towards the display of active coping behaviors during prior …

Opioids exert their abuse-related effects by enhancing dopamine (DA) neurotransmission within the brain’s mesolimbic reward system, a neural projection involving DA neurons in the ventral tegmental area (VTA) that project to medium spiny neurons within the nucleus accumbens (NAc). Mu (MOR) are expressed by several populations of GABAergic neurons that tonically inhibit VTA DA neurons. By inhibiting these GABAergic neurons in a MOR-dependent manner, opioids indirectly enhance DA neurotransmission via disinhibition of DAergic neurons. Accumulating evidence indicates that selective pharmacological antagonism of the dopamine D3 receptor (D3R) attenuates the abuse-related effects of several opioids, but the neurobiological mechanisms mediating this …

Effects Of Gaba On Inflammation And Intestinal Barrier Disruption, Tyrel W. Long
EWU Masters Thesis Collection
Gut dysbiosis and intestinal barrier disruption have been linked to multiple sclerosis (MS). Our previous works show that experimental autoimmune encephalomyelitis (EAE) induction modifies the gut's microbiota composition, reducing frequencies of gamma-aminobutyric acid (GABA)-producing bacteria. GABA levels are reduced in the brains and circulation of MS patients. We engineered Lactococcus lactis with extra copies of gadB (glutamic acid decarboxylase) and gadC (glutamate/GABA antiporter) to increase GABA levels produced by the bacterium (GAD-L. lactis). EAE studies showed that the treatment with GAD-L. lactis and not with a L. lactis control expressing an empty plasmid (P-L. lactis) reduced the severity of the …

Acute ischemic stroke (AIS) is a common devastating disease that has increased yearly in absolute number of cases since 1990. While mechanical thrombectomy and tissue plasminogen activator (tPA) have proven to be effective treatments, their window-of-efficacy time is very short, leaving many patients with no viable treatment option. Over recent years there has been a growing interest in stimulating the facial nerves or ganglions to treat AIS. Pre-clinical studies have consistently demonstrated an increase in collateral blood flow (CBF) following ganglion stimulation, with positive indications in infarct size and neurological scores. Extensive human trials have focused on trans-oral electrical stimulation …
