Pharmacy Faculty Articles and Research

Tumor necrosis factor alpha (TNF-α) plays a vital role in Alzheimer’s disease (AD) pathology, and TNF-α inhibitors (TNFIs) modulate AD pathology. We fused the TNF-α receptor (TNFR), a biologic TNFI that sequesters TNF-α, to a transferrin receptor antibody (TfRMAb) to deliver the TNFI into the brain across the blood–brain barrier (BBB). TfRMAb-TNFR was protective in 6-month-old transgenic APP/PS1 mice in our previous work. However, the effects and safety following delayed chronic TfRMAb-TNFR treatment are unknown. Herein, we initiated the treatment when the male APP/PS1 mice were 10.7 months old (delayed treatment). Mice were injected intraperitoneally with saline, TfRMAb-TNFR, etanercept (non-BBB-penetrating …

Cholesterol levels have been repeatedly linked to Alzheimer's Disease (AD), suggesting that high levels could be detrimental, but this effect is likely attributed to Low-Density Lipoprotein (LDL) cholesterol. On the other hand, High-Density Lipoproteins (HDL) cholesterol levels have been associated with reduced brain amyloidosis and improved cognitive function. However, recent findings have suggested that HDL-functionality, which depends upon the HDL-cargo proteins associated with HDL, rather than HDL levels, appears to be the key factor, suggesting a quality over quantity status. In this report, we have assessed the HDL-cargo (Cholesterol, ApoA-I, ApoA-II, ApoC-I, ApoC-III, ApoD, ApoE, ApoH, ApoJ, CRP, and SAA) …

Heavy alcohol consumption is a known risk factor for various forms of dementia and the development of Alzheimer’s disease (AD). In this work, we investigated how intragastric alcohol feeding may alter the liver-to-brain axis to induce and/or promote AD pathology. Four weeks of intragastric alcohol feeding to mice, which causes significant fatty liver (steatosis) and liver injury, caused no changes in AD pathology markers in the brain [amyloid precursor protein (APP), presenilin], except for a decrease in microglial cell number in the cortex of the brain. Interestingly, the decline in microglial numbers correlated with serum alanine transaminase (ALT) levels, suggesting …

Myasthenia Gravis, Rebecca Wheeler

Nursing Student Class Projects (Formerly MSN)

Myasthenia gravis (MG), a neuromuscular and autoimmune disorder, is not completely understood by clinicians and scientists. The primary cause is thought to be anti-Acetylcholine receptor antibodies that attack the neuromuscular junction, causing destruction of post-synaptic junctional folds and blockade of the receptor. This causes frequent weakness and fatigability of voluntary muscles, making activities of daily living difficult for those living with MG. Although it is not an incredibly prevalent disease, the incidence is increasing in the United States due to better testing and diagnosis. Treatments are available, including cholinesterase inhibitors that raise the concentration of Acetylcholine at the neuromuscular junction …

Full- Versus Sub-Regional Quantification Of Amyloid-Beta Load On Mouse Brain Sections, Yuu Ohno, Riley Murphy, Matthew Choi, Weijun Ou, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

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 …

A Preliminary Investigation Of Neuroantibody Levels, Prevalence, And Environmental Factors In Patients With Neurological Dysfunction, Jihan Azar

Theses and Dissertations

Nervous system damage comprises a large proportion of diseases worldwide. It is also the most difficult to diagnose. Biomarkers for nervous system damage are needed in order to diagnose these diseases early enough to allow for intervention. In this study, we recruited patients from two Egyptian hospitals with MCI, ET and NMS and health references. Serum autoantibody levels against neural proteins and heavy metals were analyzed and compared. Immunoglobulin G (IgG) antibodies against neurofilament H (NFH), Glial Fibrillary Acidic Protein (GFAP), Myelin Basic Protein (MBP) and alpha synuclein (a-SYN) and Immunoglobulin M (IgM) antibody against neurofilament light (NFL) were among …

Cyclin C Is Sufficient For Myoblast Differentiation-Induced Mitochondrial Fragmentation, Alicia N. Campbell, Randy Strich

Stratford Campus Research Day

One of the largest and most dynamic tissues in the body, skeletal muscle, requires constant regeneration and upkeep. Dysregulation of this regeneration process has been implicated in many neuromuscular diseases and myotonic dystrophies. Regeneration requires the differentiation of myogenic lineages including exiting the cell cycle, gene expression changes, and fusing of myoblasts into multinucleate myotubes. Part of this reconstruction requires the breakdown and repopulation of mitochondrial networks. At the early onset of myoblast differentiation, there is an upregulation of dynamin-related protein, Drp1, and an increase in mitophagy mediated by sequestosome (SQSTM1) removal of mitochondria.

Previously, our lab has shown that …

A Puzzling Case Of Normal Pressure Hydrocephalus In The Outpatient Setting, Shadi Shams, Asim Shafique, Marym Khan, James Bailey

Stratford Campus Research Day

Normal Pressure Hydrocephalus (NPH) is a disease of adulthood characterized by the triad of gait disturbance, dementia, and urinary incontinence. Since NPH shares a lot of characteristics with other disorders including neurodegenerative disorders and degenerative-dystrophic spine, it is usually underdiagnosed and undertreated. Combination of ventriculomegaly seen on a computerized tomography (CT) scan or magnetic resonance imaging (MRI) with clinical findings could be used in diagnosis of NPH. However, improvement of symptoms post spinal tap procedure would be a better indication of diagnosis. Currently, shunt placement is the best available modality of treatment for NPH. Here we present a case of …

Plasmalogen Deficiency: A Risk Factor For Dementias And Potential Treatment Target, Mitchel A. Kling, Mallika Mendu, Rima F. Kaddurah-Daouk, Sheldon Jordan, Dayan B. Goodenowe

Stratford Campus Research Day

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 …
