Cortical Demyelination And Depression-Like Behavior Are Associated With Histaminergic Dysregulation In A Mouse Model Of Peripheral Inflammation, Danielle Germundson-Hermanson

Biomedical Sciences Posters and Presentations

▪ Demyelinating diseases of the central nervous system are increasing in prevalence world-wide1,2 and manifest as motor, behavioral, and/or cognitive defects3 . The etiology and pathophysiology of demyelinating diseases remain unclear.

▪ We have previously observed cortical demyelination in our mouse model of non-anaphylactic cow’s milk allergy4 . The demyelination was associated with depression-like behaviors and region-specific increases in brain histamine and H3 receptor (H3R) levels4,5 .

❖ The brain’s central histaminergic system is tightly controlled and regulates many behaviors. Additionally, signaling through H3R plays a crucial role in oligodendrocyte differentiation, and thus, demyelination and remyelination6 .

▪ We hypothesized …

Journal Articles: Pathology and Microbiology

Clostridium novyi has demonstrated selective efficacy against solid tumors largely due to the microenvironment contained within dense tumor cores. The core of a solid tumor is typically hypoxic, acidic, and necrotic-impeding the penetration of current therapeutics. C. novyi is attracted to the tumor microenvironment and once there, can both lyse and proliferate while simultaneously re-activating the suppressed immune system. C. novyi systemic toxicity is easily mitigated by knocking out the phage DNA plasmid encoded alpha toxin resulting in C. novyi-NT; but, after intravenous injection spores are quickly cleared by phagocytosis before accomplishing significant tumor localization. C. novyi-NT could be designed …

Journal Articles: Pathology and Microbiology

Background: Cerebrospinal fluid (CSF) shunt infection is a common and devastating complication of the treatment of hydrocephalus. Timely and accurate diagnosis is essential as these infections can lead to long-term neurologic consequences including seizures, decreased intelligence quotient (IQ) and impaired school performance in children. Currently the diagnosis of shunt infection relies on bacterial culture; however, culture is not always accurate since these infections are frequently caused by bacteria capable of forming biofilms, such as Staphylococcus epidermidis, Cutibacterium acnes, and Pseudomonas aeruginosa resulting in few planktonic bacteria detectable in the CSF. Therefore, there is a critical need to identify a …

Journal Articles: Pathology and Microbiology

Bone metastatic disease of prostate cancer (PCa) is incurable and progression in bone is largely dictated by tumor-stromal interactions in the bone microenvironment. We showed previously that bone neutrophils initially inhibit bone metastatic PCa growth yet metastatic PCa becomes resistant to neutrophil response. Further, neutrophils isolated from tumor-bone lost their ability to suppress tumor growth through unknown mechanisms. With this study, our goal was to define the impact of metastatic PCa on neutrophil function throughout tumor progression and to determine the potential of neutrophils as predictive biomarkers of metastatic disease. Using patient peripheral blood polymorphonuclear neutrophils (PMNs), we identified that …

Advances In Antimicrobial Peptide Discovery Via Machine Learning And Delivery Via Nanotechnology, Alexa Sowers, Guangshun Wang, Malcolm Xing, Bingyun Li

Journal Articles: Pathology and Microbiology

Antimicrobial peptides (AMPs) have been investigated for their potential use as an alternative to antibiotics due to the increased demand for new antimicrobial agents. AMPs, widely found in nature and obtained from microorganisms, have a broad range of antimicrobial protection, allowing them to be applied in the treatment of infections caused by various pathogenic microorganisms. Since these peptides are primarily cationic, they prefer anionic bacterial membranes due to electrostatic interactions. However, the applications of AMPs are currently limited owing to their hemolytic activity, poor bioavailability, degradation from proteolytic enzymes, and high-cost production. To overcome these limitations, nanotechnology has been used …

Medical Professionals’ Perspective On Safety And Efficacy Of Early Mobilization In Acute Heart Failure Patients, Kevin Triangto, Febrian M. Santausa, Basuni Radi, Bambang Budi Siswanto

Journal of the Hong Kong College of Cardiology

Acute heart failure (HF) patients most of the time presents with hemodynamic instability, which often leads to prolonged bedrest. Newer studies had shown that early mobilization for HF patients would lead to better outcomes. However, the early mobilization practice has not always been done due to several barriers in the medical professionals’ perspective, especially regarding safety and efficacy. Prior studies had shown that medical professionals’ views would greatly affect patients’ perspectives, especially in HF rehabilitation. This study is aimed to describe medical professionals’ views on the safety of early mobilization for HF. It was then revealed that General Practitioners’ (GP) …


Examining A Blood Biomarker Approach To Blood-Brain Barrier Disruption, Samantha Ford Jan 2023

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 …

Brain functional networks identified from resting functional magnetic resonance imaging (fMRI) data have the potential to reveal biomarkers for brain disorders, but studies of complex mental illnesses such as schizophrenia (SZ) often yield mixed results across replication studies. This is likely due in part to the complexity of the disorder, the short data acquisition time, and the limited ability of the approaches for brain imaging data mining. Therefore, the use of analytic approaches which can both capture individual variability while offering comparability across analyses is highly preferred. Fully blind data-driven approaches such as independent component analysis (ICA) are hard to …

Faculty, Staff and Student Publications

Alzheimer's disease (AD) and other classes of dementia are important public health problems with overwhelming social, physical, and financial effects for patients, society, and their families and caregivers. The pathophysiology of AD is poorly understood despite the extensive number of clinical and experimental studies. The brain's lipid-rich composition is linked to disturbances in lipid homeostasis, often associated with glucose and lipid abnormalities in various neurodegenerative diseases, including AD. Moreover, elevated low-density lipoprotein (LDL) cholesterol levels may be related to a higher probability of AD. Here, we hypothesize that lipids, and electronegative LDL (L5) in particular, may be involved in the …

Background and objective: Whole body manipulation of the renin-angiotensin system (RAS) consistently exerts profound effects on experimental atherosclerosis development. A deficit in the literature has been a lack of attention to the effects of sex. Also, based on data with gene-deleted mice, the site of RAS activity that influences lesion formation is at an unknown distant location. Since angiotensin (AngII) concentrations are high in kidney and the major components of the RAS are present in renal proximal tubule cells (PTCs), this study evaluated the role of the RAS in PTCs in atherosclerosis development.

Methods and results: Mice with an LDL …


Parental Instincts: The Neurological And Biological Factors Associated With Parenthood, Jared Reeder Jan 2023

Parental Instincts: The Neurological And Biological Factors Associated With Parenthood, Jared Reeder

Undergraduate Honors Theses

The following project involves a systematic review of the scientific literature on neural and biological changes of mothers and fathers in parenthood. Until very recently, little scientific research was devoted to studying how bearing children affects a man or woman’s long-term biology. Over the last twenty years, studies of neuroplastic changes in new mothers show specific neural mechanisms responsible for altering the behaviors of mothers during and after pregnancy. These changes in neuroplasticity alter behavior in such a way that led to mothers requiring less sleep and being more prone to hearing the cries of their children. In addition to …

Copy Number Alterations Of Aggressive Pituitary Neuroendocrine Tumors, Grace Zhang Jan 2023

Copy Number Alterations Of Aggressive Pituitary Neuroendocrine Tumors, Grace Zhang

Scripps Senior Theses

Pituitary neuroendocrine tumors (PitNETs) are tumors of the pituitary gland. Although most are benign, they can cause severe morbidity if compression of surrounding tissue and/or endocrinopathies occur.

Aggressive PitNETs are notably detrimental and difficult to predict, and their effects are further exacerbated by challenges in treatment. Although histological studies can detect certain markers of tumor aggressiveness, they are insufficient at wholly predicting PitNET aggressiveness, making the clinical behavior of PitNETs challenging to determine. Since treatment of aggressive tumors also remains suboptimal, this further results in negative impacts on health and quality of life.

Genetic markers, such as copy number variations …

Visualization And Characterization Of The Immunological Synapse Between Chlorotoxin Chimeric Antigen (Cltx-Car) Redirected T Cells And Targeted Glioblastoma Tumors, Arianna Livi

CMC Senior Theses

Chimeric Antigen Receptor T (CAR-T) cells have demonstrated anti-tumor activity against aggressive and invasive cancers such as glioblastoma (GBM); however, clinical response rates remain low in clinical trial studies. Tumor heterogeneity and tumor microenvironment conditions pose significant challenges for treatment of GBM, thus continuous optimization of CAR-T cell therapies and identification of novel, widely expressed, and highly specific GBM antigens are vital to better patient outcomes. A newly developed CAR-T cell construct incorporating chlorotoxin (CLTX) as the targeting domain exhibited broad GBM-targeting capabilities and elicited potent cytotoxic effects during preclinical studies and is currently being tested in a phase I …


High Cholesterol Diet Induces Sudden Death In Mice With Impaired Reverse Cholesterol Transport, Misa Ito Jan 2023

High Cholesterol Diet Induces Sudden Death In Mice With Impaired Reverse Cholesterol Transport, Misa Ito

Theses and Dissertations--Pharmacology and Nutritional Sciences

Unexplained sudden death continues to be a major public health crisis as AHA reports that 1,000 people suffer sudden cardiac arrest each day in the U.S. with only 10% surviving. A number of ongoing challenges hinder to understand the sudden death. Thus, investigating underlined mechanisms of sudden death is urgent. Unexpectedly, I found a high cholesterol diet (HCD)-induced sudden death preclinical model. Although HCD is associated with a higher risk of cardiovascular disease (CVD) and the subendothelial lipoprotein retention theory is well established for atherosclerosis development, these theories cannot explain the sudden death in my model because atherosclerosis and CVD …
