Regional Microglia Are Transcriptionally Distinct But Similarly Exacerbate Neurodegeneration In A Culture Model Of Parkinson's Disease., Eric Wildon Kostuk, Jingli Cai, Lorraine Iacovitti

Department of Neuroscience Faculty Papers

BACKGROUND: Parkinson's disease (PD) is characterized by selective degeneration of dopaminergic (DA) neurons of the substantia nigra pars compacta (SN) while neighboring ventral tegmental area (VTA) DA neurons are relatively spared. Mechanisms underlying the selective protection of the VTA and susceptibility of the SN are still mostly unknown. Here, we demonstrate the importance of balance between astrocytes and microglia in the susceptibility of SN DA neurons to the PD mimetic toxin 1-methyl-4-phenylpyridinium (MPP

METHODS: Previously established methods were used to isolate astrocytes and microglia from the cortex (CTX), SN, and VTA, as well as embryonic midbrain DA neurons from the …

Objective: The purpose of this study was to assess if a novel combination of melatonin and three other natural bone-aiding micronutrients: strontium citrate, vitamins D₃ and K₂ (MSDK) could improve bone health by modulating the activity of osteoblasts and osteoclasts in favor of balanced bone remodeling and by improving the overall health-related quality of life in postmenopausal osteopenic women.

Methods: The Melatonin-micronutrients Osteopenia Treatment Study (MOTS) is a translational research study that used both clinical and in vitro approaches to assess the efficacy of MSDK on bone health in women and to identify potential mechanisms for its effects. …

Abrogation Of Transforming Growth Factor-Β-Induced Tissue Fibrosis In Tbricacol1a2cre Transgenic Mice By The Second Generation Tyrosine Kinase Inhibitor Ski-606 (Bosutinib)., Peter J. Wermuth, Sergio A. Jimenez

Jefferson Institute of Molecular Medicine Papers and Presentations

Transforming growth factor-β (TGF-β) plays a crucial role in the pathogenesis of Systemic Sclerosis (SSc) and other fibrotic disorders. TGF-β-mediated c-Abl and Src kinase activation induces strong profibrotic cascade signaling. The purpose of this study was to test in vivo the antifibrotic activity of Bosutinib (SKI-606), a second generation c-Abl and Src kinase inhibitor, on TGF-β induced cutaneous and pulmonary fibrosis. For this purpose, we employed the TBRIcaCol1a2Cre transgenic mice expressing an inducible constitutively active TGF-β receptor 1 constitutively activated by Col1a promoter-mediated Cre recombinase. The mice were treated parenterally with 2.5, 5.0 or 10.0 mg/kg/day of Bosutinib for 42 …

The Comparison Of Spectral Domain Optical Coherence Tomography (Sd-Oct) To Histopathology In A Patient With Diffuse Macular Drusen, Harold Salmons, Ralph Eagle, Md

Department of Pathology Honors Program Student Research Symposium

Background: Spectral Domain Optical Coherence Tomography (SD-OCT) has become a gold standard technique in ophthalmologic practice, and has revolutionized the diagnosis and treatment of retinal disease. As SD-OCT uses low interference interferometry and mathematical algorithms to produce detailed theoretical cross-sectional images of the retina, it is crucial to examine correlations between SD-OCT images and their corresponding histopathologic slides.

Methods: In the present study, careful correlative light microscopy was performed on the eye that was enucleated from an elderly patient who had a uveal melanoma and early agerelated macular degeneration evident clinically as soft drusen. SD-OCT was performed prior to enucleation …

The Use Of Liquid Biopsy In The Fight Against Cancer, Chamaka Kalutota, Emanual Rubin, Md

Department of Pathology Honors Program Student Research Symposium

In recent years, liquid biopsy has emerged as a potential alternative/adjunct to standard tissue biopsy in the diagnosis of malignancies. Current use of this technique, which tracks distinctive molecules released from neoplastic cells including circulating tumor cells (CTCs), exosomes, circulating tumor DNA (ctDNA), cell-free DNA (cfDNA) and miRNA, has generally been limited to determining therapies in lung cancer based on detectable mutations (EFGR, EML4-ALK). However, recent studies have demonstrated the possibility for using these molecules as more efficient prognostic and diagnostic biomarkers in breast, colon, rectum, lung, liver, and pancreatic cancer. Due to the need for standardization in sampled material …

Interferon-Gamma Impairs Maintenance And Alters Hematopoietic Support Of Bone Marrow Mesenchymal Stromal Cells, Marieke Goedhart, Anne S. Cornelissen, Carlijn Kuijk, Sulima Geerman, Marion Kleijer, Jaap D. Van Buul, Stephan Huveneers, Marc H.G.P. Raaijmakers, Howard A. Young, Monika C. Wolkers, Carlijn Voermans, Martijn A. Nolte

United States Public Health Resources

Bone marrow (BM) mesenchymal stromal cells (MSCs) provide microenvironmental support to hematopoietic stem and progenitor cells (HSPCs). Culture-expanded MSCs are interesting candidates for cellular therapies due to their immunosuppressive and regenerative potential which can be further enhanced by pretreatment with interferon-gamma (IFN-γ). However, it remains unknown whether IFN-γ can also influence hematopoietic support by BM-MSCs. In this study, we elucidate the impact of IFN-γ on the hematopoietic support of BM-MSCs. We found that IFN-γ increases expression of interleukin (IL)-6 and stem cell factor by human BM-MSCs. IFN-γ-treated BM-MSCs drive HSPCs toward myeloid commitment in vitro, but impair subsequent differentiation of …

Genome Editing Technology, Crispr Cas-9, Provides A Potential Future For Xenotransplantation: Can Pigs Become Our New Organ Donors?, Shelby Smith, Bs, Emanual Rubin, Md

Department of Pathology Honors Program Student Research Symposium

Organ shortage has been a significant issue in United States for many decades. There were over 116,000 people on the transplant waiting list as of August 2017, with a new person added every 10 minutes. Animals have been considered as potential organ donors for humans, with the pig being the most ideal candidate because of its excellent breeding profile, low maintenance costs, large litters, rapid growth and organ similarity. A notable challenge that comes with porcine organs are endogenous retroviruses that establish themselves in the DNA of offspring in utero, thereby allowing for no time to prevent infection and integration. …

Acquired Resistance Mutations To Egfr Treatment In Non-Small Cell Lung Cancer, Benjamen Schoenberg, Gregory Omerza, Phd

Department of Pathology Honors Program Student Research Symposium

Non-small cell lung cancer (NSCLC) is currently the number one cause of cancer death in the United States for both men and women.1 Mutations in the epidermal growth factor receptor (EGFR) gene are detected in approximately 30% of individuals with advanced NSCLC in Asia and 10-15% in Western countries.2 For patients harboring activating EGFR mutations, treatment includes the use of first or second-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs), such as afatinib, gefitinib, or erlotinib.

The purpose of this case study is to review the pathophysiology of the progression of NSCLC in a 63-year-old non-smoking Caucasian woman. The patient presented with worsening …

A New Frontier In Breast Cancer Management: Oncotype Dx, Gabriella Rollo, Jeremy Molligan, Md, Juan P. Palazzo, Md

Department of Pathology Honors Program Student Research Symposium

Diagnosing and prognosticating breast cancer has traditionally relied upon histomorphologic analysis and immunohistochemistry. With the recent advent of multigene molecular assays, traditional methods are being augmented with molecular biomarkers. Implementation of the Oncotype DX assay has led to a change in treatment of patients with early stage, estrogen positive cancer. Oncotype DX uses the expression of 21 genes at the mRNA level to determine a 10 year recurrence risk in node negative and 5 year recurrence risk in node positive cancer. 16 malignancy markers related to estrogen, HER2, cell proliferation, and invasion potential are compared with 5 reference genes and …

Primary Cns Small Mature B-Cell Lymphoma With Plasmacytic Differentiation Presenting As An Amyloidoma: A Case Report And Review Of Literature, Andrew Lynch, Geetha Jagannathan, Md

Department of Pathology Honors Program Student Research Symposium

Primary central nervous system lymphomas (PCNSL) without systemic involvement are rare and account for only 2-3% of all brain tumors and <1% of all non-Hodgkin’s lymphoma (NHL). Close to 40% of PCNSL are associated with immunosuppression, however, the incidence of primary central nervous system (CNS) lymphomas has shown an increasing trend in immunocompetent patients in recent decades due to better control of HIV and drug-induced immunosuppression [2]. Here, we describe a case of a primary CNS non-Hodgkin’s small mature B-cell lymphoma with plasmacytic differentiation in an immunocompetent individual. A previously healthy 87-year-old Caucasian woman presented to the neurology clinic with complaints of slowly progressing left sided weakness, predominantly in the left arm and leg over the last 6 months. Magnetic resonance imaging of the brain revealed a large, confluent white matter T2-hyperintensity in the right frontal lobe with multifocal nodular enhancement involving the left cerebral hemisphere, cerebellum, and leptomeninges, consistent morphologically with lymphoplasmacytic lymphoma. A bone marrow biopsy showed normal trilineage hematopoiesis with no evidence of lymphoma, myeloma or amyloidosis. Our patient was treated with Rituximab but developed an ischemic infarct of the left frontal white matter. She and her family decided to forego further treatment and switch to hospice care.

Ewing’S Sarcoma, Chris Lucasti, Bs, Bruce A. Fenderson, Phd

Department of Pathology Honors Program Student Research Symposium

Ewing’s sarcoma is the second most common malignant tumor of the bone occurring in children and adolescents. Typically, patients present between the ages of 10 and 20, with the disease having a slight predilection for males.1 Tumors often arise in the mid-shaft with the femur being the most frequently affected bone. The most common chromosome translocation, t(11;22)(q24;q12), occurs between the EWS gene and the FLI-1 gene. This translocation has been implicated in these aggressive and malignant tumors.1–4 Oftentimes, patients present with pain and swelling in the area of the affected bone or joint.5 While there has been some improvement in …

Clinico-Pathological Features And Pd-1/Pd-L1 Expression In Primary Mediastinal Large B Cell Lymphoma, Lydia Glick, Geetha Jagannathan, Md, Guldeep Uppal, Md

Department of Pathology Honors Program Student Research Symposium

Primary Mediastinal Large B Cell Lymphoma (PMBCL) is a distinct subtype of Diffuse Large B Cell Lymphoma (DLBCL) that has been historically reported to have a worse prognosis than DLBCL. Occasional studies have reported PD-L1 expression in PMBCL, which can emerge as an important target for immune-check point therapy. This study aimed to evaluate clinico-pathological features and characterize the expression of PD-1 and PD-L1 in a single cohort of 15 patients with PMBCL.

A total of 15 cases of PMBCL were retrieved from records of the department of Pathology; eleven of these had tissue available for additional immunohistochemistry, specifically, PD-L1 …

Comparative Analysis Of Tumor Capsule Thickness And Other Histologic Features In Encapsulated Follicular Variant Of Papillary Thyroid Carcinoma (Efvptc) And Noninvasive Follicular Thyroid Neoplasm With Papillary-Like Nuclear Features (Niftp), Brenda French, Stacey K. Mardekian, Md

Department of Pathology Honors Program Student Research Symposium

Recent reclassification of a subset of non-invasive encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC) tumors as non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) has led to important changes in the clinical management of patients with these indolent lesions. Although there are established diagnostic criteria to differentiate NIFTP from EFVPTC, our objective was to determine further differences in histological characteristics between NIFTP and noninvasive EFVPTC. Additionally, we sought to identify histological differences between non-invasive and invasive EFVPTC lesions beyond the key finding of invasion. 68 encapsulated follicular lesions with papillary-like nuclear features from patients treated at Thomas Jefferson …

Implications Of Hobnail Features In Anaplastic Thyroid Carcinoma And Precursor Lesions, Caroline Dunne, Ba, Stacey K. Mardekian, Md

Department of Pathology Honors Program Student Research Symposium

Anaplastic thyroid carcinoma (ATC) has the poorest prognosis of all thyroid cancers. Morphologically, it is characterized by pleomorphic undifferentiated cells. In some cases, a differentiated precursor lesion, either papillary thyroid carcinoma (PTC) or follicular thyroid carcinoma, can be identified adjacent to the anaplastic component. There are certain morphological variants of PTC that are known to be associated with more aggressive behavior, but a recently described, understudied variant is the hobnail variant. It is characterized histologically by micropapillary structures lined by cells with abundant eosinophilic cytoplasm and apically-placed bulging nuclei. The aim of this study was to evaluate the frequency of …

Atypical Presentation Of Upshaw Schulman Syndrome: A Case Report, Goutham Ravipati, Bs, David Strayer, Md, Phd, Douglas Drelich, Md

Department of Pathology Honors Program Student Research Symposium

Thrombotic thrombocytopenic purpura (TTP) is a rare coagulation disorder with a typical clinical presentation of low platelets and excessive clotting. Mortality for this disorder may be high if untreated and therefore necessitates a high clinical suspicion. Here we describe a 46-year-old African American woman with a past medical history of multiple cerebrovascular accidents presenting to hematology after a suspected diagnosis of TTP. Presumptive diagnosis of acquired TTP called for treatment with IVIg, but a diagnosis of congenital TTP (Upshaw Schulman syndrome) was made after testing showed a lack of ADAMTS13 antibodies. Treatment with fresh frozen plasma (FFP) showed increase in …

Synaptic Nanomodules Underlie The Organization And Plasticity Of Spine Synapses., Martin Hruska, Nathan T. Henderson, Sylvain J. Le Marchand, Haani Jafri, Matthew B. Dalva

Department of Neuroscience Faculty Papers

Experience results in long-lasting changes in dendritic spine size, yet how the molecular architecture of the synapse responds to plasticity remains poorly understood. Here a combined approach of multicolor stimulated emission depletion microscopy (STED) and confocal imaging in rat and mouse demonstrates that structural plasticity is linked to the addition of unitary synaptic nanomodules to spines. Spine synapses in vivo and in vitro contain discrete and aligned subdiffraction modules of pre- and postsynaptic proteins whose number scales linearly with spine size. Live-cell time-lapse super-resolution imaging reveals that NMDA receptor-dependent increases in spine size are accompanied both by enhanced mobility of …

Human Gucy2c-Targeted Chimeric Antigen Receptor (Car)-Expressing T Cells Eliminate Colorectal Cancer Metastases., Michael S. Magee, Tara S. Abraham, Trevor R. Baybutt, John C. Flickinger, Natalie A. Ridge, Glen P Marszalowicz, Priyanka Prajapati, Adam R. Hersperger, Scott A. Waldman, Adam E. Snook

Department of Pharmacology and Experimental Therapeutics Faculty Papers

One major hurdle to the success of adoptive T-cell therapy is the identification of antigens that permit effective targeting of tumors in the absence of toxicities to essential organs. Previous work has demonstrated that T cells engineered to express chimeric antigen receptors (CAR-T cells) targeting the murine homolog of the colorectal cancer antigen GUCY2C treat established colorectal cancer metastases, without toxicity to the normal GUCY2C-expressing intestinal epithelium, reflecting structural compartmentalization of endogenous GUCY2C to apical membranes comprising the intestinal lumen. Here, we examined the utility of a human-specific, GUCY2C-directed single-chain variable fragment as the basis for a CAR construct targeting …

Determining The Role Of Point-Of-Care Hemoglobin Testing In The Resuscitation Of Acutely Hemorrhaging Patients, Eugene P. Warnick, Alexis R. Peedin, Md

Department of Pathology Honors Program Student Research Symposium

Point-of-care hemoglobin (Hb) testing has not been evaluated in the resuscitation of acutely hemorrhaging patients to guide transfusion therapy. This study assessed the correlation of Hb values determined by point-of-care (EPOC) and traditional laboratory (CBC) methods in patients undergoing massive transfusion. All patients transfused per the massive transfusion protocol (MTP) between February 2013 and October 2017 were identified. The EPOC result was most often within 1 g/dL of the CBC result when EPOC resulted in a Hb between 7-10 g/dL and when drawn within 15 minutes of the CBC specimen. In patients on MTP with an EPOC Hb between 7-10 …

Metastatic Lobular Breast Carcinoma In A Meningioma: A Case Study, Sara Chapin, Msii, Lawrence C. Kenyon, Md, Phd

Department of Pathology Honors Program Student Research Symposium

Hormonal relationships between breast carcinoma and meningioma have long been reported in the literature. This association may be related to the widespread expression of progesterone receptors in meningiomas. Indeed, meningiomas are more common in women and may demonstrate increased growth during pregnancy. Women have an increased risk of meningioma following breast carcinoma diagnosis and vice versa. However, much more uncommon is a tumor to tumor metastases of breast carcinoma into a meningioma. We report a case of a 56 year old female with a past medical history of breast cancer, found to have a right sphenoorbital meningioma with metastatic lobular …

Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

Social rejection is a painful event that often increases aggression. However, the neural mechanisms of this rejection–aggression link remain unclear. A potential clue may be that rejected people often recruit the ventrolateral prefrontal cortex’s (VLPFC) self-regulatory processes to manage the pain of rejection. Using functional MRI, we replicated previous links between rejection and activity in the brain’s mentalizing network, social pain network and VLPFC. VLPFC recruitment during rejection was associated with greater activity in the brain’s reward network (i.e. the ventral striatum) when individuals were given an opportunity to retaliate. This retaliation-related striatal response was associated with greater levels of …

Intestinal Permeability And Microbial Dysbiosis In Acute Coronary Syndrome (Miacs Study), Tarik Z. Alhmoud

Biomedical Sciences ETDs

Background: Acute Coronary Syndrome (ACS) is a leading cause of morbidity and mortality. Metabolic syndrome and obesity are major risk factors for atherosclerosis and ACS. Dysbiosis plays an important role in metabolic syndrome and obesity. Studies show a markedly increased risk of heart attacks in patients with high levels of the pro-atherogenic metabolite trimethylamine-N-Oxide (TMAO). TMAO is produced by the intestinal microbial flora through metabolism of dietary phospholipids; Gram-negative bacteria (Phylum Proteobacteria) is the major source of TMAO metabolism. Patients with obesity and metabolic syndrome have a defective intestinal tight-junctional (TJ) barrier, which allows paracellular permeation of luminal antigens such …

Three Speeds Of Yoga And The Effects On Salivary Cortisol Levels In Female Nursing Students, Meagan Hennekens

All NMU Master's Theses

Purpose: Nursing students are prone to stress-related diseases, such as depression and anxiety, which are associated with chronically elevated cortisol levels due to the excessive firing of the Hypothalamic Pituitary Adrenal (HPA) axis. This study assessed three speeds of yoga and how they acutely affected salivary cortisol levels within female nursing students. Methods: Students participated in three yoga sessions cadenced at different speeds in a non-randomized order: (i) standard-speed yoga (SSY), (ii) high-speed yoga (HSY), and (iii) slow-speed yoga (SLSY). Each class integrated sequencing concepts from the brahmana/langhana strategy (BLS) and the Para Yoga Blueprint (PYB). Cortisol samples were …

Finding Small-Bowel Lesions: Challenges In Endoscopy-Image-Based Learning Systems, Jungmo Ahn, Loc Nguyen Huynh, Rajesh Krishna Balan, Youngki Lee, Jeonggil Ko

Research Collection School Of Computing and Information Systems

Capsule endoscopy identifies damaged areas in a patient's small intestine but often outputs poor-quality images or misses lesions, leading to either misdiagnosis or repetition of the lengthy procedure. The authors propose applying deep-learning models to automatically process the captured images and identify lesions in real time, enabling the capsule to take additional images of a specific location, adjust its focus level, or improve image quality. The authors also describe the technical challenges in realizing a viable automated capsule-endoscopy system.

Otologic Blast Injuries, Michelle Singer

Dissertations, Theses, and Capstone Projects

The otologic system functions as a highly sensitive pressure transducer. Because of this, the ear is the most commonly affected organ in primary blast injury. Frequently encountered symptoms include hearing loss, tinnitus, and tympanic membrane perforations. The ear is repeatedly overlooked during triage and easily forgotten in subjects with multiple injuries after major catastrophic events such as explosions. This systematic review provides an overview of the most common otologic injuries observed after blast exposure in a variety of settings and populations. An analysis of 35 studies and an additional 23 reviews was performed in attempt to uncover patterns of otologic …

Common Ribs Of Inhibitory Synaptic Dysfunction In The Umbrella Of Neurodevelopmental Disorders, Rachel Ali Rodriguez, Christina Joya, Rochelle M. Hines

Psychology Faculty Research

The term neurodevelopmental disorder (NDD) is an umbrella term used to group together a heterogeneous class of disorders characterized by disruption in cognition, emotion, and behavior, early in the developmental timescale. These disorders are heterogeneous, yet they share common behavioral symptomatology as well as overlapping genetic contributors, including proteins involved in the formation, specialization, and function of synaptic connections. Advances may arise from bridging the current knowledge on synapse related factors indicated from both human studies in NDD populations, and in animal models. Mounting evidence has shown a link to inhibitory synapse formation, specialization, and function among Autism, Angelman, Rett …

Cd8+ T-Cell Responses In Vaccination: Reconsidering Targets And Function In The Context Of Chronic Antigen Stimulation, Gabriela L. Cosma, Laurence Eisenlohr

Department of Microbiology and Immunology Faculty Papers

Cytotoxic CD8 T cells play important roles in eliminating infected and transformed cells. Owing to their potential for therapeutic applications, significant efforts are dedicated toward developing CD8 T cell-based vaccines. Thus far, CD8 T-cell vaccination strategies have had limited success therapeutically in contrast to those targeting antibody-based immunity. However, if the current challenges and gaps in the understanding of T-cell biology are overcome, the full potential of rational CD8 T-cell vaccine design might be realized. Here, we review recent progress in this direction, focusing on target selection and maintenance of function in the settings of chronic infections and cancers.

Identifying What Matters To Hysterectomy Patients: Postsurgery Perceptions, Beliefs, And Experiences, Andrew S. Bossick, Roopina Sangha, Heather Olden, Gwen L. Alexander, Ganesa Wegienka

Journal of Patient-Centered Research and Reviews

Purpose: Hysterectomy is the most common nonobstetrical surgery for women in the United States. Few investigations comparing hysterectomy surgical approaches include patient-centered outcomes.

Methods: The study was performed at Henry Ford Health System (Detroit, MI) between February 2015 and May 2015. A total of 1,038 eligible women — those 18 to 65 years of age and who had an electronic medical record-documented Current Procedural Terminology (CPT^®) code or an International Statistical Classification of Diseases, Ninth Edition (ICD-9) code of hysterectomy between December 2012 and December 2014 — were selected and recruited. A question guide was developed to investigate …

Epigenetic Regulation Of Tumor Suppressors By Helicobacter Pylori Enhances Ebv-Induced Proliferation Of Gastric Epithelial Cells, Saurabh Pandey, Hem Chandra Jha, Sanket Kumar Shukla, Meghan K. Shirley, Erle S. Robertson

Department of Medicine Faculty Papers

Helicobacter pylori and Epstein-Barr virus (EBV) are two well-known contributors to cancer and can establish lifelong persistent infection in the host. This leads to chronic inflammation, which also contributes to development of cancer. Association with H. pylori increases the risk of gastric carcinoma, and coexistence with EBV enhances proliferation of infected cells. Further, H. pylori-EBV coinfection causes chronic inflammation in pediatric patients. We have established an H. pylori-EBV coinfection model system using human gastric epithelial cells. We showed that H. pylori infection can increase the oncogenic phenotype of EBV-infected cells and that the cytotoxin-associated gene (CagA) protein encoded by H. …
