Tau accumulates in a group of neurodegenerative diseases known as tauopathies. A prevailing hypothesis has been that Tau degradation is impaired due to an age-related imbalance in the autophagy-lysosome pathway, but whether these defects are a cause or consequence of Tau accumulation remains unclear. Here we show that a disease-causing mutation in the MAPT gene, which encodes Tau, p.R406W, is sufficient to disrupt multiple steps of the autophagy-lysosome pathway in human neurons. Using Airyscan super-resolution imaging, we find that mutant Tau neurons accumulate Tau and phosphorylated Tau in dysfunctional lysosomes, exhibit reduced lysosome motility, impaired fusion of autophagosomes and lysosomes, …

Ketone bodies have traditionally been recognized as glucose-sparing energy sources, with hepatic ketogenesis and peripheral ketolysis serving pivotal functions in maintaining energy homeostasis during fasting. Although they are commonly seen as harmful due to their link with ketoacidosis, recent studies emphasize their roles in organ protection. This has sparked interest in their possible use as a treatment for chronic kidney disease (CKD). In this study, we examined both exogenous and endogenous ketone body supplementation in adenine-induced kidney injury in mice. Supplementation with the ketone body precursor 1,3-butanediol significantly improved adenine-induced renal fibrosis, inflammation, and apoptotic cell death. However, genetically deleting …

Sulfatase Modifying Factors Control The Timing Of Zebrafish Convergence And Extension Morphogenesis, Ailen Soledad Cervino, Amrita Basu, Ryan J Weiss, Gursimran Kaur Bajwa, Rubén Marín-Juez, Sandra L Grimm, Cristian Coarfa, Margot Kossmann Williams

Faculty, Staff and Students Publications

Convergence and extension (C&E) cell movements that elongate the primary embryonic axis are precisely timed during vertebrate gastrulation, but mechanisms controlling their onset remain unknown. Using zebrafish embryonic explants that recapitulate C&E and its timing, we identified sulfatase modifying factor 2 (sumf2) as a candidate trigger gene for C&E onset. sumf2 and its paralog sumf1 encode negative and positive sulfatase regulators, respectively, whose expression levels invert and increase heparan sulfate sulfation during gastrulation. Overexpressing sumf1 or sumf2 causes delayed or precocious C&E, respectively, whereas their loss shifts C&E timing in the opposite direction. We identified Sulf1, a modifier of heparan …

Faculty, Staff and Students Publications

Background: Clearance of Plasmodium falciparum infection requires a TH1 immune response with production of pro-inflammatory cytokines, IgG1, and IgG3 responses. In contrast, infections with helminths are dominated by TH2/Treg immune responses characterized by production of anti-inflammatory cytokines, IgE, and IgG4, which could potentially interfere with malaria outcomes and immune responses.

Methods: We recruited 441 malaria-symptomatic children aged 2-10 years attending two hospitals in the Manhiça District (Mozambique) and assessed infection by rapid antigen diagnostic test, microscopy, and/or quantitative PCR. Using Luminex, we measured concentrations of 30 cytokines and IgA, IgM, IgE, IgG, and IgG1-4 levels against 12 P. falciparum antigens …

Falls In Inpatient Hospital Settings, Merlina Constantine

Walden Dissertations and Doctoral Studies

Inpatient falls are a common and preventable problem that affects health care costs, patient safety, and clinical quality. Inpatient falls occur within hospitals, cause harm, extend hospitalization, and require additional healthcare funding. Falls harm a patient’s physical health and cause emotional trauma, decrease patient satisfaction, and undermine confidence in the hospital care systems. Falls are therefore a significant concern in the nursing practice environment because nurses form the first component of prevention, monitoring, and intervention. This doctoral project aimed to re-educate and reinforce staff understanding of clinical guidelines to prevent inpatient falls through evidence-based interventions targeting environmental, behavioral, and organizational …

Ribosomal Stress In The Pathogenesis And Treatment Of T-Cell Acute Lymphoblastic Leukemia, Kimberly Bridget Johansson

Arts & Sciences Graduate Student Theses and Dissertations

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignancy in which activating mutations in the Notch pathway are thought to contribute to transformation, in part, through activation of c-Myc. Increased expression of c-Myc induces oncogenic stress that can lead to apoptosis through the Mdm2-p53 tumor suppressor pathway. Since the great majority of T-ALL cases maintain wildtype MDM2 and TP53, we hypothesized that T-ALL cells are selectively sensitive to MDM2 inhibition. Treatment with idasanutlin, an MDM2 inhibitor, although only inducing modest apoptosis in T-ALL cells, resulted in a significant upregulation of pro-apoptotic BH3 domain genes BAX and BBC3. This prompted …
