Julie Saugstad, PhD

CO-CHAIR: Julie Saugstad, PhD. Professor, Department of Anesthesiology & Perioperative Medicine, Affiliate Faculty, Department of Molecular & Medical Genetics
Oregon Health & Sciences University

PhD, 1991, Biochemistry & Molecular Biology
University of Oklahoma Health Sciences Center

Dr. Saugstad cloned the genes for mouse metabotropic glutamate receptors 7 and 8 (mGluRs), then studied the regulation of signaling by mGluRs. Her lab was the first to show that miRNAs are differentially regulated by ischemic preconditioning in mouse brain, and the first to show a miRNA signature common to males and females in stroke, and conversely that distinct miRNAs are regulated by stroke in male vs. female mouse brain. Her studies were also the first to identify miRNAs that discriminate Alzheimer’s disease (AD) from controls in cerebrospinal fluid (CSF) from living donors, that combinations of miRNAs serve as sensitive and specific biomarkers for AD, that adding a reference marker (such as APOEɛ4 genotype) and CSF Aβ42:T-Tau ratios to miRNA combinations increases classification performance for AD, and that a subset of miRNAs show a linear trend of decreasing median expression from controls to mild cognitive impairment to AD. Her current studies have shown that the AD miRNAs in CSF work better to discriminate AD from controls in plasma, and her studies have now expanded to include the role(s) of extracellular vesicles and their cargo in AD and neurodegenerative diseases.

Research Interests: Cellular and molecular mechanisms of signaling in the brain; Role of microRNAs in CSF and plasma as AD biomarkers; Contribution of EVs and their cargo as mediators of intercellular communication and their potential role in altered signaling in dementia.

Dr. Sultana received postdoctoral training in vector-borne diseases at Yale University School of Medicine and the Howard Hughes Medical Institute. She was promoted to Associate Research Scientist after receiving an independent RO3 award from NIH/NIAID to study tick-pathogen interactions. In 2010, she obtained a tenure-track assistant professor position at the Center for Molecular Medicine, Department of Biological Sciences, Old Dominion University (ODU) and in 2012, she received tenure and promotion to associate professor at ODU. Her research is in the field of vector-borne diseases where she laid the foundation for novel investigations on arthropod exosomes in facilitating transmission of tick and mosquito-borne flaviviruses from vector to the vertebrate host. Her laboratory was the first to provide evidence that tick/mosquito-borne flaviviruses use arthropod-derived exosomes for transmission of full-length RNA genomes, proteins/poly-proteins from vector to the mammalian cells and that these viruses use exosomes for dissemination within the vertebrate host. She has received R01 funding from NIH/NIAID to continue this line of research on arthropod exosomes.

GRANT-FUND COMMITTEE

Ursula Saundau, PhD, Instructor
Oregon Health & Science University

PhD, 2006, Biomedical Neuroscience
Colorado State University

Dr. Sandau studies the role of extracellular vesicle miRNAs as biomarkers for and mediators of neurological dysfunction in Alzheimer’s disease. She has identified a set of extracellular vesicle miRNAs in human cerebrospinal fluid (CSF) with increased expression in Alzheimer’s disease. These miRNAs are predicted to repress the translation of proteins integral to synaptic transmission via their roles in presynaptic neurotransmitter release and postsynaptic NMDA receptor trafficking and signaling. Her current studies are aimed to demonstrate that in Alzheimer’s disease the miRNAs increased in CSF extracellular vesicles are also increased in the brain and relate to abnormal synapse formation. She also has a collaboration with the Oregon Health & Science University Methamphetamine Research Center to investigate the potential of plasma extracellular vesicles and their miRNA cargo to serve as biosignatures for neuropsychiatric impairments that occur in addiction and impede recovery.  

Research Interests: Alzheimer’s disease; Extracellular vesicles; MiRNAs; Synaptic plasticity and transmission
