Allorecognition, parasitic stem cells and regeneration in a basal chordate
Abstract Our lab works at the intersection of immunology, stem cell biology and regeneration, and the grants funding this work (GM123267 and GM 123255) which we are requesting to m...
Understanding and leveraging molecular diversity within the phytochrome superfamily
Understanding and leveraging molecular diversity within the phytochrome superfamily. Our proposal focuses on the phytochrome superfamily of photoreceptors. We have a longstanding i...
Retooling innate immunity: An investigation of TLR-mediated glial priming across lifespan
This proposal examines how a novel TLR glial signaling pathway drives phagocytic competence in glia, and defines its function in pruning neuronal number and connectivity across lif...
Developmental underpinnings of substantia nigra vulnerability
Abstract: DA neuron degeneration, resulting in deficient DA signaling, underpins the debilitating motor symptoms of Parkinson’s disease (PD). Among DA neurons, those located in ven...
Experience-dependent Cellular Plasticity Mechanisms
Brain activity is essential for the development and plasticity of neurons and circuits, however our understanding of the mechanisms by which activity generates functional circuits...
Using nicotine to reverse age-related auditory processing deficits
Age-related decline in central auditory function significantly affects quality of life in the elderly, with impaired speech perception leading to increased risk for depression, soc...
Novel gastrocnemius muscle characteristics in peripheral artery disease patients associated with impaired functional performance
Lower extremity peripheral artery disease (PAD) significantly affects aging populations and results in functional impairment. Although the clinical importance of finding efficaciou...
Molecular mechanisms of Werner syndrome helicase in genome stability and aging
PROJECT SUMMARY Progeroid syndromes mimic aging at an accelerated rate and are key to understanding both premature and normal aging. One class of progeroid syndromes results from d...
hiPS cells derived skeletal muscle progenitors and their extracellular vesicles for treatment of sarcopenia
PROJECT SUMMARY Aging of skeletal muscle results in sarcopenia. It is believed that sarcopenia is in part due to a decreased capacity of stem cells, namely satellite cells, to repa...
Model Based Deep Learning Framework for Ultra-High Resolution Multi-Contrast MRI
Sensitive imaging biomarkers are urgently needed for screening of high‐risk subjects, determine early disease progression, and assess response to therapies in neurodegenerative dis...
Understanding the Cardiac Benefits of Exercise at the Cellular and Molecular Level
Project Summary/Abstract Heart failure (HF) is a growing cause of morbidity and mortality. Despite the best available treatments, prognosis remains poor for many HF patients unders...
Strategic Molecular Activations for the Selective Synthesis of 2-Deoxy-Beta-Glycosides, and for the Synthesis of Novel Donor-Acceptor Stenhouse Adducts
Project Summary/Abstract This proposal describes the use of fundamental chemical properties to alter the reactivity of reagents for the synthesis of biomedically important compound...
Boston Latino Aging Study (BLAST): Understanding Alzheimer's risk and biomarkers in older Latinos
Latinos are the fastest growing subpopulation of older adults in the U.S.A. and have a greater prevalence of Alzheimer’s disease (AD) than non-Latino whites (1). Despite this, our...
Small Molecule KLF15 Agonists for Kidney Disease
The Centers for Disease Control and Prevention estimates more than 15% of adults in the United States, over 30 million Americans have chronic kidney disease (CKD). Podocytes are ep...
Pathologic Signaling Pathways in AML Cells
Abstract: Acute myeloid leukemia (AML) is a serious blood cancer that affects United States Veterans and other individuals. Multiple studies have demonstrated that active signaling...
Pharmacological Npt2a inhibition as a treatment for hyperphosphatemia in chronic kidney disease
The precise regulation of the body's phosphate homeostasis is a critical task. Treatment of hyperphosphatemia, which becomes inevitable in later stages of chronic kidney disea...
Transcriptional Control of Skeletal Muscle Atrophy
Skeletal muscle atrophy results from insufficient nutrition, aging, certain medications, and a wide range of medical illnesses including cancer, diabetes mellitus, heart or renal f...
Traumatic Brain Injury and Vascular Disease
Objective: Traumatic brain injury (TBI) is a common cause of morbidity and mortality in the veteran population. In the United States, there are an estimated 5.3 million people livi...
Host factors affecting susceptibility to Candida auris.
This VA Merit research project aims to define host factors associated with mucosal infection by an emerging multi-drug resistant human fungal pathogen, Candida auris. Most human fu...
A role and regulation of glucose responsive lipolysis in pancreatic beta cells
T2D is a major health problem for US veterans that imposes significant physical, financial, and emotional tolls. Thus, there is a strong and urgent need for an effective and widely...
