抖M女仆 Researchers Receive Grants to Combat Alzheimer鈥檚 Disease
About 580,000 people aged 65 and older are living with Alzheimer鈥檚 disease in Florida and that number is expected to soar to 720,000 by 2025.
Four researchers from 抖M女仆 鈥檚 and have received grants totaling $641,818 from the 鈥檚 . Award recipients also represent the 抖M女仆 Brain Institute, which advances neuroscience research, promotes neuroscience education, facilitates translational research discoveries and enhances public awareness, and the 抖M女仆 Institute for Human Health and Disease Intervention (I-HEALTH), created to advance health through pioneering research and practical applications.
鈥淲e are excited to receive these important grants from the Ed and Ethel Moore Alzheimer鈥檚 Disease Research Program,鈥 said , Ph.D., senior associate dean for research and chair of the in the Schmidt College of Medicine. 鈥淯sing collaborative and multi-disciplinary approaches, our researchers are striving to understand basic biological mechanisms and cultivate new strategies to combat Alzheimer鈥檚 disease in South Florida and beyond through patient-centered research and discovery.鈥
The Ed and Ethel Moore Alzheimer鈥檚 Disease Research Program was established to fund research aimed at preventing or finding a cure for Alzheimer鈥檚 disease (AD). Objectives include improving the health of Floridians by researching better prevention, diagnoses, treatments and cures for AD, expanding the foundation of knowledge relating to prevention, diagnosis, treatment and cures, and stimulating economic activity in Florida in areas related to AD research.
鈥淎bout 580,000 people aged 65 and older are living with Alzheimer鈥檚 disease in Florida and that number is expected to soar to 720,000 by 2025. Alzheimer鈥檚 disease is the sixth leading cause of death in Florida and more than 527,000 family caregivers bear the burden of the disease in our state,鈥 said Randy Blakely, Ph.D., executive director, 抖M女仆 Brain Institute. 鈥淭hese grants from the Ed and Ethel Moore Alzheimer鈥檚 Disease Research Program will help to propel our researchers鈥 pioneering work.鈥
More than 5 million Americans are living with AD and as many as 16 million will have the disease in 2050. The cost of caring for those with AD and other dementias totaled about $277 billion in 2018, increasing to $1.1 trillion (in today鈥檚 dollars) by mid-century. Nearly one in every three seniors who dies each year has AD or another dementia.
鈥淥ur researchers have received these grants from the Ed and Ethel Moore Alzheimer鈥檚 Disease Research Program to advance scientific research and clinical care for one of the most complex diseases that impacts our aging patient population in Florida and elsewhere,鈥 said Gregg Fields, Ph.D., executive director, 抖M女仆聽 聽 聽 I-HEALTH. 鈥淎s Alzheimer鈥檚 disease and other related dementias continue to rapidly rise, research is imperative to help us understand what causes the disease, help us develop effective treatments, improve patient care, and ultimately one day find a cure.鈥 聽
The 抖M女仆 projects supported by the Ed and Ethel Moore Alzheimer鈥檚 Disease Research Program are:
- 鈥淎 Novel Therapeutic Strategy for Alzheimer鈥檚 Disease鈥 (Qi Zhang, Ph.D., research assistant professor of , 抖M女仆鈥檚 , and a member of the 抖M女仆 Brain Institute): To date, clinical trials for drugs for AD based on the amyloid hypothesis have been lackluster, leading to a renewed search for alternative theories and different pathogenic factors. Extensive genome-wide association studies of sporadic AD have consistently identified genetic risk factors associated with cholesterol (Chol) metabolism and cell membrane trafficking. More and more evidence has shown that neuronal Chol deficiency, rather than surfeit, is a causative factor for aging-associated brain disorders, including AD. For this project, Zhang will focus on rebalancing brain cholesterol, especially at nerve terminals, to reduce and even reverse neurodegeneration. By combining the power of induced human pluripotent stem cells (hiPSC) and novel mouse models, this preclinical project will provide new pathological insights as well as novel therapeutic strategies for AD.聽
- 鈥淩ole of Hypoxia in Triggering Alzheimer鈥檚 Disease Pathogenesis: Sulindac as a Potential Therapeutic Intervention鈥 (, Ph.D., a professor of biomedical science, 抖M女仆鈥檚 Schmidt College of Medicine, and a member of the 抖M女仆 Brain Institute and 抖M女仆 I-HEALTH): Oxidative damage and mitochondrial dysfunction are key factors in neuronal hypoxic injury and in development of AD; however, there is no effective therapy that targets these mechanisms. Prentice previously demonstrated that the non-steroidal anti-inflammatory drug (NSAID) sulindac protects the myocardium against hypoxia/ischemia through the mechanisms of ischemic preconditioning, independent of its NSAID activity. For this project, Prentice and his team are investigating whether sulindac will protect against A-Beta aggregation and dysfunctional tau phosphorylation using an in vitro cell culture and an in vivo transgenic mouse model of AD. If successful, these studies will be the first to show the therapeutic potential of sulindac in slowing down the progression of AD.
- 鈥淭he Cellular Basis for Neurodegeneration in a Drosophila Model of Alzheimer鈥檚鈥 (, Ph.D., a professor of biological sciences, 抖M女仆鈥檚 , and a member of 抖M女仆 I-HEALTH): Powerful genetics in the fruit fly, Drosophila melanogaster, allow for manipulating gene function in defined neural circuits. This project will directly address the mechanisms of neurodegeneration and will use genomic approaches and behavioral screening to identify novel genetic regulators of neurodegeneration in AD models. Given the genetic conservation associated with aging and plasticity between fruit flies and mammalian systems, these findings have potential to identify conserved regulators of AD-mediated neurodegeneration that can be further investigated in mammalian models.聽
- 鈥淧ostdoctoral Research Fellowship in Neuropsychology and Brain Biomarkers of Abnormal Aging鈥 (Idaly Velez-Uribe, Ph.D., 抖M女仆鈥檚 Charles E. Schmidt College of Science, and , Ph.D., a professor and associate chair of psychology, 抖M女仆鈥檚 Charles E. Schmidt College of Science, and a member of the 抖M女仆 Brain Institute and 抖M女仆 I-HEALTH): There is a scarcity of trained researchers in clinical neuropsychology who can evaluate and diagnose Hispanics in a culturally sensitive manner, including cognitively normal individuals and those presenting early signs of neurodegenerative diseases. Furthermore, standard clinical research trainings do not emphasize the role of cultural factors, quality and level of education, and language experience (i.e., bilingualism) in assessments and interventions of the progression of abnormal aging. Moreover, ethnic minorities are underrepresented as professionals within the field of neuropsychology and as faculty in doctoral programs in psychology. This 抖M女仆 project has been designed to target this disparity. Velez-Uribe鈥檚 investigative work will focus on the complex interplay between bilingualism, cultural factors, cognitive decline, and biological markers of dementia.
