The Parkinson’s Research Podcast: New Discoveries in Neuroscience – Details, episodes & analysis

Sleep disturbances, such as insomnia, sleep fragmentation, excessive daytime sleepiness, and REM sleep behavior disorder are common in people with Parkinson's disease (PD). Poor sleep quality can also impact other domains of function, including motor function. Prior research has shown that a type of photoreceptor cell in the retina, called melanopsin cells, provide the main light signals to the brain to initiate sleep, and function of these cells is impaired in PD. Dr. Beatix Feigl and her colleagues developed a novel light therapy intervention that selectively activates the melanopsin photoreceptor cells, and in this episode, she discusses the results of a recent randomized controlled trial evaluating the efficacy of this melanopsin photoreceptor-directed light therapy on sleep and circadian rhythm, as well as motor behaviors. She also discusses her earlier work on melanopsin cells that led to the development of standard measures to assess their function. Beatrix is an Ophthalmologist and an Associate Professor in the School of Biomedical Sciences and Center for Vision and Eye Research, as well as the Faculty of Health, at the Queensland University of Technology.

Though existing evidence supports that dysfunction in the clearing of cellular debris plays an important role in the development of Parkinson's disease, many unanswered questions remain regarding the mechanisms of the autophagy-lysosomal pathway involved in this process. In particular, research in the field has been limited by a lack of reliable, quantitative tests for monitoring autophagy-lysosome activity. In this interview, Dr. Zhenyu Yue describes his research investigating the cellular and molecular mechanisms for Parkinson's disease and other neurodegenerative diseases, focusing on their work examining the regulation of the autophagy-lysosomal pathway, potential therapeutic targets, and MJFF-funded research that aims to develop sensitive, robust autophagy-lysosome assays to facilitate the discovery of biomarkers for PD using stem cell-derived neurons and biofluids. Zhenyu is the Aidekman Research Professor in the Department of Neurology and Friedman Brain Institute at the Icahn School of Medicine at Mount Sinai. He is also the Director of the Center of Parkinson’s Disease Neurobiology and Director of Basic Research of Movement Disorders at Mount Sinai.

Atypical Parkinsonian Syndromes, such as progressive supranuclear palsy (PSP), multiple system atrophy (MSA), corticobasal degeneration (CBD), and dementia with Lewy bodies are often initially diagnosed as Parkinson's disease. Incorrect, incomplete, or delayed diagnoses are barriers to beginning the most appropriate treatment early in the disease course. More research is needed to facilitate early diagnoses, understanding of disease pathogenesis, and monitoring of disease progression. However, largescale, collaborative initiatives are making meaningful progress in understanding genetic contributors to disease pathology and progression in Parkinson's disease. Our guest in this episode, Dr. Huw Morris, has spent more than twenty five years researching Parkinson's disease and parkinsonian syndromes, and he shares highlights from recent work, including studies on the genetics and pathogenesis of Parkinson’s disease and other parkinsonian syndromes. Huw is Professor of Clinical Neuroscience at University College London Institute of Neurology, as well as an Honorary Consultant Neurologist at the Royal Free Hospital and the National Hospital for Neurology and Neurosurgery Queen Square.

For many years, Parkinson's disease and dementia with Lewy bodies have been defined using clinical features. With recent advances in biomarkers, particularly the alpha-synuclein seed amplification assay that allows us to detect misfolded and aggregated alpha-synuclein in cerebrospinal fluid, it is now possible to identify the presence of pathological neuronal alpha-synuclein in living patients. With input from diverse stakeholders, a new biological definition of neuronal alpha-synuclein disease (NSD) has been proposed, along with an integrated staging system (NSD-ISS). In this interview, we discuss the development of this biologic definition for Parkinson’s disease and the staging system with Dr. Lana Chanine, one of the lead authors of the recently published manuscript in The Lancet Neurology that describes this work. It is important to note that the NSD and NSD-ISS are for research purposes only right now, and they are not ready to be implemented in the clinic. Lana is a Movement Disorders Neurologist and Associate Professor of Neurology at the University of Pittsburgh.

In neurodegenerative conditions such as Parkinson's disease (PD), patients often do not receive a diagnosis until the hallmark motor symptoms begin to manifest. This can be a decade or more after substantial changes start occurring in the brain. A major goal of the PD research field has been to develop methods for earlier detection and intervention. Over the years, there have been substantial advances in neuroimaging techniques and biological biomarkers that have allowed us to more accurately identify patients with Parkinson's disease, including the recent development of the alpha-synuclein seed amplification assay. In this episode, Dr. John Seibyl discusses his early work on neuroimaging in Parkinson's disease through to the groundbreaking, large-scale clinical trials he is involved with for assessing the impacts of neuroprotective drugs for Parkinson's disease as well as Alzheimer's disease. He also shares his perspectives as a researcher and a patient with Parkinson's disease. John is Chairman of the Board, Co-Founder, and Senior Scientist of the Institute for Neurodegenerative Disorders in New Haven, Connecticut. He is also a board-certified physician in both Psychiatry and Nuclear Medicine, and he is an Adjunct faculty member in Neurology at Yale University School of Medicine.

A growing body of evidence is expanding our understanding of the links between inflammation, our immune responses, brain health, and neurodegeneration. In particular, several genes associated with Parkinson's (including LRRK2) are known to be involved in inflammation, and peripheral inflammation has been shown to influence brain function and contribute to the development of neurodegenerative diseases. Better understanding the roles of inflammation and our immune responses in Parkinson's disease is important for developing new treatments and strategies to slow or prevent disease progression. In this episode, Dr. Malú Gámez Tansey talks about her research at the intersection of immunology, neuroscience, and genetics. She describes new findings and current projects in her lab, discusses advances in neuroimmunology, and shares her insights on important areas of opportunity in the field. Malú is the Norman and Susan Fixel Chair in Parkinson's Disease, Professor of Neuroscience and Neurology, and Director of the Parkinson's Foundation Research Center of Excellence at the University of Florida College of Medicine. She's also editor-in-chief of Nature Partner Journal Parkinson's Disease.
