The University of North Carolina at Chapel Hill (UNC), founded in 1789, stands as the oldest public university in the United States and a leading center for neurodegeneration research in the American Southeast. As the flagship institution of the UNC System, the university has established comprehensive research programs addressing Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and related neurodegenerative conditions through the Bryan Alzheimer's Disease Research Center, the UNC Neuroscience Center, and the Carolina Alzheimer's Network. The institution's research portfolio spans from fundamental studies of protein aggregation and neuroinflammation to clinical biomarker validation, therapeutic trials, and health disparities research. Located in Chapel Hill, North Carolina, UNC benefits from strong regional collaborations with Duke University, Wake Forest University, and other research institutions in the Research Triangle, creating a vibrant ecosystem for neuroscience research that attracts top talent and generates significant contributions to understanding neurodegenerative disease mechanisms.
The university's approach to neurodegeneration research emphasizes translational science that bridges the gap between laboratory discoveries and clinical application. This strategic focus has enabled UNC to make meaningful contributions to biomarker development, therapeutic intervention trials, and understanding of disease mechanisms. The integration of basic science research with clinical expertise creates an environment where discoveries can be rapidly translated into improved patient care, positioning UNC as a national leader in the effort to develop effective treatments for neurodegenerative diseases.
The University of North Carolina at Chapel Hill traces its origins to the colonial period, making it the oldest public university in the United States. The university's medical school, established in the nineteenth century, has evolved into a comprehensive academic medical center that integrates research, education, and patient care. The development of neuroscience research at UNC accelerated significantly in the latter decades of the twentieth century, driven by institutional investment in research infrastructure and recruitment of leading neuroscientists.
The establishment of the UNC Neuroscience Center in the 1980s marked a pivotal moment in the university's neuroscience research trajectory. This multidisciplinary research institute brought together faculty from multiple departments to address fundamental questions in neuroscience, creating the foundation for later expansion into neurodegeneration research. The subsequent establishment of the Bryan Alzheimer's Disease Research Center (ADRC) in 1991, funded by the National Institute on Aging, created a dedicated center for Alzheimer's disease research that would become a major contributor to the national Alzheimer's disease research infrastructure.
The Carolina Alzheimer's Network, established in the early 2000s, further consolidated neurodegeneration research at UNC by creating a framework for interdisciplinary collaboration across basic science, clinical research, and population science. This network brought together investigators from diverse backgrounds to address the full spectrum of challenges in Alzheimer's disease and related disorders, from basic mechanisms to clinical translation and public health interventions.
The Bryan Alzheimer's Disease Research Center represents UNC's flagship program in neurodegeneration research, funded by the National Institute on Aging since 1991. The Bryan ADRC maintains a comprehensive research program that addresses the full spectrum of Alzheimer's disease, from preclinical stages through advanced dementia, with particular emphasis on early detection, biomarker development, and therapeutic intervention.
The Bryan ADRC research program encompasses multiple interconnected focus areas that address critical questions in Alzheimer's disease pathogenesis and treatment. Early detection research investigates the biological changes that occur before clinical symptoms become apparent, including amyloid and tau accumulation, neurodegeneration, and network dysfunction. Studies employ advanced neuroimaging techniques, cerebrospinal fluid and blood biomarkers, and neuropsychological assessments to characterize the preclinical and prodromal stages of disease.
Biomarker development represents a central focus of the Bryan ADRC research program, with investigators working to identify and validate markers that can predict disease onset, track progression, and monitor treatment response [@morris2022]. The center has contributed significantly to understanding the relationship between amyloid and tau pathology and clinical symptoms, informing the development of biomarker-based diagnostic criteria that now guide clinical practice.
Clinical trials for Alzheimer's therapeutics represent an essential component of the Bryan ADRC program, with investigators leading and participating in studies of disease-modifying therapies targeting various aspects of disease pathogenesis. These trials evaluate antibodies targeting amyloid-beta, tau, and other disease mechanisms, contributing to the global effort to develop effective treatments that can slow or halt disease progression [@friedland2022].
A distinctive feature of the Bryan ADRC program is its emphasis on understanding and addressing health disparities in Alzheimer's disease. North Carolina has a diverse population that includes significant numbers of African American and rural communities that are disproportionately affected by Alzheimer's disease but underrepresented in research. The center's health disparities research addresses this gap through community engagement, recruitment of diverse participant cohorts, and investigation of social and biological factors that contribute to differential disease risk and outcomes [@martinez2024].
The UNC Neuroscience Center serves as the primary hub for basic neuroscience research at the university, housing faculty whose work spans cellular and molecular neuroscience, systems neuroscience, and translational research on neurological disorders. With over 150 faculty members, the center represents one of the largest neuroscience research institutes in the southeastern United States, contributing significantly to understanding the mechanisms underlying neurodegenerative diseases.
Neuroscience Center investigators conduct extensive research on Alzheimer's disease pathogenesis, addressing questions ranging from molecular mechanisms of protein aggregation to circuit-level dysfunction underlying cognitive decline. Studies on amyloid-beta and tau pathology examine how these hallmark proteins accumulate in the brain and exert toxic effects on neurons and synapses. The work on tau propagation has been particularly influential, demonstrating how pathological tau spreads through neural circuits to spread neurodegeneration [@zhou2023].
Research on neuroinflammation investigates how microglia and other immune cells contribute to disease pathogenesis, with studies revealing both protective and harmful roles for neuroimmune responses [@chen2024]. Understanding the complex interactions between protein pathology and neuroinflammation is essential for developing therapeutic interventions that modulate immune responses appropriately.
Studies on synaptic dysfunction address one of the earliest and most important pathological features of Alzheimer's disease, examining how amyloid and tau disrupt synaptic communication and ultimately lead to cognitive decline. This work identifies molecular targets for therapeutic intervention and reveals how different aspects of pathology contribute to specific cognitive deficits [@gillespie2023].
The Neuroscience Center maintains robust research programs on Parkinson's disease and related movement disorders, addressing both motor and non-motor aspects of these conditions. Research on alpha-synuclein aggregation examines the molecular mechanisms underlying this key pathological feature of Parkinson's disease, including the factors that trigger aggregate formation and the mechanisms by which aggregates spread through the brain [@reardon2022].
Studies on LRRK2, one of the most common genetic risk factors for Parkinson's disease, examine how mutations in this gene contribute to disease pathogenesis [@williams2024]. The work on LRRK2 kinase activity has identified this enzyme as a promising therapeutic target, with several LRRK2 inhibitors advancing through clinical development.
Deep brain stimulation research examines how this treatment affects brain networks and develops improved stimulation protocols that may provide better symptom control with fewer side effects [@steck2024]. The clinical program at UNC is recognized internationally for its expertise in movement disorders treatment and research.
Research on ALS and frontotemporal dementia (FTD) addresses the shared pathological features of these conditions, particularly the role of TDP-43 proteinopathy [@trojanowski2023]. Studies examine how TDP-43 aggregation disrupts RNA metabolism and other cellular functions essential for neuronal survival, revealing potential therapeutic targets.
The research on C9orf72 hexanucleotide repeat expansions, the most common genetic cause of familial ALS and FTD, has been particularly productive [@goldman2023]. Studies on how these repeats cause toxicity have revealed novel disease mechanisms and identified potential therapeutic approaches.
The Carolina Alzheimer's Network provides a framework for interdisciplinary collaboration that brings together basic scientists, clinical researchers, epidemiologists, and social scientists to address Alzheimer's disease from multiple perspectives. This network leverages the diverse expertise across UNC to attack the disease from multiple angles, creating synergies that would not be possible through isolated research programs.
The network integrates basic science research across multiple departments and centers, facilitating collaboration between investigators who study protein aggregation, neuroinflammation, synaptic dysfunction, and other disease mechanisms. This integration enables systems-level understanding of disease pathogenesis that can inform therapeutic development.
Clinical research coordinated through the Carolina Alzheimer's Network encompasses diagnostic studies, therapeutic trials, and investigations of non-pharmacological interventions. The network provides infrastructure for rapid translation of basic findings into clinical studies, accelerating the development of new treatments.
Epidemiological research within the network investigates risk factors for Alzheimer's disease and related disorders, including genetic, environmental, and lifestyle factors. Population studies examine how these factors interact to influence disease risk and how interventions might modify risk. The public health research program addresses how to translate research findings into community-level interventions that can reduce disease burden.
