With an annual research portfolio exceeding $150 million, the institution maintains a comprehensive focus on [Alzheimer's disease](/diseases/alzheimers-disease), [Parkinson's disease](/diseases/parkinsons-disease), [amyotrophic lateral sclerosis (ALS)](/diseases/amyotrophic-lateral-sclerosis), and [frontotemporal dementia](/diseases/frontotemporal-dementia). The university's unique position combining basic science research with clinical translation has led to significant contributions in biomarker discovery, therapeutic development, and patient care models^[3]^.
The institution's research enterprise spans multiple dedicated centers focusing on different aspects of neurodegeneration. The [Jefferson Center for Neurodegenerative Diseases](/institutions/jefferson-center-for-neurodegenerative-diseases) serves as the umbrella organization coordinating these efforts, while specialized institutes like the Marcus Institute for Alzheimer's Disease and the Parkinson's Disease Research Center provide disease-specific focus^[4]^. This organizational structure enables both deep expertise in individual disease areas and cross-disciplinary collaboration essential for tackling the complex pathophysiology of neurodegenerative disorders.
Thomas Jefferson University's origins trace to 1824 when Jefferson Medical College was founded, making it the ninth oldest medical school in the United States. The institution's commitment to medical innovation was evident from its earliest days, and over the subsequent two centuries, it evolved from a single medical college into a comprehensive academic health system. The 2017 merger with Philadelphia University added significant breadth to the university's academic portfolio while maintaining its historic strength in health sciences^[1]^.
The evolution of Jefferson's neuroscience research programs accelerated dramatically in the early 2000s with the establishment of dedicated neurodegenerative disease research centers. The Farber Institute for Neurosciences, founded in 2005, created a foundational center for basic neuroscience research that subsequently seeded the more disease-specific institutes that exist today. This strategic growth reflected both the increasing public health burden of neurodegenerative diseases and Jefferson's recognition of the opportunity to make transformative contributions to the field^[5]^.

The institute houses laboratories focused on cellular and molecular neuroscience, systems neuroscience, developmental neuroscience, and computational neuroscience. This breadth enables investigators to pursue questions at multiple levels of biological organization^[5]^.
Research conducted at the Farber Institute has made significant contributions to understanding the fundamental mechanisms underlying neurodegeneration. Studies on neurotrophic factor signaling, conducted under Dr. Stephen D. Skaper's leadership, have elucidated how brain-derived neurotrophic factor (BDNF) and related molecules support neuronal survival and synaptic plasticity. These findings have implications for developing neuroprotective therapies applicable to multiple neurodegenerative conditions^[10][11]^.
The institute also maintains robust programs in neuroimmunology, investigating the role of neuroinflammation in neurodegenerative disease pathogenesis. This work has revealed that microglial activation and inflammatory cytokine release contribute significantly to neuronal dysfunction and death, suggesting that immunomodulatory approaches may have therapeutic value in conditions like Alzheimer's and Parkinson's disease^[12]^.
The Parkinson's Disease Research Center at Jefferson focuses on understanding Parkinson's disease pathophysiology and developing novel therapeutic approaches. The center's research encompasses both sporadic and genetic forms of Parkinson's disease, recognizing that insights from genetic forms often inform understanding of the more common sporadic disease^[13]^.
Dr. Richard J. Smeyne's research program at the center has made important contributions to understanding how environmental toxins, including MPTP and related compounds, induce Parkinsonism. These studies have revealed that mitochondrial dysfunction plays a central role in toxin-induced dopaminergic neurodegeneration, and similar mechanisms appear to operate in sporadic Parkinson's disease^[13][14][15]^. Current research extends these findings to investigate how alpha-synuclein aggregation interacts with mitochondrial dysfunction to produce the characteristic pathology of Parkinson's disease^[15]^.
The center's clinical research program includes investigations of deep brain stimulation (DBS) for Parkinson's disease treatment. Collaborations with the functional neurosurgery team have evaluated the relative benefits of subthalamic nucleus (STN) versus globus pallidus interna (GPi) stimulation, providing evidence to guide surgical target selection^[16][17]^. Additionally, the center participates in clinical trials of disease-modifying therapies targeting alpha-synuclein pathology and neuroprotection^[17]^.

Samples include cerebrospinal fluid (CSF), plasma, serum, DNA, RNA, and post-mortem brain tissue. The repository operates under strict ethical guidelines and maintains comprehensive annotation linking samples to clinical data^[6]^.
The biorepository has been instrumental in biomarker discovery efforts at Jefferson. Studies using CSF samples have identified novel biomarker candidates for Alzheimer's disease diagnosis and progression monitoring. The repository also supports genetic studies, with DNA samples used for genome-wide association studies (GWAS) and whole-exome sequencing investigations^[21][22]^.
The Cellular Models Core provides infrastructure for generating and characterizing cellular models of neurodegenerative diseases. The core supports generation of induced pluripotent stem cells (iPSC) from patient samples and their differentiation into neurons, astrocytes, and microglia. These patient-derived models enable investigation of disease mechanisms in human cells^[23]^.
Dr. D. Sareen's laboratory has developed iPSC-derived neuronal models of Alzheimer's disease that exhibit characteristic pathological features including amyloid-beta production and tau hyperphosphorylation. These models have been used for drug screening experiments identifying compounds that modify disease-relevant phenotypes. The cellular models approach offers advantages over traditional animal models by capturing human-specific disease biology^[23][24]^.
