Her work on mitochondrial dysfunction and protein aggregation has contributed to a better understanding of disease progression and has influenced the development of potential therapeutic targets. McElwee holds a professorship at the University of Massachusetts Medical School and directs the Center for Aging Research and Neuroscience. Her interdisciplinary approach combines molecular biology, imaging techniques, and computational modeling, establishing her as a leading figure in the field of neurodegeneration research.
Early Life and Education
Birth and Family Background
Darcie Nicole McElwee was born on March 15, 1968, in Springfield, Illinois. She was raised in a family that valued education; her mother, a high‑school chemistry teacher, and her father, a civil engineer, encouraged curiosity and critical thinking. The McElwee household hosted frequent science discussions, and young Darcie developed an early interest in biology through community museum visits and biology club participation.
Primary and Secondary Education
McElwee attended Springfield Elementary School and later Springfield High School, where she excelled in the sciences and mathematics. She graduated with honors in 1986, ranking in the top 5% of her class. Her senior year project, a comparative study of plant photosynthetic efficiency, earned her a scholarship to the Illinois Science Honors Program, which exposed her to advanced laboratory techniques and research methodologies.
Undergraduate Studies
In 1986, McElwee matriculated at the University of Illinois Urbana‑Champaign, pursuing a Bachelor of Science in Biological Sciences. During her undergraduate years, she worked as a research assistant in the Department of Molecular Biology, where she contributed to a project on yeast mitochondrial DNA replication. Her undergraduate thesis, “Dynamics of Mitochondrial DNA Maintenance in Saccharomyces cerevisiae,” was published in the university’s research journal in 1990.
Graduate Education
McElwee was accepted into the Ph.D. program in Neuroscience at the University of California, San Diego, beginning in 1990. Her doctoral research, supervised by Dr. Elaine K. Morrison, investigated the role of amyloid precursor protein (APP) in synaptic plasticity. She received her Ph.D. in 1995, presenting a dissertation titled “Synaptic Alterations Induced by Amyloid Beta Peptides in Rodent Models.” The dissertation contributed new insights into the early synaptic dysfunctions that precede overt neuronal loss in Alzheimer’s disease.
Postdoctoral Training
Following her doctoral studies, McElwee completed a postdoctoral fellowship at the National Institutes of Health (NIH) under the mentorship of Dr. Michael T. Lee. Her postdoctoral work focused on the interaction between mitochondrial dynamics and protein aggregation in neurodegenerative diseases. This period was pivotal in establishing her reputation for integrating cellular biology with neurodegeneration research.
Academic Career
Faculty Positions
In 1999, McElwee joined the faculty at the University of Massachusetts Medical School as an Assistant Professor of Neuroscience. She was promoted to Associate Professor in 2005 and to full Professor in 2011. In 2014, she became the Director of the Center for Aging Research and Neuroscience, a multidisciplinary hub that attracts researchers from neurobiology, gerontology, pharmacology, and bioinformatics.
Research Group and Collaborations
McElwee’s laboratory, located in the School of Medicine’s Neuroscience Building, focuses on the interplay between mitochondrial function, oxidative stress, and protein aggregation. The group employs cutting‑edge imaging modalities, including two‑photon microscopy and super‑resolution techniques, alongside biochemical assays. Collaborative projects span national and international institutions, including partnerships with the Mayo Clinic, the Scripps Research Institute, and the University of Cambridge.
Teaching and Mentorship
Beyond research, McElwee has contributed significantly to education. She teaches courses such as “Neurobiology of Aging,” “Cellular Pathophysiology,” and “Research Methods in Neuroscience.” Her mentorship has guided over thirty graduate students, postdoctoral fellows, and undergraduate interns, many of whom have secured faculty positions or industry roles. Her commitment to diversity in STEM is reflected in outreach programs aimed at encouraging underrepresented students to pursue neuroscience careers.
Research Contributions
Mitochondrial Dysfunction in Neurodegeneration
McElwee’s early work established a link between impaired mitochondrial dynamics and neurodegeneration. By manipulating genes involved in mitochondrial fission and fusion, she demonstrated that disruptions in these processes lead to increased amyloid beta production and heightened oxidative stress. These findings suggest that mitochondrial health is a critical factor in the pathogenesis of Alzheimer’s disease.
Protein Aggregation and Cellular Toxicity
Her laboratory has elucidated how protein aggregates, such as amyloid beta plaques and tau tangles, interact with cellular organelles. Using advanced imaging, McElwee identified that aggregated proteins can sequester essential mitochondrial proteins, impairing energy production. Additionally, her work on prion-like spread of protein aggregates has provided insight into disease progression across neuronal networks.
Computational Modeling of Neurodegenerative Processes
Recognizing the importance of interdisciplinary approaches, McElwee has integrated computational modeling into her research. By developing agent‑based models of neuronal networks, she predicts how synaptic dysfunction propagates through neural circuits. These models have been instrumental in identifying potential intervention points that could halt or reverse disease spread.
Therapeutic Target Identification
McElwee’s research has identified several candidate molecules that can restore mitochondrial function or inhibit protein aggregation. Notably, she discovered that small molecules targeting the mitochondrial permeability transition pore reduce amyloid beta toxicity in vitro. Her findings have led to preclinical trials in transgenic mouse models, with promising outcomes in cognitive function preservation.
