David Stellwagen, Ph.D. is a Senior Scientist at the Research Institute of the McGill University Health Centre (RI-MUHC) at the Montreal General Hospital site, and a Professor in the Department of Neurology and Neurosurgery within the Faculty of Medicine and Health Sciences at McGill University. He is affiliated with the Program in Brain Repair and Integrative Neuroscience and the Center for Translational Biology, focusing his research on neuroimmune interactions and synaptic function regulation.
Dr. Stellwagen's research primarily investigates how inflammatory signals, particularly tumor necrosis factor (TNF), regulate neuronal function and synaptic connections. His groundbreaking work has demonstrated that inflammatory signals are crucial for maintaining normal neuronal activity homeostasis through the regulation of synaptic strength. His laboratory explores how these mechanisms contribute to brain function changes observed in neurological and psychiatric disorders including addiction, autism, ALS, and Huntington's Disease, where neuroinflammation is commonly present.
Analysis of Dr. Stellwagen's recent publications reveals a consistent focus on TNF-mediated synaptic plasticity mechanisms across multiple neurological contexts. His work spans from fundamental molecular mechanisms of homeostatic synaptic scaling to applications in neurodegenerative diseases and psychiatric conditions. A significant portion of his research examines the role of glial cells (particularly astrocytes and microglia) as sources of TNF that regulate synaptic function, and how these pathways are involved in stress responses, anxiety behaviors, and disease pathology.
Dr. Stellwagen's research program has established important connections between neuroimmune signaling and neural circuit function, with particular emphasis on how inflammatory molecules like TNF serve essential physiological functions in maintaining neural homeostasis while also contributing to pathological states when dysregulated. His work bridges basic neurobiology with clinical relevance across multiple neurological conditions characterized by neuroinflammation.
