Education and Training

David Loane, PhD, is an Associate Professor and Faculty Member at the Shock, Trauma and Anesthesiology Research (STAR) Center at the University of Maryland School of Medicine, Baltimore, Maryland. Dr. Loane conducted his graduate studies at the Department of Pharmacology and MRC Center for Synaptic Plasticity, University of Bristol, England, and obtained his PhD in Neuroscience in 2005. He then pursued postdoctoral training with Dr. Marina Lynch at Trinity College Institute of Neuroscience, Trinity College Dublin, Ireland, where he studied neuroinflammatory changes in the aged and Alzheimer's disease (AD) brain. In 2007 Dr. Loane was recruited to the Department of Neuroscience, Georgetown University Medical Center, Washington D.C., to perform further postdoctoral training on experimental models of traumatic brain injury (TBI) under the mentorship of Dr. Alan Faden. He joined the faculty of the University of Maryland School of Medicine in November 2009 and is currently Associate Professor of Anesthesiology.


Dr. Loane leads a multi-disciplinary research team dedicated to studying the complexities of TBI, neuroinflammation and tissue repair. Specifically, his research program investigates the activation status and functional role of resident microglia and infiltrating blood-borne monocytes in the TBI brain, and to determine how they contribute to chronic neurodegeneration and long-term neurological dysfunction after brain trauma.

His group is seeking to elucidate the mechanisms that regulate microglial/macrophage activation with the goal of manipulating these cells to attenuate destructive pro-inflammatory responses, and promote neuroprotective anti-inflammatory and reparative responses. Ongoing studies include examining: 1) the function and phenotypes of microglia/macrophages following acute TBI, and how they contribute to chronic pathologies; 2) the signaling pathways that drive anti-inflammatory activation of microglia/macrophages, and whether these pathways can be manipulated after TBI; 3) how age affects microglia/macrophage polarization and the neuroinflammatory response after TBI.

The mission of his group is to elucidate the pathophysiological mechanisms underlying post-traumatic neuroinflammation, neurodegeneration and loss of neurological function, and to develop novel treatment strategies that will translate to the clinic for human head injury.

Lab Techniques and Equipment

A diverse array of in vitro and in vivo experimental models are used to study pathophysiological mechanisms of TBI and neurodegeneration. These include: experimental TBI models (controlled cortical impact, fluid percussion injury, diffuse brain injury; mice and rats), transgenic mouse models, mechanical injury in primary cortical neurons/neuron-glia co-cultures, cell cultures (primary microglia, neurons, astrocytes; cell lines), immunohistochemistry and state-of-the-art microscopy (light/fluorescence/confocal) and image analysis (stereology), behavioral analysis (cognitive, motor, depression/anxiety function), flow cytometry and FACS analysis, molecular biology (qPCR, Western), magnetic resonance imaging (T2-weighted, DTI).
