Instructor, Dominick P. Purpura Department of Neuroscience
Research Interest: I have been working in the field of Neuroscience since 2005, and my research focuses on the investigation of glia-neuron interactions in regard to protection of neuronal function and survival in various neuronal disorders, including neuropathic and inflammatory pain, epilepsy and Alzheimer’s. My current research focuses on the role of satellite glia cells in driving and controlling aberrant neuronal activity in inflammatory- and neuropathic induced pain, and the identification of new targets for successful pain therapies. The awareness of the important role of glia for normal neuronal function has increased in the neuroscience field in recent years, but their mode of action in modulating neuronal activity by gliotransmitter and cytokine release is not completely understood. I have not only a great interest in dissecting these important mechanisms in in vitro cell biological and protein biochemistry experiments, but am also fascinated by analyzing my hypotheses in animal models of human diseases using in vivo behavioral experiments as they represent the complexity of life.
Collaborations: Dept of Orthopedics (arthritis, low back pain), Dept of Urology (pelvic pain) and rodent behavior (Behavior core) to extend translational pain research at Einstein.
Techniques: development of translational disease models; rodent behavioral tests; imaging; confocal microscopy; biostatistics; live cell/tissue assays (ATP assay, Dye uptake); molecular biology (PCR arrays, qPCR), protein biochemistry (ELISAs and immunostaining), and calcium imaging experiments
