Elias Aizenman was born and raised in Mexico City. He attended Boston University as an undergraduate, where he received training in neurobiology in the laboratory of Christopher Price, working on the retrograde axonal transport of free glycine in identified neurons of Aplysia. He also performed microbiological field work for Lynn Margulis in Laguna Figueroa, Baja California, Mexico. His graduate work was in toxicology at the Johns Hopkins University, where he studied the mechanism of anticholinesterase-induced generation of antidromic action potentials at the mouse neuromuscular junction with George Bierkamper and Elise Stanley. During his postdoctoral work with Stuart Lipton at Boston Children’s Hospital and Harvard Medical School, he discovered the redox modulatory site of the NMDA receptor in collaboration with Ralph Loring. With Paul Rosenberg, he demonstrated the oxidative conversion of L-DOPA to an excitotoxin. He began his independent career in the Department of Neurobiology at the University of Pittsburgh School of Medicine in 1989. In Pittsburgh, together with Ian Reynolds, Elias described the oxidative liberation of intracellular zinc as a critical component of neurotoxic cell signaling pathways. With Ed Levitan, he identified Kv2.1 as the channel responsible for the requisite loss of intracellular potassium during neuronal apoptosis.
Research in Elias’s laboratory is directed towards investigating cellular signaling processes leading to neuronal cell death. Cellular pathways leading to cell death are molecularly dissected in order to provide novel therapeutic targets to treat neurodegenerative disorders. This laboratory works on potential common final mediators of cell death signaling events that can be effectively targeted to treat neural disorders. This work is primarily focused on acute neuronal injury, such as stroke, although the results obtained from these studies have broader applications to more chronic/progressive neurodegenerative conditions. Over the last several years, the laboratory has investigated redox and photic regulation of NMDA receptors, excitotoxicity, dopamine oxidation pathways, zinc-mediated neurotoxicity, and Kv2.1 potassium channel facilitated forms of neuronal apoptosis, among other topics.
In addition to his position at Pitt, Elias also holds an adjunct appointment in the Department of Cell Biology and Physiology at Ben Gurion University of the Negev, in Beer Sheva, Israel.
