Humans may sustain a variety of forms of acute central nervous system injury including ischemia, trauma, vasospasm, and perinatal hypoxemia. The Multidisciplinary Neuroprotection Laboratories is dedicated to examining the pathophysiology of acute brain and spinal cord injury with particular reference to disease states managed in the perioperative or neurointensive care environments. Rodent recovery models of cerebral ischemia, traumatic brain injury, cardiopulmonary bypass, subarachnoid hemorrhage, spinal cord ischemia, and perinatal hypoxia have been established with requisite control of relevant physiologic variables. Experimental protocols examine the response of brain to these insults and seek to define appropriate therapeutic interventions. Our work examines the role reactive oxygen species in CNS injury with emphasis on how pharmacologic or genetic variants modulate these processes. Effects of altered synthesis of superoxide dismutase and apolipoprotein E are investigated in transgenic/knock out mice. Outcome studies allow definition of efficacy of pharmacologic agents including superoxide dismutase mimetics, PARP-1 inhibitors, hepatocyte growth factor mimetics, recombinant apolipoprotein E and its peptide fragments, SNO-hemoglobin, and anesthetics on histologic and behavioral recovery from ischemic/traumatic insults. Recent focus has been on SUMOylation responses of neural tissue to ischemic stress. Neurochemical, immunohistochemical, molecular biologic, genomic, and proteomic techniques are used to define the mechanistic basis of observations made in outcome studies. Primary neuronal/glial cultures, organotypic hippocampal slices and immortalized transfected human cell lines are used investigate mechanistic interactions between pharmacologic agents and metabolic stresses.
