Cerebroscience

Basic and preclinical translational research is being conducted in the areas of cerebrovascular physiology and cerebral ischemic injury arising from ischemic and hemorrhagic stroke, cardiac arrest, and head injury. Emphasis is on the use of in vivo models of integrated systems physiology and pathophysiology and on the use of in vitro systems to gain mechanistic insights.

Major areas of focus include signaling of cell death pathways, activation of different phospholipase A2 enzymes, cyclooxygenase metabolites of arachidonic acid and their actions on specific prostaglandin receptors, effect of sex hormones, metabolism of hemoglobin and iron, potential therapy with alternative antioxidant nutrients, and mechanisms of tolerance from ischemic preconditioning. In addition to investigating potential therapies to protect neurons, strategies to rescue ischemic brain by enhancing vascular dilation or by using hemoglobin-based oxygen carriers are being explored.

A major topic in cerebrovascular physiology is unraveling the mechanisms that couple an increase in cerebral blood flow to neuronal activity. Emphasis in the laboratory has been on astrocyte-derived vasodilators. Another area of cerebrovascular research is the development of indices of autoregulatory vasoreactivity with non-invasive monitoring modalities such as cerebral oximetry. Preclinical and clinical validation of these indices is being conducted with the goal of providing real-time information for optimizing clinical management of cerebral perfusion pressure.

Other areas of investigation include use of hypertonic agents to reduce brain swelling, advanced electrophysiological monitoring of postischemic brain, deep brain stimulation for the treatment of seizures, mechanisms of neonatal hypoxic-ischemic encephalopathy, and therapies to extend the therapeutic time window for hypothermia.
