With stroke a major cause of ICU admissions and hospital mortality, Dr. Sapirstein focuses his research on the role of phospholipases A2 and their lipid metabolites in brain injury. He and his group are evaluating the role of the cytosolic, Group V, and Group X PLA2s in models of stroke and excitotoxicity and are investigating the function of PLA2s in cerebrovascular regulation. Both areas of research are conducted with in vivo and in vitro models.

Dr. Sapirstein and his colleagues believe that inhibitors of the PLA2 enzymes are likely to have several important clinical uses. (Major pharmaceutical companies are currently developing and trialing such drugs.) They are particularly excited by their discovery that cPLA2 is essential for the early electrophysiologic changes that occur in hippocampal CA1 neurons following exposure to N-methyl-d-aspartate (NMDA) (Shen Y, Kishimoto K, Linden, DJ, Sapirstein A. Cytosolic phospholipase A2 alpha mediates electrophysiologic responses of hippocampal pyramidal neurons to neurotoxic NMDA treatment. Proc Natl Acad Sci U S A 104:6078, 2007), a finding that has profound implications regarding the possible uses of selective cPLA2 inhibitors following acute neurologic injury. Although they are working with models of stroke in mice, their findings may be broadly applicable to a variety of neurologic disorders. PLA2s also have been implicated in the pathogenesis of aspiration lung injury during general anesthesia and in reactive airway responses.

In the long term, Dr. Sapirstein hopes to establish the potential for clinical inhibition of PLA2 enzymes in the treatment of acute and chronic neurologic diseases and injuries. He also hopes to use in vivo imaging and lipid analysis to delineate specific roles for lipid species in modulating excitotoxicity and cerebrovascular responses.
