Research Interests:Signal transduction pathways in microglia in response to estrogens and extracellular adenine nucleotides that modulate their production of neurotoxic inflammatory mediators.


Our research interests are in the signal transduction mechanisms governing microglial cell responses to extracellular adenine nucleotides and estrogens, agents that our data suggest may exert neuroprotective effects in the brain following several types of neurotoxic injuries. The role of the MAP kinase pathways in controlling microglial cell production of inflammatory mediators and how hypoxia and/or reoxygenation injury alters their signaling responses to purinergic receptor activation are of primary interest.
