Email Profile Print Profile Overview Contact Info & Locations Research Areas Cellular and Molecular Biology Special Interests Research Interests Research focuses on studying the regulation and function of mammalian phospholipase A2 enzymes and the production of lipid mediators of inflammation. Our research focuses on studying cytosolic phospholipase A2alpha (cPLA2), which releases arachidonic acid for production of lipid mediators of inflammation. cPLA2 is potently activated in macrophages infected with microorganisms resulting in production of eicosanoids. This is an early response to microbial infection that initiates acute inflammatory responses. We are studying the role of pattern recognition receptors and the signal transduction mechanisms leading to activation of cPLA2 in macrophages focusing on the role of calcium mobilization and kinase activation. Calcium regulates cPLA2 by binding to an N-terminal C2 domain, which promotes translocation of cPLA2 from the cytosol to membrane for release of arachidonic acid. The role of calcium and phosphorylation of cPLA2 by mitogen-activated protein kinases in regulating its translocation to the forming phagosome during phagocytosis of zymosan is being investigated. A long-term goal is to elucidate the role of cPLA2 and production of eicosanoids in regulating susceptibility to microbial infection.

This survey is about the patient care experience and does not address crucial characteristics like medical decision-making, prescribing the best therapy, and patient outcomes. Responses are measured on a scale of 1 to 5, with 5 being the best score. Learn more about our patient satisfaction survey.
