The major areas of investigation are: endothelial cell signaling, particularly lymphatic endothelium; interactions between hepatitis C and HIV envelope proteins; the role of HIV tat in cell signaling; the pathogenesis of hematopoietic progenitor cell apoptosis in HIV infected hosts; isolation and characterization of adult hematopoietic stem cells; role of cannabinoids in immunology. In addition, we are exploring new drugs for lymphoma.
