Our laboratory studies the regulation of lymphocyte activation. We employ both in vitro (cell culture) and in vivo (transplantation with mouse models) methods in our studies. Our current research focuses upon attempts to reproduce the immunology of the tumor microenviroment in vitro. Many tumors have all of the necessary immunological components for an immune response. However, these cells, while in the tumor, remain "shut off" or suppressed. We can reproduce these conditions in vitro and have developed a screening system for tests of relieving this suppression. The students working in the lab are investigating the immunobiology of this suppression and ways to turn the immune cells back "on". Students present their research at regional and national meetings and gain valuable experience that has led to their placement in graduate and medical schools and the pharmaceutical industry.
