Research Interest

We seek to understand the cellular and molecular mechanisms of leukocyte recruitment and priming in tumor immunotherapy by utilizing a combination of anti-tumor mAb and yeast-derived polysaccharide b-glucan. This research focuses on tumor immunotherapy mediated by anti-tumor antibodies that bind to tumors and activate complement, and which have been shown to be enhanced by co-administration of yeast-derived b-glucan. Granulocytes were discovered to be effector cells for this combination therapy. We also are attempting to determine the mechanism of action of b-glucan in hematopoietic stem and progenitor cell mobilization and radiation protection.
The second major area of interest in the lab involves the roles of B cells in the regulation of autoreactive T cell activation and tolerance using a murine systemic lupus erythematosus (SLE) model. Knowledge gained from these studies has led us to develop effective vaccines for cancer and infectious diseases.
