John W. Greiner

Staff Scientist
Center for Cancer Research
National Cancer Institute
United States of America


Dr. Greiner is a Staff Scientist and Head of the Cytokine Group in the Laboratory of Tumor Immunology and Biology, NCI. He received his Ph.D. in Physiology and Biophysics from West Virginia University, Morgantown, WV. Dr. Greiner's research interests are in cancer vaccines and immune adjuvants. The Cytokine Group studies the interactions of cytokines and T cell checkpoint inhibitors on the different arms of the immune system to optimize antitumor responses to recombinant vaccines and monoclonal antibody therapy. We are working to define novel strategies for the delivery and use of cytokines and T cell checkpoint inhibitors as biologic adjuvants and immunotherapeutics. Additionally, we are involved in the development of new animal models for the analysis of new vaccines and vaccine strategies.
