    Research Summary

    Dr. Wu’s research focuses on human papillomavirus (HPV) vaccine development.

    He has created a unique preclinical murine tumor model that expresses HPV-16 oncogenic proteins (E6 and E7) and simulates specific molecular events in the progression of HPV+ precancerous lesions (CIN 3) to invasive cancer.

    This model has been widely used and tested by researchers worldwide for HPV vaccine development.

    Dr. Wu has focused on identifying immunotherapeutic and vaccine approaches to enhance antigen processing and presentation by dendritic cells. These include intracellular targeting and spreading strategies aimed at preventing and treating cervical lesions and cancers. Intracellular targeting directs antigens to different subcellular locations to enhance antigen processing and presentation.

    Intercellular spreading helps antigens distribute to neighboring cells by taking advantage of unique intercellular transport properties that allows for an increase in the amount of antigen presented to effector cells.

    Dr. Wu has created an innovative approach that combines both antigen-specific immunotherapy and anti-angiogenesis to treat HPV E7-expressing tumors.

    The impressive preclinical data derived from these studies have led to several clinical trials that are either currently under way or will soon commence. The continued development of these strategies will facilitate the development of vaccines that generate a potent immune response and antitumor effect against cervical cancer.

    Dr. Wu is also actively involved with investigating mechanisms of immune evasion of tumors, identifying new tumor-specific antigens and applying vaccine strategies to other cancer systems with characterized tumor-specific antigens.


    The Cervical Cancer Research Lab of Drs. T-C Wu and Chien-Fu Hung has a multi-part mission to:

    • Create the most effective cervical cancer vaccine for the prevention and treatment of human papillomavirus-associated malignancies
    • Extend the application of the principles and strategies that we use for HPV vaccine development in order to create vaccines that target other cancers with defined tumor antigens
    • Develop innovative immunological assays for human papillomavirus vaccine clinical trials
    • Serve as an environment for the education of research technicians, graduate students and undergraduate students

    RNA Interference That Blocks Expression of Pro-Apoptotic Proteins Potentiates Immunity Induced by DNA and Transfected Dendritic Cell Vaccines
    Patent # US9011866 B2 | 04/21/2015

    An immunotherapeutic strategy is disclosed that combines antigen-encoding DNA vaccine compositions combined with siRNA directed to pro-apoptotic genes, primarily Bak and Bax, the products of which are known to lead to apoptotic death. Gene gun delivery (particle bombardment) of siRNA specific for Bak and/or Bax to antigen-expressing DCs prolongs the lives of such DCs and lead to enhanced generation of antigen-specific CD8+ T cell-mediated immune responses in vivo. Similarly, antigen-loaded DC's transfected with siRNA targeting Bak and/or Bax serve as improved immunogens and tumor immunotherapeutic agents.
