Background

Dr. Tzyy-Choou Wu is a professor of pathology, oncology, and obstetrics and gynecology at the Johns Hopkins University School of Medicine. He holds a joint appointment in the Bloomberg School of Public Health Department of Molecular Microbiology and Immunology.

Dr. Wu’s clinical interests include gynecological pathology, cervical cancer, head and neck cancers, and the molecular diagnosis of viral infections.

He and Dr. Chien-Fu Hung also oversee the Cervical Cancer Research Lab, which is working to develop vaccines and immunotherapeutic strategies to prevent and treat human papillomavirus (HPV)-associated cervical cancer.

Dr. Wu earned his M.D. at National Taiwan University College of Medicine before earning both his Ph.D. in molecular virology and his M.P.H. in epidemiology at the Johns Hopkins Bloomberg School of Public Health. He completed a residency in anatomic pathology and a fellowship in gynecologic pathology at Johns Hopkins. He joined the Johns Hopkins faculty as an assistant professor in 1995.

Dr. Wu has published more than 260 academic journal articles, written scores of editorials, reviews and book chapters, and delivered many invited lectures. He also holds a number of patents.

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.

Lab

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

Patents

DNA Vaccine Enhancement with MHC Class II Activators
Patent # US9085638 B2 | 07/21/2015

Methods for treating or preventing hyperproliferating diseases, e.g., cancer, are described. A method may comprise administering to a subject in need thereof a therapeutically effective amount of a nucleic acid encoding an MHC class I and/or II activator and optionally a nucleic acid encoding an antigen.

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.

Nucleic Acid Immunogenic Compositions Encoding Hsp-antigen Chimera
Patent # CA2388045 C | 02/11/2014

The invention provides chimeric nucleic acids encoding a chimeric polypeptide, constructs for expressing these polypeptides both in vitro and in vivo, isolated chimeric polypeptides, pharmaceutical compositions and methods of making and using these compositions. These compositions and methods are particularly useful for stimulating or enhancing the immunogenicity of a selected antigen or stimulating or enhancing a cellular immune response specific for that antigen. The nucleic acid of the invention comprises a first polypeptide domain comprising a carboxy terminal fragment of a heat shock protein (HSP), an Flt-3 ligand (FL), a cytoplasmic translocation domain of a Pseudomonas exotoxin A (ETA dII), or a granulocyte-macrophage-colony stimulating factor (GM-CSF) sequence, and a second polypeptide domain comprising an antigenic polypeptide.
