TapImmune taps into the immune system to take out autoimmune disorders. Its research is primarily focused on the biological TAP system, which triggers an immune system response in cells. The TAP system shuts down in many cancer tumor cells, but the company is developing a vaccine to restore the immune function. TapImmune is also researching a vaccine adjuvant product designed to enhance the effectiveness of existing and new infectious disease vaccines. The company also has technologies that could be used to identify or screen drugs for potential effectiveness in treating cancers and viral and infectious diseases.
