Project Overview

We propose a novel method of delivering pharmacological agents, such as chemotherapeutic compounds, to cancer cells through specific targeting by an adenovirus. We aim to functionalize viruses with antibodies or other targeting methods such that they specifically infect cancer cells and deliver the attached pharmacological cargo.

Background Information

Cancer

  • Cancer is one of the leading causes of death throughout the world.
  • A major obstacle is cancer treatment is the lack of specificity - drugs attack cancerous cells, but they attack healthy cells as well
  • Tumor cells over-express certain cell surface receptors, and many antibodies have been developed against a wide array of these receptors (e.g. CD25 in T cell lymphoma and CD22 in B cell lymphoma)

Viruses

  • Huge variety - can infect all living things

Cancer Drugs

Research Problem and Goals

Project Details and Methods

Linking drug to virus

Modifying specificity of virus

Predicted Outcomes

If all goes well, our virus should be able to deliver cancer drugs specifically to cancerous cells.

This study used an adenovirus to deliver gene therapy to ovarian cancer cells. While we wish to use drug treatment instead, this virus as a vector for delivery is promising.

This study examined the success of utilizing the Semliki Forest Virus to treat mouse tumor models. The results were very good, as tumor growth rate drastically decreased.
