An engineered interleukin-11 decoy cytokine as a cancer therapeutic
Abstract/Contents
- Abstract
- Cytokines are key signaling molecules in the body and can be exploited by cancer to drive unregulated growth. Chapter 1 focuses on the role of engineered cytokines as therapeutics and their benefits and drawbacks compared to more traditional antibody therapeutics. Chapter 2 focuses on the interleukin (IL)-6 family cytokine, IL-11, which has been shown to be highly expressed in lung adenocarcinoma among other cancer types. As the main goal of this thesis, an engineered high affinity IL-11 antagonist was developed using yeast surface display and directed evolution. This IL-11 variant binds with high affinity to human and mouse IL-11 receptor while lacking binding to the signaling co-receptor gp130. Furthermore, the engineered IL-11 variant potently blocks downstream phospho-STAT3 signaling in cancer cells and significantly reduced tumor growth in a xenograft mouse model of lung cancer. Chapter 3 describes additional efforts to develop a cross-reactive IL-11 antibody that could be developed as a parallel therapeutic approach to the engineered IL-11 cytokine. This antibody work provides a starting point for further antibody campaigns against IL-11 and highlights some of the benefits that engineering cytokines have over antibodies.
