Justin Jenson, Ph.D., Postdoctoral Fellow University of Texas Southwestern Medical Center

This CRI Fellowship gives me the freedom and flexibility to tackle a challenging but exciting project that could positively impact human health and help build the foundation for the rest of my career.
Area of Research: All Cancers

To date, most successful treatments with cancer immunotherapy result from activating, enhancing, or otherwise unleashing cells of the patient’s immune system called T cells. One of the chemical coordinators of T cell activation against tumors is type 1 interferon (IFN). Dr. Jenson’s work focuses on an enzyme involved in type 1 IFN signaling called cGAS, which is involved in our immune system’s ability to monitor our bodies for cancer cells.

Specifically, he is seeking to determine the factors that contribute to cGAS activity within tumor cells as well as understand certain alterations cGAS undergoes in the presence of DNA that increase its activity, a process that remains as yet undefined. If Dr. Jenson succeeds, the knowledge his research will yield may lead to new strategies to improve the effectiveness of cancer immunotherapy.
