Dr. Kranzusch is investigating how the signaling molecule cGAMP is controlled within cells, research that is critical for the rational design of next-generation anti-cancer immunotherapies. cGAMP carries immunity-stimulating signals between the enzyme cGAS and the receptor STING, which can spread rapidly from cell to cell to activate a widespread antitumor immune response. Researchers in the Kranzusch laboratory are studying the mechanism and downstream immune effects of cGAMP regulation, including identifying the key biological factors involved in cGAMP degradation. Dr. Kranzusch earned his PhD from Harvard University and completed postdoctoral studies at University of California, Berkeley. In 2016 he started as an Assistant Professor of Microbiology at Harvard Medical School and the Dana-Farber Cancer Institute. The Kranzusch Lab uses a biochemical and structural biology approach to understand the immune response to cancer.
