Dr. Letai is a Professor of Medicine at Harvard Medical School and Dana-Farber Cancer Institute. He began his studies in apoptosis and hematologic malignancies as a post-doctoral fellow in the laboratory of Dr. Stanley Korsmeyer. He then started his own laboratory at Dana-Farber in 2005 and became an LLS Scholar in 2008. His studies in understanding how BCL-2 family members regulate the cell death pathway of apoptosis were instrumental in the translation of the BCL-2 inhibitor venetoclax to the clinic, where it is now FDA approved for the treatment of chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML). His laboratory has been investigating how immune cells used in cancer immunotherapy use apoptosis pathways to kill cancer cells, and how increasing apoptosis signaling in cancer cells might benefit immunotherapy. He is also investigating how reducing apoptosis signaling in immune cells used for immunotherapy might make them work better in cancer patients.
