REPAIRING IMMUNE FUNCTION

Damage-Induced Pyroptotic Cell Death Facilitates Regeneration of the Thymus

As a small but mighty butterfly shaped gland in the chest, the thymus is the training ground for T cells to mature into disease-killing machines in the body. But over time, the thymus wears out from stress, infection and age. Finding ways to help repair it could have broad implications for preventing and treating cancer. Dr. Sinead Kinsella, a researcher in the lab of Dr. Jarrod Dudakov, will present findings on a new way of thymus regeneration in which a cell death process called pyroptosis is critical in releasing large numbers of signaling molecules that can trigger the thymus to repair itself.  Abstract No. 735 (oral presentation) Monday, Dec. 7, 2020: 2:45 p.m. On Twitter: Dr. Sinead Kinsella: @shinkinsella Dr. Jarrod Dudakov: @Dudakov_lab

 

T CELL RECEPTOR THERAPY

The immune system plays a key role in detecting tumor antigens and killing cancer cells. But immune response to tumor antigens varies and is often insufficient to prevent tumor growth and relapse. Fred Hutch physician-scientists have identified specific tumor antigens that can be targeted to trigger a potent immune response. The team is creating immunotherapy using genetically modified T cells, called TCR T-cell immunotherapy, to augment these responses in patients.

Phase I Study of Adoptive Immunotherapy with HA-1-Specific CD8+ and CD4+ Memory T Cells for Children and Adults with Relapsed Acute Leukemia after Allogeneic Hematopoietic Stem Cell Transplantation (HCT): Trial in Progress Dr. Elizabeth Krakow will present a Phase I trial in progress. It uses a T-cell receptor therapy developed by Dr. Marie Bleakley to treat adult and pediatric patients who have relapsed after receiving a stem cell (blood and marrow) transplant for leukemia or other related conditions. Abstract No. 492 (oral presentation) Sunday, Dec. 6, 2020: 2:15 p.m.

A d SF3B1 Neoantigen Is Presented on Primary Malignant Cells and Induced Pluripotent Stem Cell-Derived Hematopoietic Lines

Neoantigens, tiny markers that arise from cancer mutations, flag cells as cancerous and could lead to more targeted precision immunotherapies. But, because hundreds of mutations exist on a tumor, targeting the right neoantigen is crucial to trigger an immune response. Dr. Melinda Biernacki, working with the Hutch’s Dr. Marie Bleakley, will present findings that identify a specific neoantigen, SF3B1, present in Myelodysplastic Syndromes (MDS), secondary acute myeloid leukemia (AML) and advanced chronic lymphocytic leukemia (CLL), as a promising target for treatment with immunotherapy. Abstract No. 3265 (poster presentation) Monday, Dec. 7, 2020, 7:00 a.m. – 3:30 p.m.

At Fred Hutchinson Cancer Research Center, home to three Nobel laureates, interdisciplinary teams of world-renowned scientists seek new and innovative ways to prevent, diagnose and treat cancer, HIV/AIDS and other life-threatening diseases. Fred Hutch’s pioneering work in bone marrow transplantation led to the development of immunotherapy, which harnesses the power of the immune system to treat cancer. An independent, nonprofit research institute based in Seattle, Fred Hutch houses the nation’s first National Cancer Institute-funded cancer prevention research program, as well as the clinical coordinating center of the Women’s Health Initiative and the international headquarters of the HIV Vaccine Trials Network.
