Description of Itmat Expertise

1) Enhancing the specificity and efficacy of genetically-redirected T cells
2) Developing mechanisms to render T cells resistant to the tumor microenvironment
3) Improving the processes of engineering cells for infusion into patients
4) Interrogating the starting materials and cellular infusion products for key markers of potency

Description of Research Expertise

Our research focuses on developing cellular-based immunotherapy for the treatment of leukemia, lymphoma, myeloma, melanoma, glioblastoma, pancreatic cancer and other malignancies. Studies in the group are directed toward enhancing the specificity and efficacy of genetically-redirected T cells, developing mechanisms to render T cells resistant to the immunosuppressive tumor microenvironment and improving the processes of engineering cells for infusion into patients. We also interrogate cellular products for key markers of potency using biochemical, molecular as well as cell-based assays. Our long-term goals include the 1) development of novel methodologies using adoptive T cell-directed approaches, to enhance patient immunity against cancer and 2) generation of comprehensive, quality-driven platforms to predict as well as evaluate the impact of experimental treatments on patient biology/the disease to allow for a rational and data-driven iterative cycle of translational research. As part of the Center for Advanced Cellular Therapeutics, we closely interact with other scientists, clinicians, study coordinators and an active clinical trials research program to translate laboratory insights into safe and effective cancer treatments.
