Invited Academic Seminar Series – Peter Yingxiao Wang- Remote Control of the Genetics within Tumors via Focused Ultrasound for Cancer Immunotherapy (Hybrid Delivery)

March 14, 2023 @ 12:00 pm - 1:00 pm EDT

Focused ultrasound (FUS) can deliver energy safely and noninvasively into tissues at depths of centimeters. We show that the genetics and cellular functions of chimeric antigen receptor T cells (CAR-T cells) within tumors can be reversibly controlled by the heat generated by short pulses of FUS via a CAR cassette under the control of a promoter for the heat-shock protein. In mouse tumor models, locally injected T cells with the inducible CAR and activated via FUS guided by magnetic resonance imaging (MRI) mitigated on-target off-tumor activity and enhanced the suppression of tumor growth, compared with the performance of standard CAR-T cells. Integrated with CRISPR, FUS was also be applied to modulate the genetics and epigenetics of tumor cells, which facilitated and enhanced the efficacy of the CAR T immunotherapy. Therefore, acoustogenetic control of tumor cells and CAR T by FUS may facilitate the design of safer cell therapies.
