Low CAR T Cell Therapy (IMAGE) Purdue University Caption A graphic depicting the activation and inactivation of CAR T cells through a small molecule adaptor is shown. Philip S. Low, Purdue's Ralph C. Corley Distinguished Professor of Chemistry and director of the Purdue Center for Drug Discovery, and graduate student Yong Gu Lee led a team that designed new engineered CAR T cells that must be activated and targeted by a small molecule adaptor before they can kill cancer cells. The system has the potential to control the engineered cells to overcome existing limitations in CAR T-cell therapy.
