Development of an in situ CAR-T cell protocol through optical and PSMA-targeted PET imaging.

ABSTRACT: In situ T cell transfection methods overcome the complexity and high costs associated with conventional chimeric antigen receptor (CAR)-T therapy. However, the in situ CAR-T cell approach operates within the patient's complex immune environment and bypasses preinfusion ex vivo cellular quality controls, necessitating advanced imaging techniques to track immune cell migration and function. Positron emission tomography (PET) can detect biochemical processes in patients and, when combined with a radiotracer specific for the engineered cells, can monitor CAR-T cell trafficking. Herein, we develop an approach for in situ T cell generation, tracking, and functional assessment using anti-CD5-conjugated lipid nanoparticles for codelivering CD19 CAR mRNA (mCAR19) and a prostate-specific membrane an
