Article Description

Immune synapse (IS) formation determines T cell antitumor activity. Here, we present a protocol for characterizing the IS formation between chimeric antigen receptor (CAR) T cells and tumor cells by measuring the IS size and calcium flux by live-cell imaging. We describe steps for CAR T cell manufacturing, sample preparation, image acquisition, and data analysis. For complete details on the use and execution of this protocol, please refer to Chockley et al., 1 Ibanez et al., 2 and Zoine et al. 3
