Abstract

Cyclic peptide-based chimeric antigen receptor (CAR) T cells provide a compact, engineerable recognition modality that can mediate antigen-dependent cytotoxicity while exhibiting an attenuated cytokine secretion profile, supporting the development of potentially safer immunotherapies for solid tumors. Here, we present a comprehensive workflow spanning CAR construct design and generation through in vitro and in vivo functional evaluation. The protocol includes the generation of Jurkat NFAT reporter cell lines and luciferase-expressing tumor target lines, which are widely used in different assays. Together, these standardized readouts enable rigorous, objective comparison of CAR T cell efficacy and safety across tumor models.
