The aim is to improve CAR T-cell therapy for solid tumors by integrating cytokine signaling into CAR constructs.
Developed a modular CAR engineering strategy incorporating IL-2/IL-15 receptor–derived motifs.
Identified construct S71 through systematic screening for enhanced antitumor activity.
Evaluated S71's effects on T-cell fitness and metabolism in solid tumors.
S71 showed significantly higher antitumor activity compared to other CAR mutants in various tumor models.
S71 improved mitochondrial function in T-cells, supporting durable immune activity.
Enhanced persistence and robust immune memory responses were observed with S71 against solid tumors.
