NFAT5-based NCtag CAR-T cells

**NFAT5-based NCtag CAR-T cells** are an engineered cell therapy where T cells are modified to express a chimeric antigen receptor (CAR) incorporating NFAT5-responsive elements and NCtag technology. NFAT5 (nuclear factor of activated T-cells 5), a transcription factor responsive to hyperosmotic stress and involved in T_H17 cell differentiation and pro-inflammatory macrophage activation, drives conditional CAR expression or signaling upon activation. NCtag likely refers to a novel chimeric tag or switch mechanism enabling precise control of CAR-T function, potentially reducing off-tumor toxicity. This approach aims to enhance CAR-T specificity and safety for cancer immunotherapy by leveraging NFAT5's immune-regulatory role in pathogenic responses.
