We engineered CAR19-T cells with overexpression of wild-type CXCR4 (CAR19/CXCR4<sup>WT</sup>-T) or gain-of-function CXCR4 S338X mutant (CAR19/CXCR4<sup>S338X</sup>-T).

Upon engagement with CXCL12, CAR19/CXCR4<sup>S338X</sup>-T cells, but not CAR19/CXCR4<sup>WT</sup>-T cells, displayed significantly increased activation of ERK1/2 and AKT signaling pathways, as well as elevated transcription of TNF-α, IFN-γ, granzyme B, CDK6, and BCL2A1, along with strengthened effector functions, chemotaxis, and activation of anti-apoptotic pathways. Furthermore, CAR19/CXCR4<sup>S338X</sup>-T cells demonstrated significantly improved migration to and retention in the BM accompanied by increased CD45RA<sup>+</sup>CCR7<sup>+</sup> memory T cell populations, which correlated with enhanced anti-leukemic effects following injection into B-ALL-bearing mice.

The mechanism through which YAP/TAZ-high cells evade ferroptosis during cancer progression remains unclear. Here, we showed that YAP/TAZ-low lung cancer cells confer durable ferroptosis resistance to neighboring YAP/TAZ-high cells through a non-cell-autonomous mechanism. Using murine lung carcinoma cell coculture models, we demonstrated that transient exposure to YAP/TAZ-deficient cells induces a stable, contact-independent ferroptosis-resistant state in wild-type (WT) cells, enhancing their metastatic seeding capacity in vivo. This adaptation is mediated by the upregulation of <i>Gch1</i>, which encodes GTP cyclohydrolase 1 and suppresses ferroptosis via the synthesis of the antioxidant metabolite tetrahydrobiopterin (BH4). GCH1 overexpression alone was sufficient to confer ferroptosis resistance in WT cells, whereas conditioned medium from YAP/TAZ-deficient cells replicated this effect, indicating that a soluble factor is involved in <i>Gch1</i> induction. Importantly, the genetic deletion of <i>Gch1</i> in YAP/TAZ-deficient cells abolished their ability to protect WT cells, confirming its essential role in this intercellular program.
