However, existing FDA-approved CAR-Ts were limited by low antigen sensitivity, rendering their insufficient targeting to low antigen-expressing cancers. To improve the antigen sensitivity of CAR-Ts, we engineered CARs targeting CD19, CD22, and HER2 by including intrinsically disordered regions (IDRs) that promote signaling condensation. The CARs fused with IDR from FUS, EWS, or TAF15 triggered enhanced membrane-proximal signaling in the CAR-T synapse, which led to an increased release of cytotoxic factors, a higher killing activity towards low antigen-expressing cancer cells in vitro. Moreover, the IDR CAR-Ts induced improved anti-tumor effects in vivo in both blood cancer and solid tumor models. No elevated tonic signaling was observed in IDR CAR-Ts. Together, we demonstrated IDRs as a new tool set to enhance CAR-T cytotoxicity and to broaden CAR-T’s application to low antigen-expressing cancers. Overall design: PBMCs were isolated from mice blood. Human T cells were sorted for library preparation and single cell RNA sequence."],"repository":["ENA"],"additional_accession":[]},"is_claimable":false,"name":"Transcriptomic profiling of IDR CAR-T cells in the CD19 cancer model.","description":"Transcriptomic profiling of IDR CAR-T cells in the CD19 cancer model.","dates":{"last_updated":"2025-09-24","first_public":"2025-09-08"},"accession":"PRJNA1135885","cross_references":{"GEO":["GSE272224"],"taxon":["9606"]}}
