Collagen-binding IL-12-armored STEAP1 CAR-T cells for advanced prostate cancer (AACR 2026) - "The CAR-T therapy generated durable anti-tumor immune memory to STEAP1 and other antigens. Our findings suggest that CBD fusion can localize potent but toxic immunomodulators such as IL-12 to the tumor site, offering a promising strategy to improve the safety and effectiveness of CAR-T therapies for solid tumors."

Collagen-binding IL-12-armoured STEAP1 CAR-T cells reduce toxicity and treat prostate cancer in mouse models. (PubMed, Nat Biomed Eng) - "In addition, human CBD-IL-12-armoured CAR-T cells showed potent anti-tumour efficacy in a 22Rv1 xenograft while reducing circulating IL-12 levels compared with unmodified IL-12-armoured CAR-T cells. CBD fusion to potent payloads for CAR-T therapy may remove obstacles to their clinical translation towards elimination of solid tumours."

Engineering Next-Generation STEAP1 CAR T Cells: Development and Optimization for Enhanced Anti-Tumor Efficacy in Prostate Cancer (PCF 2024) - "Our research advances STEAP1-BBζ CAR-T cell therapy by addressing challenges such as antigen escape and functional exhaustion. Optimized PSMA CAR T cells exhibit enhanced anti-tumor efficacy, supporting the development of dual-targeting PSMA-STEAP1 CAR T cells. Additionally, our in vitro model and CRISPR screen identified genetic modifications that enhance metabolic fitness and CAR T cell activity."
