CELL INTELLIGENCE · 肿瘤细胞治疗研究

While chimeric antigen receptor T-cell (CAR-T) therapy has revolutionized the treatment of hematological malignancies, there are significant hurdles to overcome, such as antigen escape, T-cell exhaustion, limited persistence in the body, severe toxicities, manufacturing complexity, high costs, and low effectiveness in the treatment of solid tumors. There are many reviews describing novel CAR-T technologies, the evidence strength, clinical maturity and unmet translational risks of each are largely included in those reviews.

This review highlights the ways in which next-generation engineering increases the safety, efficacy and programmability of CAR-T. The primary and authoritative clinical, regulatory and preclinical evidence on recent advances from 2022 to 2026 was carefully evaluated, including the quality and quality control of the evidence for each strategy.

New innovations are Armored CARs, dual-target and logic-gated/synNotch systems, universal and switchable platforms, CRISPR/Cas9 and base/prime editing, allogeneic CAR-Ts, non-viral manufacturing, and lipid-nanoparticles in vivo CAR-T generation.

Additionally, the engineering and combination approaches for the treatment of solid tumors with checkpoint inhibitors, radiotherapy, oncolytic viruses, nanotechnology, and artificial intelligence are discussed. An evidence-to-maturity framework separates the clinically proven methods from the emerging technologies and highlights some of the critical translation hurdles related to safety, immunogenicity, durability, manufacturing and scale.

Precision Immunotherapy is becoming more and more possible with the next generation CAR-T engineering, however the validation and translational optimization of these cells is dominant to their eventual clinical use.
