Cystine Restriction Alleviates T Cell Exhaustion and Enhances CAR-T Cell Potency
Targeting nutrient scarcity in tumors restores CAR-T cell strength, potentially extending this therapy to solid cancers.
This Cancer Research study demonstrates that restricting cystine availability in the tumor microenvironment reduces T cell exhaustion and potentiates CAR-T killing in solid tumor preclinical models. This metabolic approach offers a novel combinatorial strategy to overcome a key limitation—T cell exhaustion—and extend CAR-T therapy utility to solid tumor indications.
