Implication

CRISPR screening enhances tumor responses in acute lymphoblastic leukemia and chronic lymphocytic leukemia, suggesting promising gene targets for CAR T-cell therapy.

Key Points

The aim is to identify gene targets that enhance the efficacy of CAR T-cell therapy in leukemia patients.
CRISPR-Cas9 library designed to target 180 genes with multiple sgRNAs per gene.
Healthy donor T cells were gene-modified and tested in vitro and in vivo.
Impact assessed through chronic stimulation assays and immunodeficient xenograft models.
Identified genes that enhanced CAR T-cell proliferation and effector function based on in vitro and in vivo screening.
Mice with edited CAR T-cells displayed improved survival and reduced tumor burden compared to controls.
Top candidates include genes associated with cell migration and cell cycle regulation.
