In this work, we design and screen four anti-GBM chlorotoxin (CLTX)-CAR constructs with T or neutrophil-specific signaling domains by knocking them into the AAVS1 safe harbor locus of hPSCs via CRISPR/Cas9-mediated homologous recombination and identified an optimized CAR, composed of a 36-amino acid GBM-targeting CLTX peptide27, a CD4 transmembrane domain and a CD3ζ intracellular domain, for neutrophil-mediated tumor-killing. Here, CD247 is linked to glioblastoma.
