Overview

Genome-wide screening reveals TP53 mutations enhance CAR-T resistance in B-ALL, suggesting lipid uptake impacts therapy efficacy.

Key Points

  • This research examines how TP53 mutations influence CAR-T cell resistance in B-cell acute lymphoblastic leukemia.
  • Tested CAR-T sensitivity in isogenic B-ALL cell lines with different TP53 statuses.
  • Performed genome-wide CRISPR/Cas9 screening to identify mechanisms of resistance.
  • Assessed lipid metabolism's role using specific inhibitors during CAR-T co-culture.
  • Identified TP53 mutations as a key factor in CAR-T resistance.
  • Found that FATP2 expression correlates with increased lipid uptake and resistance.
  • Demonstrated that inhibiting lipid metabolism enhances CAR-T sensitivity in TP53-mutant B-ALL.
