This PDF file includes:

  • Fig. S1. CAR4 and CAR8 cells demonstrate comparable in vivo efficacy at low doses against murine ALL, E2aPbx.
  • Fig. S2. The presence of both TCR and CAR antigens diminishes efficacy of CAR8 but not CAR4 cells at 14 days.
  • Fig. S3. TCR stimulation induces down-regulation of CAR expression.
  • Fig. S4. Up-regulation of PD-1 and Lag3 expression is dependent on CAR stimulation.
  • Fig. S5. CAR8 cells are capable of endogenous B cell clearance despite ineffective leukemia clearance.
  • Fig. S6. In vitro CAR4 and CAR8 cell cytokine profiles when stimulated through TCR, CAR, or both receptors.
  • Fig. S7. Gene list for pathways/gene sets from CAR4 and CAR8 cells stimulated through CAR, TCR, or both receptors.
