CD4 T cell depletion increases memory differentiation of endogenous and CAR T cells and enhances the efficacy of Super2 and IL-33-armored CAR T cells against solid tumors
Unarmored TRP-1-specific or NKG2D CAR T cells have intrinsic stem-like properties and differentiate into memory T cell subsets but are non-protective against primary or secondary tumors. S233 cytokine armoring alone or with CD4 depletion improved effector responses but limited CAR memory T cell generation. S233-armored CAR T cells or CD4 depletion therapy induced endogenous tumor-specific T<sub>CIRC</sub> and T<sub>RM</sub> T cells, but the combination potentiated endogenous memory T cell generation and resulted in improved protection against B16F10 rechallenge.
