Abstract

Chimeric antigen receptor–modified (CAR-modified) T cells have shown promising therapeutic effects for hematological malignancies, yet limited and inconsistent efficacy against solid tumors. The refinement of CAR therapy requires an understanding of the optimal characteristics of the cellular products, including the appropriate composition of CD4 + and CD8 + subsets. Here, we investigated the differential antitumor effect of CD4 + and CD8 + CAR T cells targeting glioblastoma-associated (GBM-associated) antigen IL-13 receptor α2 (IL13Rα2). Upon stimulation with IL13Rα2 + GBM cells, the CD8 + CAR T cells exhibited robust short-term effector function but became rapidly exhausted. By comparison, the CD4 + CAR T cells persisted after tumor challenge and sustained their effector potency. Mixing with CD4 + CAR T cells failed to ameliorate the effector dysfunction of CD8 + CAR T cells, while surprisingly, CD4 + CAR T cell effector potency was impaired when coapplied with CD8 + T cells. In orthotopic GBM models, CD4 + outperformed CD8 + CAR T cells, especially for long-term antitumor response. Further, maintenance of the CD4 + subset was positively correlated with the recursive killing ability of CAR T cell products derived from GBM patients. These findings identify CD4 + CAR T cells as a highly potent and clinically important T cell subset for effective CAR therapy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
