AI Summary: Researchers engineered CAR‑T cells to secrete VEGF‑neutralizing single‑chain antibodies, improving infiltration and antitumor activity against solid tumors in preclinical models. By locally neutralizing VEGF, the approach remodels the tumor microenvironment and enhances CAR‑T efficacy, offering a plausible strategy to overcome the long‑standing barrier of poor CAR‑T performance in solid cancers.
