Transforming growth factor {beta} induced as a novel secreted immune checkpoint counterinhibiting human tumor-associated T cells

Journal for ImmunoTherapy of Cancer | |

Background <p>We investigated the hypothesis that transforming growth factor &beta; induced (TGFBI), an extracellular matrix protein secreted in the microenvironment of several tumors, can act as a secreted immune checkpoint (sIC) that contributes to the suppression of human antitumor T cell responses.</p> Methods and results <p>Serum TGFBI concentrations, measured by ELISA, were significantly higher in patients with colorectal cancer (CRC)…
