SMAD7 drives natural killer cell antitumor activity through canonical TGF-{beta} blockade and non-canonical transcriptional activation of STAT5A

Journal for ImmunoTherapy of Cancer | |

Background <p>Natural killer (NK) cells are key effectors in antitumor immunity, yet their function is markedly suppressed by transforming growth factor-&beta; (TGF-&beta;) in the tumor microenvironment. SMAD7 is an established intracellular antagonist of TGF-&beta; signaling, but its specific role within NK cells remains poorly defined.</p> Methods <p>The clinical relevance of SMAD7 in tumor-infiltrating NK cells was evaluated via integrative analyses…
