Epigenetic remodeling in sarcoma promotes T-cell infiltration via modulation of the Hippo pathway

Journal for ImmunoTherapy of Cancer | |

Background <p>Insufficient T-cell infiltration limits the effectiveness of immunotherapy in sarcoma, yet the tumor-intrinsic mechanisms that govern immune exclusion remain poorly defined.</p> Methods <p>By integrating patient-derived ex vivo sarcoma spheroids with autologous expanded tumor-infiltrating lymphocytes and an in vivo metastatic osteosarcoma model, antitumor immune regulation by histone modifications was examined.</p> Results <p>Histone H3 lysine 27 acetylation (H3K27ac) was identified as…
