Tumor immune microenvironment facilitates resistance to KRAS G12C inhibitor sotorasib by altered PD-L1 expression.

Journal for ImmunoTherapy of Cancer | |

Background <p>Acquired resistance to KRAS G12C inhibitor sotorasib remains a critical challenge in non-small cell lung cancer treatment. A deeper, rational understanding of resistance mechanisms can enable the development of therapeutic strategies to overcome resistance.</p> Methods <p>We established a syngeneic resistant model after prolonged AMG-510 treatment in C57BL/6 mice. In addition, the in vitro co-culture model and multiple methods including…
