Cancer immunotherapy utilizing cytotoxic T lymphocytes (CTLs) has demonstrated significant promise in clinical applications, but cancer immunosuppressive mechanisms hamper further progress in T cell immunotherapy. Here we show a correlation between cancer cell mitochondria content and their resis...
Small cell lung cancer (SCLC) exhibits profound immunometabolic suppression that impairs antigen presentation and constrains immunotherapy efficacy. Through integrated multi-omics analyses of primary human SCLC tumors, we identified midkine (MDK) as a dominant tumor-secreted driver of immune evas...
