Necroptosis-driven T cell activation promotes IL-6-mediated PD-L1 upregulation in cholangiocarcinoma cells: IL-6 gene signature as a biomarker for chemo-immunotherapy response

This study highlights that necroptosis shapes the tumor immune microenvironment by promoting T cell activation and IL-6-mediated PD-L1 upregulation in CCA cells. These findings support the integration of necroptosis-based therapies with ICIs as a sequential chemo-immunotherapy strategy. Additionally, the identified IL-6 signaling-related gene signature may serve as a biomarker for patient stratification and personalized treatment in CCA.
