Abstract Background We investigated the role of tumor cell-intrinsic PD-L1 signaling in epithelial−mesenchymal transition (EMT) non-small-cell lung cancer (NSCLC) and EMT as a predictive biomarker for immune checkpoint inhibitor (ICI) therapy. Methods PD-L1-overexpressing or PD-L1-knockdown NSCLC cells underwent RNA-seq phenotype assessment. Mouse LLC were injected into nude mice. Two cohorts patients with undergoing ICI therapy analyzed. Results showed that pathways enriched PD-L1-high...
The importance of mitochondrial function in macrophages is well established. Alveolar (AMs), the tissue-resident (TRMs) lung, are particularly dependent on mitochondria-driven oxidative phosphorylation (OXPHOS) to support their functions and maintain homeostasis. However, specific genes pathways that regulate OXPHOS AMs remain unclear. In this study, we investigated role CR6-interacting factor 1 (CRIF1), a regulator, as key specifically modulates metabolic fitness maintenance AMs. Using...
Some patients with non-small-cell lung cancer (NSCLC) benefit from immune checkpoint inhibitors (ICIs) despite programmed death-ligand 1 (PD-L1) expression. To address the mechanism of ICI resistance in PD-L1-positive NSCLC, we investigated role tumor-cell-intrinsic function PD-L1 interleukin (IL)-6-mediated immunosuppression. Cohorts NSCLC treated and public datasets were analyzed. PD-L1-overexpressing PD-L1-knockdown cells submitted to RNA-seq, vitro analyses, chromatin...
Abstract Type-2 innate lymphoid cells (ILC2s) exhibit dual functions in cancer, both promoting and inhibiting tumor growth by regulating anti-tumor immune responses. Elucidation of the precise mechanisms which ILCs regulate adaptive responses could support development improved immunotherapeutic approaches. Here, we revealed that ILC2s possess capacity to internalize, process, present exogenous antigen on major histocompatibility complex class I (MHC I) molecules, along with costimulatory...

Abstract The expression of PD-L1 on tumor cells (TC) is used as an immunotherapy biomarker in lung cancer, but heterogeneous intratumoral often observed. To better understand heterogeneity the cancer microenvironment, we performed proteomic and whole-transcriptomic digital spatial profiling analyses TCs immune (IC) spatially matched areas based status microenvironment. We validated our findings using IHC, data from Cancer Genome Atlas, cohorts. ICs with high showed more features, indicative...
