    Pan-Cancer Proteogenomics Characterization of Tumor Immunity

    To better understand immune cell surveillance and diverse immune evasion responses in tumor tissues, researchers comprehensively characterized the immune landscape of more than 1,000 tumors across ten different cancers using CPTAC pan-cancer proteogenomic data.

    Immune Heterogeneity in Small-Cell Lung Cancer and Vulnerability to Immune Checkpoint Blockade

    Investigators conducted transcriptomic analyses and non-negative matrix factorization on 271 pre-treatment patient tumor samples from IMpower133 and identified four subsets with general concordance to previously reported small-cell lung cancer subtypes.

    Stem-Like Progenitor and Terminally Differentiated TFH-Like CD4+ T Cell Exhaustion in the Tumor Microenvironment

    Using single-cell sequencing and mouse models, researchers showed that CXCL13, highly expressed in tumor-infiltrating exhausted CD8+ T cells, induced CD4+ follicular helper T (TFH) cell infiltration, contributing to anti-tumor immunity.

    Dickkopf-1 Is an Immune Infiltration-Related Prognostic Biomarker of Head and Neck Squamous Cell Carcinoma

    The authors examined how Dickkopf-1 (DKK1) expression varied across different tumor and normal tissues. They investigated the association between DKK1 mRNA expression and clinical outcomes.
