A Tumor‐Boundary Niche Enriched for PD‐1+CD8+T Cells and BTLA+B Cells Drives Resistance to Immunotherapy in NSCLC
ABSTRACT CD8+T cells are central mediators of antitumor immunity, and their functional heterogeneity profoundly influences immunotherapy efficacy. We characterized the spatial distribution of CD8+T cell subsets stratified by PD‐1 expression within the tumor microenvironment (TME) of non‐small cell lung cancer (NSCLC)....
