Spatial and Single-Cell Transcriptomics Reveal a Cancer-Associated Fibroblast Subset in HNSCC That Restricts Infiltration and Antitumor Activity of CD8+ T Cells

Abstract

Spatial analysis identifies IFN-induced MHC-IhiGal9+ CAFs that form a trap for CD8+ T cells, providing insights into the complex networks in the tumor microenvironment that regulate T-cell infiltration and function.
