Targeting a candidate stromal immune checkpoint: a cellular senescence signature identifies COMP⁺ cancer-associated fibroblasts associated with CD8⁺ T-cell exclusion via a predicted COMP-CD47 axis in colorectal cancer.
INTRODUCTION Resistance to immunotherapy in colorectal cancer (CRC) is closely linked to an immunosuppressive tumour microenvironment (TME), in which cancer-associated fibroblasts (CAFs) are key regulators. Cellular senescence and the senescence-associated secretory phenotype (SASP) are increasingly recognised as drive...
