A cell aging pattern identifies COMP-positive support cells linked to CD8+ T-cell exclusion through a COMP-CD47 pathway in colorectal cancer

Updated

Abstract

Resistance to immunotherapy in colorectal cancer is linked to an immunosuppressive tumor microenvironment characterized by specific cellular senescence-related genes.

  • Cancer-associated fibroblasts are identified as key regulators of the tumor microenvironment in colorectal cancer.
  • Cellular senescence and the senescence-associated secretory phenotype may drive the activity of these fibroblasts.
  • A prognostic signature based on differentially expressed cellular senescence-related genes was developed and validated in independent cohorts.
  • Integrative analyses revealed associations between the prognostic signature and immune cell infiltration in colorectal cancer.
  • Validation of findings at the protein level was conducted using techniques such as multiplex immunofluorescence.
