The research aims to understand how specific subsets of cancer-associated fibroblasts (CAFs) influence immune exclusion in fibrotic colorectal cancer.
Utilized orthotopic in vivo tumor models combined with spatial and single-cell transcriptomic analyses.
Analyzed both human and murine colorectal cancers to identify CAF-mediated mechanisms.
Performed fibroblast-specific deletion of Thbs2 and monitored the resulting immune cell infiltration.
Matricellular protein THBS2 was found to be highly expressed in matrix CAFs at the tumor front.
Deletion of Thbs2 significantly increased CD8+ T-cell infiltration within tumors.
THBS2 suppressed the production of CXCL9/10, limiting the recruitment of CXCR3+ CD8+ T cells, confirming its role in immune exclusion.
