Cancer-associated fibroblasts(CAFs)remodel the extracellular matrix(ECM)and shape the tumor microenvironment (TME), resulting in immune escape and the promotion of tumor metastasis. Using an orthotopic tumor model of colorectal cancers(CRCs)in mice, we demonstrated that the single-cell RNA sequencing of orthotopic rectal tumors identified a subpopulation of CAFs that modulate the immune response. In this review, we report that understanding the role of CAFs in the TME concerning tumor immunity may lead to future avenues for CAF-targeted therapy.
