Tumor stroma is a key component of the immunosuppressive tumor microenvironment in pancreatic ductal adenocarcinoma (PDAC). Here, in preclinical PDAC models, the authors show that depletion of FAP-expressing cancer associated fibroblasts with FAP-targeted CAR T cells results in a loss of the integrity of the desmoplastic matrix, rendering tumors more susceptible to sequential treatment with mesothelin-targeted CAR-T cells.
