Some researchers prepared an FAP gene-engineered tumor cell-derived exosome-like nanovesicles (eNVs-FAP) vaccine, which not only suppressed tumor growth by enhancing the infiltration of effector T cells in tumor cells and FAPCAFs and reprogramming the immunosuppressive TME, but also facilitated IFN-γ-induced tumor cell ferroptosis [82]. Here, FAP is linked to neoplasm.
