We confirmed that i.v. injection of Cyt c (5 mg/mouse every other day) caused the selective depletion of cDC1 (including that of XCR1+ migratory cDC1) but no cDC2 cells in the blood, tumor, and tumor-draining lymph nodes from mice bearing MCA205 fibrosarcomas (Fig. S9A-C) or TC-1 lung cancers (Fig S10B-D). Here, MPPE1 is linked to neoplasm.
