MRC1 and neoplasm: Strikingly, higher frequencies of tumor-infiltrating Clec-12α+ or DEC-205+ cDC1s were associated with a better clinical outcome as indicated by longer PFS in patients, whereas higher proportions of tumor-infiltrating CD206+ cDC1s were linked with a poor survival even worse when associated with low frequencies of tumor-infiltrating Clec-12α+ and DEC-205+ cDC1s (Figure 7C).
