CD1C and leukemia: Studies on large cohorts using cDC-specific functional markers such as CLEC9A, CLEC10A, XCR1, and CD1c along with stringent gating strategies are needed to provide clarity on circulating cDC phenotype and function in the different types of leukemias, as the overwhelming majority of published studies focused on leukemic or monocyte-derived DC in vitro.
