RXRs have been reported to control macrophage expansion and contribute to ovarian cancer progression.[48] Multiple members of CCAAT/enhancer‐binding protein (CEBP) family, including CEBPA and CEBPD, have been implicated with potential in modulating macrophage activation,[49, 50] whereas we reported CEBPG as a new modulator of TAM development. Here, CEBPD is linked to ovarian cancer.
