Furthermore, several immunosuppressive cells were identified to reprogram the metastatic ecosystem, including FOXP3+ regulatory T (Treg) cells, LAMP3+ tolerogenic DCs (tDCs), CCL18+ M2‐like macrophages, RGS5+ cancer‐associated fibroblasts, and LGALS1+ microglial cells. The gene discussed is FOXP3; the disease is cancer.
