MARCO and skin sarcoidosis: Further analyses of data also revealed higher expression of MARCO (Fig. 4H) and lipid metabolism-related genes in sarcoidosis patient macrophages (Fig. 2E; ETHE1, EBP, MSMO1, IDI1, SQLE, LDLR, SCD) from cutaneous sarcoidosis granulomas compared to homeostatic macrophages in non-granuloma regions (Fig. 4I).
