In view of their markedly increased numbers in the cutaneous MF TME, we focused on further characterizing the myeloid cells, including macrophages (AIF1, CD68, ISG15, C1QC) and dendritic cells (DCs) (CD1C, CLEC9A, LAMP3, LILRA4) (Figure 2A). The gene discussed is CD68; the disease is mycosis fungoides.
