We have extracted available data relevant to stage progression of MF and identified 15 genes which were categorized in the following way: cell proliferation (CD70, FYB, LCP2, KIR2DL3, TOX, and TIMP-1), immune checkpoints (HAVCR2/TIM-3, and PDCD1), resistance to apoptosis (GTSF1, and PTPN7), and immune response (CCR4, IL-10, IFNG, GNYL, and NKG7) (Figure 3). This evidence concerns the gene TIMP1 and mycosis fungoides.
