In the Gide cohort, the ssGSEA scores of CD8+ T cell, DC, and Th1 cells were higher in the PDL2-high group than the scores in the PDL2-low group (Figure 3(b)), and this is consistent with the results of the analysis of other melanoma cohorts (Figures 3(c) and 3(f)). Here, PDCD1LG2 is linked to melanoma.
