IFNA1 and melanoma: In contrast, the melanoma group as a whole showed lower correlation between the percentage of STAT1-pY701-positive lymphocytes following IFN-α stimulation and the expression of CD69 (r = 0.6786, p = 0.0643), while in the healthy group there was no correlation at all in this respect (r = −0.0044, p = 0.9909, Figure S5).
