Figure Lengend Snippet: The impact of E2F1 on immune cell infiltration and cytokine release in coculture with T cells. (A, B) Correlation of E2F1 expression with infiltration of monocytes, eosinophils, and neutrophils in melanoma patients with primary tumors (A) or metastasis (B) . (C, D) Estimation of CD4 + Th1 and Th2 cell infiltration cells in melanoma patients with primary tumors or metastasis correlated to the expression of E2F1, IL-6 (C) , and STAT3, CD274 (D) . Significant correlations are highlighted in red. (E, F) Cytokine assays of supernatants from different culture/coculture conditions were compared as illustrated showing an E2F1-dependent increased secretion of immunosuppressive type 2 cytokines (E) that was completely reversed after E2F1-KD in melanoma cells (F) . Asterisks indicate transcriptionally upregulated factors. FC, fold change.
