To investigate whether these functional implications of PEBP1 expression may stretch beyond DC vaccination and/or metastatic melanoma, we interrogated a large co-expression database of immune cells (immune-navigator) and found that also in this database PEBP1 expression correlated with adaptive immune cell responses and anti-correlated with monocytes and generic immune activation (Figure 4 & Supplementary Table 6). This evidence concerns the gene PEBP1 and metastatic melanoma.
