IFNG and neoplasm: In line with this, analyses of proteins in the supernatant of the tissue slices from 14 donors showed that anti‐inflammatory cytokines like TGFβ2 and IL‐10, as well as proinflammatory cytokines like IFNγ, IL‐2, Granzyme B, Perforin, IL‐17A, and IL‐1β were highly secreted by tumor‐border compared with non‐tumor slices (Figure 2B; Tables S3 and S4).
