Moreover, miR-155 was found to induce interleukin-22 (IL-22) expression and suppress the C/EBPβ target interleukin-8 (IL-8), two pro-inflammatory cytokines that are also endogenously produced by ALK(+) ALCL cells [44,45] (Table 2 and Table 3). This evidence concerns the gene CEBPB and anaplastic large cell lymphoma.
