Aims: Preliminary results from direct ex vivo flow cytometric analysis of peripheral blood from patients with hepatocellular carcinoma (HCC) revealed an immature phenotype and a substantial reduction of circulating dendritic cell (DC) subsets that was associated with increased IL–10 concentrations in serum and with tumor progression. It has been demonstrated that IL–10 exerts itrsquor;s biologic effect on eukaryotic cells by interacting with a specific cell surface receptor resulting in subsequent downstream engagement of the JAK-STAT signaling pathway and STAT3 activation. Moreover, constitutive STAT3 tyrosine…
