IL6 and hepatocellular carcinoma: Similarly, in hepatocellular carcinoma, CAFs have been described as a major source of IL-6 that affects DC functions through the activation of the STAT3 pathway leading to the generation of regulatory DCs, characterized by low expression of costimulatory molecules and high secretion of immune-suppressive cytokines, which impair T-cell proliferation and promote Tregs expansion [127].
