Kuang et al. showed that TAM-released proinflammatory cytokines IL-6 and IL-1β promoted T helper 17 (Th17) cell expansion in HCC, whereas Zhang et al. reported that high levels of Th17 cells correlated with microvessel density and poor survival in HCC patients [32, 61]. The gene discussed is IL6; the disease is hepatocellular carcinoma.
