چکیده انگلیسی
Hepatocellular carcinoma (HCC) is one of the most common cancers and can be induced by chronic HBV infection. The role of HBV-specific immune responses in mediating tumorigenesis and HCC prognosis is debated. The effect of intratumoral microenvironment on tumor-infiltrating lymphocytes (TILs) is also unclear. Here, we examined resected tumor tissue from 36 patients with HBV-induced HCC. We categorized study cohort based on ex vivo IL-10 secretion by tumor cells into high IL-10-secreting (Hi10) and low IL-10-secreting (Lo10) groups, and found that the Lo10 group was less sensitive to TLR ligand stimulation. TILs from the Lo10 group contained higher frequencies of HBV-specific IFN-g-producing cells and total IFN-g-producing cells, and possessed higher proliferative capacity. Moreover, the proliferative capacity of TILs from the Hi10 group was negatively correlated with IL-10 secretion from tumor cells. Together, our data demonstrated that low IL-10-producing capacity in HBV-induced HCC tumors is associated with enhanced TIL activity.
