Yupingfeng Granule Improves Th2-Biased Immune State in Microenvironment of Hepatocellular Carcinoma through TSLP-DC-OX40L Pathway.

ABSTRACT: The tumor immunological microenvironment in hepatocellular carcinoma (HCC) is the T-helper (Th) 2 dominant inhibition state. Improving the immunosuppressive tumor microenvironment represents an important strategy for HCC treatment. TSLP-OX40L pathway is a target to improve Th2 immunosuppression. Yupingfeng granule (YPF) is clinically used to effectively improve the immune status of HCC. In this study, YPF increased the percentage of mature dendritic cells (DCs) and decreased levels of TSLP, TSLPR, and OX40L in tumor and adjacent tissues of the orthotopic-HCC mice model. This occurs together with the decreased levels of Th2 cytokines and increased levels of Th1 cytokines and Th1/Th2 ratio. In vitro experiment showed that YPF not only increased the percentage of mature DCs and stimulated IL-12 secretion in DCs but also reduced the positive rate of OX40L expression, decreased the proportion of CD4+ IL-13+ T cells, increased levels of Th1 cytokines, and decreased levels of Th2 cytokines from TSLP-treated DCs. In summary, these findings demonstrated that YPF promoted the maturation of DCs, decreased OX40L in TSLP-induced DCs, and improved the immunosuppressive state of Th2 in HCC microenvironment. Our results suggest that the mechanism underlying the improving effect of YPF on the immunosuppression is related to the DC-mediated TSLP-OX40L pathway.

Project description:BackgroundThere is basic research suggesting that Huaier granule can inhibit liver cirrhosis and hepatocellular carcinoma (HCC), but this conclusion has not been clinically verified. We analyzed the distant cancer tissue of two groups of hepatitis B virus (HBV) related HCC with/without Huaier granule, to clarify the effect of Huaier granule on liver inflammation, liver fibrosis, and postoperative recurrence.MethodsWe collected clinicopathological data of HCC patients who received two surgery procedures at Mengchao Hepatobiliary Hospital of Fujian Medical University in China from January 2014 to December 2020. Patients according to taking/not taking Huaier granule after the first hepatectomy were divided into two groups, 51 patients with Huaier granule for more than 6 months after operation (Group A); 56 patients without Huaier granule (Group B). The effects on liver inflammation, fibrosis grade, and postoperative recurrence were compared between two groups.ResultsThe results showed that liver inflammation improved significantly in the Group A [19 (37.3%) cases improved, 31 (60.8%) cases remained unchanged, and 1 (2.0%) case deteriorated] was significantly more than that in the Group B [7 (12.5%) cases improved, 32 (57.1%) cases remained unchanged, and 17 (30.4%) cases deteriorated] (P<0.001). The liver fibrosis in the Group A [17 (33.3%) cases improved, 32 (62.7%) cases remained unchanged, and 2 (3.9%) cases deteriorated] was significantly improved in the Group B [5 (8.9%) cases improved, 45 (80.4%) cases remained unchanged, and 6 (10.7%) cases deteriorated] (P=0.005). The recurrence interval (27.0±21.2 months) in the Group A was significantly longer than that in the Group B (19.0±14.2 months) (P=0.026).ConclusionsHuaier granule can improve liver inflammation, fibrosis, and liver function and prolong the time to recurrence in HBV-related HCC. Given the high rate of postoperative recurrence and poor prognosis of HBV-related HCC, our findings may have useful clinical significance in the prevention of tumor recurrence in these patients.
