Compared with IFN-only regimen, no significant increase in HCC risk was found for use of DAA-only (HR, 1.53; 95% CI, 0.73-3.23), DAA + IFN (HR, 1.02; 95% CI, 0.51-2.06), or any-DAA (HR, 1.04; 95% CI, 0.65-1.65).
We further found that RIP3 knockdown results in an increase of MDSCs and a decrease of interferon gamma-positive (IFN-γ<sup>+</sup> ) cluster of differentiation 8-positive (CD8<sup>+</sup> ) tumor-infiltrating lymphocytes (IFN-γ<sup>+</sup> CD8<sup>+</sup> T cells) in hepatoma tissues, thus promoting immune escape and HCC growth in immunocompetent mice.
With CTLA-4 Nb16 stimulation, dendritic cell/hepatocellular carcinoma fusion cells (DC/HepG2-FCs) enhanced autologous CD8<sup>+</sup> T cell proliferation and production of IFN-<i>γ</i><i>in vitro</i>, thereby leading to enhanced killing of tumor cells.
Treating with anti-HN neutralizing mAb induced significant decline in the cytotoxicity of IFN R<sup>-/-</sup> NK cells toward Hepa1-6 cell line (P < 0.05).
In summary, our study suggests that HBV precore protein, specifically the p22 form, impedes JAK-STAT signaling to help the virus evade the host innate immune response and, thus, causes resistance to IFN therapy.<b>IMPORTANCE</b> Chronic hepatitis B virus (HBV) infection continues to be a major global health concern, and patients who fail to mount an efficient immune response to clear the virus will develop a life-long chronic infection that can progress to chronic active hepatitis, cirrhosis, and primary hepatocellular carcinoma.
The present study conducted a meta-analysis to evaluate the effects of adjuvant Peg-IFN-based therapy on the survival outcomes in patients with hepatitis-related HCC after the curative treatment.
In patients with previous HCC treated with curative therapies, HCC recurrence occurred in two (25%) out of eight patients treated with IFN-based regimens and four (21%) out of 19 treated with DAA-IFN-free regimens (P = 1.0).
The present study aimed to investigate the clinical efficacy of single agent S-1 and S-1/IFN-α for HCC patients with extrahepatic metastases in a randomized, open-label, multicenter trial.
However, after 9 months of treatment with subcutaneous injections of PEG-IFNα 2a once per week, the metastatic lung foci gradually shrunk until disappearance and the HCC lesion stabilized without progression.
However, we failed to uncover any significant association between other polymorphisms in genes of IL-12 signaling pathway and HCC risk, including <i>IL18</i>-rs1946518 and -rs187238, <i>IFN-γ</i>-rs2430561, <i>IL12A</i>-rs568408, <i>IL12B</i>-rs3212227 and <i>STAT4</i>-rs7574865.
These results suggested that K6G potentiated the inhibitory effect of IFN-α on HCC cell proliferation through activation of the JAK/STAT signaling pathway by inhibiting SOCS3 expression.
In this study, we investigated the effects of IFN-λ on autophagy, a cellular process closely related to hepatitis C virus (HCV) infection in human hepatoma Huh7 cells.
A systematic review was conducted to identify trials about curative treatment combined with or without adjuvant therapies (interferon, IFN; or transarterial chemoembolization, TACE) for HCC.
Emodin also sensitized the antiproliferative effect of IFN-α in HeLa cervical carcinoma cells and reduced tumor growth in Huh7 hepatocellular carcinoma-bearing mice.
The results are as follows: (1) both ETV and TDF showed long-term efficacy and safety; (2) PEG IFN-α resulted in a greater decline in HBV DNA levels and a higher rate of HBeAg seroconversion; (3) combination therapy with IFN plus two analogues did not elevate the rate of sustained responses; (4) both ETV and TDF showed efficacy and safety with cirrhosis (ETV especially displayed efficacy and safety with decompensated cirrhosis), and (5) suppression of HCC was observed by ETV and IFN.
Here, we aim to detect the anti-tumor effect of a novel gene delivery system - IFN-α2b gene-modified human bone marrow mesenchymal stem cells (BMSCs) in HCC.
We genotyped the rs8099917 single-nucleotide polymorphism in 351 hepatitis C-associated HCC patients without history of IFN-based treatment, and correlated the age at onset of HCC in patients with each genotype.
These results suggest that IFN-α gene-modified NKL cells could be suitable for the future development of cell-based immunotherapeutic strategies for hepatocellular carcinoma.
