More than 50 years have passed since interferon (IFN) was discovered. Until now, the signaling pathway and function of IFN were basically elucidated. IFN has been clinically used for patients with hepatitis B virus (HBV) or hepatitis C virus (HCV). In Japan, pegylated IFN (PEG-IFN) is just approved for patients with HBV related chronic hepatitis. Also, the adding of direct-acting antiviral agents to the combination therapy with PEG-IFN plus ribavirin will improve anti-HCV effect. Another important effect of IFN is a suppression of hepatocarcinogenesis in patients with viral related chronic liver diseases. Maintenance therapy with low dose of PEG-IFN or IFN can improve the prognosis of patients with advanced hepatic fibrosis.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
